Like you were saying it's going to slow the carb absorption which will be counter productive for the skinny guy. Then the for the fatty the carbs would just make him fatter. So it's really just that they shouldn't be together.
I have enjoyed you post. I rarely respond because I agree with the informtation you present.
However, what you have presented is not backed up by any research, to my knowledge. If you have research to sustanciate this position, I would be interested in reading it.
I would be interested in Kevin providing me his reasoning for doing so as well as some data to back up that informtation.
Also, what would you define as a "fatty."
What the research shows is that providing workout is intense enough, both amino acids and glycogen are shuttled to the muscle cell. In the post workout period, very little if any fat is deposited from the post workout beverage. There is no delineation in any research that an individual, "skinny" or "fatty" would be different.
The hormone insulin is now touted as one of the most anaboiic hormones of the body. Manipulation of insulin in the post workout phase, put the brakes on catabolism.
Spiking insulin at other times of the day, does promote fat storage. As nutrition expert Jay Robb noted, "Insulin is a fat maker and glucaton (the counter to insulin) is a fat taker. However, this rule ONLY applies to eating periods that do not fall into the pre, workout or post workout periods.
If your premise were true, I suspect that a better resolution would be to limit the grams of simple carb to the drink rather than adding something like flaxseed oit to it.
Again, I would be interested in reviewing any research you or Kevin can provide on this subject.
