Working out targeting specific groups of muscles enlarges them..but to do that serious weightlifters consume MORE calories from the protein & carbs food groups..not less..you cannot build muscle mass whilst on reduced calories..its impossible. Sadly when 'wasting' its often the major body organs such as the heart which suffer first..the body needs calories and they have to come from somewhere...its too complicated to go into in detail but to metabolise 'fat' you need a combination of protein & carbs...our bodies are amazing..so why abuse them (guilty of that myself sadly as a generous helping hand with the portions!!)

If you stop exercising & put on weight the muscle remains as muscle but loses its tone & bulk.ie flabiness....but does not go away as it does once wasted.
