Within reason! If you’re following the Olumia Life Nutritional Ratio, you should be getting plenty of food already. Remember, you can eat second helpings at a meal provided you maintain the ratio. The amount of protein and fiber from fruits/vegetables ought to keep you satisfied until your next meal.
That said, sometimes you need a little boost. When that happens, you can go to Snacks section in your Olumia Life app (in the Nutrition+ section) to find physician-recommended snacks that are perfect for a little pick-me-up.
