Prevent Weight Gain: Exercising is not enough

Exercise on its own, without following a healthy diet is not enough to help people lose or even just maintain their weight.

But according to the research in US it has been found that the obesity is caused by a lack of physical activity.

When it comes to figuring out the causes of obesity, what we really need to look at is what people are eating,

Previous research, for example, has linked a greater risk of obesity with the consumption of high-calorie food and sweetened beverages,

In the new study, the researchers found that the amount of time people spent exercising per week did not seem to play a role in how well those people controlled their weight.

At the beginning of the study, the researchers asked all of the study participants to wear tracking devices for one week to measure how much time they spent exercising. The researchers used the data to see whether the people in the study met the U.S. Surgeon General’s physical activity guidelines, which recommend that people exercise at a moderate pace for at least 2 and a half hours per week.

 

The researchers also measured each participant’s weight, height and body fat three times: at the start of the study, one year later and two years later.

When the study began, the participants in Ghana weighed the least, on average, and those from the U.S. weighed the most, according to the study. The average weight of both the men and women in Ghana was 139 lbs. (63 kilograms), while the average weight of American men was 206 lbs. (93 kg) and of American women, 202 lbs. (92 kg).

At the end of the two-year study period, the researchers found that some of the people who met the physical activity guidelines at the beginning of the study were more likely to gain weight than those who did not meet the guidelines.

It’s not entirely clear why exercise may not help people lose weight, or may sometimes even be linked to weight gain. One possible explanation is that because exercise tends to increase appetite, it may simply cause people to eat more than they otherwise would.
