I believe one of the alternatives someone tried to milk on GOMAD was a jar of PB a day. But since calories are easier to drink than to eat, have you tried drinking a can of coconut milk a day?What can I do to gain weight? I've been eating about 2500 calories per day (60% fat, 30% protein, 10% carbs) since going 99% paleo. I cook everything in coconut oil and douse my veggies in melted butter. I realize that I can gain weight eating carbs, but I'm worried my acne flaring up.
