Since obesity increases the chances of having OSA, various diets have been studied for their effectiveness in treating the disease, either as stand-alone interventions or as part of broader healthy lifestyle changes that include exercise and sleep hygiene. Healthy diets[1] — particularly those with anti-inflammatory potential[2] — have been associated with less OSA risk in observational studies. Specific diet interventions have also shown positive effects in people with OSA. A randomized controlled trial testing a paleo-style diet intervention found that sleep apnea symptoms were reduced by the paleo diet compared to a control low-fat diet, but only in participants on the paleo diet who lost significant amounts of body weight.[3] A randomized controlled trial also found that the Mediterranean diet improved OSA symptoms, regardless of weight loss, when it was combined with a lifestyle intervention that included exercise and healthy sleeping habits.[4]

Diet can significantly affect obstructive sleep apnea (OSA) because obesity is a major risk factor; various diets, particularly those with anti-inflammatory properties, have been associated with reduced OSA risk. Studies have shown that both a paleo-style diet (only in people who experienced weight loss) and the Mediterranean diet (with lifestyle changes) can improve OSA symptoms.
