In a new genetic study, women in their 70’s who were physically active maintained a healthy weight despite genetic predisposition to obesity. This is the first study of its kind to show that women after menopause can combat the effects of genetics.

Researchers examined data from 8206 postmenopausal women. They created a genetic risk score for obesity based on 95 single-nucleotide polymorphisms associated with body mass index (BMI).
Participants were classified as being sedentary or having a low, moderate, or high activity level, where a moderate activity level was about 150 minutes of physical activity a week.

The study revealed that despite a high genetic propensity for obesity, women who exercised for 150 minutes per week were able to maintain a healthy weight.
