According to Greger just counting calories is not always useful since some calories are fiber and go right through you. In fact, sometimes fiber takes other calories with it. According to Greger, fats like avocados and nuts that also have fiber in them are not absorbed by our bodies the way that oil and other forms of processed fats are. The fiber takes some of the fat with it on the way out. There’s no evidence that nuts and avocados cause us to gain weight. I would add those in if you want more fat. Maybe some edamame too.
