Jung Kook of BTS has revealed that he follows the One Meal A Day (OMAD) diet, consuming all his daily calories within a single hour and fasting for the remaining 23 hours. The disclosure comes ahead of the group’s anticipated comeback in March 2026. While the announcement has sparked curiosity among fans, particularly in India where K-pop influence is rising, health experts caution that such an extreme regimen may not be suitable for everyone.

OMAD is a restrictive form of intermittent fasting that limits eating to one substantial meal per day. Calorie requirements vary significantly depending on body type, gender and activity levels. According to guidelines by the Indian Council of Medical Research (ICMR) and the National Institute of Nutrition (NIN), Indian men with high-intensity lifestyles may require up to 3,000 kcal per day. Consuming such energy needs in a single sitting can be challenging and may not support sustained physical performance.

Research published in Frontiers in Physiology suggests that extreme fasting methods like OMAD may contribute to modest weight loss, improved insulin sensitivity and enhanced fat metabolism, particularly when combined with structured exercise. However, studies also highlight concerns regarding adherence and long-term sustainability. Reduced meal frequency can affect endurance, strength and nutrient absorption if not carefully monitored under medical supervision.

Jung Kook’s disciplined routine is shaped by his rigorous training and previous military service, which instilled a regimented lifestyle. Health professionals note that celebrity diets are often customised and medically supervised, making them difficult to replicate safely. For the average individual, especially adolescents and young adults with active schedules, eating once a day may result in nutrient deficiencies, fatigue and digestive stress.

In the Indian context, experts stress the importance of balanced dietary patterns tailored to local nutritional needs. Skipping meals may worsen common concerns such as anaemia, diabetes or metabolic disorders. Safer alternatives include moderate intermittent fasting (12–14 hours), balanced portion control and diverse meal plans incorporating fruits, vegetables, proteins and whole grains. While OMAD may work for certain individuals, experts advise consulting healthcare professionals before adopting any restrictive diet influenced by celebrity trends.
