Meat sweats

Meat sweats is a colloquial term referring to the idea that eating a meat-heavy meal will cause individuals to perspire profusely. While anecdotally it is a popular term, the scientific basis is weak.

Scientific basis
The theory is that digesting protein burns more calories than either carbohydrates or fat, leading to a raised body temperature called diet-induced thermogenesis.

While scientific studies have shown evidence of elevated body temperature from diets higher in protein exists, some researchers dispute whether it is enough to cause people to sweat.

Origin
The phrase was popularized in a 2001 episode of “Friends,” when the character Joey Tribbiani wiped his forehead and said, “Here come the meat sweats” after eating an entire turkey during Thanksgiving dinner.

In popular culture
Despite the thin scientific evidence, the concept is often used in marketing. In June 2022, Arby’s, the fast food chain, together with the deodorant brand Old Spice,  introduced a “Meat Sweat Defense” kit, consisting of a custom roast beef sweatsuit, gym towel, sweatband and a can of deodorant spray.
