I dont believe that "your body despise having muscles" and that your muscles turn into those fibers into adipose tissue. Adipose tissue is your "fat storage", where glycerol and fatty acids is layered as Triacylglycerol (TG) in the absorbtive state, the state of digestion of substrate after eating a meal.
You have a window of opportunity to strengthen your proteinsynthesis which is something like 2-3 hrs (max!) after finished work, to drink something that would increase your synthesis. Alot think you have to drink some sort of big protein-power-drink powder in order to activate this synthesis, but actually chocolatemilk is on of the best liquids you can drink after working out, and to those of you (and I know you're alot!) who's shaking their heads in rage I will explain why:
After you're done with your work your body will have used energy mostly glycose, but depending on the exercise type and duration. Your body is then interested in filling up these more or less empty storages, in which your liver does a huge amount of work. Becuase weightlifting is an anaerobic kind of exercise your body have to use the glycose stored (as glycogen) in the muscles to activate contraction.
Milk contains proteins, this we all know. It also contains a decent amount of fat which is needed for the essential proteinsynthesis in the muscles. The adipose tissue are responsible for storing fat which can be split into amino acids and glycerol. Because you have been exercising the adipose tissue (white adipocyte cells) have been transforming TG into amino acids and glycerol for the body to use as energy source, this is floating in your blood steam now in which your muscles will be obtaining by diffusion (although some say that fat and amino acids needs a protein to bind in order to cross the cell membrane I will write simple diffusion for the sake of simplicity).
Now chocolate milk also contains sugar, which by intake increases the concentration of insulin in your blood and this is a very important feature because the insulin inhibits the breakdown of substrates and stimulates the storaging process.
These two things combined stimulates your bodys proteinsynthesis along with restoring the glycose concentration in your bloodsteam in order for you to live (5 mmol/l!!!). It's mostly the same thing that protein-powder-shakes do but a much more simplified and often cheaper way to stimulate musclebuilding.
