Dr. Jonathan Greenburg from Zyppah explains the link between snoring and weight gain, noting that disrupted REM sleep caused by snoring can lower leptin levels, the hormone that helps regulate hunger. This drop in leptin can increase appetite, trigger carb cravings, and slow down metabolism. To address this, Dr. Greenberg developed Zyppah, a unique mouthpiece featuring a tongue strap, which proved 91% effective in clinical trials involving more than 600 patients.
