So, for the uninformed peanut gallery, beagle3 is just plain wrong. Probably not intentionally, he's likely also fooling himself. But you locked him in a room and measured his food for him and really only fed him 1200kcals per day, even at a fairly sedentary level of exercise, a 220lb man would lose a lot of fat mass over several weeks. And no beagle3, human bodies tend to be very greedy with calories and do a good job absorbing them regardless of what you smell.

What likely happened is that reducing carbs reduced beagle3's appetite and he ate less. Unless...

...unless beagle3 has a magic body that has never once been seen in any controlled experiment. But he probably does, since every dieter who has problems believes they have a special body that science can't explain. So they buy a book and a program from someone who tells them what they want to hear. And if their guru is on their game they sell very very expensive supplements.

Because its a well known scientific fact that the first law of thermodynamics applies to everything in the universe except a disgruntled dieter.
