What you will read many of us have known for a long time. Experience tells us that exercise alone cannot make us thin, that is why all those infomercials we see that claim their exercise equipment will do wonders for your body always come with a diet plan.
Do not go out that ask for a refund of your gym membership. There are some benefits to exercising for its own sake, to keep you fit and feeling your best but not to make you thin.
“In general, exercise by itself is pretty useless for weight loss,” says Eric Ravussin, a professor at the Pennington Biomedical Research Centre, in Baton Rouge, La., and an expert on weight loss. It’s especially useless because people often end up consuming more calories when they exercise.
