Much to the dismay of practically everyone, a new study published the New England Journal of Medicine debunks the myth that sex can burn a lot of calories.
Additionally, the research pushes back against the commonly held belief that snacking or skipping breakfast is bad and that school gym classes make a big difference in kids' weight. The journal says dogma and fallacies are taking away from real solutions to the country's weight problems.
David Allison of the University of Alabama at Birmingham and his co-authors investigated several myths stemming from studies conducted in the 1960s.
Claims that sex burns 100 to 300 calories are common, Allison told the Associated Press. But in fact, the researchers said that the energy output from an average six minutes of sex burned about 21 calories — the same as walking.
But other independent researchers said that while some valid points were made by the report's authors, many of them have financial ties to food, beverage and weight-loss product makers.
"It raises questions about what the purpose of this paper is" and whether it's meant to promote drugs, meal replacement products and bariatric surgery as solutions, said Marion Nestle, a New York University professor of nutrition and food studies.
