We have a great lineup of questions this week. We cover topics ranging from lean mass changes in fasting; how glycogen, the storage form of carbohydrates, works in the body; various nuances and applications of the ketogenic diet for hypertrophy, and long-term longitudinal use; and target blood glucose fluctuations after a meal! Free Fatty Friday (FFF) is a rapid-fire Q and A session with Geoffrey Woo, where he answers all your questions with a 5-minute cap on all answers. Feel free to send your questions here: podcast@hvmn.com Q1: 02:49 Very nice critique of the IF study. Any comments on the Lean Mass changes? Does it really make any sense? Q2: 11:01 I have been wondering about carbs in liver. It is in the form of glycogen. Do we have digestive enzymes that can let us even access this? Is it available as a nutrient? When is a carb not a carb? When you can't use it. Q3: 17:21 What causes insulin resistance? Why would the body resist something that is useful and why do some have no resistance and others do? I know the answer seems to be genetics and poor health but what is the mechanistic aspect of the resistance? Q4: 22:25 For a ketone ester, are they the same ketones our body produces naturally or what? What happens if you chug the whole bottle? Q5: 28:59 What's your view with alternate day fasting and hypertrophy training on feeding days? Q6: 34:45 How much should blood glucose fluctuate after a meal? Q7: 38:45 Can keto help build muscle? Is keto diet recommended for longterm use? Twitter: @geoffreywoo Email: podcast@hvmn.com Sign up for the latest FFF-specific updates here: geoffreywoo.com/signup Join the Official H.V.M.N.
