After hearing a description of my usual daily exercise schedule--a morning run or bike ride and an evening swim, sometimes with an hour of tennis in between-some people remark, "Wouldn't it be a lot easier to eat one less bagel a day and skip all that exercise?" My answer is, "Easier, yes, but not nearly as effective nor as much fun." Here's why exercise, not dieting, is best route to a leaner, lighter you.
Far better for your health and, your future to lose primarily fat is in the first place. The only way to do that is through exercise, which uses body fat as its main source of energy. You may not see that initial rapid (but false) weight loss, but what you lose will be what you want to lose--fat, not muscle or water. Your loss will be permanent, too. If it' s any consolation (安慰), studies have shown that in most cases, the faster people lose weight, the more likely they are to regain it. Slow loss, then, is the secret to lasting success.
If you want to lose weight faster than you can with just exercise, simply combine exercise with a reduced-calorie diet. Researchers at the University of California, Davis, showed that exercise could counter the metabolism-lowering effect of a low-calorie diet in many people, it also seems to curb the adverse caloric effect of aging on body metabolism. Whereas ordinarily your metabolism would slow down as you get older (which is one reason people get fatter in middle age even though they don't eat more), if you continue to exercise regularly, you may keep your youthful, metabolic rate by maintaining a muscular body instead of losing muscle and putting on pounds of fat.
What can be inferred from the passage?
A.The slower people lose weight, the less likely they are to achieve their goals.
B.People who are on diet merely lose muscle and water.
C.Regular exercises may reduce the chance of getting certain chronic diseases.
D.Physical activity use muscle tissue as its main source of energy.
