After considering it for some time, I’ve decided to take the plunge and change to an every weekday schedule for The Willpower Engine. My hope is that brief posts on an even wider variety of topics touching on goals, habits, self-motivation, mood, psychology, neuroscience, and personal development every day will be useful and interesting to readers out there who may want to follow the site daily.

This is an experiment; it’s certainly possible that after a few weeks I’ll find the format doesn’t suit as well as I’d hoped and change the schedule to fewer posts (or who knows? maybe even 7 days a week). I’d love to hear your opinion on the matter in comments or using the contact form. 

Having more posts also opens up the possibility that I’ll choose one day to write a weekly post on a specific theme, with writing and weight loss being the lead contenders right now. Of course I’d be very much interested in your opinion on that subject, too, or in fact in any comments about the site and its contents.

That’s all for now … but see you here tomorrow!

Since I started getting serious about fitness, there have been two kinds of health habits I’ve been trying to change and improve, and they’re the same two that we hear all the time when people talk about weight loss: eating and exercise. I can tell you from experience that eating well and exercising regularly work, if they’re done the right way. What I haven’t understood until now is why picking up the exercise habit was so much easier than changing my eating habits.

In both cases, I’m trying to strengthen good habits (getting regular exercises, choosing healthy foods to eat), but only in the case of eating am I also trying to quash bad habits (eating the wrong foods or too much of the right foods).

When I started exercising, I got into good habits within a few months, habits that have improved slowly over time ever since. Eating, however, has been another story. In terms of good eating habits, I’ve been building those much like my exercise habits. Some of the lunches I’ve been eating are so filling yet light and nutritious, they’d make you weep. Well, maybe not you, but certainly someone with a sentimental streak for healthy lunches.

My bad eating habits, though, haven’t been going away at the same rate as my good eating habits have been coming in. Sure, they’ve been diminishing over time, but if the good habits had had anything to say about it, the bad habits would have been beaten to an unrecognizable pulp years ago. So what’s going on here?

Research to the rescue: A study by psychologists Bas Verplanken and Suzanne Faes gives evidence that forming a good habit to reach a goal doesn’t necessarily do anything to get rid of bad habits that might get in the way of that same goal. Verplanken and Faes make sense of this with the idea of “implementation intentions”–plans to do something specific in a specific kind of situation. This research seems to show that implementation intentions (like “prepare a healthy lunch in the morning and bring it in to work instead of buying something”) are much more useful for forming habits than general goals (like “eat a healthy lunch”). When you think about it, this makes sense: building habits is about doing something over and over again. If a person hasn’t decided exactly what to do exactly when, there’s a lot more in the way of the behavior that person is trying to repeat.

Implementation intentions, though, only cover specific circumstances and specific behaviors. So my nifty ideas for lunch can certainly help me choose a healthy lunch over an unhealthy lunch–but those same ideas will have little or no effect on whether I decide to buy some kind of high-calorie food to munch on an hour later.

The upshot seems to be that good habits can help destroy bad habits only if there’s no way for both habits to happen together. Bad habits can be overcome, and there are many tools on this site that offer ways to overcome them, but to make the best progress on that front, it becomes important for us to separate out the specific habits we’re trying to change or acquire, good and bad, so that we know which bad habits need to be tackled directly and which we can depend on good habits to crush.

I recently noticed that I have the habit, sometimes, of living approximately one minute in the future. This is a problem. I’ll explain:

Of all the focus and motivation-related skills I could be developing, the one that helps me the most when I practice it and causes the most harm when it’s missing is mindfulness. When I take time to be aware of what’s going on around me, what I’m doing, what I’m thinking about what I’m doing, what’s really important to me, and from all that what choices suit me the best, I make some terrific choices. When I lose track of too many of these things for too long … not so much.

The question of how well mindfulness works has a lot to do with how much effort and attention go into it, so the problems come for me mainly when I let my attention be taken up too much by other things.

Recently I was doing my best to apply mindfulness to how I eat. This probably sounds like a relatively unimportant, navel-gazing exercise, but since eating is one of the things that in the past I’ve done least mindfully, for me it’s something that I benefit from working on regularly.

What I noticed about myself was that while I was eating something I enjoyed, I wasn’t paying the most attention to the bite I was actually eating. I wasn’t even paying attention to the next bite: no, the bite I was focusing on was the one two bites ahead. Somewhere deep down I seem to still have a concern that the food will all just run out all of a sudden. And who knows? Someday I may live in a time and place where there’s a famine and there isn’t enough food. For an adequately employed American in 2010, though, that attitude is ridiculous.

And yet, I began to notice that whenever I was on my next-to-last bite, I stopped enjoying what I was eating and felt as though I had no food left. This is while I’m still chewing and have another bite to go, mind you. I was living two bites in the future, and even when there was still food two bites away, it wasn’t food I was eating–all I was enjoying then was the fact that there was still food available.

I don’t eat like this all the time, or even necessarily most of the time. But when I’m not paying attention and letting my least useful long-term eating habits get the best of me, there’s a disconnect between me and my food–which may explain why until the last couple of years, while I ate healthy food, I didn’t have a good sense of how much I should eat or when. That’s changed with effort and practice, fortunately, but some of the attitudes that gave rise to the problem in the first place are still present, even though they’re diminished.

The problem of living a little bit in the future can crop up anywhere: watching the clock during the work day and not being willing to be happy until it’s time to leave; working on a project and not allowing a sense of any accomplishment until the project is done (if then); and so on. If you find you’re having trouble enjoying something, it can be useful to pay attention for a moment to where your focus is: is it on what’s going on now, or is it on some imagined payoff, deadline, beginning, or end?

That’s not to say we should always live in the moment: always doing that is neither wise nor practical, and I talk about the reasons this is true in this article. But living slightly out of kilter with the moment often isn’t a good strategy either, and sometimes all it takes to be happier and reduce stress is to set the clock back a minute or so.

With fellow Blue Wave students after earning our black stripes (last rank before black belt), October 2009

After flirting with consistent exercise for two decades, in 2005 I took advantage of being in Florida to finally start running regularly. That experience, which I talked about in a

Audio clip: Adobe Flash Player (version 9 or above) is required to play this audio clip. Download the latest version here. You also need to have JavaScript enabled in your browser.

for Jacksonville, Florida NPR affiliate WJCT, completely changed my understanding of exercise. It turned out that the very beginning of exercise, getting into the groove, was much harder than continuing–and that far from being unrelenting torture, regular exercise could actually be enjoyable.

I ought to have recognized this already: after all, soccer had been fun in grade school, ultimate frisbee entertained me during college, and I’d enjoyed fencing classes in my twenties. But neither running nor any of these other activities prepared me for what would happen when I took on a new kind of exercise in late 2006. For me, getting involved in Taekwondo was to running as April in Paris is to June in Cincinnati.

Martial arts as a family sport
A little background: I studied Uechi Ryu karate for about a year at college and had enjoyed it enough that for years I had it in the back of my head that I’d eventually want to pursue martial arts again. By 2006, my son had gotten old enough that we were looking for a program for him as well. I had assumed we’d study karate, in different classes, but when my son was invited to a friend’s birthday party at Blue Wave Taekwondo in Burlington, Vermont (the town where we lived), it was immediately obvious that this was the place for us to try. For one thing, they taught classes that parents and kids could attend together, a possibility I hadn’t even thought of. For another thing, my son’s friend’s family couldn’t say enough about how friendly, well-organized, and instructive the school was. To top this off, the school was (and still is) run by Master Gordon White, a personable sixth-dan black belt who had fought on the U.S. National Taekwondo team and won medals in international competition.

I’m not suggesting Taekwondo is every person’s ideal exercise. It’s social, very energetic, rigorous, formal, demanding, and a little rough. My older sister loves spinning and rollerblading; my younger sister loves dancing; and my father prefers canoeing, kayaking, and cross-country skiing. So I’m not so much suggesting you run out and start taking Taekwondo (although it’s not a bad idea for a lot of people), but that if you don’t yet love the kind of exercise you’re doing, there’s a good chance you just haven’t found the right kind of exercise yet.

Why Taekwondo works for me
Taekwondo offers some unusual benefits that fit my needs well. I like the people I spend time with at the dojang (Taekwondo gym), which helps. Taekwondo as practiced at Blue Wave is rigorous interval training (probably the best general kind of exercise for weight loss), and it builds muscle as well as providing a lot of aerobic exercise.

Some of the greatest benefits for me, though, are mental instead of physical: the need to always improve my fundamentals (kicks, strikes, blocks, stances, and so on) exercises parts of my brain that I suspect would otherwise be neglected. And while we’re in class I’m usually so engrossed at trying to master whatever we’re working on that the time flies by. As I talk about in my post on getting into a state of flow, some of the basic elements we need to become engrossed and driven in what we’re doing are challenge, specific goals, and constant feedback. All of these elements are available when a good instructor is teaching a complex physical skill, like martial arts, dancing, or fencing. Not everyone will connect with those activities in the ways that are needed to establish flow, but the opportunity is there.

To put the same thing more simply: Taekwondo keeps me so interested, I don’t greatly care how much work I’m doing to practice it.

Why Blue Wave works for me
Not all martial arts–or all Taekwondo schools–are created equal. Different martial arts offer different advantages, such as the directed force of Aikido; the intense focus of karate; the powerful physical grappling of judo; or the flow and speed of kung fu. Different martial arts will attract different kinds of people, although it’s important to understand that different martial arts also provide different kinds of workouts: for instance, not all martial arts are very helpful for weight loss.

Blue Wave teaches forms and fundamentals as well as Olympic Style sparring, which is a very energetic, physically demanding type of contest between fighters wearing padded safety gear. Olympic Style sparring is fairly safe and is practiced in tournaments from the local to the international level, including, of course, at the Olympics. To the best of my knowledge (understanding that my experience is limited), no other martial art offers such a well-defined and safety-conscious sport of sparring.

So Olympic Style Taekwondo sparring for me is as much a sport as a martial art, which gives more direction to my training and provides more ways to enjoy Taekwondo. But many Taekwondo schools don’t teach Olympic Style sparring, or they focus on other elements of Taekwondo, or they practice a type of Taekwondo that is not based on rigorous traditional practices. None of these kinds of schools would work nearly as well for me as Blue Wave would, although Blue Wave is far from unique: there are many excellent Taekwondo programs around the country and the world.

I could go on about what I like about Blue Wave, but if I’ve done what I intended, I’ve shown at least one example of finding a kind of exercise that really fits the person doing it, enough to provide a glimpse of what April in Paris looks like. Here’s hoping you’re already there, or if not, that April comes soon.

Just before Thanksgiving, I posted How Not to Blow a Diet Over the Holidays, which contained the best information I had to offer about holding to a difficult course of fitness and weight loss during a time of year crammed with distractions, temptations, and surprises. Toward the end of the post I said, “Today I weigh 182 pounds. I’ll update this post in early January to let you know how it came out for me: I expect to have lost at least a few pounds.” Was my prediction sound? And just how useful did I find my own recommendations?

What worked
Well, my rash declaration definitely helped me focus my attention and reminded me to use the best knowledge I have. (After all, just knowing something isn’t the same thing as making active use of the knowledge), and the self-motivation skills I’ve been researching and writing about seem to have done the trick: my scale this morning tells me I weigh 177, five pounds less than I did a few days before Thanksgiving. I’ve lost roughly a pound a week over that time, most of it in the beginning of December, and am very close to my goal fitness level. (Exactly how close, I can’t be sure, as I’m not aiming for a number on the scale, but instead for a level of visible fitness.)

Did my pre-Thanksgiving strategies help me? Absolutely. I made a point of bringing food I could eat to celebrations and meals, planned what to eat ahead of time (including limits), took special care to track what I was eating, and talked freely about what I was doing to get support and to increase the potential rewards of sticking with it.

Unexpected complications
So did my own pre-holiday advice eliminate all trouble for me? Definitely not. The two problems I wasn’t expecting seem obvious in hindsight, but when I was making my plans, all I was worried about was the food that would be available to me.

The first of the surprise problems was time for exercise. I generally try to exercise as close as possible to every day. Over the holidays, there were a number of days when I would be with friends or family in all of my available time, and the idea of getting everyone up after Christmas dinner to go for a family run somehow didn’t seem very appropriate to me. Also, my habit of taking 3-5 Taekwondo classes a week was interrupted by holiday closures of the dojang (Taekwondo gym). So I squeezed in exercise when and where I could, more than once getting on the elliptical trainer or doing home Taekwondo practice well after 10:00 at night. In future, I’d want to plan better for these scheduling challenges, probably getting in some morning exercise instead of following my usual evening schedule–but I will also know to expect that I’ll get less exercise over the holidays, and to a limited extent, that’s OK with me.

The other problem I faced was a one-two punch: I would arrive home tired (though cheerful) after having eaten at irregular hours and spent the day with family or friends. I don’t know about you, but for me the combination of being tired and being off my normal eating schedule is a very bad one: it tends to make me feel hungry and inattentive, which means I’ll often just take whatever I think of first and eat it–hardly a recipe for weight loss success. A day like this broke my winning streak of keeping under 1700 calories a day and logging everything I ate, which had gotten up to 42 interrupted days. I’m now in the early days of a new winning streak, and have high hopes that it will carry me across my personal finish line as I rack up the days.

One good holiday season may be the most I’ll ever need
As I write this and do my best to extract knowledge for future (an example of keeping a feedback loop), I’m realizing that if all goes well, it’s very, very likely that when the 2010 holidays come around, I’ll have been on maintenance for quite a while, and while I’ll need to continue to be careful, I won’t need to be nearly as careful as I am now. In other words, losing weight over this past holiday season together with continued effort may mean I’ll never have to be quite so careful over the holidays again. Even if I had done no better than maintain my weight during that time, the same result would probably apply. For many people who are getting in shape, one really successful holiday season may be the make-or-break period for the entire process.

How did things go for you over the holidays? Any special difficulties or unusual accomplishments?

Regardless of how the holidays came out for you in terms of your health, we’re now at a time of year that is probably better suited to renewing commitment and redoubling efforts than any other, and we can use it to launch ourselves forward. Here’s to a powerfully motivated New Year.

It was in April of 2009 that I started the Willpower Engine. 132 posts and more than eight months later, I’ve been interested to see what kinds of articles have gathered the most attention. And while the reasons one post might get seen more than another are a little chaotic–more of an indication of successfully getting the word out than of anything–it’s also true that some of my favorite posts show up on this list.

So here, without further ado and with a few brief notes, are the top 10 Willpower Engine posts this year.

#10 – How Feedback Loops Maintain Self-Motivation – Feedback loops are one of the most useful of all tools for maintaining motivation. Keeping focus and really thinking about our recent experiences in light of our goals can keep those goals alive and moving forward in our minds.

#9 – How Much Sleep Do You Need? 8 Hours Isn’t for Everyone – I had been wondering for years if “8 hours” was really the amount of sleep everyone needed, and it turns out it isn’t. The way to learn how much really is needed turned out to be very simple.

#8 – Do you have enough talent to become great at it? – The books that informed this post were revelatory for me. Our culture takes the existence of natural talent as a given–yet the idea of “talent” turns out to have some serious flaws, which create some incredible opportunities when we realize them.

#7 – How To Improve Willpower Through Writing Things Down: Decision Logging – When I first tried Decision Logging, I thought it might be a magic bullet. It turns out to require too much time and attention to do all the time, so it’s not a magic bullet–but it can give self-motivation a very powerful boost by focusing attention and sparking insight.

#6 – How to Strengthen Willpower Through Practice – The idea of willpower as a muscle that can be strengthened by exercising it has some limitations–but in many ways, this picture of willpower holds true, and strengthening our natural good inclinations is a very valuable things to be able to do.

#5 – 7 Key Self-Motivation Strategies for Writers – This post was an early precursor to my free eBook, The Writing Engine: A Practical Guide to Writing Motivation, and it offers some of the most immediately useful advice I have for writers who want to write more.

#4 – How Long Does It Take to Form a Habit? – There are a lot of places out there on the Web that make claims as to how long it takes to form a habit, but very few seem to be based on anything more than someone’s rough guess. Fortunately, there is a bit of research done to look at the question more carefully, and this post is based on that research.

#3 – Broken ideas and idea repair – Like feedback loops, idea repair (called “cognitive restructuring” in the psychological literature) is one of the most useful skills this site has to offer: it provides a way to understand negative emotions and bad moods and turn them around. I later followed this post up with some additional, practical information in How to Detect Broken Ideas and How to Repair a Broken Idea, Step by Step.

#2 – 6 Key Self-Motivation Strategies for Losing Weight – Weight loss has been one of the key areas where I’ve made use of self-motivation in my life, and with two thirds of adult Americans being overweight, I’m in good company for wanting to make that change. As demoralizing as trying to lose weight can be, it is possible, and this post offers some of the best information I have as to how to best do it.

#1 – How Tools and Environment Make Work into Play, Part I: The Example of Scrivener – It may seem surprising that the most popular post on the entire site focuses as much on a particular product as it does on a motivation strategy, but the more I think about it, the more it makes sense to me that this post is read as much as it is. Any really good tool–like Scrivener for a writer, or a really excellent brush for a painter, or the arguably industry-changing Red One camera for an indie filmmaker–provides a whole lot of motivation with very little of the usual investment of time and effort. Money aside, who doesn’t want instant motivation improvement?

And there are the most popular Willpower Engine posts for the year. What about the coming year? Your comments, ideas, and messages are always appreciated and of interest. Write me if you have ideas about what kind of article would be of the greatest use to the greatest number of people in 2010.

Recently I came across an assertion that seriously disturbed me: that when we’re “hungry” we “have to eat.” This claim bothered me because it (like a lot of misguided dieting advice) was in a popular diet book, because I think many people believe it, and because it’s wrong.

Pictures of Food
The source of the statement was Dr. Shapiro’s Picture Perfect Weight Loss, a book that offers weight loss advice, examples, and especially a large number of full-color photo spreads of different foods that contain the same amount of calories. For instance, Shapiro graphically displays how a person could eat four ears of corn on the cob and get the same calories as in one medium serving of french fries. I found the pictures interesting and somewhat instructive, although the calorie counts need to be understood as examples (for instance, he counts 70 calories for a slice of whole wheat bread, whereas the loaf in my fridge is 110 calories per slice) and although Shapiro pays only limited attention to nutrition. Mainly, he wants to show that the physical amount of food you eat can vary a lot for the same number of calories, and does that well.

But Shapiro makes a number of imperfect assertions about weight loss, and the one I felt was particularly damaging was this: “The urge to eat is a need that must be filled.” (The emphasis is Shapiro’s.) He continues, “If we don’t respond to that urge, the need-to-eat feelings … will get the upper hand.”

He goes on to reassure the reader that this doesn’t mean all is lost, because the reader can learn to choose much lower-calorie foods and eat whenever they like. The fact that a person can eat much more for fewer calories is certainly true, though the idea that no restraint in eating is necessary in order to lose weight and keep it off is, for many of us, simply wrong.

Misconceptions about hunger
I’m surprised a little that Shapiro says this, because he acknowledges some of the complexity of hunger (which is really a variety of physical and psychological feelings), although he seems to complete miss or ignore some important psychological elements. Ideas about “needing” to eat, including Shapiro’s claim that hunger means we “have to” eat and there’s nothing we can do about it are all broken ideas, also known as cognitive distortions. In other words, most of our behavior is driven not by what we experience directly, but by what we tell ourselves about what we experience.

In essence, Shapiro is saying “I don’t know how anyone can possibly not act on hunger, so it can’t be done.” Put in that way, I think the flaw is obvious: just because Shapiro doesn’t know how to handle hunger other than by administering food doesn’t mean that nobody does.

For Shapiro’s information, and that of anyone else who shares his belief, I’d like to point out that hunger is always temporary, and that if you ever want to find a way to put hunger off, there are 24 of them here.

Different People Succeed in Different Ways
I don’t mean to pick on Shapiro especially. I think his food comparisons are very useful despite some minor limitations, and frankly he seems to be like a lot of professionals who have seen successful weight loss (especially those who have only seen it from the outside) who seem to feel that because it’s been accomplished one way, there’s no other possible way to do it successfully. I find the same idea in many books on writing, even by very talented and successful writers: “This is the way to do it. If you don’t do it this way, you’ll fail.” If psychology teaches us anything, it’s that different people succeed in different ways, so what I am doing my best to offer with this site is the other approach, which is to say: “Here are all of the tools for tackling this task that I can find. Take the ones that work for you and run with them.” And if one of those tools is being able to outsmart hunger when you don’t want to eat, all the better.

Let’s say someone has been working on losing weight, but over Thanksgiving gave up and ate way, way too much. Or they were going to write 50,000 words this November for NaNoWriMo, yet here it is a few days from the end and they’re only 28,000 words in. Or they’ve gone back on a promise, done something they had vowed to stop doing, failed to stick with a new habit that they really wanted to keep up, or in any other way completely wiped out.

Often in situations like this, we’ll start telling ourselves in one way or another that whatever plans we have are now ruined. The promise is broken, the diet has failed, the project has flopped. It’s easy to lose all enthusiasm at this point and give up, to conclude that people who are successful at achieving difficult goals don’t have these kinds of setbacks. That conclusion would be wrong.

It’s true that failures on the way to a goal can cause a more than their share of trouble. If I’m trying to build a new habit, interruptions to the thing I’m trying to make habitual will make it take longer for the habit to form. If I suffer a setback, it can often create additional obstacles, because slip-ups erode momentum in the same way that taking initiative builds momentum.

Yet it’s clearly typical–in fact, I’d hazard a guess that it’s almost inevitable–for a person to have some failures on the way to successfully building a new habit or pursuing a goal if that goal is sufficiently challenging. For example, according to the American Cancer Society, “most of those who attempt [to quit smoking] cannot do it on the first try. In fact, smokers usually need many tries — sometimes as many as 8 to 10 — before they are able to quit for good.”

Another way to put it, as strange as it may sound, is that the kind of person most likely to succeed at a goal is someone who has already been working on it but has failed one or more times.

Yet knowing this probably doesn’t make you automatically feel like a winner. What will do that is getting back to working on your goal right away. It’s easy to fall for reasoning like “I’ve blown it anyway–a little more won’t hurt” or “I’ll recharge my batteries before I take another crack at it,” but that kind of logic is usually flawed, because whenever we let a setback “give you permission” to stick with old, bad habits for a while, or to stop something we were working on, we are strengthening and refreshing the behaviors we don’t want and letting the behaviors we do want fade in our minds. The neural connections we’re building by prolonging the interruption will make it easier to make wrong choices and harder to make right choices. We’re also often doing more damage that will have to be repaired once we get back on track, making restarting even harder.

We can learn from setbacks by analyzing what went wrong and coming up with ways to act differently in future. And we can cut off failures, keeping them to the shortest span possible, so that they become just blips on the graph. In practical terms, all a setback does is take away a little progress and lower our spirits. We can gain that ground back and raise our spirits at the same time by renewing our plans to pursue our goals and not letting the problems claim any more of our lives than they have to.

The 9 Truths About Weight Loss
by Daniel S. Kirschenbaum, PhD

For anyone interested in weight loss, certain essential questions tend to come up again and again: Are there any shortcuts? What exactly do I need to eat? Do I have to exercise? If so, how much, how often, and in what way? Is it even possible for me to lose weight? What if I lose weight but then gain it right back? Does the process have to be painful? Will it make me happy? Why haven’t I been able to lose this weight and keep it off?

In The 9 Truths About Weight Loss, Professor of Psychiatry Daniel Kirschenbaum tackles–and in my opinion, largely answers–these questions and many others. Kirschenbaum is the director of the Center for Behavioral Medicine and has consulted for Weight Watchers and the U.S. Olympic Team, among other organizations, in addition to coaching literally thousands of clients successfully through the weight loss process. He really, really knows what he’s talking about, and unlike many diet “experts” generally doesn’t have a system to sell. His 9 Truths boil down to something like this: yes it’s hard, but it’s possible if you can find a way to commit to working hard at weight loss consistently and permanently.

In a little bit more detail, here are his 9 Truths, paraphrased:
1. Our bodies are designed to resist losing fat
2. However, the right behavior can overcome this biological tendency so that we can lose weight
3. Weight control is as feasible as any other athletic challenge
4. The three stages of weight control are Honeymoon, Frustration, and Acceptance
5. It’s possible to eat a very low-fat diet and still not feel overly hungry
6. Tracking your eating and exercise habits is key to weight loss
7. Exercising every day (or close to it) is a very effective route to weight loss
8. Eating reasonably can fit comfortably with managing stress
9. It’s easier to maintain weight loss you’ve already achieved than to lose weight in the first place

While I think Kirschenbaum’s book is excellent, I do feel it has some problems, most of them having to do with Kirschenbaum confusing some reasonable but not necessarily essential behaviors he has counseled his successful clients to take with required behaviors for weight loss. Many of Kirschenbaum’s conclusions about weight loss–for instance, that everything you eat “counts,” that the human body resists losing fat once it has acquired it, etc.–seem to be spot on. Others seem to be just his preferred way of advising people to lose weight.

As one example out of many, Kirschenbaum states “Almost all of the thousands of weight controllers with whom I have worked over the last twenty-five years, and who have succeeded at this difficult enterprise, have exercised primarily in the morning,” implying that this timing is important to successful weight loss. Speaking as someone who started losing weight four years ago, who has so far lost well over 50 pounds, and who has never gained back any significant amount of weight in those four years, I feel I should mention that I exercise almost exclusively at night, as do the lion’s share of other succcessful exercisers I know. I won’t debate the relative merits of morning vs. evening, and in fact it may be better to exercise in the morning if you can manage it, but the fact is that exercising very regularly seems to be much, much more important than exactly when you do it.

Kirschenbaum offers a variety of these recommendations that, based on my own experience and/or research I’ve come across, seem to be unnecessary, but the recommendations generally don’t seem to be problematic and are minor in scope. Reading the book with a little skepticism for very specific recommendations but profound respect for Kirschenbaum’s key points will improve almost anyone’s understanding of weight loss.

Kirschenbaum repeatedly talks about weight loss as an athletic goal, which is one of the most positive and useful ways of looking at it I’ve heard. Like a professional athlete, someone who wants to lose weight needs to become profoundly proactive about diet, exercise regime, and motivation. More than that, the goal isn’t to achieve some imagined ideal point and then stop doing anything, but rather to get to one’s highest level of performance and stay there.

Another area where Kirschenbaum shines is in providing solid information on motivating ourselves to lose weight, although he covers only certain facets of this very big subject. This leads into the only other major reservation I have about the book, which is that Kirschenbaum always talks about weight loss as a strenuous and often unpleasant thing to do. He’s certainly right that it takes a lot of effort and goes against the grain for most of our typical behavior, but the image he conveys of successful weight-controllers struggling grimly against an unforgiving biology fails to fully take into account the incredible array of ways we can motivate ourselves, change our thinking, and even take on new beliefs. My own weight loss efforts, which have become better-focused and more effective thanks to Kirschenbaum’s book, are definitely effortful–but they’re anything but unpleasant. For every ten or fifteen minutes of mild suffering at having to wait because it’s not time to eat yet, I get hours of pleasure at having a more energetic, leaner, and more capable body. Kirschenbaum does a great job of showing how and why weight loss is possible; any of us who work at weight loss will have to work on our own (or use resources like The Willpower Engine) to learn how and why weight loss can be enjoyable and fulfilling.
