Some might say these are normal indicators of aging and we can afford to ignore them. But when you consider that 50 percent of people with insulin resistance will become diabetic within 5 to 10 years, I think it’s critical to heed these warnings before finding yourself on the road to serious health problems.

Relative Fat Mass Estimation

Although BMI is used by physicians as a guideline for determining normal or abnormal weight, it’s not very reliable when it comes to estimating body fat (or adiposity) as a percentage of total body mass. As a result, it tends to underestimate adiposity in those with less lean muscle mass, especially the aged, and overestimate it in lean, muscular individuals, especially athletes. For example, most football running backs would be considered overweight or obese according to BMI despite being very lean.

A simple and more accurate way to determine body fat is to use a formula recently devised by Orison Woolcott and Richard Bergman at Cedars-Sinai Medical Center. Rather than estimate relative body mass, this calculation approximates relative fat mass, or RFM. The formula is slightly different for women and men because women have higher amounts of subcutaneous fat, which does not correlate with poor health outcomes.

Women: 76 – (20 × (height ÷ waist circumference)) = RFM

Men: 64 – (20 × (height ÷ waist circumference)) = RFM
