If you are doing proper exercise and taking normal diet but still not losing weight as more it can be then you must check your daily activities. The study by the Harvard team showed tiny changes in diet and lifestyle can make a big impact. The study focuses on human lifestyle like foods, activity, sleep habits etc.
Taking less calories in food is not a good diet. But a proper selection of food is very important. Foods that added most to weight included daily consumption of potatoes, sugar-sweetened beverages, unprocessed red meats and processed meats. Fruits, vegetables, whole grains and nuts, if you increase their intake, you had relative weight loss.
Sleep also played a role. People in the study who got between six and eight hours of sleep were less likely to gain weight over the study period. But people who got less than six hours or more than eight hours tended to gain weight.
And when people increased their physical activity, they tended to gain less weight during the study period. The studies also focused on watching TV. The more you will watch TV the more you will get away of physical activities. So watch less TV and get involve in physical work.
