Interesting insulin-as-currency metaphor. The calories/weight rant is a bit misguided but the rest is good

“Your body just doesn’t give two flying f***s about calories. It’s not the common currency. Here’s the bottom line truth. ‘Calories’ is NOT a physiologic concept, just as ‘weight of food’ is not a physiologic concept” d30.co/2E0JEkq

How is it misguided? Calories are a think we made up by setting food on fire. Body don't care about calories.

It’s a measure of energy, so still makes sense as a basic way to analyze biochemistry equations This is like saying lift and drag aren’t the currency of flight because birds don’t think that way. Calories are bad as a currency for diet management, not as an analysis concept.

I think the point of Dr. Fung's rant was that calories aren't even all that useful for biochemistry. Hormone signals can completely change the context within which the reactions happen.

Basically odd to make the argument at all. Just “don’t use calories for thinking about diets, they’re for other purposes” would have sufficed. He makes it sound like alchemical elements like ether and phlogiston
