Mayo clinic probes belly fat's stubbornness with niacin test

This study looks at why people who carry extra weight around their belly have fat cells that don't respond normally to signals that should 'turn off' fat release. Researchers at Mayo Clinic will give niacin (a B vitamin) to 32 overweight and lean adults and measure how their fat tissue responds. The goal is to understand the differences in fat cell behavior, not to treat or cure weight gain.
