Why You Shouldn’t Exercise to Lose Weight

Many of us are lacing up our sneakers and starting (or restarting) exercise regimens (练身计划) in hopes of shedding unwanted pounds. Unquestionably, aiming to be more active is good. But if the main reason is to lose weight, your New Year’s resolution could very well     1    .

For starters, exercise — at least the kind most of us do — is     2     ineffective for weight loss. Take walking, for example. A 150-pound person who walks briskly for 30 minutes will burn, on average, around 140 calories. That’s equal to one can of soda — not exactly a great return on your investment of time and effort. It’s much easier just to skip the soda.

Studies     3     show that doing moderate-intensity aerobic exercise such as walking for 30 minutes a day, five days a week — the amount recommended for good health — typically produces little or no weight loss by itself.

When moderate exercise is added to diet, the results are equally not     4    . Pooling data from six trials, researchers found that a combination of diet and exercise generated no greater weight loss than diet alone after six months.

In studies where exercise has produced     5     weight loss, participants burned at least 400 to 500 calories per session on five or more days a week. To achieve that, sessions need to go well beyond what most of us are willing or able to do. And even if we manage to exert that much effort, our bodies often     6     by boosting appetite and dialing down metabolism, effects that over time limit how many pounds we shed.

Perhaps the biggest problem with exercising to drop pounds is that it turns physical activity into     7    . How many times have you heard someone say (or said yourself) “I’ll need to do extra exercise” after eating too much during the holidays or at a celebratory dinner?

The point is that we’re more likely to     8     exercise positively and actually do it when we focus on our well-being rather than our weight. The incentive may be an improved mood or less stress. Others may find that exercise makes them feel physically and mentally stronger.

Of course, the benefits of physical activity     9     well beyond these. It’s been shown to reduce the risk of multiple diseases. It can also improve sleep and boost energy.

By all means, striving to exercise regularly in the new year is perhaps the most important thing you can do for your health. But to improve the odds of success, focus on how movement helps you feel better physically and emotionally — and forget about how it moves the     10     on the scale.
