As you have had an eating disorder, which I presume he knows about, no, it is not. It is not healthy for you to start that kind of thing without a dietician's help. You don't say your height but unless you are very short (under 5ft 1) , you are not fat in the least. I think he is a control freak and his 'game' could be dangerous to your future health. I'll be honest-- probabilitiy is he'll have shuffled off in a few years and if you get caught up in unneccesary weight loss, you could relapse...so you'd be left with a potentially life threatening condition due to his selfish stupidity, while he walks off, whistling.
