I agree, it seems like a lot of the rules have changed. I think I'll stick to what I know.
as for the coffee tablets, its something to do with the 'chemicals' in the raw coffee bean which stops you using all your glucose stores from food, so you're not using the caffeine. so, i think(!), by taking the tablet with your carbiest meal, it stops your body absorbing all the glucose in the carbs, which, as we know, is what turns to fat - this doesn't mean you can cheat! If i thought i could eat fresh bread and take those tablets instead of doing the diet....!
