>Maybe body builders lose lean body mass when they fast
Well, highly fit people certainly lose lean body mass when they fast, which you're probably not (even if you're fairly fit)
And bodybuilders DON'T lose fat when they fast because they take supraphysiological doses of hormones (steroids) that prevent the body losing muscle - and usually eat protein throughout their fast too. So not a good example.
Their whole argument was around body builders not losing fat when fasting, so if you're right, this is just irrelevant. No one expects people to lose fat when they're not caloric restricted.
