Metabolic research is expensive, and so most published studies have had very few participants. When it comes to weight gain, he says, the issue is the same as it has always been: People are eating more calories than they are burning.
He added, “I don’t think you can make any new clinical statements” for an individual. Samuel Klein, who was not involved in the study and is director of the Center for Human Nutrition at the Washington University School of Medicine in St. “We will have to revise some of our ideas,” she added.īut the findings’ implications for public health, diet and nutrition are limited for the moment because the study gives “a 30,000-foot view of energy metabolism,” said Dr. In an interview, she said she was “blown away” by its findings. Rozalyn Anderson, a professor of medicine at the University of Wisconsin-Madison, who studies aging, wrote a perspective accompanying the paper. “It will be in textbooks,” predicted Leanne Redman, an energy balance physiologist at Pennington Biomedical Research Institute in Baton Rouge, La., who also called it “a pivotal paper.” The findings from the research are likely to reshape the science of human physiology and could also have implications for some medical practices, like determining appropriate drug doses for children and older people. They also found that there are no real differences between the metabolic rates of men and women after controlling for other factors.
Using data from nearly 6,500 people, ranging in age from 8 days to 95 years, researchers discovered that there are four distinct periods of life, as far as metabolism goes. Menopause only makes things worse, slowing women’s metabolisms even more.Īll wrong, according to a paper published Thursday in Science. That’s why they have a harder time controlling their weight. Everyone knows conventional wisdom about metabolism: People put pounds on year after year from their 20s onward because their metabolisms slow down, especially around middle age.
