Fueling for the athlete with Type 2 Diabetes.
I am a 52 year old male athlete who competes recreationally in mid distance to Ultra running events. I am starting to train for a full Ironman in 1 year. In light of the December 2010 joint position statement by The American College of Sports Medicine and the American Diabetes Association entitled; Exercise and Type 2 Diabetes, how should an athlete with Type 2 fuel prior to an event or particularly long hard workout. The study states; "Insulin-stimulated BG uptake into skeletal muscle predominates at rest and is impaired in type 2 diabetes, while muscular contractions stimulate BG transport via a separate additive mechanism not impaired by insulin resistance or type 2 diabetes.". Based on this concept I see no issue with me being able to effectively fuel intra-workout but how should an athlete fuel pre-event.....the big pre-race pasta dinner clearly not being an option. What are the mechanisms that allow for a sufficient uptake of glycogen into the muscles while in an insulin resistant state? Thanks for your insight.
Methionine Restriction and Selenium Supplementation
Bob and Peter, what do you guys think about the role that methionine restriction should play in the DR lever of a nutrition plan? How about supplementing with selenium to get some of those benefits? Here's the recent article that obviously prompted my question: "Selenium supplementation inhibits IGF-1 signaling and confers methionine restriction-like healthspan benefits to mice," found here: https://elifesciences.org/articles/62483 Dane New Orleans
