Does exercise affect the metabolism?

The following year, a Follow-up study concluded Physical activity has helped some runners avoid gaining weight. If they moved or exercised for about eighty minutes almost every day, they regained fewer kilos than if they exercised on a few occasions. However, his physical activity did not stimulate his metabolism while at rest. Those who exercised, in fact, showed the greatest reduction in terms of resting metabolic rate.

Perplexed, Hall recently began to reconsider the studies of The biggest loser In light of a new concept about the way human metabolism works. This idea started with An impressive study from 2012 shows very active hunters In Tanzania they burn the same relative amount of calories per day as the rest of us, even though they move around a lot.

Scientists involved in this research hypothesized that tribal peoples’ bodies should automatically compensate for some of the calories they burned while foraging by reducing other physiological activities, such as growth. (Tribesians tended to be short.) In this way, the researchers believe that hunters’ bodies can keep the total number of calories they burn each day in check, no matter how many kilometers they search for tubers and prey. Scientists called this idea Limited Total Energy Expenditure Theory.

Recognizing this research, Hall began to see potential similarities in the findings The biggest loser. So for the new analysis, he went back to reviewing his group’s data for clues about whether the runners’ metabolism behaved, in practice, like that of hunting and gathering. He’s found clues in resting metabolic rates. The figure fell early in the filming The biggest loserHall noted that when they cut back on how much they ate, their bodies understandably reduced the calories they burned to avoid starvation.

However, in later years, when the contestants went back to eating as they had done before, their metabolism remained depressed, because, as Hall concluded (and that was the key), most of them were still exercising. Paradoxically, he wrote in the new analysis, it appears that frequent physical activity has instructed your body to keep your resting metabolic rate low, so that your total daily energy expenditure can be limited.

“It’s still just a hypothesis, but it seems to be what we’re observing” in the incoming data The biggest loser It’s an “example of the finite energy model,” Hall said.

So what can he rethink in history The biggest loser For the rest of us, if we hope to keep our weight in check? The first and most important thing, Hall said, is that it suggests that sudden, massive weight loss in general will rebound, as this strategy appears to send your resting metabolic rate to speed up your metabolic rate more than expected, given the small body size. People. He noted that when people lose weight gradually in weight-loss experiences, their metabolic changes tend to be less severe.
