Those who want to lose weight successfully, at least at the beginning, can not avoid keeping a food log. Because most people cannot estimate how many calories they actually consume. "I do not know why I am overweight," they say, "because I don't eat much!"
Little snacks, sweets and soft drinks slip on into the menu. Even a glass of iced tea or a banana -- no matter how healthy it may seem -- contain calories and influence the energy balance. The calculation is quite simple: Whoever burns more energy than he or she eats, loses weight and vice versa. How many calories a person burns per day depends on age, current weight, metabolism and, of course, exercise. Exercise is not only about the calories consumed, but also the activation and production of the enzymes needed to burn fat.

That is why regular exercise - at least every other day for 30 minutes - is so important.
