The cluster of symptoms collectively known as a metabolic syndrome heighten the prospect that with age will come steep cognitive decline, a new study has found.  Researchers followed 7,087 French people over 65 for four years to see what factors were most clearly linked to losses in mental performance that fell short of dementia. Many seniors--including 15.8% of the sample--are diagnosed with metabolic syndrome , defined by these researchers as having two of the following five biomarkers: high blood pressure, a large waist circumference, a high  overall cholesterol reading , a particularly low score on HDL (or "good")

These are great calorie-burning options, but there is something else you can do -- a secret weapon in the fight against flab. It's strength training.
