Benefits for Fat Loss and Muscle Building
Immediately following your workout, the carbs you eat cause an insulin spike. Using ALA, you can channel more of the glucose to the muscle cells instead of the fat cells gaining more lean muscle mass without a concurrent gain in body fat.
Of particular interest to the bodybuilder is the fact that ALA enables the muscles to increase the amount of glucose that they absorb from the blood stream by increasing the number of glut -4 transporters on the out-side of the myocites (muscle-cells) by almost 50%. By forcing the glucose and nutrients into both the MUSCLE-cells and the fat-cells, one can use ALA as a nutrient-partitioning agent.
The net result is an increased muscle-gain over the long run with a smaller fat-gain. To give you a quantitative idea, if a person gains 10lbs muscle and 10lbs fat in a bulking cycle without ALA. He/she is likely to gain around 14lbs muscle and 6 lbs fat if he/she would have taken ALA.
