When it comes to describing a food item that is low in fat, there are several synonyms to use instead of saying "no fat". These synonyms not only help to add variety to your language but also make your description sound more interesting and appealing. Some of the synonyms for "no fat" include "fat-free", "low-fat", "lean", "skinny", "slim", "light", "reduced-fat", and "non-fat". It is important to note that while these terms may have subtly different meanings, they all essentially describe foods that contain minimal or no fat content. Therefore, it is up to you to choose the synonym that best suits your intended message.
