How much is metabolism fast is a question of genes predispositions but it is changing according to build-up. As I said the muscle takes care of main portion of energy consumption (in active state). Just for information the count of body cells (fat or muscle) is independent of weight increase or decrease. For example professional 30 years old body-builder in perfect condition has the same number of body cells like before he started body-building. Muscular cells have reserve of glucose and glycogen and by their glycolysis cells create molecules of ATP, immediate source of energy for muscle contraction and so on. Muscle cells of the body-builder are very big and ready for expenditure of great amount of energy. These cells have much higher consumption of energy than the cells of person who has been 5 days on tough diet and his cells have atrophied and got smaller about 15%. These cells need much less glycogen. It is same case like the fuel consumption of Hummer and little fiat. This is the main barrier for weight loss and fat loss. Because if we reduce our input of energy under the level our body needs then fat loss is not only one effect but it causes atrophy of muscle cells. And atrophy of muscle cells decrease the level of needed energy.

So if your energy consumption for keeping weight before some foolish diet was 12 000 Kj, it could be 8 000 Kj after the diet. It means to drop one big meal from your day menu for keeping your weight.

This is not anything good because we managed to weight loss but we have to eat fewer food than before to keep our weight. And in the case we want to lose more weight by some low-calorie diet we can’t eat almost anything. If we are lucky and we manage even this than we have to eat only vegetable, yogurts and tiny portion of every meal to keep our weight and level 6000Kj of energy consumption. In this damned situation man takes part in some grilling and beer drinking for 2 days and third day he’s got 5lb in addition. If your 2 day energy consumption was 30 000Kj so before diet 6 000Kj would be over the consumption level for weight keeping. But now would be over 18 000Kj and this caused the 5lb in addition.
