Bruce Springsteen, 76, credits his "lean and mean" physique and high energy to a controversial "one meal a day" (OMAD) diet. When asked by The Times how he stays fit, the rock legend confirmed he typically only eats fruit in the morning and a full dinner, adhering to the OMAD intermittent fasting pattern.
While Springsteen swears by the method, registered dietitians warn it is an extreme approach that poses risks, especially for people over 50. "It can be challenging to meet protein, fiber, and micronutrient needs in a single meal," explains Dr. Wendy Bazilian. Nutritionist Kezia Joy adds that such limited eating can lead to low energy, poor concentration, and disrupted hunger cues, often causing overeating at the one meal.
Although some studies show intermittent fasting can aid short-term weight loss and metabolic health, experts question its long-term sustainability and safety. Potential side effects include hunger, irritability, and risks of disordered eating. For lasting health and energy, dietitians recommend a balanced approach with meals spaced throughout the day to ensure consistent nutrient intake and stable energy levels.
