Why willpower isn’t enough

Happy New Year!

How are those resolutions coming along? One week into January and most of us are still sticking to our healthy diet and exercise regimens. By the time March rolls around, of course, almost 80% of those well-intentioned plans will have been abandoned.

I think the problem is that we place far too much faith in our willpower — which, as research shows, probably won’t be enough to power you through the tough times.

Willpower: A Limited Resource?

According to researchers Roy Baumeister and Kathleen Vohs, most of us have a relatively limited supply of willpower. When we call on our willpower to help us resist a temptation, we actually deplete our reserves, leaving us less able to resist the next temptation. Not only that, but the mental energy we spend exercising our willpower drains our capacity to perform other cognitive tasks!

Let’s say, for example, that you show up at your weekly staff meeting to find that Linda has brought a batch of her famous homemade chocolate chip cookies. The cookies smell delicious and you know from previous experience that they taste every bit as good as they look and smell. Nonetheless, you’re determined to stick to your resolution to avoid sweets. Ninety minutes later, the meeting is finally over and you’ve made it through without a single cookie! Good for you!

Unfortunately, the effort it took to NOT eat those cookies during the meeting made you less able to concentrate, problem-solve, and contribute at the meeting. And then, on your way out of the conference room, you walk by a bowl of chocolates that someone left on the counter. They’re not even particularly good chocolates–nowhere near as tempting as Linda’s cookies. But the fact that you have just spent 90 minutes resisting those cookies actually makes it more likely that you’ll succumb to those cheap chocolates.

Oh, the humanity!

Strength Training for Your Willpower

Some psychologists argue that willpower is a bit like a muscle. When it’s asked to do some heavy lifting, your willpower can become fatigued, just like your bicep gets tired after too many curls,

However, just as you can gradually build up your bicep with strength training, you can also increase your willpower by exercising it. Baumeister believes that you can strengthen your willpower by consciously doing things that are contrary your usual habits — such as brushing your teeth with the opposite hand or driving a different route to work.

Carol Dweck, from Stanford University, on the other hand, thinks that the idea of willpower as a limited commodity becomes a self-fulfilling prophecy. When subjects are primed to think of willpower as a renewable, self-replenishing resource, they seem to have more of it.

Just as you can build up your bicep with strength training, you can also increase your willpower by exercising it.

Personally, I think that the truth lies somewhere in between. Some people seem to have greater reserves of willpower than others. This may be due to nature, nurture, or a bit of both. And I don’t doubt that willpower can be enhanced with the right kind of training — at least to a certain extent.

Nonetheless, instead of relying entirely or mostly on willpower, I think makes sense to supplement our resolve with other strategies to increase our chances of success.

3Tricks for the Willpower Challenged

Trick #1: Engineer your environment to remove temptation 

Don’t use up valuable willpower resisting those Oreos and potato chips in the cupboard. If you don’t want to eat it, don’t bring it into the house. If you must  have it in the house, put it in a cupboard or closet that is out of sight and difficult to reach. If, after all that, you decide to indulge, serve yourself a single portion into a small bowl and put the rest away. Most people think that they are far too smart for these sorts of simplistic things to make a difference. But study after study demonstrates that they work.

For more on engineering your environment for success, see my episode on Why We Overeat.

Trick #2: Use positive redirection

Anyone who has ever spent time with a 2-year-old knows the power of positive redirection.  Instead of telling a toddler to stop pulling the cat’s tail,  you distract him with a different toy or activity. And, let’s face it, when it comes to changing our eating habits, most of us are operating on the level of a 2-year-old.  So instead of obsessing about what you’re trying not to eat, focus on things you’d like to eat more of.

For more on positive redirection, see my article Shift Your Focus to Make Dieting Easier

Trick #3: Keep it simple

For some reason, when we make up our mind to lose weight or get in shape, we’re often attracted to complicated regimens that have lots of very specific rules and requirements. Subconsciously, we seem to believe that the more elaborate the program — and the bigger the departure from our current habits — the more likely it is to be the one that finally works.

This is a trap.

The more complicated the diet, the bigger the departure from our normal routine, the more rules and restrictions there are and the more decisions we’re required to make, the more likely we are to crash and burn.  If you want to make it stick, keep it simple.

Shorter Days Have You Craving Carbs? Try This Instead.

exercise.jpgAs the temperatures dip and the days get shorter, comfort foods may seem like just the thing. If you find yourself craving carbohydrates at this time of year, it may be due to a seasonal dip in serotonin levels. Eating carbohydrates tends to increase serotonin production, which can elevate your mood–but only temporarily. In a few hours, you need another fix. By the time winter is over, you may have packed on a lot of carbohydrate-fueled pounds.

A better way to stimulate serotonin is with regular exercise.  Exercise stimulates serotonin production with no carbohydrate hang-over. Instead of gaining winter weight, you might even trim down.  Overcoming your Fall fatigue and getting yourself moving may take some self-discipline at first. But the rewards, in the form of more energy and a brighter mood, come quickly.

Can Diet and Nutrition Help You Get Pregnant?

Fertility medicine, which barely existed 50 or 60 years ago, is one of today’s fastest growing medical specialties. Many couples are waiting longer to start their families these days and as the age of wannabe parents increases, so do their fertility troubles. But are there other factors driving increased fertility problems? Could the modern diet or poor nutrition status be partly to blame?

This article also available as a podcast. Click to listen.

I recently attended an educational session with Jorge Chavarro, the Harvard doc who authored the best-selling book The Fertility Diet. Chavarro’s dietary recommendations are based on data from the Nurse’s Health study, which tracked the diet and health of 18,000 women over the course of several years. Some of those women had children during the years that data was being collected while others tried unsuccessfully to get pregnant.

It’s important to realize that Chavarro didn’t treat any of these women for infertility, nor did he make any nutritional recommendations to them. He simply compared the diets of women who got pregnant to those who couldn’t, to see if he could identify any trends. And he did, in fact, identify several factors that the women who got pregnant had in common.

The program outlined in The Fertility Diet is simply a summary of those factors. The hope is that if you mimic the diets of women who get pregnant, you too will get pregnant. I say the “hope” instead of the “promise” because this claim has never actually been tested in a systematic way. But, with that disclaimer in mind, let’s take a look at the factors associated with greater fertility.

Dietary Factors Linked to Fertility

Chavarro documented that women whose diets were highest in trans fats, refined carbohydrates, and animal protein were the most likely to suffer from infertility. Women who followed a more Mediterranean-style diet (higher in vegetables, legumes, whole grains, nuts, olive oil, fish, and so on) were least likely to experience infertility.

Nothing earth-shaking here: The dietary pattern associated with increased fertility is a nutrient-dense diet that’s low in junk and processed food. When you take good care of yourself, all your systems will probably function better, including your reproductive system.

Does Butterfat Help You Get Pregnant?

There was, however, one finding that surprised researchers, because it doesn’t line up with widely held notions about “healthy” diets. Women who ate high fat dairy seemed to be more fertile than those who ate low fat dairy products. In his talk, Chavarro threw out a couple of hypotheses…..

First, low fat dairy products are higher in milk sugar, or lactose. During digestion, lactose is broken down into two simpler sugars: glucose and galactose. The second of these, galactose, has been shown to interfere with ovarian function. The idea is that women who drink low-fat dairy products will be exposed to more galactose and that this might inhibit conception. Interestingly, if you are lactose intolerant, your body is not able to break lactose down and you’d be protected from this effect. Then again, drinking milk would probably give you a tummy ache so you’d probably be avoiding it anyway.

The other theory Chavarro proposed was even more intriguing: Cow’s milk comes from pregnant cows and contains various bovine hormones associated with pregnancy and lactation. Because hormones are fat soluble, whole fat dairy products (even organic ones) would have higher levels of these hormones than low fat dairy. Although many people think of hormones in milk as something to avoid, Chavarro wonders whether the natural hormones in dairy fat might actually play a supportive role in human reproductive function. Mind-blowing, huh?

Exercise, Body Weight, and Fertility

If you’re overweight, you may want to work on losing the weight before working on getting pregnant.

Chavarro’s research suggests that switching to full-fat milk and yogurt might boost your odds of getting pregnant. But this is not a free pass to start pounding the Ben and Jerry’s. Being overweight or obese will dramatically lower your chances of getting pregnant. In fact, the rise in average body weight is a major factor in rising infertility rates. Chavarro’s analysis confirms that women who were at a healthy body weight and who exercise 30 minutes a day are much more likely to get pregnant.

But there is a bit of a catch-22 for overweight women who want to become pregnant. As clinical dietitian Judy Simon points out, fertility can be suppressed during active weight loss. When calories are sparse, she says, the body prioritizes its use of energy, and reproductive function takes a temporary hit. This affects both women who are underweight and women who are cutting calories in order to lose weight.

If you’re overweight, you may want to work on losing the weight before working on getting pregnant. Not only will you probably have an easier time getting pregnant once your weight is stable, but both you and your baby will be healthier if you start your pregnancy at a healthy body weight.

Will Following the Fertility Diet Help You Get Pregnant?

Obviously, improving your diet or nutritional status can’t hurt your chances of getting pregnant—and it may well help. There’s also a widespread belief (and a lot of anecdotal evidence) that stressing about getting pregnant is one of the biggest obstacles to conception. Fertility docs are always telling their patients to relax. It could be that following a so-called “fertility diet” also has a powerful placebo effect—helping couples feel more optimistic and giving them something to focus on while they wait for nature to take its course.

Something new for your pantry: Tea seed oil

Tea seed oilNot to be confused with tea tree oil, tea seed oil is an edible oil pressed from the seeds of Camellia oleifera, a small shrub related to Camellia sinensis, or tea plant.  I recently received some samples from Arette, a company that distributes organic tea seed oil.  As this product may be unfamiliar to many of you, I thought I’d post a quick review/introduction.

Culinary Features

Tea seed oil has a thin, light texture, similar to almond or grapeseed oil–much less viscous and “oily” than, say, olive oil.  The flavor is also very light and clean.  There are times, of course, when you’d want a more robust oil–but for times when you’re looking for a light touch, tea seed oil fits the bill.

Tea seed oil makes a light, delicate vinaigrette, perfect for delicate greens that might be weighed down or overwhelmed by the flavor of a heavier or heartier oil.  Vegetables sauteed in tea seed oil remain almost dry to the touch, without the oily sheen you’d get from a heavier oil.

Nutritional Properties

Tea seed oil also has some unique nutritional properties. Although the texture reminds me of grapeseed oil, tea seed oil has a very different fatty acid profile. Continue reading “Something new for your pantry: Tea seed oil” >

This week: garcinia, red wine, juicing, chlorophyll, insect protein, and more!

Does Red Wine Block Cholesterol?Nutrition myths were crumbling left and right this week. In this podcast, I look at the research on garcinia cambogia for weight loss. (Short answer: Save your Money)  In another show, I looked into rumors that drinking red wine blocks cholesterol in red meat. As it turns out, no red meat was involved in this research!

While I was at it, I tackled the urban legend that chlorophyll strengthens your blood. And speaking of blood, this episode discusses whether juicing is a healthy habit or a blood sugar bomb.

It wasn’t all myth-busting though. It’s a fact that certain nutrients can help protect your eyes as you age. Here are the best food picks for  healthy eyes.  And for those who are easily distracted in the kitchen, here’s reassuring news about the effect of overcooking on protein. (No promises on taste or texture, though.)

Finally, here’s one of the most, ah, interesting stories I’ve reported on this year:  a movement to shift the world toward insects as a safe and sustainable source of protein. No crickets were harmed in the writing of this story. At least, not by me.

Part of the answer depends on how much you sweat (or, if you’re a lady, how much you perspire)! Here’s a quick tip on how to calculate your sweat rate.

While we’re (sort of) on the topic of salt, here’s what you need to know about  iodine deficiency and how to avoid it. And from the “one more thing to worry about?” category, this week’s podcast explains what ORAC values mean for your health.

Staying on Track when Eating Out

This article is also available as a podcast. Click to listen:

In an effort to help people make healthier choices when eating out, many restaurants are now required to publish calorie counts and other nutrition information right on their menus. Usually, the laws only apply to restaurants with more than one location, such as fast food and chain restaurants.

Even if they aren’t required to put them on the menu, most chain restaurants and some others publish nutrition information on their websites.

Many Would Rather Not Know

I’ve heard from a lot of people who say that having nutrition information on the menus takes some of the fun out of eating out. And frankly, the restaurants aren’t that crazy about the idea either because they know that many restaurant goers would be horrified to find out just how many calories their favorite dishes contain.

Having spent some time in professional kitchens I can tell you that sparing calories is not the first priority of most chefs. They want their food to taste good and it’s a whole lot easier to turn out tasty dishes when no one’s measuring out the butter, if you know what I mean.

Sidestepping the issue of whether it’s fair (or even constitutional) to force restaurants to put calorie counts on the menus, I have to say that, from a public health perspective, it has brought about some positive changes. Being forced to disclose the calorie counts on menus has motivated many chains to add healthier, lower-calorie choices to their menus.

And, even if people say they would rather not know how many calories are in that plate of fettuccini Alfredo or that side of onion rings, having the number right there on the menu makes it a bit harder to remain in denial—and often results in people making healthier choices.

Take Menu Information with a Grain of Salt

Now, I have to warn you to take the nutrition information you see on menus with a grain of salt. When preparing a sample dish for analysis, ingredients are precisely measured. But dishes are not going to be as carefully executed in the heat of battle as they were for nutrition analysis. Unless it’s a highly automated fast-food restaurant where every squirt of special sauce is premeasured, you’re likely to get portions that are significantly larger, cooked in more oil or butter, and served with more salt, sauce, or salad dressing than the version that was analyzed.

Whether or not nutrition information is provided on the menu, and regardless of how reliable it may be, it is possible to find the healthier dishes by reading menu descriptions carefully and learning to watch for certain code words.

The words “creamy,” “crispy,” and “smothered,” for example, are all code for “slathered in fat.” I’d also be on guard against items described as “rich,” “thick,” or anything topped with several kinds of cheese. Instead of dishes that get their flavor from heavy sauces, look for the simpler preparations. Words like “steamed,” “seared,” “poached,” or “grilled” signal a lighter, leaner style of cooking.

Ordering Strategies

In addition, there are a couple of ordering strategies that can help you get a healthier meal without feeling like you’re left nibbling nothing but garnishes.

  1. Request that salads and other dishes be lightly dressed or sauced. Sauces and dressings are where all the calories hang out and most kitchens apply them with a heavy hand. Asking for things to be lightly sauced or dressed usually results in a lower-calorie plate, not to mention a better-balanced and tastier dish.
  2. Inquire about half portions. Except for those frou-frou nouvelle cuisine restaurants where everything is the size of an ice cube, most restaurant portions are two or three times what any normal person should be eating at a meal. Even if they are not listed on the menu, many kitchens will serve half-portions upon request.
  3. Ask for the veggie of the day. Although they may not be listed on the menu, most restaurants will have one or two fresh vegetables that they are serving on any given day. These can often be requested in place of potato or French fries.

Finally, you’ll have an easier time finding healthy menu options if you pick your restaurant carefully. As much as I love Indian food, most Indian restaurant meals are very high in fat and calories, for example. Sushi restaurants, on the other hand, are a great place to get a light, nutritious meal. Pub grub is usually heavy on fried foods, whereas a grill will have more healthy choices. Diners tend to specialize in things covered with cheese, gravy, or syrup; a bistro usually has entrée salads and other lighter options.

You can also take advantage of the “small plate” trend by seeking out Spanish or Middle Eastern restaurants that serve tapas or mezze. Instead of ordering an entrée, you make a meal out of small “tasting” portions of three or four different dishes. You can turn any restaurant into a small plate restaurant, by the way, by ordering two or three appetizers as your meal. Just remember, when selecting appetizers and small plates, to apply all of the guidelines we just talked about. Avoid the crispy chicken smothered with three cheeses, and go for the grilled shrimp on a bed of spinach!
