when pros are pushing high carb diets, then they are playing around with insulin, if someone tries that without insulin he s gonna look like shit.
I don't know if insulin makes you not look like shit on high carbs. It's not like it helps keep you dryer and reduces the chance of gaining fat/makes you lose fat despite "high" carbs. Insulin does not make it easier to get in shape... you have to do more cardio, use more burners, eat less calories overall.
I remember when "blockhead" used to say pros would get fat if they didn't use insulin with "high carb" intakes. Makes zero sense to me.
Insulin or not, if someone is eating a relatively high protein diet, which all pros do pretty much, the diet will naturally be low-moderate carbs, especially close to the show.
