Of all the wonderful things exercise does for your body, more evidence suggests losing weight isn’t one of them.
Your daily activity level has almost no bearing on the number of calories you burn and burning more energy doesn’t protect against getting fat, Herman Pontzer writes in his new book, “Burn: New Research Blows the Lid Off How We Really Burn Calories, Lose Weight, and Stay Healthy.”
“Your brain is very, very, very good at matching how many calories you eat and how many calories you burn,” Pontzer, an associate professor of evolutionary anthropology at Duke University, told TODAY.
“The person who has a sedentary lifestyle and the person who has the active lifestyle will burn the same number of calories.”
What? We’ve all been taught the more you move, the more energy you burn, helping with weight loss. But that’s the wrong view of the human body’s flexible metabolic engine, Pontzer says.
A person starting that new Peloton program, for example, and exercising like crazy will burn more calories at first, but her body will adjust over the course of a couple months and begin to spend less energy on its many other tasks, like inflammation and stress reaction, until things are back to the way they were, he noted.
