Do you know who the top level athletes with Type 1 are who are following this diet? I have met many over the past 9 years and none has ever mentioned it in their speeches or in conversation. My goal here is not to judge, but to understand. I cannot imagine how a low carb diet could fuel intensive several hour training day after day. A game of flag football, sure, but you might want to be careful when he is in a tournament and playing several games in a day for a few days in a row.
