Exercise really does not lose weight, this is the "life-saving" mechanism evolved by human beings

The Hadza tribe of more than 1,300 people living in Tanzania is believed to be the last hunter-gatherer tribe in Africa

 To understand the specific energy expenditure of the Hadza, Herman Pontzer , now an associate professor of evolutionary anthropology at Duke University,and colleagues conducted a 2012 study

After adjusting the calculations for body weight, they found that the average total daily energy expenditure (TEE) of the Hadza was very similar to that of men and women in the average country, regardless of gender, and that high levels of physical activity did not increase their TEE

After exercise, other expenditures of the body will spontaneously decrease After exercise, other expenditures of the body will spontaneously decrease

Pontzer believes that the Hadza have changed the way energy is consumed

Pontzer believes that the Hadza have changed the way energy is consumed

Data from other teams backs up this idea: After weeks of training for a half-marathon, daily sedentary women experienced little or no increase in daily energy expenditure compared to when they first started training

Reasonable evolutionary results would not allow strenuous exercise to have a significant effect on human TEE.

Can you lose weight as a couch potato as long as you eat less? Can you lose weight as a couch potato as long as you eat less?

People who are concerned about weight change may interpret this study from another angle: since weight gain or loss depends on the difference between the energy in food and the energy expended by the body, and the TEE is basically constant - even if you never exercise A couch potato, who is also likely to consume almost as much energy each day, won't gain weight just from not exercising

Pontzer's research on the Hadza confirms the same: Many Hadzas in their 70s and 80s are still in good health and rarely suffer from diabetes or heart disease, thanks to constant exercise

Pontzer also proposed a conjecture about the mechanism by which the body spontaneously balances TEE—“The Hadza hunter-gatherer did not increase daily calorie burn, but changed the way they consumed calories”, especially in some unseen tasks on, such as inflammation and stress responses

This study unexpectedly shows that exercise can lead to weight loss is not absolute, but exercise reduces the number of calories burned at rest in obese patients, rounding up to no weight loss
