Doc here. I'm not surprised that an adult male carrying 33.4% body fat dropped weight on an 1,800 calorie diet. Nor am I surprised that his cholesterol stayed down. If you've every seen a patient on total parenteral nutrition or g-tube feeds, they all move toward a normal BMI and then get scrawny. The switch over to skinny is due to muscle atrophy from disuse. If they survive and return to a normal activity level, they typically regain the muscle mass.
The take-away: don't eat too much.
Quiz:
1) what three food groups did he cut out of his diet?
2) What is the normal range of BMI for an adult male?
3) Fat is transported in the blood in various kinds of packets. HDL and LDL are proteins that label the outsides of certain packets. If HDL goes up during weight loss, where do you think those packets are coming from? Where do you think LDL packets are going to? If Professor Haub's weight equilibrates with his new 2100 calorie diet, what do you expect will happen to his HDL and LDL?
