| Interesting. I was always under the impression that using ratios of carbs that high was more of an athlete's diet than a weight loss diet.
How long does liver and muscle glycogen last? My understanding is that muscular glycogen stores are relatively low (compared to those in the gut, for example) and that muscular catabolism was a result of reliance on slow-to-free triglyceride stores in fat cells. If glycogen stores in the liver and muscle were sufficient to meet that requirement, I don't see why the body would need to liberate proteins -
Unless you're saying that the other 50% - 60% is liberated from adipose tissue AND muscular protein, which I suppose would make sense. However, in a fat loss scenario, wouldn't you want to ensure the body's reliance upon stored fatty acids (limiting carbohydrate intake to about 30% - 40%)? |
