Why avocado has more calories
Most fruits get their calories mainly from carbohydrates. Avocado is different because it is rich in fat, which gives it a creamy texture and higher energy density.
How to portion avocado
Use a few slices when avocado is a topping, a quarter avocado for a lighter add-on, half an avocado for toast or bowls, and a whole avocado when it is the main ingredient in a shared dish like guacamole.
How to balance avocado calories
Pair avocado with high-fiber vegetables, lean protein, eggs, beans, or grains. This creates a meal that feels complete instead of relying on avocado alone.
