most of my calories come from fat instead of carbs. I get just a little bit more protein than necessary (I assume for my size i need about 70g and I eat about 100g) to promote muscle growth and size as I workout. I dunno if it works that way but I know I wont get bigger by eating the same so... I eat more. If eggs are your main protein/fat source, I would suggest trying beef back fat. The soft/moist kind, not the dry suet kind of fat. I find its very easy to consume a lot and is very satisfying. However the more fat you add the fewer carbs you should consume, otherwise the whole insulin/triglycerides issue will come up.
I know AV promotes butter a lot and I've never had raw butter but most people here seem to be mostly against dairy.
I know we're in the ZC section so plant fats should be out, they don't do well anyways. Within two weeks they made me ill and I simply couldn't get them down without gagging.
Beef fat is my largest food intake source and the only time I've had issues with digestion is when I simply eat too much and it makes my stool soft and oily with undigested pieces. I find chewing more can help that however.
Try seafood too, I find raw salmon/oysters/etc. to digest extremely well and are loaded with beneficial nutrients. It'll knock the fruit out your butt!
