Some caveats from this “enlightened” person’s perspective on why exercising is actually making people fatter.
“Could pushing people to exercise more actually be contributing to our obesity problem? In some respects, yes. Because exercise depletes not just the body’s muscles but the brain’s self-control “muscle” as well, many of us will feel greater entitlement to eat a bag of chips during that lazy time after we get back from the gym. This explains why exercise could make you heavier â?? or at least why even my wretched four hours of exercise a week aren’t eliminating all my fat. It’s likely that I am more sedentary during my nonexercise hours than I would be if I didn’t exercise with such Puritan fury. If I exercised less, I might feel like walking more instead of hopping into a cab; I might have enough energy to shop for food, cook and then clean instead of ordering a satisfyingly greasy burrito.”
And this one is awesome i thought, a little bit of the crazy conspiracy theorist goin on,
"Some of us can will ourselves to overcome our basic psychology, but most of us won’t be very successful. “The most powerful determinant of your dietary intake is your energy expenditure,” says Steven Gortmaker, who heads Harvard’s Prevention Research Center on Nutrition and Physical Activity. “If you’re more physically active, you’re going to get hungry and eat more.” Gortmaker, who has studied childhood obesity, is even suspicious of the playgrounds at fast-food restaurants. “Why would they build those?” he asks. “I know it sounds kind of like conspiracy theory, but you have to think, if a kid plays five minutes and burns 50 calories, he might then go inside and consume 500 calories or even 1,000.”
“In short, it’s what you eat, not how hard you try to work it off, that matters more in losing weight. You should exercise to improve your health, but be warned: fiery spurts of vigorous exercise could lead to weight gain. I love how exercise makes me feel, but tomorrow I might skip the VersaClimber â?? and skip the blueberry bar that is my usual postexercise reward.”
