It is generally thought that by drinking skimmed milk you can get whole milk’s benefits – Vitamin D, calcium and protein amongst others – without the fat and calories.
By reducing the fat, the skimmed milk is certainly lower in calories, but the authors of the study -David Ludwig, of Boston’s Children Hospital, and Dr. Walter Willett, of the Harvard School of Public Health – believe lower calorie beverages do not necessarily mean lower calorie intake.
Obesity means having too much body fat. It is not the same as being overweight, which means weighing too much. A person may be overweight from extra muscle, bone, or water, as well as from having too much fat.
Both terms mean that a person’s weight is higher than what is thought to be healthy for his or her height.
Taking in more calories than you burn can lead to obesity because the body stores unused calories as fat. Obesity can be caused by:
- Eating more food than your body can use
- Drinking too much alcohol
- Not getting enough exercise
Many obese people who lose large amounts of weight and gain it back think it is their fault. They blame themselves for not having the willpower to keep the weight off. Many people regain more weight than they lost.
Today, we know that biology is a big reason why some people cannot keep the weight off.
