This is incredibly important for helping your salad feel even more filling to keep you satisfied longer. Claudia T. Felty, PhD, RD (@drclaudiatfelty on Instagram), noted in an Instagram post, "You need the fat to digest the fat soluble vitamins in the salad. So eating all those plain carrots doesn't do you a whole lot of good if you're hoping to absorb all that vitamin A."
Just be mindful of not going overboard with avocado, nuts, seeds, and dressing. Healthy fats tend to be higher in calories, so measure out your toppings.
