Mentioning that he used to do “crazy workouts,” he continued, “That time, if I went to the gym at 6.30 pm, I would continue till 10.30 pm.”

Candidly admitting he thinks intermittent fasting works, he said he is not in favour of any other diets unless a role demands it.

Quantifying his diet, he said, “I know that 250 grams of rice, 150 grams of vegetables, some protein of 150-200 grams, and drinking water works. If I base it on not overeating, I think that works for muscle building, unless you are in a competitive sport where you need more protein and muscle. I think on regular days you shouldn’t follow all these diets. Right from the start, I never knew anything. Eat nicely, people would say. I would eat 5-6 full meals. Now, that is discarded.”

Admitting that he has tried “intermittent fasting for drastic weight loss,” which “definitely works”, he shared that he has not been eating for “3 days now”. “I am just drinking water. I have to drop 4-5 kilos. I have been told not to run on the treadmill because I ran to catch a flight inside the airport. I strained my leg. So, I was told to do only the rowing machine and no treadmill. So, when you don’t run on the treadmill for one hour, you don’t sweat that much. So, I thought I should lose weight. I have been having beetroot juice and water,” the Por Thozhil actor expressed.

From a clinical perspective, consultant dietitian and fitness expert Garima Goyal noted that exercising consistently for five decades is remarkable. “Long-term physical activity is associated with better muscle preservation, cardiovascular health, bone density, mobility, and cognitive function. Sarathkumar’s fitness journey reinforces the idea that regular movement, rather than short bursts of intense exercise, is one of the strongest predictors of healthy ageing,” said Goyal.

However, his statement about fasting for three days to lose 4-5 kilos needs important context. “A significant portion of the weight lost during a prolonged fast is usually due to depletion of glycogen stores and associated water loss, rather than pure body fat reduction. Since glycogen stores bind water, reducing food intake can lead to a rapid drop on the weighing scale,” said Goyal.

While short-term fasting may have certain metabolic benefits in selected individuals, a 3-5-day fast is not appropriate for everyone. “Prolonged fasting can cause fatigue, dizziness, electrolyte imbalances, headaches, reduced exercise performance, and loss of lean muscle mass if not supervised properly. Individuals with diabetes, medical conditions, pregnant women, and older adults should be particularly cautious,” said Goyal.

From a nutrition standpoint, rapid weight loss strategies are often used by actors and athletes for specific deadlines or aesthetic requirements, but they should not be mistaken for sustainable fat-loss approaches. “Long-term health and body composition are better supported by a balanced calorie deficit, adequate protein intake, resistance training, and consistency,” said Goyal.
