Exercise Counters Obesity Genes
When it comes to obesity, don’t allow your genes to determine your destiny. Previous studies have shown that 1 in 6 people have a particular gene variant that boosts their risk of obesity by 70 percent. But exercise appears to counter that effect significantly. Researchers reviewed 60 studies, involving over 200,000 people. They report that an hour or more of weekly exercise reduced the effect of the obesity-related gene variant on a person’s body mass index (BMI, a ratio of weight to height used to estimate how close someone is to a healthy weight) by 33 percent. That means that exercise will help counter weight gain—even if you’re genetically wired for obesity.
