When it comes to the health of an obese person, suddenly everyone becomes a doctor, a health coach and motivational speaker. Most people believe all the person has to do is exercise more and eat less, but that is not the case at all. While you may not believe them, certain details like what you ate before exercising and the time of day you exercise at can affect a person’s health, it certainly plays a role! Fitness is never a linear process for anyone. While some people see a big difference in the first few weeks, other may not see a difference even months later. While these things may be discouraging, you have to remember that your health does not stop getting better every day, even if it is not apparent to the naked eye.

A new research published in Diabetes Care suggests that people with obesity, especially those who also have type 2 diabetes, might get the most health benefits if they exercise between 6 p.m. and midnight. The study found that people who were most active at night had a lower risk of heart problems and dying early compared to those who exercised at other times. This is interesting, but we need more research to be sure about it.

How The Time You Exercise Affects Your Health

Other studies have suggested that exercising at night is good for people with type 2 diabetes. This new research wanted to learn more about it and see how the time of your workout affects your health in the long run. Researchers looked at almost 30,000 people with obesity, some also had type 2 diabetes. People wore devices that tracked their activity for a week, so the researchers could see when they were most active. After watching these people for almost eight years, they found that the people who did most of their exercise at night had the lowest risk of health problems, like heart disease. While exercising at night seemed best, exercising at any time was better than not exercising at all.

Morning vs. Night Workouts: Which is Better?

The study suggests that nighttime workouts might be best for people with obesity and type 2 diabetes. But experts say the most important thing is to exercise whenever you can. Nighttime might be better, but it's not always possible for everyone. People are busy with work, family, and other things. So, the main message is: any exercise is good, no matter when you do it. Don't let worrying about the "perfect time" stop you from being active. Adults should try to get about 2 and a half hours of moderate exercise each week, plus some strength training. If someone with obesity or type 2 diabetes can exercise between 6 p.m. and midnight, they might want to try it. But everyone's different. Exercise should be something you can do regularly, not something that's a struggle. If nights don't work, that's okay! Even short bits of activity during the day, like walking at lunch, are helpful. The best workout is the one you'll actually do.

Things to Keep in Mind Before You Start Working Out

If you're new to exercise or haven't been active for a while, start slowly and gradually do more. It's a good idea to work with a trainer or a friend who can help you and make sure you're being safe. This is especially important for people who are overweight, have obesity, or type 2 diabetes, because they might have other health problems that exercise can affect. Pay attention to your body and stop if you feel dizzy, have chest pain, or just don't feel good. Always talk to your doctor before starting a new workout plan, especially if you have any health problems. They can give you advice that's right for you.

Timing of Moderate to Vigorous Physical Activity, Mortality, Cardiovascular Disease, and Microvascular Disease in Adults With Obesity

If you believe only gym workouts matter, you might be mistaken. While gyms offer a structured space to exercise, busy schedules often lead many to skip workouts—and feel guilty about it.

However, a new study suggests that even short bursts of vigorous everyday activity—such as running to catch a bus or climbing stairs quickly—can significantly reduce the risk of several major diseases and even lower the risk of death.

The research, based on nearly 96,000 people and published in the European Heart Journal, found that just a few minutes of intense activity each day was linked to a lower risk of:

• Major cardiovascular disease
• Irregular heartbeat
• Type 2 Diabetes
• Immune-mediated inflammatory diseases
• Liver disease
• Chronic respiratory diseases
• Chronic kidney disease
• Dementia

“We know that physical activity reduces the risk of chronic disease and premature death, and there is growing evidence that vigorous activity provides greater health benefits per minute than moderate activity,” said Minxue Shen from the Xiangya School of Public Health, Central South University, China.

Longer Workouts or Intense Bursts?

To explore whether exercising more intensely offers greater benefits than simply exercising longer, the researchers followed 96,408 participants for seven years.

Each person wore a wrist-based accelerometer to track movement, including short bursts of activity often overlooked.

The findings showed that compared to those who did no vigorous activity, participants with the highest levels had:

• 63 percent lower risk of dementia
• 60 percent lower risk of type 2 diabetes
• 46 percent lower risk of death

“Our findings suggest that adding short bursts of activity that make you slightly breathless—like climbing stairs quickly or walking briskly between tasks—can have substantial health benefits,” Shen said.

“Even 15–20 minutes per week, just a few minutes a day, can make a meaningful difference,” the Professor added.

Is Vigorous Activity Safe for Everyone?

The World Health Organization (WHO) recommends that adults (18–64) perform at least 150–300 minutes of moderate-intensity aerobic physical activity, or 75–150 minutes of vigorous-intensity activity per week.

The new study suggests that intensity also plays a key role—and may vary depending on the disease being prevented.

The researchers noted that these findings could help shape more personalised exercise recommendations in the future. However, they cautioned that vigorous activity may not be suitable for everyone, particularly:

• Older adults
• People with certain underlying medical conditions.

IPL 2026 is back, and for fans of cricket, it is the most amazing and eagerly awaited time of the year. Eight exceptional teams, an incredible line-up of cricketing sensations from all over the world, and an unforgettable clash of titans — IPL deserves all the hype it gets. And after last night's incredible battle between Kolkata Knight Riders and Mumbai Indians, former captain Rohit Sharma also deserves all the hype he is getting. Not only did the Hitman score his fastest IPL 50, but he also managed to impress everyone with his transformation. Nita Ambani, Chairperson and founder of the Reliance Foundation and Dhirubhai Ambani International School, and a director of Reliance Industries (owner of the Mumbai Indians team too), was awestruck to see a fitter version of Sharma.

When Nita Ambani did not recognise Rohit Sharma

In a recent video shared on the Instagram page of Mumbai Indians, Nita Ambani is seen meeting the squad as they were training ahead of the 2026 IPL. As she encounters Sharma, she says, "My God, Rohit, I didn’t recognise you! You look like a young boy."

Rohit Sharma, now 38, will be turning 39 on April 30, but to a fan's eye, he seems to be ageing in reverse. On May 7, 2025, Sharma announced his retirement from Test cricket. Earlier in 2024, he announced his retirement from T20Is after the 2024 World Cup win. Since then, he has focused primarily on ODIs and, as it turns out, on becoming a fitter version of his current self.

A fitter Rohit Sharma since retirement

Rohit Sharma smashed an impressive 78 off 38 balls in last night's match against KKR, and perhaps his success can be credited to his recent transformation. His physical transformation took place ahead of the Vijay Hazare Trophy, and he lost an impressive 11 kilos before returning to the game. But what his fans loved most is that he was never really lagging because of the extra weight — he was always fit, quick and proactive, but now he is a lot leaner on the outside. How did the former skipper achieve this goal? Let’s find out:

1. Hydration: For Sharma, fitness has to start with hydration, and this involves drinking plenty of water throughout the day in various forms — protein shakes, green tea and carrot juice.
2. High-protein meals: According to TheHealthSite, Sharma switched to a high-protein diet, which is one of the most important steps in a weight-loss journey. This means foods like eggs, oats, legumes, millet rotis, brown rice, grilled chicken and salads dominated his diet routine.
3. Workout regime: A workout regimen need not be about the kind of exercise one does, but also the timings. Reports suggest that Sharma kick-started his days with 30 minutes of cycling, followed by a core workout. And the best part — he relied on morning workouts for optimal results, as during the early hours of the day, scientists say it is the best time to break a sweat.

Cardio workouts like interval training, running and cycling help build stamina and endurance — these help ensure peak performance during stressful matches.

Long considered a standard tool for assessing body weight, Body Mass Index (BMI) may not be as reliable as once believed. A new study shows that relying on BMI can incorrectly classify people as overweight or obese.

When a team of Italian researchers used the gold standard technique of dual-energy X-ray absorptiometry (DXA) to measure body fat in the general population, they found that the traditional WHO-approved BMI classification system misidentified a significant number of people as having overweight or obesity.

How Is The BMI Wrong?

A total of 1,351 adults of mixed gender aged between 18 and 98 years were checked for their body weight using the DXA system.

The results, published in the journal Nutrients, revealed that more than one-third (34 percent) of those with obesity defined by BMI had been misclassified and should be in the overweight category.

For those with an overweight BMI, DXA showed that more than half – 53 percent – had been misclassified – three quarters of those misclassified fall into the normal weight category, while the other quarter should have been classified as having obesity.

The DXA analysis found that the prevalence of overweight and obesity across the cohort was around 37 percent overall (23.4 percent overweight, and 13.2 percent obesity, compared to 26.2 percent and 14.1 percent with BMI).

“In the past few years, there has been a lot of criticism of the BMI system due to its inability to accurately capture body fat percentage or distribution, to correctly categorise weight status based on adiposity,” said Professor Marwan El Ghoch, of the Department of Biomedical, Metabolic and Neural Sciences, University of Modena and Reggio Emilia, Modena, Italy.

Despite these concerns, BMI as a weight classification system continues to be used in the general population in primary healthcare (i.e., general practitioners) and non-clinical (i.e., policy and health insurance) settings, he added.

The researchers urged revising public health guidelines to consider combining direct body composition or their surrogate measures, such as skinfold measurement or body circumference, with the waist-to-height ratio, with BMI, while assessing weight status in the general population.

Waist-to-Height Ratio May Be More Accurate: The India Story

In January 2025, India revamped its obesity guidelines, and the new approach focused on abdominal obesity and comorbid diseases, rather than just BMI.

According to the redefining team, it was essential to move beyond BMI-only approaches to tackle the ever-growing number of people related to other major health risks. They stated that while BMI can be a screening tool, obesity must be defined by body fat.

“BMI should be used for screening purposes, but obesity should be confirmed ideally by a measure of body fat wherever feasible, or another measure such as waist circumference, WHR, or Waist-to-height ratio,” Dr. Naval Vikram, Professor of Medicine, at AIIMS, New Delhi, was quoted as saying to IANS at the time.

What Do The New Guidelines Say

It recognizes abdominal fat — closely linked to insulin resistance — as a key factor in the diagnosis. It integrates the presence of comorbidities — such as diabetes and cardiovascular disease — into the diagnostic process.

The revised guidelines also introduce a two-stage classification system, addressing both generalized and abdominal obesity.

Stage 1 Obesity: Increased adiposity (BMI > 23 kg/m²) without apparent effects on organ functions or routine daily activities.

Stage 2 Obesity: Advanced state of obesity with increased BMI more than 23 kg/2, and abdominal adiposity; excess Waist Circumference or Waist-to-Height Ratio.
