Glycogen Loading is a Major Dietary Blunder

Glycogen loading landed on the exercise performance scene in the late 1930's and caught on. The idea that carbs were the sole source of fuel to power muscular contraction was around for 100 years but was gradually disproved.

What Dr. Ellis is saying is True, HOWEVER, the only fuel for ANAEROBIC exercise like sprinting, weight training, power lifting, then the fuel used is Glucose. However, from gluconeogenesis, 80% of stored glycogen is primarily from amino acids, a little from lactate and glycerol. So having small amounts of carbs isn't harmful (except gluten) and those extra carbs will be used up IF you weight train or workout. Hence the importance of workouts. I'd like to hear your thoughts on my post Dr. Ellis

@swedd2 You are quite wrong about this, again we don't want to care about glycogen. If you become adapted the primary source of fuel will be intramuscular triglycerides.For any exercise glucose at best provides 10-15% of fuel used and that is in one who eats carbs and would be well less in one who is fat-adapted.

Hi Dr Ellis, I am currently following a ketogenic diet whereby I load up on carbohydrates every 7 days in order to reload my muscles to support weight training. I am interested in trying your methods however may I ask one question? When my body fully adapts to fat and I no longer need carbs for high intensity exercise, will I still get a pump in the gym and have that full muscle look? I've noticed that without carbs I'm very flat. Thank you

@ThePaulyMichaelShow Yes, you will.

@Byebyecarbs Your right but what about Glycolysis from anaerobic exercise? Is intramuscular triglycerides used instead of glucose for doing lets say 3 sets of 10 for Bench Press. I don't think that study has ever been done. FYI, I follow a high fat, high protein low carb diet. I've always been interested in finding out how a low carb diet does when weight training. Also was I right about gluconeogenesis making 80% of the bodies glycogen? I heard the body can make 200-250 g of carbs a day.

I like videos like this. Most of the information contradicts the things I have been taught in A&P and nutrition courses that pressured everyone to eat about 70 percent carbs.

Dr. Stephen Phinney and Dr. Jeff Volek have done research on low carbohydrate dieting and endurance performance. They discovered that the original studies, which were interpreted to show that endurance performance was impaired when on low carbohydrate diets, were flawed because they were only run for a short period of time (1 to 2 weeks). Phinney and Volek found that if they allowed the athletes to stay on low carb for 6 weeks, their endurance performance returned to normal levels.
