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

While exercise is good for the body and mind, it can have special benefits for the liver — a key organ that filters blood, breaks down food, stores energy, and keeps the human body in balance.

In recent years, there has been a significant increase in young patients presenting with poor liver health and related conditions, such as fatty liver and liver fibrosis, among others.

A recent study published in The Lancet Gastroenterology & Hepatology journal showed that the Metabolically Dysfunctional-Associated Steatotic Liver Disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), affected 1.3 billion people around the globe in 2023.

India has also shown a sharp rise in MASLD prevalence, up 23.19 per cent from 1990 to 2023. India’s age-standardized MASLD prevalence rate rose from 10,191 per 100,000 in 1990 to 12,555 per 100,000 in 2023.

The findings show that the spike is increasingly driven by rising metabolic risk factors, including high blood sugar and obesity.

Amid the growing burden, hepatologist Dr Cyriac Abby Philips noted that “the best friend of the liver is muscle”. In a post on social media platform X, Dr Philips, popularly known as Liverdoc, added that “liver listens to your muscles” and shared nine exercises, all backed by clinical trials, that can be included in a daily routine to help boost liver health.

Brisk walking:

According to Dr Philips, brisk walking is the most accessible liver medicine. He noted that "150 min per week cuts liver fat by more than 30 per cent on MRI”. Citing a UK Biobank study of 91,000 people, he added that every extra 1,000 daily steps can lower the risk of developing fatty liver by about 12 per cent.

Moderate-intensity cardio (MICT):

This includes steady jogging, cycling, or swimming at a "can talk, can't sing" pace. Dr Philips stated that 30–45 minutes of MICT exercises for 3–5 days every week for 12 weeks can help reduce liver fat by 2–4 per cent (absolute). It can also significantly lower liver inflammation (enzyme levels), even without weight loss.

High-intensity interval training (HIIT)

This includes short hard bursts, like burpees, jumping jacks, etc. He recommended four minutes of these exercises “at 85–95 per cent max heart rate”.

Repeating the exercise 4 times a day can “cut liver fat by 16–37 per cent, improve heart function,” in 12 weeks, the Liverdoc said. He added that the exercise regimen “matches steady cardio in half the time”.

Sprint interval training (SIT)

SITs are shorter and harder under 15-minute sessions of squat punches, knee hovers, and chair squats. “Six weeks of these can reduce intrahepatic triglycerides by 12 per cent and visceral fat by 17 per cent in men with fatty liver (MASLD),” said Dr Philips, adding that it gives the “biggest liver benefits for the smallest time spent”.

Resistance/strength training

This includes weights or bodyweight, such as squats, presses, rows, and pulldowns. Dr Philips recommended 3 sets of these exercises three times a week for about 40–45 min.

It can “reduce liver fat independent of weight loss, uniquely lowers liver enzyme, and is the single most important exercise for cirrhosis patients to prevent muscle loss (sarcopenia),” he said.

Combined aerobic + resistance

The Liverdoc stated that this combination is the gold standard for exercises. He noted that “network meta-analyses rank this combination as the number one for improving triglycerides, LDL, and total cholesterol in patients with fatty liver (MASLD) - better than either alone”.

Yoga (Hatha/ Surya Namaskar)

Dr Philips noted that classical yoga is not useful for liver health as it is not aerobic and vouched for the modernized versions.

“Eight to 12 weeks or 3 sessions/week of asanas like Surya Namaskar, Ardha Matsyendrasana, Paschimottanasana, Naukasana can help improve liver tests, insulin resistance, and fatty liver grade - especially in patients with type 2 diabetes plus fatty liver disease,” he said.

Pilates and core work

“Eight weeks of pilates can help reduce body weight, body fat, liver enzymes, and liver fat on ultrasound,” said Liverdoc. He called it a joint-friendly option for people who can't run or lift heavy.

Tai Chi / Qigong

The Chinese exercise is a low-impact mind-body movement. About 30–60 min of these three times a week can help “improve glucose control, insulin sensitivity, and balance/ stability, muscle tone," Dr. Philips said.

He noted that this form of exercise is “gentle enough for older patients, those with early decompensated cirrhosis, or people with poor cardiorespiratory fitness”.

Exercise In Cirrhosis

Dr Philips said that even advanced liver disease can respond well to exercise treatment.

Citing randomized trials, he stated that “combined aerobic plus resistance training cuts serious events (death, major complications) from 12.3 per cent to 5.6 per cent”. It also “prevents the muscle wasting that drives death events in cirrhosis patients”.

“Make physical activity your number one preference to maintain liver health and reduce liver disease,” Dr Philips said.

For many working professionals, going to the gym often feels like a luxury. Their days begin early and end late—rushing for buses and metros, juggling deadlines, presentations, meetings, and endless reports.

So when they are diagnosed with conditions like diabetes or high blood pressure, the most practical and affordable option left is walking. Another common step is cutting down on sugar in tea and coffee. While these are good starting points, these may not be enough.

Calling them "most frustrating", Dr. Sudhir Kumar, Neurologist at Apollo Hospital, Hyderabad noted that such "patients are losing a battle they think they are winning".

"Every day, I see patients with obesity, Type 2 Diabetes, or hypertension who tell me: 'I walk every morning, Doctor'. 'I do all the household work.' 'I have stopped adding sugar to my tea'," said Dr Kumar, in a post on social media platform X.

He also cited these as "dangerous health misconceptions", wherein the patients feel they have done their part, but "their blood work and body composition tell a different story".

Popularly known as the Hyderabad doctor on X, the noted neurologist shared some evidence-based reality of why "walking and quitting sugar" may not be enough.

Several studies have pointed out that walking or undertaking household chores is better than a sedentary behavior. However, neither can be a "substitute for strength training", Dr. Kumar said.

Although walking can burn a few calories, "strength training builds the 'engine' that burns glucose even while you sleep".

"If you are not lifting weights or doing resistance training at least twice a week, your insulin resistance will likely persist, regardless of your step count", he said.

Speaking to HealthandMe, Dr. Manisha Arora, Director - Internal Medicine at the CK Birla Hospital, Delhi, explained that cutting sugar and walking are good first steps, but they do not solve the problem of diabetes and high blood pressure.

"Insulin resistance, inflammation, and loss of muscle all contribute to these diseases. Light walking may help, but the intensity and duration of exercise are also important," he added.

What Is Strength Training?

Strength training exercises force muscles to contract against an external force, such as body weight, dumbbells, or bands. Common examples include

• squats,
• lunges,
• step-ups,
• push-ups,
• planks.

Strength training helps

• Decrease insulin resistance
• Lower blood pressure
• Improve cognitive function
• Reduce systemic inflammation
• Protect against neurodegenerative diseases like Alzheimer’s.

Focus On Protein Leverage

Dr. Kumar further mentioned the diet trap that most people fall into, that is., cutting out sweets and sugar, while loading up the plate with carbohydrate-rich foods such as rice, roti, and poha — 80 percent — and zero protein content.

"Refined carbohydrates (even without added sugar) spike insulin similarly to sugar," he said, calling "no sugar as the bare minimum".

The doctor noted that "a protein-deficient diet can lead to muscle loss and increase hunger".

To lower blood sugar levels, the experts urged to cut down on other foods, such as

• refined carbohydrates,
• processed foods,
• low-fiber foods.

"Focus on protein leverage. Prioritize 1.2g to 1.5g of protein per kg of body weight. When you hit your protein goals, your craving for carbs naturally drops," Dr. Kumar said.

To see the real change in blood sugar and BP levels, he advised people to "add two days of resistance training (bodyweight, bands, or weights)", instead of "just walking",.

The neurologist also recommended "starting the meal with protein paneer, eggs, sprouts, lean meat, and to eat carbs last, and in smaller portions".

In addition, a diet high in protein and fiber from whole grains, fruits, and nuts can also help control blood sugar levels.

"The most successful approach to controlling blood sugar results from combining aerobic exercise with strength training, along with balanced nutrition," said Dr Arora.

We often assume that having a “normal weight” automatically means being healthy. While body weight is an important parameter, it represents only a small part of overall health. True health is far more complex than what a number on the weighing scale can convey.

Understanding The Limitations Of BMI

Body Mass Index (BMI) is widely used to classify individuals based on their weight relative to height. However, it does not differentiate between fat and muscle. As a result, someone may fall within the normal BMI range yet still have high body fat and low muscle mass, a condition known as “normal weight obesity.” Such individuals may appear healthy but remain at risk for metabolic disorders.

Why Is Body Composition Important?

Body composition analysis offers deeper insight by evaluating fat, muscle mass, and their distribution in the body. A combination of low muscle mass and excess body fat, especially around internal organs, can increase disease risk, even when overall weight appears normal.

The role of fat distribution:

All body fat is not the same. Where fat is stored matters significantly. The waist-to-height ratio is now considered a more reliable indicator than BMI, as it reflects fat distribution. A ratio above 0.5 is associated with a higher risk of conditions such as type 2 diabetes, cardiovascular diseases, and even increased mortality.

Looking beyond numbers:

Health cannot be defined by numbers alone. Factors like physical activity, nutrition, stress levels, and sleep quality play an equally critical role. Even individuals with a normal weight can experience poor metabolic health due to inadequate sleep or chronic stress.

The bigger perspective:

Good health is not just about appearance or weight, it is the result of multiple factors working together. It reflects a balance between internal processes and external lifestyle choices.

In essence, being of normal weight does not necessarily mean being healthy. To truly stay well, it is important to look beyond weight and consider the broader picture of health.
