I just found a right pair of opinionated idiots on Youtube. (Also the most foul-mouthed simpletons ever to shout at a TV set!)
On the Tube just enter 'Biceps and Banter'. You will be informed beyond all doubt that the low carb diet is all (Rowlocks!)
They ripped up the BBC documentary and confirmed that they are both world experts; Legends in their own minds that is!
You will have to watch your Blood Pressure though, because they are insulting towards us. Especially when they preach to everyone about calorie deficit
Apparently all you have to do to get the right nutrition is eat less fat, make funny drinks with whey powder, snack on hi carb energy bars, and half-kill yourself in the gym, at regular intervals!
