Meat sweats is a colloquial term referring to the idea that eating a meat-heavy meal will cause individuals to perspire profusely.^[1] Its scientific basis is unfounded.^[2][1]

One theory is that digesting protein burns more calories than either carbohydrates or fat, leading to a raised body temperature called diet-induced thermogenesis.^[3][4]

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.^[2]

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.^[2]

Despite the thin scientific evidence, the concept has been 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.^[2]
