Hi, I'm new to the site, and can't find any discussions on the recent episode of Horizon related to high carb v's low carb eating. I would post a link but i'm new so can't do that yet. It's called "Fat v's Sugar" and is still available on iplayer. The episode shows a pair of twins over a month, one tries a high fat diet, one tries a high sugar diet. Obviously, it was just a tiny experiment involving one set of twins and so therefore generalisations cannot really be drawn scientifically, but I still found it really thought provoking. Especially the effects of the low carb diet, which caused a significantly negative impact on the chaps sensitivity to insulin (putting him in the pre-diabetic category) and caused him to lose significant muscle mass! I have been doing some form of low carb WOE on and off since 2006, not to lose weight necessarily, as I didn't need to back then, but because I read a book by Gary Taubes and truly believed that carbs were the devil (health wise). Anyway, just wondering what others thought if indeed they watched it?
