And another experience, here! I went very high-fat to get my system convinced it was safe to use it for fuel. It worked! I lost about ten pounds, nice and slowly. Months later, I reduced the fat and increased the protein, and have continued to reshape my body. Now that I've had it, I know what it feels like to be satisfied - and for me, that's protein. And a lot of it. Very often 1000 calories of protein a day. Fat is next, by caloric density, and then greens and sweet potatoes, avocados, eggs and the rest.
But, yes, I lost weight and gained muscle when I dialed back the fat and increased protein.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
