Here's the video of his talk given at the recent Low Carb conference held in Boca Raton.
His idea is that the whole concept of CICO needs a rethink because energy itself has no mass. The example given is that if you have a kilogram of nearly boiling water on a scale, it will weigh 1 kg. When it cools (no evaporation in this thought experiment!) then it still weighs 1kg. Yet the calories of the water have certainly reduced as the heat energy dissipated.
You don't need to watch the whole thing. Watching from the 18:30 mark to around 38:00 covers the meat of it, I think. Ultimately you get to the equation that shows we get 4 calories per gram for carbs and protein and 11 calories per gram for fat. When you invert that to look at weight, you see that you get 0.25 grams/kcal for carbs/protein and 0.11 grams/kcal for fat.
He theorizes that you lose weight on low carb simply because you are consuming less mass. He also shows the difference in mass for a LCHF vs LFHC meal and it works out to about 1/3 pound per day in mass difference.
Anyway, I thought it was interesting and worth sharing. It certainly demands a different perspective from the 1st Law of Thermodynamics purists.
