debate among fitness experts was catching fire: Is exercise an effective
strategy for losing weight? Or is the effort ultimately a wash, triggering
hunger pangs that make you replace everything you burned and then
some? A decade ago no one thought to ask this. Too much food makes
you fat. Exercise burns calories. Ergo, exercise makes you less fat. Then
research began to find that not everyone who exercises loses weight.
Impossible as it may seem, some people actually gain a pound or two.
The problem: The range of individual responses to exercise is huge,
says veteran weight-loss researcher Timothy Church, M. D., Ph. D., a professor of preventive medicine at Pennington Biomedical Research Center in Baton Rouge, Louisiana. “We don’t understand all of it,” he says.
Fortunately, however, we understand enough to throw cold water on
four of today’s most insidious weight-loss myths.
