I'm totally aware of Lyle's article that each lb of muscle burns 6 calories a day.
Say you lose 20 lbs of LBM (which you will if you keep up a severe protein deficit on RFL.) That slows your fat burning metabolism down by 12.5 lbs of fat annually. That's 50 pounds over the next four years.
Most bad information out there says gain muscle first to increase your metabolism.
Lyle's argument is do the diet first, then build muscle because it takes forever to gain muscle. But his argument isn't "lose muscle first, then the fat"

Thank you Lyle. This website is a game changer once you understand the mechanisms behind fat loss/muscle gain.
