Something clicked in my mind just a few minutes ago and I had to rush to the computer to get this idea out for discussion. According to Alessi, meltdown training works by creating a lot of lactic acid which then stimulates growth hormone. Growth hormone then does its thing and we all become huge and ripped at the same time. I don’t want to discuss the growth hormone at all. I want to talk about lactic acid. Lactic acid is a product of anaerobic glyolysis. So to produce lactic acid, you need glycogen. On low carb (like the T-Dawg as Alessi recommends) or no carb (like Fat Fast), most people will be severely glycogen limited or have almost none at all. So where is the lactic acid coming from? Without stored glycogen, one has to rely on the glycerol portion of stored triglycerides converting to 3-phosphoglyceraldehyde and then to pyruvate which can then go throught the Cori cycle to create glucose and eventually go through anaerobic glycolysis to produce lactic acid. Also, many amino acids are glucogenic (primarily alanine and other BCAA’s) and can be deaminated and converted to pryruvate, malate or oxaloacetate which can also be converted to glucose. So to get our glucose so that we can get our lactic acid, we have to use both fat and protein for energy metabolism. According to my readings, it seems as if both sources contribute quite a bit to the gluconeogenic pool. Anyway, it seems like a recipe for muscle loss. I know that I have read where Alessi’s staff members have recommended large doses of BCAA’s during exercise obviously to prevent muscle catabolism.
Anyway, my question is: why not do meltdown with an adequate carbohydrate intake? If the goal is to create a lot of lactic acid, you need a lot of glucose. If you keep carbs moderate to high, there will be plenty of stored glycogen for which to create a lot of lactic acid. I’m not saying that Meltdown cannot work with low/no carb diets, but it seems like it would be optimized to work with a diet higher in carbohydrates. With summer coming up, a lot of people may try Meltdown to lean up and I think that we need to figure out what kind of diet would be most optimal.
