Fats from nuts and natural butters made out of peanuts, almonds, cashews, hazelnuts and macadamia nuts are high in omega-3s which can actually help you to use fat for energy. These are delicious sources of fat and can boost your fitness and weight loss goals, as long as you don’t have too much of them. You can make nut butters at home easily. Just make sure that they are natural and you don’t add anything other than salt to them. Add roasted nuts to a food processor or blender and blend until a creamy butter forms. This can take up to 10 or more minutes. Avoid adding water or liquid sweeteners.
