Learn how sleep affects weight management, fat loss, and muscle preservation and how a Dexa Scan helps track body composition changes.

Sleep is often overlooked in conversations about weight management. Most people focus on calories and exercise, but sleep plays a major role in how the body regulates hunger, stores fat, and maintains muscle mass.
Poor sleep can make fat loss more difficult and increase the likelihood of weight gain, even when diet and training are consistent.
