As we age our metabolic rate naturally slows down, just another joke Mother Nature plays on us. According to researchers at the University of Colorado, sedentary postmenopausal women have roughly a 10 percent decrease in their BMR. That would help to explain the common complaint of women who are in their 40s and 50s: weight gain and an inability to lose weight as they were able to before.
To combat the impact age has on our metabolic rate, we need to step up our game -- beginning in our 40s, we need fewer calories, about 200 fewer, to help maintain our weight. And don't forget physical activity. No matter what our age, exercise and strength training are key to increasing metabolic rate and losing weight.
