Changes in regional body composition over 8 years in a randomized lifestyle trial: The look AHEAD study

  • Published on Jul 28 2016

Objective: To test the hypothesis that an 8-year intensive lifestyle intervention (ILI) suppresses aging-dependent changes in regional lean mass (LM) and fat mass (FM) among people with overweight/obesity and type 2 diabetes. Methods: Regional body composition was measured by dual-energy X-ray absorptiometry within a subset of 1,019 volunteers (45–75 years old) in ...
