Getting enough and good quality sleep is essential to health. The proportion of people experiencing a sleep problem (e.g. difficulties in initiating or maintaining sleep) several nights per week has increased dramatically (from 51% to 64% in 2001 to 2009). Sleep disruption is often brought upon by obesity as well as medical conditions such as type 2 diabetes, cardiovascular disease, hypertension. All these conditions are also impacted by diet.

This study is exploring the effects of a high versus normal protein weight loss diet effects on sleep quality. Those enrolled will receive a prescribed diet by the study dietitian and asked to follow and consume this diet only for 12 weeks.

This study seeks men and women who are currently overweight but otherwise in good health. Participants are required to attend 4 study visits at the research site over a 3.5 month period and will be compensated up to $500 for participating in this study.
