GDAs are popular in the fitness industry because athletes are very reliant on effective insulin timing and glycogen uptake.  GDA decreases the amount of insulin secreted by the body when consuming carbohydrate rich meals by acting as insulin and shuttling glucose into muscle cells. The act of shuttling glycogen into muscle cells is desirable, but when we solely rely on insulin we run the risk of moving glucose into fat cells. By decreasing the body’s own insulin production, insulin receptors can be optimized and a decrease in fat gains can be realized. Similarly the GDAs, by mimicking insulins anabolic property, can shuttle glucose into the muscle resulting in lean muscle gain.

A good quality GDA will allow you to eat more carbs to help promote lean muscle gain, aid performance and limit the amount of these carbs being eventually stored as body fat. By taking GDA with your pre-workout meal, it will enhance the uptake of these carbs into glycogen within the muscle which then can be used as fuel when training. Glycogen full muscles when training will lead to greater muscle connection and longer pumps when training.
