Hey Justin, two questions.
1. Some coaches believe in keeping carbs out of breakfast even in the offseason to keep insulin at bay, while some believe in keeping em in, and that it's very important to preserve muscle. What's your take?
2. Do you think it's possible to increase insulin sensitivity by eating the same amount (carbs/calorie-wise) but just shifting em around throughout the day, so you go longer without having carbs?
1: I've been seeing this more and more lately. I don't see any real benefit to keeping insulin at bay to perserve muscle. Insulin is arguably THE best thing there is at preserving muscle...it's incredibly anti-catabolic and it dramatically increases amino acid uptake.
I can see keeping insulin levels down in the morning for its affect as a CNS depressant (big carb meals can make you sleepy), but I don't see any benefits to muscle preservation by doing that.
2: No. I don't believe insulin sensitivity adjusts at any physiological level on an hourly basis...it takes a much longer time frame for the tissues to become desensitized or increase their sensitivity to insulin.
