The Scales Can Lie: Hidden Fat

New Study Argues Even Thin People Can Face Health Risks From Fat; It's 'Normal Weight Obesity'

Among some of the Mayo Clinic study's findings: High body fat among normal-weight men and women was associated with a nearly four-fold increase in the risk for metabolic syndrome—a cluster of abnormalities including elevated blood sugar and blood pressure. This syndrome is common among people who are obese and is an increasingly important precursor to diabetes and cardiovascular disease. For women, high body fat meant a heightened risk of being diagnosed with cardiovascular disease over the course of the study. Both men and women had a higher risk of abnormal cholesterol and men with high body fat were more likely to develop high blood pressure.

The findings of the Mayo study, which was published in November in the European Heart Journal, suggest that reducing heart risk requires increasing the percentage of lean muscle mass at the expense of body fat. That underscores the importance of exercise in maintaining cardiovascular health—including weight lifting and other resistance training, which helps build lean body mass.
