This is obviously someone who has never fasted and has way too much time on his hands.
Fasting has shown to increase metabolism 3-5% after refeeding (Shelton).
It's quite obvious that you can't eat like you did before or you will gain your weight back. You weigh much less than before so you should eat much less. I've dropped 40 lbs . Your stomach shrinks and it is more difficult to overeat. Also, the weight you do put back on will be less toxic, if you are careful about eating.
