Synonym discussion
Sense: adjective/1
All four terms describe products with less fat than a standard version, but they differ in degree and regulation. 'Low-fat' means the product meets a fixed fat threshold (e.g., 3 g per 100 g for solids). 'Fat-free' or 'nonfat' is stricter — less than 0.5 g of fat per serving, often with more additives to improve texture. 'Reduced-fat' is a relative claim: the product has at least 25 % less fat than the regular version, but the absolute amount could still be high (e.g., reduced-fat peanut butter still has plenty of fat). 'Light' or 'lite' is the broadest term — it can mean reduced fat, sugar, salt, or calories, or sometimes just a lighter colour or texture. On a yogurt label, 'low-fat' (1 % fat) is a precise nutritional grade; 'light' might only mean fewer calories without specifying how.
Etymology
A compound adjective formed from 'low' (meaning 'small in amount or degree', from Old Norse lágr) and 'fat' (from Old English fǣtt, meaning 'fattened'). The term first appeared in English in the early 20th century as dietary guidelines began recommending reduced fat consumption, and gained widespread use with the rise of packaged 'diet' foods in the 1970s and 1980s.
