Actor R Madhavan shared his weight loss journey, revealing how he shed kilos in just 21 days through a disciplined routine focusing on intermittent fasting, heavy chewing of food, and early dinner times. By avoiding processed foods, consuming plenty of fluids, and prioritizing green vegetables, Madhavan emphasized the importance of hydration and easily metabolized foods. Intermittent fasting not only aids in weight loss but can also improve metabolic health, reducing the risk of type-2 diabetes and heart disease. Despite his successful transformation for the film 'Rocketry: The Nambi Effect', Madhavan's approach may vary in effectiveness for individuals, urging a cautious and personalized approach to weight loss journeys.
