Doug McGuff presents the biochemistry behind high-intensity strength training and the paleo diet, including how the body stores and burns fat. It is a roughly hour-and-a-half full-length lecture.
HN recommends it as the theory behind Body by Science, explaining metabolism and why brief intense training works.

Julian Shapiro, YCombinator alum, has a very nice guide to building muscle.[0] The gateway drug to the HIT tradition, which began with genius Arthur Jones and Nautilus in the early 1970s, is this video presentation by Doug McGuff[1], author of Body by Science[2]. Whether you follow a HIT protocol or not, you should be familiar with the theory covered in Body by Science. Doug covers the definition of fitness and health (which is unusual right there for a fitness book!), the confounding effects of genetics, fat metabolism, and much, much more. The High Intensity Business podcast has all the leading figures in exercise research as guests, with a rich back catalog and very detailed links in the show notes.[3] And if you plan to do this for the rest of your life, give your future joints a break by not destroying them in your youth.[4][5] [0] [LINK] [1] this video [2] [LINK] [3] [LINK] [4] [LINK] [5] [LINK]
The true scientific one is called Body by Science [1]. If you have 100 minutes, invest watching this [2] from God himself (Doug McGuff M.D.). P.S. The next The 21 Convention will be in January 2015 [3]. [1] [LINK] [2] this video [3] [LINK]
Actually from what I understood about intermittent fasting it is way better than simply eating less. I'm not a doctor but the mechanisms by which the body burns fat is that it has to send the proper signaling at a cellular level. If you listen to the video here starting at 1h03: this video Though the video is to understand how energy is used and stored for workout reasons it explains a bit the mechanism whereby the body decides to store fat or convert it to phosphates for semi-immediate use. I'm convinced that intermittent fasting turns off the body fat storage mechanism and turns on the burn fat mechanism. Unfortunately if you only eat less you never send the signals to your body that it needs to stop storing fat. An intermittent fast is therefore way better than just eating less. For me intermittent fasting means not eating breakfast and eating around 12h30. I've lost 14 pounds this way and I'm finding it really easy to skip a meal now where I couldn't do it without having a headache before.
>I'd love to see a star[v]ing obese person. Most obese people are suffering from something called "internal starvation", which is a byproduct of insulin resistance. The mini-lecture on fat biochemistry is here[0]. [0] this video [1] [LINK]
>Sorry but in terms of obesity and weight loss, it's really not more complex. No, it is extremely complex. "Calories in < Calories out" isn't even stating the principle you think it is. You want to make a statement about fat balance depending on calorie deficit, independent of what type of food you eat, and even that is completely wrong. Different foods take completely different paths through the human digestive system (e.g., fructose vs. glucose) and thus have completely different effects independent of their "calorie" count. Most people on a calorie deficit are not also exercising, and their weight loss is 25% muscle loss, which is a disaster for their future health. Peter Attia makes a careful statement about "calories in/calories out" in the first few minutes of this lecture: [LINK] Doug McGuff covers med school biochemistry and metabolism in the last part of this presentation, and mentions "internal starvation" where obese people crave food at regular intervals, but the food goes directly into fat tissue. this video Hey, if it is just calories in < calories out, why is Bill Gates so much richer than me? All he did was spend less than he earned, right?
