Assuming you keep your diet in the range where you neither lose weight nor do you gain weight and keep it steady.
Also assuming that the only exercise you do is lift weights once or twice a week.
So in this situation, suppose you burn 1 lb of fat would that be converted into approximately 1 lb of muscle, i.e. 0.9 or 0.95 lbs of muscle? or would it be substantially less than 1 lb like around 0.1 or 0.2 lbs of muscle? Also what factors does body fat to muscle conversion depend on?
I have studied enough physics to know that 1 lb of fat would never produce 1 lb of muscle because if it did, the fat to muscle conversion process would have been 100% efficient and it did not waste any energy. If 1 lb fat did produce 1 lb of muscle then that would imply that you are eating more than you should.
