Probably the clearest explanation of why all three macronutrients can make us fat in a calorie surplus.
"Let’s assume someone is eating at exactly maintenance calories. Neither gaining nor losing fat. Here’s what happens with excess calories. Assume that all three conditions represent identical increases in caloric intake, just from each of the different macros. Here’s what happens mechanistically and why all three still make you fat:
Excess dietary fat is directly stored as fat
Excess dietary carbs increase carb oxidation, impairing fat oxidation; more of your daily fat intake is stored as fat
Excess dietary protein increases protein oxidation, impairing fat oxidation; more of your daily fat intake is stored as fat
Got it? All three situations make you fat, just through different mechanisms. Fat is directly stored and carbs and protein cause you to store the fat you’re eating by decreasing fat oxidation.
And I’d note again, since someone will invariably misread this that that doesn’t mean that a low-carb and/or low-protein diet is, therefore, superior for fat loss. I’m not saying that and don’t think that I am. Because in such a situation, while you may be burning more fat, you’re also eating more dietary fat. So net fat balance can be unchanged despite the dicking around with macronutrient content. It still comes down to the deficit."---Lyle Mcdonald
