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

We spend a lot of time worrying about skin, hair, weight, and even gut health, but we often ignore our joints.

We depend on our joints for every step, squat, staircase climb, and grocery run. Knees alone absorb forces several times body weight during ordinary activities. Globally, an estimated 595 million people were living with osteoarthritis in 2020, roughly 1 in 13 people on the planet, and a 132% increase in total cases since 1990. Alarmingly, many of us are making lifestyle choices that place unnecessary stress on our joints long before we hit our forties or fifties.

While ageing is the main cause of joint pain, stiffness, and reduced mobility, these issues are increasingly showing up in younger adults, too.

Here are five common habits that could be quietly working against your joint health.

Mistake #1: Improper Footwear Choices

It is really important that your footwear has adequate cushioning or support. The impact of every step travels upward through your ankles, knees, hips, and lower back. Your footwear plays the role of a shock absorber. Gradually, repetitive stress placed on your feet contributes to discomfort, especially if you spend long hours standing, walking, commuting, or exercising.

It is important to choose footwear that suits your activity level. If you exercise regularly, make sure your shoes match the type of movement you are doing, and replace them once the support wears out.

Mistake #2: Going All-In on Cardio and Calisthenics Without Guidance

Social media has made fitness more accessible than ever. It's also convinced a lot of people that every workout needs to be intense. High-volume jumping drills, excessive running, deep-impact movements, and advanced calisthenics performed without proper progression can overload joints, tendons, and ligaments. Unlike muscle, the cartilage cushioning your joints has no blood supply and very limited ability to repair itself once damaged, which is why overuse injuries can have lasting consequences rather than simply healing with time.

Joint problems are often linked to poor exercise choices, but inadequate recovery can also impact them. Not giving enough rest, nutrition, or recovery time causes tissues to suffer due to the stress being placed on them, leading to aches, pains, and overuse injuries.

Focus on gradual progression, proper technique, adequate recovery, and a balanced routine that includes strength training, mobility work, and rest days.

Mistake #3: Constantly Cracking Your Knuckles and Joints

While knuckle cracking is not directly responsible for arthritis, habitual and forceful joint manipulation can irritate surrounding soft tissues and become a repetitive stress habit over time.

Medical attention may be required if cracking is accompanied by pain, swelling, locking, or instability.

Mistake #4: Ignoring the Nutrition Side of Joint Health

Many diets fall short on two nutrients that matter a lot for musculoskeletal health: calcium and vitamin D. Calcium builds and maintains bone strength. Vitamin D helps the body absorb and use it. Inadequate intake of either results in weaker bones, in turn causing poor joint health. Excess body weight adds another layer to this. Not just as an added mechanical load on the joints, but because fat tissue actively releases inflammatory compounds that can accelerate cartilage breakdown. This makes joint health a metabolic issue, not just a structural one.

Calcium sources include milk, yoghurt, paneer, cheese, ragi, sesame seeds, tofu, almonds, and green leafy vegetables. Vitamin D sources include safe sunlight exposure, egg yolks, fatty fish, and fortified dairy products.

Mistake #5: Sitting for Most of the Day

Long hours at a desk, extended scrolling sessions, and prolonged sitting can weaken the muscles that support the joints. This leads to stiffness, poor posture, and mobility issues. Inactivity can also set off a compounding cycle: as joints become less stable and more uncomfortable, people tend to move less to avoid pain, which leads to further muscle weakening, reduced joint support, and faster deterioration over time. Standing up regularly, taking walking breaks, stretching between meetings, and using the stairs keep joints mobile and well-supported.

The Bottom Line

Joint health is the result of small decisions made consistently over time: the shoes you wear, how you exercise, what you eat, and how much you move. Most joint problems don't appear overnight, and many of the habits that lead to them can be corrected before they become long-term issues.

A new study has uncovered how physical activity can help aging muscles repair themselves, explaining why regular exercise remains one of the most powerful tools for healthy aging physiologically.

Exercise Can Help Reverse Muscle Aging: Study

Researchers from Duke-NUS Medical School, working with collaborators from Singapore General Hospital and Cardiff University, found that exercise retains and restores a natural cellular repair system that usually weakens with age.

Their findings, published in the Proceedings of the National Academy of Sciences (PNAS), identify a gene called DEAF1 as a muscle aging element, suggesting it could become useful in therapies for preventing age-related muscle loss.

About The Study

Muscles are essential for regulating metabolism, blood sugar levels, and supporting overall health. However, muscle strength begins to decline as you age, increasing the risk of falls, fractures, and slower recovery from illness or injury.

A cellular growth pathway called mTORC1 plays an important role in maintaining healthy muscles by regulating protein production. But in aging muscles, this pathway becomes overworked.

According to the study, DEAF1 levels increase as muscles age, driving excessive mTORC1 activity and disrupting the balance between building new proteins and clearing away damaged ones. This accelerates muscle deterioration.

Under normal conditions, DEAF1 is kept under control by proteins known as FOXO. However, FOXO activity naturally declines with age, allowing DEAF1 levels to rise unchecked and reduce the muscle's ability to repair itself.

Exercise Restores Muscle Health

Exercise can reverse this imbalance significantly if the muscles are still optimal and responsive.

Assistant Professor Tang Hong-Wen, lead author of the study from Duke-NUS Medical School said, “Exercise can reverse this process, correcting the imbalance. Physical activity activates certain proteins which lower DEAF1 levels, bringing the growth pathway back into balance. This allows aging muscles to clear out damaged proteins, rebuild themselves properly, and help them stay stronger and more resilient.”

The researchers believe the results extend beyond normal aging. DEAF1 also affects muscle stem cells, which are responsible for repairing damaged tissue but naturally become less effective with age.

Targeting the gene could potentially improve muscle recovery after surgery, illness, or conditions such as cancer, particularly in people who are unable to exercise.

“Exercise tells muscles to 'clean up and reset.' Lowering DEAF1 helps older muscles regain strength and balance, almost like hitting the rewind button. With millions of older adults at risk of muscle decline, understanding DEAF1 could lead to new ways to protect muscles and improve quality of life,” said Priscillia Choy Sze Mun, first author of the study.

Healthy muscles are essential for far more than movement. They help maintain balance, support metabolism, regulate blood sugar, and enable people to stay independent as they age.

The study also confirms that regular exercise not only strengthens muscles but also helps retain their ability to repair themselves at the cellular level. In short, staying physically active remains one of the most effective ways to protect muscle health and promote healthy aging.

Cardio has long been the gold standard for heart health, while yoga is often seen as a way to enhance flexibility or relieve stress. This has led to a debate over which is better for overall health.

On the 12th International Yoga Day 2026, HealthandMe turned to experts to understand the ultimate regimen for heart and overall health.

Is the Debate Warranted?

Dr. V Mohan, Chairman of Dr. Mohan's Diabetes Specialities Centre and Madras Diabetes Research Foundation, told HealthandMe that yoga and cardio exercises provide a lot of health benefits.

Rather than viewing yoga and cardio as competing options, they should be seen as complementary forms of exercise, he said.

Dr. Sudhir Kumar, Senior Consultant Neurologist at the Institute of Neurosciences, Apollo Hospitals, echoed a similar view, noting that the debate between yoga and cardio is often framed incorrectly because they are not competing interventions and offer complementary benefits.

Yoga vs Cardio

The experts explained that both forms of exercise work in different ways.

Brisk walking, running, cycling, jogging, and swimming are cardio exercises that help improve cardiovascular health, insulin sensitivity, and calorie burning.

On the other hand, yoga focuses mainly on balance, strength, flexibility, stress management, and emotional well-being.

Dr Sudhir told HealthandMe that aerobic exercise, such as brisk walking, running, cycling, or swimming, has the strongest evidence for improving cardiorespiratory fitness (VO₂ max), reducing cardiovascular risk, enhancing insulin sensitivity, and lowering the risk of diabetes, heart attack, and stroke.

Dr Mohan added that yoga helps improve balance, strength, flexibility, stress management, and emotional well-being. Chronic stress can increase cortisol levels, and elevated cortisol levels can cause uncontrolled blood sugar levels and may contribute to weight gain. Yoga helps address these issues while improving overall quality of life.

What Is An Ideal Fitness Regimen?

Dr Mohan said an ideal fitness regimen should include both cardio exercises for metabolic and cardiovascular health, and yoga for stress management, boosting self-esteem, and long-term sustainability.

Dr Sudhir said that for overall health, neither should be viewed as a substitute for the other. Current scientific evidence supports a combination approach: regular aerobic exercise for heart and metabolic health, strength training for musculoskeletal health, and yoga for flexibility, recovery, and stress management.

"The best exercise is ultimately the one that is sustainable and becomes a lifelong habit," he said.

Both Have an Important Role

Vadodara-based cardiologist Dr Pruthvirajsinh Puwar, Consultant Interventional Cardiologist, shared that both play an important role.

"Cardio activities like walking, running, or cycling help strengthen the heart muscle, improve blood circulation, and control weight. Yoga, on the other hand, helps reduce stress, improve breathing, balance blood pressure, and calm the nervous system," he said in an Instagram post.

He suggested combining both — regular physical activity for strength and yoga for balance and relaxation.

How Yoga Benefits Heart Health

Several studies have claimed the benefits of yoga for reducing the risk of hypertension, insulin resistance, and dyslipidemia, which are key to reducing health risks as well as improving overall health.

One of yoga's most significant benefits for heart health is its ability to promote relaxation of both the body and mind. Emotional stress triggers the release of hormones such as cortisol and adrenaline, which can constrict blood vessels and raise blood pressure. Through controlled breathing and mindfulness, yoga can help counter these stress-related effects.

Feelings of anxiety and depression are also common after major cardiac events, including a heart attack, bypass surgery, or a diagnosis of heart disease. When incorporated into a broader treatment plan, yoga can support stress management and emotional well-being during recovery.
