Obstructive sleep apnoea is closely linked to metabolic syndrome and its components such as obesity and cardiovascular disease. Weight reduction and dietary restrictions play a major role in reversing OSA.

Obstructive Sleep Apnea May Be Improved With Low-Energy Diet: A single-center, prospective, observational follow-up study has found that a very low-energy diet leads to improvements in moderate to severe obstructive sleep apnea in obese men, with benefits maintained at 1 year and proportional to weight loss and baseline severity.
