What is OMAD? Extreme form of intermittent fasting Karan Johar and Shah Rukh Khan follow for toned bodies in their 50s
As per an April 17 report on IndiaToday.com, filmmaker Karan Johar shared during his Instagram Live that he was on a strict diet and eating just one meal a day to lose extra kilos and stay in shape. Speaking with The Guardian in an August 2024 interview, actor Shah Rukh Khan also shared that he only eats one meal a day, but clarified that it was his personal choice.
Read on for a more detailed look at OMAD.
In a November 2024 interview with HT Lifestyle, Dr Rakesh Gupta, senior consultant in internal medicine at Indraprastha Apollo Hospitals shared that the OMAD diet, a form of intermittent fasting, 'has gained attention for its potential to facilitate rapid weight loss'.
According to Dr Gupta, this approach involves consuming all daily caloric intake in a single meal, 'typically within a one-hour eating window, while fasting for the remaining 23 hours'. He said, 'The diet is believed to create a significant calorie deficit, which can lead to weight loss. Proponents argue that it simplifies meal planning and allows for greater food variety during the single meal.'
While the OMAD diet might offer quick weight loss results for some individuals, Dr Gupta warned that these benefits must be balanced against potential health risks. He said: 'Long-term adherence could lead to nutritional deficiencies and other health complications.'
He added, 'Consulting with healthcare professionals before starting such an extreme dietary regimen is advisable, particularly for those with pre-existing health conditions or concerns about sustainable weight management strategies. A more balanced approach that incorporates regular meals with nutrient-rich foods may be more beneficial for long-term health and well-being.'
⦿ Rapid weight loss: Many individuals report significant weight loss due to drastic calorie reduction, Dr Gupta said. The diet could lead to fat loss while potentially improving metabolic health markers such as blood sugar levels and inflammation, he added.
⦿ Simplicity: With only one meal to prepare and consume, followers often find it easier to manage their eating habits without the need for constant meal planning or calorie counting, Dr Gupta said.
⦿ Flexibility in food choices: Unlike many restrictive diets, OMAD does not typically limit food types, allowing individuals to enjoy a wide range of foods during their meal, he added.
⦿ Nutritional deficiencies: Consuming only one meal a day might lead to inadequate intake of essential nutrients, according to Dr Gupta. This could result in deficiencies that affect overall health and well-being.
⦿ Increased hunger and cravings: Many followers experience intense hunger throughout the day, which could lead to irritability and difficulty concentrating, Dr Gupta said, adding that this might increase the risk of binge eating during a single meal.
⦿ Potential for muscle loss: Dr Gupta said rapid weight loss might not exclusively come from fat; muscle mass could also decrease, negatively impacting metabolism and physical strength.
⦿ Mood swings and fatigue: The extreme calorie restriction associated with OMAD could lead to mood fluctuations and fatigue due to unstable blood sugar levels, Dr Gupta said.
⦿ Long-term sustainability issues: Many individuals find OMAD difficult to maintain over time, with dropout rates reported as high as 65 percent, according to Dr Gupta. The restrictive nature of the diet might not be suitable for everyone.

Hidden impact of enlarged male breast on Indian men, why surgery is the only fix
For many Indian men, a health issue that rarely finds a voice in public conversations is gynecomastia, commonly referred to as "man boobs," a condition that leads to the development of breast tissue in harmless in most cases, it can lead to deep psychological distress, especially when left is most common in men between the ages of 20 and 40, though it often begins around puberty. Hormonal changes during adolescence are the usual trigger, and for some boys, about one in six to eight, this hormonal shift results in the formation of visible breast "In most cases, the hormonal imbalance corrects itself once puberty is complete. But the tissue that formed during the imbalance doesn't go away on its own," Dr. Rajat Gupta, plastic surgeon and Founder of RG Aesthetics, New Delhi, and the National Secretary of the Indian Association Of Aesthetic Plastic Surgeons, tells 'This is not fat that can be burned with exercise or reversed with pills. It's actual glandular tissue, and the only way to remove it is through surgery.'PSYCHOLOGICAL DISTRESSWhile the condition may seem superficial to some, the emotional toll it takes is very real. Social embarrassment, teasing, and body-shame are common experiences, especially for teenagers and young Gupta recalls one particularly harrowing case - a 14-year-old boy who faced relentless bullying in school because of his chest. The ridicule was so intense that he dropped out and eventually attempted to mutilate his chest with a kitchen knife in a desperate attempt to "fix" himself.'It left a deep scar, both physically and mentally. Even though I usually prefer to wait until a patient is 17 or 18, in this case, the psychological trauma was so severe, we had to go ahead with the surgery earlier," says Dr. ABUSEWhile puberty is the most common trigger, another major cause is self-inflicted - anabolic steroid use. As gym culture intensifies across Indian cities, Dr. Gupta sees a steady stream of young men developing gynecomastia due to performance-enhancing drugs.'These steroids convert into estrogen in the male body, which then stimulates breast tissue growth. We see about 30 to 35 patients a month with gynecomastia. Many of them are regular gym-goers who didn't know the risks of steroid use," he many other health conditions, there are no medical treatments or home remedies that can reverse gynecomastia once it sets no medicine that can melt this tissue. "People try weight loss, hormone therapy, or herbal supplements, but nothing works. Surgery is the only effective treatment," adds Dr. THE SOLUTION?Traditionally, gynecomastia surgery leaves a small scar on the chest, something that, ironically, can be just as emotionally distressing as the condition give someone a flat chest and then leave a visible scar on the front defeats the purpose. These are patients who avoid beaches, pools, or tight T-shirts because of their appearance. If there's a scar there, the psychological block remains," says Dr. what led him to develop a new method — the Occult of cutting through the front of the chest, the incision is made discreetly on the side. The scar is tiny, only 4 to 5 millimetres, and eventually fades to resemble a minor acne mark.'It's a daycare procedure — you walk in the morning, walk out the same evening. You can start normal activities from the next day and resume light exercise in two weeks,' he IT EVER COME BACK?For most patients, the results are permanent. Recurrence is extremely rare unless there is an underlying hormonal disorder or the person goes back to steroid use.'As long as we've ruled out any medical causes, it's a one-time fix,' says Dr. many men, undergoing this surgery is not about vanity, it's about reclaiming their confidence and quality of life. Yet, due to the stigma, most suffer in silence, never discussing it with friends or family.- Ends advertisement

Rising COVID cases in United States: What do families need to know about booster vaccination in 2025?
COVID booster vaccines 2025 : As kids head back to school and families settle into the end-of-summer routine, COVID-19 is starting to make a comeback across the US Cases are rising again, though not as dramatically as in past years, at least, not yet, as per a report. Rising COVID Cases: What's Different This Time? According to health experts, it's too soon to tell just how big this late-summer wave could get. What makes it harder to predict this time around is that people have all sorts of different immune histories due to prior infections and vaccinations, which means COVID might hit some harder than others, according to The Guardian report. Productivity Tool Zero to Hero in Microsoft Excel: Complete Excel guide By Metla Sudha Sekhar View Program Finance Introduction to Technical Analysis & Candlestick Theory By Dinesh Nagpal View Program Finance Financial Literacy i e Lets Crack the Billionaire Code By CA Rahul Gupta View Program Digital Marketing Digital Marketing Masterclass by Neil Patel By Neil Patel View Program Finance Technical Analysis Demystified- A Complete Guide to Trading By Kunal Patel View Program Productivity Tool Excel Essentials to Expert: Your Complete Guide By Study at home View Program Artificial Intelligence AI For Business Professionals Batch 2 By Ansh Mehra View Program Vaccine Access May Be More Limited This Fall Another issue is that just as cases begin to rise, there's growing uncertainty around who will actually be eligible for a booster this fall because of the new vaccine restrictions from the Trump administration, as per the report. Andrew Pekosz, a virologist at Johns Hopkins University pointed out that, 'If you're vaccinated against Covid-19, you're less likely to get infected,' adding, 'But we haven't gotten a lot of people vaccinated for the past few years, and with the current recommendations changing, it's even less likely,' as quoted in The Guardian report. Pekosz also highlighted that future waves of COVID could become more severe as vaccination lags and immunity drops, as per the report.

Right now, several signs point to a slow but steady uptick in COVID activity. Wastewater data, test positivity, and emergency room visits are all climbing, especially in southern and midwestern states, according to the report. Pekosz said that, 'In the snapshot that we're seeing right now, increases are happening at a relatively low rate, and that would indicate that we probably aren't going to peak at a very high level. But again, this is early in this summer surge, so we really have to keep monitoring the data and paying attention to what it's telling us,' as quoted by The Guardian.

New COVID Variants Are Better at Dodging Immunity What's different now is the virus itself. The versions currently spreading have evolved to better dodge our immune systems. That makes the situation more unpredictable and potentially more dangerous for people who haven't stayed up to date with boosters, according to The Guardian report. Booster Vaccination Rates Are Low, Especially Among Kids Here's one of the bigger concerns this time around: not many people have been vaccinated recently. Only about 23% of adults got the updated booster as of this spring. Among kids aged 6 months to 4 years, it's just 5.6%, and about 15% of children aged five to 17 are vaccinate, as per The Guardian report. Who Will Be Eligible for COVID Booster Vaccines? This comes as the rules around boosters might change, as the government is considering limiting the updated boosters to older adults for those over 65 years and people with specific health conditions, as per the report. That means fewer people, including kids, younger adults, and pregnant people, might have access to the updated vaccine unless they meet certain medical criteria, according to The Guardian. According to the latest proposal from the FDA, people with health conditions like asthma, diabetes, or even depression and physical inactivity could qualify, as per the report. But there are still a lot of questions. Uncertainty Over COVID Vaccination Sam Scarpino, a professor of health sciences at Northeastern University pointed out that, 'So it's a big question mark, going into the fall, is who it's going to be approved for,' adding, 'If it's not approved, can you still pay out of pocket for it? How much is it going to cost? And then are there going to be supply chain issues?,' as quoted by The Guardian. Pekosz highlighted that the Trump administration is moving away from the approach of immunising broad swaths of the population, especially those most likely to get and pass the virus on, like children, according to The Guardian report. Experts Urge Broad Vaccination to Prevent Spread However, he emphasised that, 'If you vaccinate broadly, you can reduce the spread of Covid-19 in the population,' adding, 'The benefit, to me, is very clearly on the side of getting vaccinated,' as quoted in the report. FAQs Are COVID vaccines still effective? Yes. While not perfect, vaccines still help prevent severe illness and reduce transmission. What can I do to protect myself right now? Get vaccinated if you're eligible, mask up in crowded spaces, and stay home if you're feeling sick.
