Yes, provided you don’t overdo them! It is a common knowledge that the fats coming from nuts and such natural butters made out of peanuts, almonds, cashews, hazelnuts and macadamia nuts are high in omega 3 which can actually help you to use fat for energy. These are delicious sources of fat and can definitely help you achieve your goals, when you have them in moderation. Nut butters must be natural, without additives. Read the ingredients on the label. There should be no other ingredients than nuts and salt.
