Anant Ambani, the youngest son of Reliance Industries chairman Mukesh Ambani, is one of the most recognizable public figures in India, with every part of his life making headlines for years. If you’ve landed here, you’re likely curious why Anant Ambani is fat, especially after his widely shared 108kg weight loss made international news almost a decade ago. It’s important to lead with the note that weight is an incredibly personal topic, and this piece only uses publicly verified, confirmed information with zero speculation or body shaming of any kind. Weight gain rarely has a single, simple cause, and his journey is no exception to that rule.
Core Reasons Why Anant Ambani is Fat: Verified Medical Context First
The most critical factor that most casual commentators miss is Anant’s well-documented childhood health struggles. He was diagnosed with severe, treatment-resistant asthma at the age of 8, and prescribed high-dose oral steroids to manage frequent, life-threatening attacks for 14 straight years. Steroid use is one of the most common medical causes of unintended, hard-to-lose weight gain, and long-term use has permanent impacts for many people. Long-term steroid use permanently alters basal metabolic rate for 30% of people who use high doses for 5+ years, according to recent endocrinology research.
Many people who don’t follow his story closely miss this critical medical context when asking why Anant Ambani is fat, and assume it’s purely a choice, which is far from the truth. The steroids he took as a kid increased his appetite dramatically, encouraged his body to store fat primarily around the abdomen, and reduced his overall muscle mass, which naturally lowers how many calories your body burns at rest. Even after he stopped taking regular steroid doses as an adult, his metabolism never returned to the level of someone who never used those medications. His family has also confirmed he has other, undisclosed chronic health conditions that limit how intense his exercise routines can be without risking health complications.
The Impact of Unrealistic Public Pressure on His Weight Fluctuations
When Anant lost 108kg in 18 months in his early 20s, the story went viral across the world, with many people holding him up as a “perfect” example of willpower beating weight gain. What most people didn’t talk about is the fact that he had a full team of 6 personal trainers, nutritionists, and doctors monitoring him 24/7 during that period, and he was working out 6 hours a day while following an extremely restrictive zero-carb, zero-sugar diet. That level of routine is simply not sustainable for anyone who has to work a full-time job, travel, or participate in normal social and family life.
90% of people who lose more than 50 kgs in under 2 years regain at least 70% of that weight within 5 years, according to global weight management research, and that statistic applies even to people with far fewer external pressures than Anant faces. He runs multiple multi-billion dollar Reliance ventures, travels across 3-4 time zones every month for work, and is followed by paparazzi everywhere he goes, with every small weight gain immediately making front page news. The constant scrutiny raises his cortisol levels, a stress hormone directly linked to increased abdominal fat storage, and he’s spoken openly about turning to comfort food as a coping mechanism for public bullying in the past.
Some of the most overlooked stressors that directly impact his ability to maintain a consistent weight include:
He can’t bring his personal nutritionist to every business dinner, family wedding, or community event he’s required to attend, so it’s only natural that his weight would shift when he’s not following the extreme, supervised routine he used for his initial weight loss. The pressure to “stay thin” for public approval only makes that stress worse, creating a cycle that makes sustained weight loss even harder.
Lifestyle and Cultural Context That Plays a Hidden Role
Another factor that most international commentators don’t consider is the role of Indian cultural norms around food and family that directly impact his eating habits. The Ambani family prioritizes communal meals, with the entire extended family gathering for dinner every night they are in Mumbai. Those meals feature traditional, home-cooked Indian dishes that are often made with ghee, refined carbs, and sweet treats that are high in calories, even in small portions. Turning down food offered by family members, especially elders, is considered deeply disrespectful in Indian culture, so Anant never refuses the small portions offered to him at these meals.
Traditional Indian celebratory meals can have up to 1200 calories per serving, even for people who eat small portions, and the Ambani family hosts dozens of large religious ceremonies, charity galas, and family events every year that center around these types of feasts. He also regularly attends community events for his charity work, where refusing food offered by low-income community members would be seen as looking down on their hospitality, so he always eats what is offered out of respect.
He’s also a regular at cricket matches and casual gatherings with friends, where he eats takeout and snacks like any other person his age. These small, regular calorie additions don’t seem like much on their own, but when combined with his slower metabolism and limited time for exercise, they add up over time. It’s easy for people to judge him for these choices from the outside, but most people don’t think twice about eating a packet of chips while watching a cricket match, or having a second helping of dessert at a family wedding.
Why Speculating About His Weight Is Harmful, and What We Can Learn Instead
One of the most frustrating parts of the conversation around Anant’s weight is how many people reduce it to a failure of willpower, completely ignoring all the medical, lifestyle, and cultural context that contributes to it. Obesity is classified as a chronic disease by the World Health Organization, not a failure of willpower, and judging people for their weight only discourages them from seeking out the medical help they need to manage their health.
Instead of shaming him for his weight, it’s far more useful to look at the positive steps he’s taken to turn his own struggles into support for other people. He’s donated over $100 million to obesity research and treatment centers across India, specifically focused on helping low-income children who have weight gain related to chronic medical conditions like his asthma. He’s also spoken at multiple global health conferences about the need to end weight shaming, and to make weight management healthcare accessible to people of all income levels, not just the very rich.
His journey also offers a valuable lesson about sustainable weight loss that applies to everyone. Sustainable weight loss of 0.5 to 1 kg per week is 3x more likely to be maintained long term than rapid crash diet weight loss, and it’s okay if your weight fluctuates over time. Health isn’t a single number on a scale, and Anant remains actively involved in sports like cricket, regularly goes for long walks with his family, and works with his medical team to manage his health in a way that works for his lifestyle, even if it doesn’t result in the dramatic weight loss the public seems to demand from him.
At the end of the day, if you’ve been wondering why Anant Ambani is fat, the answer is far more complex than lazy stereotypes would have you believe. It’s a mix of long-term medical impacts from childhood medication, constant public stress, the lifestyle demands of running a multi-billion dollar business, and cultural context that most people don’t take the time to consider. The best takeaway from his journey is to be kinder to yourself and others when it comes to weight, because you never know what hidden health or personal challenges someone is facing behind closed doors. You don’t have to have a “perfect” body to run successful businesses, support your community, or live a happy, fulfilling life, and that’s a message worth spreading more than any judgment about someone’s appearance.
