The truth about the phenomenon of 'flesh sweating'

In the US, some people believe that after eating a lot of meat, the body will sweat profusely, a phenomenon known as "meat sweat," but experts deny this.

The idea that eating a lot of meat can make the body sweat has existed for decades. Scientists are unsure exactly when this notion originated, but it became more popular around the 2000s.

According to Dr. Donald Layman of the University of Illinois Urbana-Champaign, there is some evidence that high-protein diets increase body temperature. However, most research on this issue is small and was conducted decades ago.

In a landmark study published in 2002, scientists from Arizona State University asked 10 young women to eat either high-protein or high-carbohydrate foods for a day and measured their body temperature and other indicators.

They found that women who ate protein experienced a higher body temperature compared to the group who ate carbohydrate-rich foods. Other studies have also shown a similar phenomenon in men.

Marie-Pierre St-Onge, associate professor of nutritional medicine at Vagelos College of Medicine, explains that when you eat protein, your body has to use more energy to digest it. This inadvertently releases some heat. This is because protein is more difficult to break down than carbs or fats.

The McMaster Study of Nutrition, Exercise and Health at McMaster University in Hamilton, Ontario, also shows that the process of digesting protein consumes more energy. The body uses ingested protein to create new protein. This stage also generates heat in the body.

Dr. Layman stated that most of the energy from protein-rich meals is used quickly by the body. Therefore, people burn three to four times more calories after eating meat compared to eating fat or carbohydrates. In a small study published in 1999, scientists found that eight women on a high-protein diet burned 87 more calories a day than when they ate a high-fat diet.

Although protein warms the body quickly, scientists don't believe that eating a lot of meat will cause people to sweat more. According to Dr. Layman, there have been no official reports of the phenomenon of "meat sweating" to date.

Protein increases body temperature more than other nutrients, but the relative increase is quite small. The temperature of women in the 2002 study was only about 0.2 to 0.3 degrees Celsius higher than average after following a high-protein diet.

Associate Professor St-Onge said that some people may feel warmer after eating meat, but that doesn't mean they will sweat profusely.
