Thanks so much, Janet. This summary really helps me understand the Protein Leverage Hypothesis. It sort of crystallized for me how my own, highly individual, plan works that way, too.

When we consider how carbs are NOT a required nutrient, and how fat is highly satiating (suggesting we don't need it in quantity,) that only leaves protein, which we know is a vital nutrient: the most important in terms of rebuilding the entire body. With keto/low carb, fat is what we burn for energy. Then it's easy to see the difference between what the body needs in terms of fuel: and building blocks.
