Exercise is a controlled stress to the body. The idea is to systematically fatigue the systems, so that as the tissue regenerates during the recovery cycle it will become stronger and more enduring. Alcohol and caffeine can delay the recovery process, resulting in poor tissue regeneration. This can cause an accumulated deconditioning affect where fat metabolism and the ability to sustain protein is inhibited. So if you are interested in developing greater tissue efficiency and to see an actual change in the appearance of your body composition, limit the use of these compounds.
