Obese humans are reported to have increased muscle sympathetic nerve activity (MSNA). Obstructive sleep apnea (OSA) may also be accompanied by increased MSNA. There are laboratory evidence indicating that sleep curtailment in young adults results in a constellation of metabolic and endocrine alterations, including decreased glucose tolerance, decreased insulin sensitivity, elevated sympathovagal balance, increased evening concentrations of cortisol, increased levels of ghrelin, decreased levels of leptin, and increased hunger and appetite.

Fruits & vegetables

As nutrient and fiber-rich, relatively low-calorie foods, fruits and vegetables may help you manage your weight. Since fiber promotes fullness, try enjoying fresh fruits and vegetables in place of less satiating, calorie-dense snack foods, such as cookies and candy. Other than bananas, which may increase mucus production and worsen your symptoms, according to the University of Maryland Medical Center (UMMC), incorporate a variety of colors and types into your overall diet. Fruits and vegetables particularly high in fiber include raspberries, citrus fruits, pears, apples, artichokes, broccoli, cabbage, dark leafy greens, brussels sprouts, sweet potatoes and winter squash.

Low-fat dairy products

Low-fat dairy products supply significant amounts of calcium, vitamin D and protein, which promotes blood sugar balance and fullness between meals. One useful way to reduce your caloric intake and manage your weight, according to "Snoring and Sleep Apnea: Sleep Well, Feel Better," by Ralph A. Pascualy and Sally Warren Soest, involves swapping high-calorie dairy products, such as whole milk and cheddar cheese, out for lower-calorie equivalents, such as skim milk and part-skim mozzarella cheese. Replace heavy cream in recipes and hot beverages, such as coffee, with low-fat milk and enjoy low-fat yogurt topped with fruit in place of cheesecake or ice cream for dessert.
