The truth about the phenomenon of 'meat sweating'

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

The idea that eating a lot of meat can make you sweat has been around for decades. Scientists aren’t sure when the idea first came about, but it became more popular around the 2000s.

Some evidence suggests that high-protein diets increase body temperature, but most studies on the subject are small and were conducted decades ago, says Donald Layman, Ph.D., of the University of Illinois Urbana-Champaign.

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 had higher body temperatures than those who ate carbohydrate-rich foods. Other studies have shown the same phenomenon in men.

When you eat protein, your body uses more energy to digest it, which in turn releases heat, says Marie-Pierre St-Onge, MD, associate professor of nutritional medicine at the University of California, San Diego. That's because protein is harder to break down than carbs or fat.

The McMaster Nutrition, Exercise and Health Research at McMaster University in Hamilton, Ontario, also found that protein digestion requires more energy. The body uses ingested protein to create new protein. During this phase, the body also generates heat.

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

Although protein warms the body quickly, scientists do not believe that eating more meat will cause people to sweat more. According to Dr. Layman, there have been no official reports of "meat sweats" to date.

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

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