- Wheat contains anti-nutrients and fiber. both will slow down the absorption and assimilation of carbs/glucose and cause a much lesser hormonal response (ie, non anabolic response) from the body. carbs end up sitting in the gut, not getting fully absorbed, and then passing through the body (giving your bowel movements a lot more volume).
for muscle building you want carbs that are very easy and rapidly digested, and that generate a greater hormonal response from the body.
less 'shit' (literally) and more muscle.
- Fruit again contains fiber as well as its main carb source being fructose. Fructose is the only carb source that CANNOT be used/stored as muscle glycogen (it can't build muscle or energize muscle), it can only be stored in the liver or eventually as fat.
you want carbs that are easily stored as muscle glycogen. it is through these carbs that amino acids, water, nutrients, creatine, etc.. are able to get into muscle cells and build muscle.
with those two carb sources as your main sources, your missing out on a lot of the anabolic nature of carbs. which I will argue that carbs are more anabolic then protein (as protein does not generate near the hormonal response that carbs do). protein is broken down into amino acids, and these amino acids are usually uptaken into muscle cells when you consume carbs, get an insulin response, and the insulin drives the carb/glucose into the muscle cell as glycogen, and the amino acids then are able to 'hitch a ride' into the cell as well.
note: fiber is important. get only what you need though, as in abundance it can be a real nuisance
