1. What you would prefer is your problem not his.
2. Drugs aside. its quite a myth that bigger deficits are harmful for people that is this obese … everything points to the opposite.
Here is etc one of my favorite case studies on fatloss,
therapeutic fast of 382 days’ duration
To quote Holly from Joes Forum “An obese man weight 456lbs (207kg) underwent a period of fasting lasting 382 days, consuming nothing but a supplements such as vitamins and electrolytes. During this time, he went from 456lbs to 180lbs, and maintained his weight following the fast, with no ill health effects. This casts a shadow over the extent to which metabolic adaptation is experienced during a deficit, as well as debunking the myth of “starvation mode”.”
Tell me about starvation mode and the need of cutting on 3800 kcals, when this man fasted for a year with no ill effects and kept the weight off.
