I am having some trouble getting the calories I need in my diet. I need to restrict my carbs, so they can't come from that. Fat has the most calories per gram.

So my question is, what kinds of foods can you eat that have calories coming from fat and none coming from carbs?

The trouble is you want the right fat and many higher fat, low carb foods are full of saturated fat.

Other foods with better fats include nuts and avocados - which will contribute carbs. There's also olive oil - and oil on a salad increases nutrient uptake, and oily fish such as tuna, great fats on those.

Whatever you do, dont start loading your arteries up with horrible fats from deli meats, fatty meat, too much cheese or too many eggs. All foods are fine in moderation but you have to get your fat balance, and particularly your Omega 3/6/9 balance right, which you wont do if you eat too many animal based fats.
