Interesting that alcohol can be seen as acutely protein-sparing in the sense that it halts oxidation of all 3 macronutrients. Not that it would be a good basis for binge drinking, but good information to know.
Question: You posted a link to Matt Stone's post about low-carb diets and lowered metabolic rate. I am wondering if metabolism is more affected by glycogen levels themselves or by the mere act of eating enough carbs to prevent the drop in thyroxine output.
1) What if I ate 150g of carbs prior to a completely glycogen-depleting training session? Would my metabolism still drop due to low glycogen? Or is it the fact that I ate enough carbs for the day that would prevent the drop? In other words, what if I did the training session first, followed by consumption of 150g of carbs? Now, those carbs would go toward glycogen resynthesis.
2) Does the makeup of the carb matter? What if out of 120g of carbs I ate in a day, 50-75g of it was fructose? Now hepatic glycogen may be full for a while, but that doesn't leave much for muscle glycogen. Which glycogen tank is more intimately linked to the CHO-T3 axis?
Creatine can yield incredible benefits when trying to cut body fat because it allows you to maintain strength , even when glucose levels are extremely low. There have been numerous types of creatine to hit the shelves in the recent years. You may have heard of kre-alkalyn creatine, creatine phosphate, creatine citrate, creatine esters, and more. Each of these claims to help you build lean muscle and increase your strength in the gym. Everyone responds differently to these various forms, but in my experience... the most enduring type has been regular creatine monohydrate. I have personally used the micronized version from Biochem . This creatine comes in an ultra-fine consistency that will have minimal stress on the kidneys and cause the least amount of potential bloating. Don't be afraid to take creatine monohydrate when dieting, it will not make you like your "holding water" but it will help you maintain your strength and keep you from looking flat and stringy while trying to lose body fat.
