Gut health is the root cause of unexpected weight gain and cravings
Over the last few years, there has been increasing medical opinion that much of the body's health problems like weight gain and perpetual hunger could be originated in the stomach.
For Indians with unexplained weight loss or gain in spite of regular food or measured portions, the solution could lie not in the food they eat but the way the body processes and digests it.
The gut, or gastrointestinal tract, is inhabited by trillions of bacteria that comprise what's called the gut microbiome. This intricate community of microorganisms dictates everything from digestion and nutrient consumption to immunity, metabolism, and even mood.
If this balance is disrupted a process called dysbiosis it can set off a sequence of metabolic and hormonal reactions that lead to weight gain, bloating, fatigue, and cravings for unhealthy foods.
Here's how body weight is affected by gut health:
1. Gut bacteria and metabolism
Some species of gut bacteria are responsible for the breakdown of food and its conversion to energy directly. Their imbalance slows down metabolism and leads to fat storage in the body even when calorie consumption is not higher.

A non-diverse gut may also release fewer short-chain fatty acids, which are proven to suppress appetite and fat burning.
2. Effect on
hunger hormones
and cravings
An unhealthy gut can elevate levels of ghrelin (the hunger hormone) and lower leptin (the satiety hormone), leaving individuals hungrier more frequently. This imbalance may result in constant cravings, particularly for sugar and processed foods a complaint that most Indian patients with unpredictable eating habits raise.
3. Role of antibiotics and processed foods
The overuse of antibiotics, and even consumption of highly processed foods, can destroy the lining of the gut and eliminate beneficial bacteria. Self-medication and frequent use of antibiotics are extremely prevalent in India and lead to chronic digestive imbalances.
4. The stress connection
Stress, which is widespread in Indian urban lifestyles, can modify gut microbiota and enhance inflammation. The gut-brain axis two-way communication between the digestive system and the brain — implies that stress has a direct effect on digestion and appetite regulation.
How to Enhance Gut Health for Weight Management:
- Boost dietary fiber with vegetables, fruits, and whole grain foods.
- Eat fermented foods such as curd, buttermilk, idli, and dosa to restore good bacteria.
- Don't overuse antibiotics.
- Exercise daily and stress manage with yoga or meditation.
- Take probiotics under medical supervision.

What is taurine, the anti-aging supplement going viral — and is it worth the hype?
In the ever-growing hunt for the fountain of youth, taurine has suddenly taken center stage. From biohacking forums to longevity labs, this naturally occurring amino acid is being hailed as a potential game-changer in the science of aging. Found in the human body and in certain foods, taurine supplements have shown promising effects in lab animals, slowing signs of aging and even extending lifespan. But does this mean popping taurine pills will keep humans younger for longer? A major new study just published in Science is complicating the picture. Taurine and aging: Hope vs. Hype Taurine levels decline with age—or at least, that's what some earlier studies suggested. These studies sparked excitement about taurine supplements as a possible anti-aging therapy. However, most of this research was cross-sectional, meaning it looked at different age groups at a single point in time. This method often yields conflicting results, with some papers suggesting taurine levels drop with age, while others show stability or even increases. To dig deeper, researchers from the U.S. National Institute on Aging (NIA) and other institutions published a new study on June 5, 2025, in Science that combines both cross-sectional and longitudinal data—where the same individuals are followed over time. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Your Finger Shape Says a Lot About Your Personality, Read Now Tips and Tricks Undo The results challenge the foundational assumption: taurine levels don't seem to drop as we age. The big reveal: Taurine doesn't always decline "The main takeaway is that a decline in taurine is not a universal feature of aging," said Dr. Joseph Baur, a professor of physiology at the University of Pennsylvania Perelman School of Medicine, who was not involved in the study, in a statement to Live Science . The study tracked over 740 participants from the Baltimore Longitudinal Study of Aging, ranging from 26 to 100 years old. It also included people aged 20 to 85 from the Balearic Islands Study in Spain, 160 people aged 20 to 68 in the Predictive Medicine Research cohort in Atlanta, and even rhesus macaques and lab mice at varying life stages. In most cases, taurine levels either increased or remained steady over time. Maria Emilia Fernandez, a postdoctoral fellow at the NIA and co-author of the study, explained during a June 3 news conference, 'The differences in taurine levels seen between individuals generally is far greater than the degree of change seen across adulthood.' Low taurine, she concluded, is 'unlikely to serve as a good biomarker of aging. ' Only two subgroups in the study showed no increase in taurine levels: male mice in one part of the experiment, and men from the Predictive Medicine Research cohort. Scientists aren't sure why. Researchers also looked for correlations between taurine levels and health markers like muscle strength—commonly associated with aging. But the findings were 'inconsistent within and across cohorts,' said Fernandez, casting doubt on taurine's role in driving age-related decline. What past studies showed In 2023, a study co-authored by Vijay Yadav of Rutgers New Jersey Medical School found that middle-aged mice given taurine showed better sugar metabolism and less DNA damage. The new study didn't replicate or examine those effects, leaving parts of the aging puzzle unresolved. Adding to the complexity, taurine levels vary wildly based on health status. In obese individuals, taurine drops—until it surges again in cases of severe obesity. In cancer patients, taurine increases in leukemia but drops in breast cancer, according to Fernandez. As for what taurine does in a healthy body: it's critical for forming bile salts, aids in fat digestion, supports mitochondrial protein production, and boosts antioxidant supply. No, taurine isn't a miracle biomarker Rafael de Cabo, chief of the NIA's Translational Gerontology Branch and co-author of the study, was clear during the news conference: 'The short answer is no — it's not a reliable biomarker of anything yet. I think that we need to be digging into the basic mechanisms … before it can be used reliably as a marker.' Dr. Luigi Ferrucci, a co-author of the new study and scientific director at the NIA, summed it up best: 'There is a discrepancy between different studies, and this discrepancy needs to be analyzed more in depth. They may reveal some important mechanisms with aging that could be … a target for intervention.' So while taurine remains an intriguing lead in the quest to slow aging, science still has a long road ahead before it becomes a reliable treatment—or a staple in your supplement stack.

Bihar pushes up its Ayushman Bharat health insurance coverage
Bihar is now among the Indian States leading in the enrolment of cardholders under the Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY), with 3.94 crore Ayushman cards created till date, according to data released by the State government. It has also helped beneficiaries save over ₹1,000 crore in out-of-pocket medical expenses within a single year. Bihar is the third most populous State in the country, with about 80% rural population, and a literacy rate of less than 70%. It faces health challenges, including high infant and maternal mortality rates, malnutrition, and limited access to quality healthcare. As part of its drive to ensure maximum coverage, a recent four-day drive, from May 26-30, brought 17.38 lakh more cardholders into the Central government-run cashless health insurance scheme, offering treatment for secondary and tertiary care hospitalisation for the economically weaker sections of society. Uttar Pradesh and Madhya Pradesh are the other two States that have recently indicated a high enrolment rate. The flagship health insurance scheme, launched in 2018, offers cashless healthcare treatment of up to ₹5 lakh per family per year. Initially, the State Government had adopted the Socio Economic Caste Census (SECC 2011) data for implementing the AB-PMJAY scheme, Shailesh Chandra Diwakar, Administrative Officer, Bihar Swasthya Suraksha Samiti (Ayushman Bharat), said on the recent focus to expand the coverage of the Ayushman card. In February 2024, the Bihar Government adopted the National Food Security Act (NFSA) database and provided coverage to all NFSA-registered family members. 'This saw many more ration cardholders coming into the AB-PMJAY fold. More than 2.8 crore Ayushman cards were created in 2024,' Mr. Diwakar said. Besides this, the State has launched various measures, including an enhanced cash incentive of ₹15 (from ₹5) to ASHA workers involved in verified enrolments; camps at railway stations to capture those in need when people travel back into the State for festivals; and door-to-door campaigns. 'These extensive mop-up rounds are for individuals who have been left behind,' Shashank Shekhar Sinha, CEO, Ayushman Bharat (PMJAY-Ayushman Bharat Digital Mission), said. The State has also recently registered enrolment of 2.82 lakh persons under the Ayushman Vaya Vandana card (for senior citizens 70 years and above). According to the State government, the total claims paid rose from 3.03 lakh cases in FY 2023-24 to 7.52 lakh cases in FY 2024-25, and more than 2.83 crore Ayushman cards were created in 2024. A first time Ayushman card user, speaking of his enrolment, and experience with availing the treatment, said that he had had his card made only after he reached the hospital to be treated for cataract. 'Though we had heard about the Ayushman card, since we didn't need hospitalisation, we never got the card made,' Lalan Choudhary, a resident of Bihar's Nalanda district, who is now undergoing free treatment at a private healthcare facility in Gaya under the AB-PMJAY, said. 'This is a problem we are facing in the State — though people know about the card, they will enrol under the scheme often only when they seek treatment,' Mr. Diwakar added. The State is now trying to rope in eligible individuals who have not opted for the scheme. Khushi Praveen, 19, who was operated for spinal deformity 10 days ago, speaking about her use of the Ayushman card, said that she had been suffering for a nearly a year without money to secure treatment and surgery. 'Though I needed surgery, without money, there was no access to healthcare. My doctor in the private sector suggested that I get my Ayushman card and get operated. Using the card, I got surgery and am healing well now, and hope to be able to walk soon,' Ms. Praveen said. Parmilla Devi, 50, had her cataract operation performed under the scheme. 'My husband and I work as farmers and couldn't have afforded the surgery otherwise. My husband is also now planning to apply for his card also,' Ms. Devi said. Rajaram Prasad, Chief Surgeon, Gaya district, said that in Gaya district (one of the 38 districts in Bihar), which is seeing robust enrolment and use of the card, in 2024-25, a total of 18,734 people were treated in government hospitals at an expense of about ₹15 crore under the Ayushman scheme. 'Affordable, quality medical care is now no longer a distant dream for the rural population of Bihar,' Dr. Prasad said. Besides the enrolment of more individuals under the scheme, Bihar is also looking at enhancing the number of hospital service providers. Currently, over 1,100 hospitals are empanelled under the scheme in Bihar, 50% of which are private hospitals, a senior Bihar health official.

A common supplement can remove toxic 'forever chemicals' from your body
Image credits: Getty Images It has been said for years that nature has a remedy for every problem out there. While we keep on expanding the horizons of medicine and technology, the field of nature has taken a step back, much to the disappointment of people who know that Mother Earth is the biggest magician and creator of all. A new study is now suggesting that the 'forever chemicals' that enter our body with water and food containing them, can be removed with a common dietary supplement. Oats the solution to PFAS ? Eating a fibre supplement derived from oats prior to every meal could help flush out the toxic forever chemicals from the body, as per the study. Per and polyfluoroalkyl substances or PFAS commonly known as forever chemicals are used to make a variety of everyday use products such as non-stick cookware, cosmetics, stain-resistant fabrics, firefighting foams, food packaging and waterproof clothing. Previous studies have shown that beta-glucan fibre molecules found in oats, barley and rye can bind to PFAS in the digestive system. Now, the latest study published in Environmental Health has found that a dietary supplement that has beta-glucan fibre could significantly reduce PFAS levels in the body. The focused study Image credits: Getty Images Researchers recruited 72 Canadian men aged 18 to 65 with detectable levels of PFAS in their blood and fed 42 of them a diet supplement of 1gm of oat beta-glucan, a type of soluble gel-fibre, before every mealtime, which is when the body produces most bile. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like This Wrinkle Cream Keeps Selling Out At Costco (Find Out Why) The Skincare Magazine Undo The remaining 30 participants were fed a placebo made of rice. 'Serum samples were collected from 72 participants in 2019-2020 at baseline and after four weeks of the intervention and were analysed for 17 PFASs,' stated the study. After 4 weeks, researchers found a nearly 10% drop in two of the most dangerous PFAS types in people who consumed the oat fibre supplement. These two PFAS, namely PFOA and PFOS are present in drinking water, food packaging and cosmetics and can build up in the body over time. These remain in the environment for hundreds of years and are linked to health conditions such as decreased fertility, higher risk of some cancers and developmental delays in children. Scientists and researchers have been looking for ways to remove these from the body and the environment to degrade them into harmless compounds. 'Despite the growing concerns about the toxicity of PFAS, specific interventions to reduce PFAS levels in the body are limited,' the study notes. 'Current clinical treatments to reduce PFAS body burden are minimal.' More research is required Although the results from this study are modest, scientists claim the findings offer a first step to forming a dietary intervention for removing PFAS from the body. 'Results from this pilot analysis suggest a potentially practical and feasible intervention that may reduce human body burdens for some PFASs,' they said. 'However, studies utilising a larger sample with a broader range of serum concentrations, longer intervention period and clinically relevant fibre intakes are needed to determine the efficacy of using gel-forming dietary fibres to increase PFAS excretion,' they added.
