4. Nutrition scientists can calculate the amount of weight gain that would be associated with a given increase in calories. In one study, 16 non-obese adults, aged 25 to 36 years, were fed 1000 calories per day in excess of the calories needed to maintain a stable body weight. The subjects maintained this diet for 8 weeks, thus consuming a total of 56,000 calories extra. According to theory, 3500 extra calories will translate to weight gain of 1 pound. Therefore,...
