Weight loss leads to proportionately fewer symptoms of sleep apnea, and apnea appears to be associated with diabetes and hypertriglyceridemia.

This study addressed two questions: Does weight loss improve the symptoms of obstructive sleep apnea (OSA), and is the development or persistence of OSA an independent risk factor for metabolic abnormalities?
