What do people think of this? A dialogue I was having with someone on another board. My post (directly below) was in response to his assertion that complex carbs could be better in terms of fat gain than simple carbs.

I’ve never known anyone to benefit in terms of body composition by switching away from fast-acting carbs and keeping calories the same."
From swole: "Excess glycogen is stored as fat. If your body does not utilize the dex ingested PWO immediately by either (1) replenishing your glycogen stores, or (2) as energy, it is stored as fat by raising your triglycerides. Excess sugar (simple sugar) is directly related to increased triglycerides, the absolute worse, most unhealthy kind of fat.
As you probably know, high triglycerides is a leading cause of coronary heart disease.
Let?s say someone can store the maximum in their body, or 350 grams of glycogen. They then do a workout and expend 50 grams of glycogen. Then, PWO, they drink a dex/protein drink that includes 100 grams of dex. The excess 50 grams (350-50+100=400. 400-350 = 50 grams excess) can?t be stored; because your muscles are full.
What I am saying is that if that excess 50 grams is not expended, it will to turn to fat. Simple sugar = insulin spike. Insulin spike not used as glycogen = increased triglycerides.
Now that situation would probably not happen to you, but I can see it happening to someone who does not work out intensely. Think of the person who has that drink, then sits down with a meal that has even more simple carbs. So instead of getting an excess 50 grams, they might add another 100 in simple carbs on top of that.
Hopefully, this would not happen to most people on this board, but I can see it happening to someone who is overweight, or someone who has poor dietary habits, or someone who does not work out intensely."
Not sure that I agree with his reasoning.
