The purpose of the study is to determine if weight loss interventions aimed at lifestyle modification (dietary education, food diary pedometer) result in weight loss in patients with mild-moderate obstructive sleep apnea (OSA) when compared to usual patient care. The secondary purpose of the study is to determine if the amount of weight loss achieved in a 6 month period results in improvements in snoring and other symptoms and in the frequency of apnea on overnight monitoring.
Primary Objective
* To determine if weight loss interventions aimed at lifestyle modification (dietary education, food diary pedometer) result in weight loss in patients with mild-moderate OSA when compared to usual care.
* To determine if the amount of weight loss achieved in a 6 month period result in improvements in objective measures of sleep disordered breathing (AHI).
Secondary Objective
* To determine if the weight loss achieved in 6 months result in improvements in OSA symptoms (e.g., snoring, sleepiness) and quality of life.
* To determine if metabolic parameters (e.g., lipids, glucose) improve.
* To determine if there is improvement in sleep structure and oxygenation during sleep.
