Does Exercise Make You Overeat?

No.

Some people respond to exercise by eating more. Others eat less. For many years, scientists thought that changes in hormones, spurred by exercise, dictated whether someone’s appetite would increase or drop after working out. But now new neuroscience is pointing to another likely cause. Exercise may change your desire to eat, two recent studies show, by altering how certain parts of your brain respond to the sight of food...

What all of this suggests, Dr. Hagobian of Cal-Poly says, is that “exercise has a definite impact on food reward regions. But that impact may depend” on who you are and what kind of exercise you do.

If who you are is "lack of self-control," then you gain weight.

“Four or five years ago, it really looked like appetite hormones” controlled what we eat, says Dr. Habogian, who conducted some of the first studies of exercise and the hormones. “But I’m more and more convinced that it’s the brain. Hormones don’t tell you to go eat. Your brain does. And if we can get the dose right, exercise might change that message.”

What is left of fat people's brains lacks self-control.

That is all.
