He said that sugar was a terrible thing, which we have all heard before, but he said something along the lines of three teaspoons of ‘added’ sugar per day resulted in an 11 fold increase in risk of type II diabetes regardless of any other factor INCLUDING the amount of exercise you do…

To me that implies something else bad about sugar besides high GI – because high GI can be a good thing if you have been exercising.

Can’t find anything about this particular study online though.

Something to do with insulin resistance perhaps if the added sugar is an everyday occurrence?

Well perhaps but exercise increases insulin sensitivity so decreases resistance.. everything I’ve read about exercise suggests that it counteracts the risks of Type II.

However finding something high GI at work to eat post-training/commute is hard without sugar. White bread or toast is about it.
