Funnily enough, on the subject of sugar... I went batshit mental yesterday just to try and get one day with some weight gain (over 270g of sugar, over 500g of carbs)... lost half a kg. lol
I believe I've read that blog post before. I was hoping for a link to a study that you claims has already proven something, not a link to Anthony Colpo's site :/
He discusses a ward study at length. I appreciate the guy is a dick, but I'm not sure why you're so quick to dismiss the information.
Oh, and as I posted above, we know that certain diets work better for certain people. There's no question of that, however, I'm talking from a macro standpoint, and we also know that on the whole there's very little in the way of (at least rigorously performed) studies that show a significant advantage for one diet vs another (again, matching intake and accounting for TEF).
Thing is, this thread is a great example. There are people here who have great results on high carb, and people here who have great results on low carb.
Edit - Just looking at that 5,000kcal challenge. His protein intake is nearly double on the low carb diet vs the high carb diet. Pretty significant difference there, makes it hard to really draw any conclusions at all from what happened.
