All of us agree that we need to do more exercise and eat controlled quantities of the right foods in order to lose weight. But physical activity might not be as advantageous as we had thought.
Significant weight loss it is often matched with obese people increasing their physical activity , but this often declines after a few months.
Even when they try increase the amount of exercise they’re doing everyday, the extra weight no longer seems to shift.
The researchers claim that there is a remarkable difference in calories burned from sedentary people to moderate exercises, however; there is no such difference in calories burned with people who participated in some more intense exercises.
Interestingly, this study might help to explain a curiosity that is noticed by biologists studying how hunter-gatherers’ bodies expend energy, as they lead fantastically active lives walking long distances and doing hard physical work.
Herman Pontzer, coauthor of the study published in Current Biology, said _and I quote_: “Despite these high activity levels, we [find] that they [have] similar daily energy expenditures to people living more sedentary, modernized lifestyles in the United States and Europe. That was a real surprise, and it got me thinking about the link between activity and energy expenditure.”
To put that under examination, Pontzer and his team measured the daily energy expenditure of more than 300 people (men and women) from five countries, for a full week. The collected data showed how there was a slight increase in energy expenditure and calories burning when the subjects of the experiment first started on an activity regime.
On average, during a moderate exercise people burn around 200 calories.But when they increased the amount and level of activities, they had nothing to show , as the body adapts to the extra work.
Pontzer said _and I quote _: “Exercise is really important for your health. That’s the first thing I mention to anyone asking about the implications of this work for exercise. There is tons of evidence that exercise is important for keeping our bodies and minds healthy, and this work does nothing to change that message. What our work adds is that we also need to focus on diet, particularly when it comes to managing our weight and preventing or reversing unhealthy weight gain.”
The researchers say that we need to stop assuming that more physical activity means more calories burned, as this relationship is not that simple.
