You might want to get a jar of extra virgin coconut oil, and just take a little before a meal, particularly a meal that's low in fat by default (lean meats and veggies).

Start by eating a teaspoon straight from the jar before a meal, if you tolerate that well, gradually work your way up to an amount that seems right in terms of fat content of the entire meal. Don't be afraid of the fat! These are short-chain fatty acids anyway and will be burned off for fuel, not stored.
