Midlife Weight Gain: Don't Blame Your Metabolism


Most of us reach our final adult height at around age. Eighteen or twenty. Unfortunately that doesn't mean that we stop growing on. Average americans continue to gain a pound or two a year every year from the time they reach adulthood until age sixty or so when this trend starts to reverse of course by then a lot of damage has been done although gaining a single pound or two over. The course of a year isn't going to make a big difference in your health gaining thirty or forty pounds over the course of your adult lifespan can have a significant negative impact. On your risk of diabetes heart disease cancer and other conditions related to obesity such as knee pain and sleep apnea so what drives this weight gain in middle age. There's long been an assumption that this seemingly universal trend is due at least in part to a slowing of the metabolism in midlife. We've all been told that our bodies engines simply reva little faster when we're younger and that there's not that much that can be done. If we want to avoid gaining weight through midlife we're going to have to spend more time exercising or adjust our food intake to compensate for this inevitable slowing of the metabolism. Now if you refuse to go gently into this good night you can find all kinds of special diets workouts and supplements promising to goose up your middle aged metabolism to the extent that any of these actually succeed in boosting your resting metabolic rate. The effect is likely to be quite small as i've said before trying to lose weight by boosting. Your metabolism is like trying to row a boat with a butter knife. You're going to be rowing for an awfully long time. Without moving very far but a new study is during all of these assumptions about midlife metabolism into the blender researchers used a sophisticated technique called the doubly labeled water method to measure energy expenditure in a diverse population of over six thousand people and these subjects ranged in age from newborn to ninety five years old and they also came from a wide variety of ethnic backgrounds and cultures and the results were almost exactly the opposite of what our observations might have led us to believe not surprisingly are metabolic rate is highest when we're babies it peaks at about twelve months of age and then declined steadily until we reach early adulthood but then our metabolic rate is remarkably stable from age twenty to age sixty. There is virtually no slowing in
