educing fat too much makes foods lose their taste. Fat helps taste and keeps the heat in cooked foods. Lowering the fat in the diet to a range between 25 and 30 percent of calories makes sense since fat has 9 Calories per gram while carbohydrate and protein have only 4 Calories per gram. The idea that low fat foods do not help with weight loss is the result of the food industry adding back sugar to make up for the taste lost by reducing fat.
