Your metabolism slows down. This happens naturally, but it becomes more pronounced if you don’t get as much exercise as you should. When your metabolism slows, your body doesn't burn as many calories, which means you need to eat less to stay at a healthy weight. As a result, the foods you eat should be as nutrient-rich as possible. Most women with average activity levels need about 1,800 calories per day. Men with an average activity level need about 2,300 calories each day. You’ll need fewer calories if you’re sedentary, more if you are very active.
Turning 50 is a milestone for many people. The half-century mark comes with new rules for medical tests and often brings a couple of health-related signals indicating that it’s time for some dietary changes. Even if you have enjoyed a healthy 50 years or more, nutritional needs change over time. Gradual dietary tweaks may be wise to ensure your golden years are, well, golden.
