Nothing. Do you know if he ever went past Induction/OWL and got to maintenance, so you know what he was eating by the time he finished? He may have been eating nothing but eggs, meat and tuna and the same veggies over and over because he didn't have a wife/gf who used some imagination to fix meals. He may have limited the types of foods he ate so much he is bored stiff with Atkins. I missed this program and if any of those who saw it know what his meal plans looked like, they would be better able to address this. He probably just misses all the high-carb stuff that made him so heavy in the first place.
