What does fattening mean?
Fattening describes something that causes weight gain, most often food that is high in calories or fat. A plate of chips, a slice of cheesecake, or a creamy sauce might all be called fattening, and the adjective is a staple of everyday conversation about diet and health. Though usually said of food, it can extend to habits or periods — a 'fattening' holiday, for instance, is one spent overindulging. The word carries a mildly negative connotation today, reflecting modern concerns about obesity and nutrition, yet it originated in a far more practical world: for centuries, fattening was primarily something done deliberately to livestock before slaughter. That agricultural sense survives alongside the dietary one, giving the word an interesting double life. Simple and familiar, 'fattening' remains one of the most immediately understood ways to flag calorie-dense indulgence.
Causing an increase in body fat; (of food) rich in calories or fat and likely to lead to weight gain.
