Our metabolism and body changes so much as we get older that what kept you trim in your 20s is unlikely to help you shed pounds in your 50s, according to the latest research.
"There isn't a one-size-fits-all plan that works for life unfortunately," says nutritionist Linda Foster. "Because the way our bodies process food changes pretty much every decade."
And not only does a weight-loss diet have to be tailored to suit our age, our body's nutritional needs vary over the years too.
During child-bearing years, for example, iron and folic acid are vital. But after the menopause getting enough omega-3 fats and calcium can become more important.
So we've created a diet blueprint for each decade, including specific diet rules and foods for your 20s, 30s, 40s and 50s.
Follow it to hold back the years and make the best of your body - whatever decade you're in.
