Why Exercise Alone Isn’t Enough To Prevent Weight Gain

The new study examined more than 1,900 people in the U.S., Ghana, South Africa, Jamaica and the Seychelles (an island nation in the Indian Ocean). 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.
