Don’t be an April Fool! Weight loss myths revealed.

Diets don’t work!

Exercise will make you gain weight!

This supplement will melt fat away while you sleep! 

Unfortunately, claims like these are not an April Fools joke. They are repeated so frequently that diets and exercise are avoided by many in favor of supplements to promote weight loss. Also unfortunately, they aren’t true. My Health & Fitness column in the Aiken Standard this week busts these common weight loss myths. Here is a bit more about each.

1. Diets don’t work! This is a common claim, usually to explain why most people who lose weight end up gaining it back. But diets do work. Almost every diet leads to weight loss in the short-term and some lead to  long-term weight loss. I have written about selecting the “best” diet and why the diet you pick isn’t the most important predictor of weight loss previously. And it is possible to lose weight and keep it off. But it is difficult, as this article explains so elegantly. Difficult, not impossible.

2. Exercise will make you gain weight! This is another popular myth about weight loss.  The good news is that exercise does work to promote weight loss. In fact, weight loss by exercise alone results in greater fat loss and preserves muscle compared to weight loss by diet. It’s true. But you probably shouldn’t try to lose weight by exercise alone. The best results will come from combining diet and exercise.

3. Melt fat away while you sleep by taking supplement X! This sounds great, which explains why Americans spend billions of dollars on dietary supplements each year. Unfortunately, most of these supplements have not been researched either adequately or at all to determine their effectiveness or safety, or they have been shown to be ineffective, as shown here. A conservative conclusion is that there are no supplements that have been shown to safely promote long-term weight loss.

If you were paid millions of dollars, you would lose weight too!

Jared Fogle has been a spokesperson for Subway restaurants for 15 years now. He has had a huge impact on Subway sales, largely because of his remarkable weight loss which was due, in part, to eating Subway sandwiches. (Of course, there is nothing magical about his “Subway diet.” The weight loss was due to the fact that he was eating far fewer calories!)

What is more remarkable than his initial weight loss is the fact that Jared kept the weight off for 15 years. He has had some serious motivation to do so. First, he has literally been paid millions of dollars to keep the weight off. Second, because his story is so widely known and because he is so recognizable, Jared is accountable to all of us. His weight regain would be noticed by many people, include some who have made him a role model.

Most of us won’t get paid to lose weight (or exercise or quit smoking), but we can find something to motivate us. And by telling people about our goals—or better yet, getting them involved with us—we are accountable to others. In this way we can benefit from the very same factors that have contributed to Jared’s success.

Simplifying calorie calculations for weight loss

Setting realistic weight loss goals and determining how many calories you should include in your diet requires estimating how many calories you eat and how many you burn each day. Sometimes these calculations can get a bit tedious.

The website Lifehacker just posted an article simplifying these calculations. Their approach is useful because a rough estimate of calories is enough to guide your eating and exercise habits. There really is no practical need for more precise calculations.

I would add one more number to know: 100. Walking or running one mile burns approximately 100 calories. The exact number depends on several factors including body weight and speed, but using 100 calories per mile makes calculations simple. For example, how many miles will you have to walk to burn off the the double mocha latte you had this morning?

By the way, Lifehacker regularly publishes articles on exercise and nutrition. I like the way they simplify sometimes complicated concepts and come up with practical solutions to common problems. From what I have seen, their interpretation and advice is consistent with the science, too.

Simple ways to start your New Year’s resolutions

New Year’s resolutions can be easy to make, but difficult to follow through with. This is due, in part, to the fact that some of the most common resolutions—losing weight, starting an exercise program, eating healthier, and quitting smoking—are some of the most difficult behaviors to change.

It is also because the process of making these changes can be complicated. If you want to lose weight you need to decide which diet you will follow, which may require buying specific foods or learning to prepare meals in a particular way. If you plan to eat out you will want to learn which foods fit with your diet. Maybe you will be counting calories or tracking points. That all takes time and practice, which might delay you from getting started.

Fortunately, there are some easy ways for you to jump-start your New Year’s resolutions. In my Health & Fitness column in the Aiken Standard this week I share a few simple steps you can take to get started. This can give you time to figure out the details and learn new skills to help you succeed in the long run.
