I don't know what exactly will work for you, but Peat doesn't usually recommend extremes of either high fat or low fat for most people - mixed meals seems to be good for a lot of people.I think I need to just bite the bullet and have fats (saturated, in particular) because this is the only way I can reasonably fill up. I don't think really low fat is good for my metabolism / libido. Yesterday had 5000 calories almost all from carbs, and even with that much food, my libido was nearly non-existent. I think I do better on high fats. My libido was highest when I was on Keto / Very low carb back in the day, interestingly enough.
