I understand, have you tried adding more healthy oils and nuts/nut butters (peanut butter, almond butter, etc.) to your diet? They are pretty easy ways to add a lot of calories without carbs for people who aren't able to eat a lot of calories otherwise. 1g of olive oil will give you around 9kcal, when I used to track all my daily intake it was around 100+kcal for a tablespoon of olive oil. Peanut/other nuts butter provide a little less calories per gram but add protein to the mix.
