Golden Rule 2: Fat is also your friend
I know this may seem counterintuitive, but eating fat will help make you skinny. Up to 40% of your calories should come from fat. Like all food groups, the type of fat is also important. 1/3 of your fat should come from monounsaturated fats (olive oil, nuts and nut butter, avocado), 1/3 of your fat should come from polyunsaturated fats (some nuts, fish, fish oil, flax seeds), and 1/3 of your fat you come from saturated fats (animal fats—egg, meats, butter—and coconut oil). Don’t get too caught up in the percentages. Instead, focus on including more mono- and polyunsaturated fats, which tend to be lacking in our diets. That means adding olive oils, avocados, and fish oil to a diet high in protein and vegetables.
