Just a bit on the IF thing. Nothing terribly special about it. I was doing this years ago, and worked well for me the week before weigh in's, and I would have a very small lunch, usually protein based, then eat a normal meal minus the starches. after Practice (practice from 3:00-530). Although I don't recommend this, we restricted liquid intake about a day out of weigh in's, plus I've seen some of the others take diuretics It didn't even have a name back then, IF. Recently, some of the nutition guru's were playing around with the idea that restricted calories would lead to a longer fuller life, and came up with what they called intermittent fasting, and in the original lab protocols, they would eat one day, fast the next. Dr. Eades got a hold of this ideaand tried some tailoring to fit his needs, and came up with a cycle that wasn't as rough. Day 1 eat from 6 PM till 6:-00 pm the next, fast until 6:00 pm the next, and so on. Worked pretty well for him, and he wasn't even trying to dump weight. He and his cardiologist wife co-authored "Protein Power" which is somewhere in between Atkins and the Zone, low carb, and pretty much in line with what Ironman was suggesting.. You can see the topic come up a lot over on the crossfit forum. Just an idea. Bottom line though to the last bit of fat loss is physics, calories in, calories out, which will meanthat whatever macronutient combo you are using, will have to be cut back on. I can't explain your partners though, maybe their training is burning off the calories, and yes, I've lived in Hapan , some years ago, and know all about the needle houses in abundance over there.
