The world of celebrities has always been associated with promoting different diet trends, and lately, the “one meal a day” diet (Omad) has been gaining popularity among them. Bruce Springsteen and Chris Martin are among those who follow it to manage their weight and stay fit. Omad is a form of extreme fasting diet, where a person consumes all their daily calorie intake in a single, large meal. Although there is limited research on its effects on the human body, claims about its benefits are primarily anecdotal.
