There are a few very important factors to consider. “For one, we lose muscle mass as we age—around 10 percent each decade after age 45,” Amy Gorin, MS, RDN, owner of Amy Gorin Nutrition in the New York City area, says.
While we’re losing that muscle, we’re likely to gain body fat and need fewer calories, she adds. This is because muscle burns more calories than body fat. “So it’s very important to make dietary changes, as well as to prioritize exercise, particularly strength training,” Gorin says.
Also, women need to think about the hormonal changes that occur with aging. “As you hit menopause and your estrogen levels begin to dip, you’re more prone to gaining weight around the middle,” Gorin says.
It’s also important to think about helping to keep brain and cardiovascular health in top shape.
All of these are heavily influenced by lifestyle.
