What does fatless mean?
'Fatless' is an adjective describing something that contains little or no fat. It is formed by attaching the common English suffix '-less', meaning 'without', to the word 'fat', in exactly the same way that 'hopeless' means 'without hope'. The word belongs chiefly to the kitchen and the clinic: cookbooks use it for sponges and cakes made without butter or oil, while dietary writing applies it to meals, dressings, and snacks promoted for their low fat content. Because cutting fat changes texture and flavour, 'fatless' often carries an implicit promise or challenge — a fatless sponge must rely on whisked eggs for its lift, and a fatless sauce must find body elsewhere. Though 'fat-free' is now the more frequent term on packaging, especially in American English, 'fatless' remains current in British cookery writing and adds a slightly more literary note to the same idea. Its antonyms include 'fatty', 'rich', and 'creamy'.

Where does fatless come from?
The word is transparently formed from 'fat', inherited from Old English 'fætt', combined with the suffix '-less', from Old English 'lēas' meaning 'free from' or 'devoid of'. It arose through ordinary English compounding rather than borrowing, so it has no Latin or Greek cognates; instead it shares its root with native derivations such as 'fatty', 'fatness', and 'fatten'. Such formations became especially productive in the vocabulary of food science and dietetics of the modern era.
