I'm at my leanest on a majority fat diet but I still use tablespoon measurements and make sure it has a purpose. I'll eat juicy meat without hesitation. Starches and vegetables use 1 tbsp fat via cooking or topping. Cream, chocolate, nuts, and cheese are desserts that I use when I'm too low on kcal (in 0.5-1.0oz doses). I never do oil coffee or anything like that.
Fat is my favorite fuel but in practice is about 5x as dense as protein and carbohydrate foods so handle with care!
