I'm no genius, but I'd definitely think reducing protein intake would be wise if sedentary. Depending on your lean mass and weight, you'd probably need half what you would if active. I mean, half of all macros! If you burn 3500 calories walking around, and only 1700 calories sitting in a chair, then eating less makes a whole lot of sense.
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.
