[fast5] Re: Fasting, exercise, and diabetes

Barnaby, what the article says (among other things) is that ATHLETE'S preferred fuel is glycogen and glucose. If you choose to go low carb and expect to be competitive as an athlete, then you should also expect your performance to go down. Fasting and low carb are great for burning fat, but "since sugar requires less oxygen than fat to be converted to energy, your needs for oxygen are greater to burn fat. This slows you down and tires you earlier." So, for competitive athletes, glucose is preferred.

The whole point of Fast-5 is that it's a method of reducing calories. Study after study shows that excessive calories, regardless of where they're from, lead to disease. Since fat has over twice the calories of carbs or protein, it stands to reason that it's easy to eat too much fat and gain weight, just by sheer volume of calories.

I think it's easy to get tunnel vision when talking about nutrition. As Heather has pointed out over and over, the Japanese eat a lot of white rice and yet have low body weight and relatively good health. Frankly, I tend to think that there are different metabolic types and high carb is good for some and high fat is good for others.

It appears he's not studied such low carbohydrate advocates like Barry Groves or Gary Taubes who advocate very low sugar in the diet to keep insulin levels low, along with moderate protein,yet don't have such fear of fat in the diet. After all, something is needed in the diet to fulfill calorie needs. It's like mixing apples with bananas when he combines "high calorie" with "high fat"...High Calories of WHAT?
