Fat Burning During Exercise Varies Widely Between Individuals
hubie writes:
The best heart rate for burning fat differs for each individual and often does not align with the "fat burning zone" on commercial exercise machines, Icahn School of Medicine at Mount Sinai researchers report.
Instead, the researchers said, clinical exercise testing-a diagnostic procedure to measure a person's physiological response to exercise-may be a more useful tool to help individuals achieve intended fat loss goals. The study, which used a machine learning-based modeling approach, was published online today in Nutrition, Metabolism and Cardiovascular Disease.
"People with a goal of weight or fat loss may be interested in exercising at the intensity which allows for the maximal rate of fat burning. Most commercial exercise machines offer a 'fat-burning zone' option, depending upon age, sex, and heart rate," says lead author Hannah Kittrell, MS, RD, CDN, a PhD candidate at Icahn Mount Sinai in the Augmented Intelligence in Medicine and Science laboratory. "However, the typically recommended fat-burning zone has not been validated, thus individuals may be exercising at intensities that are not aligned with their personalized weight loss goals."
