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.

Exercise is good for the heart. That part is not in question. But on the occasion of World Heart Day, doctors say the way you exercise, and how suddenly you start, can matter just as much as whether you exercise at all.

The Weekend Warrior Problem

A lot of us live sedentary weekdays and then try to make up for it with one hard gym, swimming or sports session over the weekend. Dr Dhirendra Singhania, Director of Interventional Cardiology at Yashoda Medicity, says this pattern puts real strain on the body. "In an untrained person, a sudden switch to a much increased load in terms of time or intensity of training is a huge physiological stress on the heart," he told Health and Me.

Dr Ajeet Singh, Senior Consultant and Head of Cardiology at ShardaCare Healthcity, describes the same risk from the other direction. "Stepping into a sedentary lifestyle with a sudden burst of extreme activity, and vice versa, can strain the heart," he told Health and Me. Weekend sport, after a week of sitting, is one of the most common triggers.

What the Research Shows

Medical literature backs this up. New England Journal of Medicine study found that people who exercised regularly were far better protected against a heart attack being triggered by sudden exertion than those who rarely worked out. Research published in Circulation notes that the least fit individuals face the greatest risk during sudden physical effort. Doctors describe this as a fitness "buffer". A trained heart handles a sharp rise in oxygen demand and blood pressure far better than an untrained one.

This doesn't mean irregular exercise is pointless. A large 2023 study in JAMA, using activity-tracker data from close to 90,000 people, found that "weekend warriors" who packed their exercise into one or two days had a similarly lower cardiovascular risk to people who spread activity evenly through the week. The catch, researchers noted, is that this benefit shows up in people who are already getting regular activity in some form. Suddenly forcing an untrained body into a high-intensity session is a different scenario altogether.

Who Should Be Extra Careful

Both doctors agree that people with undiagnosed heart problems, high blood pressure, high cholesterol, diabetes or a family history of heart disease need to be more cautious. Dr Singh says this doesn't mean exercise should be avoided. It simply has to match "age, fitness level, and overall health and medical history." Dr Singhania advises anyone with existing heart disease or risk factors to consult their doctor before starting intense activity.

Warning Signs to Watch For

Both experts point to the same red flags. Chest pain or pressure, unusual breathlessness, dizziness, a racing heart, or simply feeling off during exercise. Dr Singhania lists "angina, unusual breathlessness, pre-syncope, syncope and palpitations" as symptoms that should never be ignored.

The advice from both doctors is simple. Warm up. Build intensity gradually. Cool down. Stay hydrated. And if something feels wrong mid-workout, stop and consult a doctor rather than trying to push through the discomfort.

Weight-loss drugs like Zepbound and Mounjaro work by suppressing appetite and making the user feel less hungry, reducing how much they eat. But a new study suggests tirzepatide, the active ingredient in both drugs, it could help the body use more energy by activating brown fat.

The finding primarily comes from mice, not humans, so it is too early to say that tirzepatide can directly increase the number of calories burned in users.

The study, led by researchers at the University of Barcelona and published in Biomedicine, looked at how tirzepatide affects different types of fat tissue.

How Does Tirzepatide Usually Help With Weight Loss?

Tirzepatide works by mimicking two hormones, GIP and GLP-1, which are involved in appetite, food intake and blood sugar regulation.

One of its major effects is reducing appetite, which can help people consume fewer calories. Research has already shown that tirzepatide can substantially reduce energy intake compared to placebo.

But researchers wanted to know whether there was something else happening inside the body that could not simply be explained by eating less, which led them to brown fat.

What Is Brown Fat?

Most of us are familiar with white fat, which stores excess energy. Brown fat is brown adipose tissue. It is known for using energy and producing heat. It contains mitochondria that allow it to burn fuel.

The researchers gave obese mice tirzepatide and compared them to mice that were not given the drug but consumed the same amount of food. This development allowed the scientists to separate the effects of the drug from the effects of simply eating fewer calories. They identified that tirzepatide activated brown adipose tissue.

According to the researchers, this was linked with a greater capacity to use metabolic energy and with the production of signalling molecules called batokines, which may have beneficial effects on metabolism.

Could Mounjaro And Zepbound Also Burn Calories?

It’s a possibility but it has not yet been proven in humans. The study suggests that tirzepatide can activate a biological pathway involved in energy burning. That is different from proving that Mounjaro or Zepbound can burn calories as well.

This distinction is important because headlines about “boosting metabolism” can make the effect sound much larger or more established than the evidence currently allows.

For years, scientists have been exploring whether activating brown fat could help find another way of tackling obesity. Most weight-loss strategies focus heavily on reducing how much energy enters the body. Activating brown fat offers another way of increasing how much energy the body uses.

Previous attempts to stimulate brown fat pharmacologically have run into problems, particularly due to unforeseen cardiovascular effects.

The University of Barcelona researchers say tirzepatide’s known cardiovascular benefits make its brown-fat activation particularly interesting, although this finding itself still needs to be confirmed in huma Tirzepatide ns.

Tirzepatide already has several effects on the body through its GIP and GLP-1 activity. Reduced appetite and food intake remain important mechanisms behind its weight-loss effects. The new study suggests that changes in fat tissue and energy metabolism could add scope layer to the drug’s effects.

But it would be premature to conclude that brown-fat activation is responsible for a the weight loss seen with tirzepatide in people.

Hollywood star Sylvester Stallone recently revealed that building the body to play Rocky Balboa in his Oscar-winning film Rocky came at a health cost.

The 80-year-old actor has revealed that his obsession with achieving an extremely lean, muscular physique while making the Rocky films became so intense that he developed bulimia and used anabolic steroids. Speaking to The New York Times, Stallone said he reached 2.6% body fat while filming Rocky III and described his relationship with his body at the time as an “obsession.”

He also said he used steroids in cycles of roughly six weeks on and six weeks off, while revealing that the approach eventually took a “terrible toll” on his body.

Stallone's admission admission offers a glimpse into the health risks that can come with the obsession of chasing an extremely muscular physique with very low body fat.

Stallone said, “It was my armor. I looked at Rocky: very smooth, very normal-looking guy. And then I said, I think the character would start to become a bit more vain. And then in ‘Rambo,’ you’re playing a warrior, so you’d be a little bit more animalistic. You wouldn’t be so smooth,” he said. “So I started to think: Design your body like a jaguar, a cat. Not big like Arnold, but more feral and aggressive and very limber and athletic.”

He added, “It got to the point where I became bulimic,” he said. “I got down to 2.6 percent body fat when I was doing ‘Rocky III,’ and I couldn’t hold anything down. Or I didn’t want to keep it down because I became so obsessed with staying at that point of fitness, literally an obsessive body-worship kind of thing.”

What Is Bulimia?

Bulimia nervosa is an eating disorder involving recurrent episodes of binge eating is followed by erratic actions intended to compensate for the food consumed. For example, after binge-eating, one may purge, meaning self-induced vomiting, fasting, excessive exercise or misuse of laxatives. The goal is not simply wanting to lose weight.

Repeated purging can lead to dehydration and dangerous imbalance of essential electrolytes, particularly involving potassium. These changes can interfere with the heart's electrical activity and, in severe cases, lead to life-threatening abnormal heart rhythms.

Bulimia can also lead to acid reflux, gastrointestinal problems, chronic throat irritation, swollen salivary glands and erosion of tooth enamel.

Extremely Low Body Fat Is Risky

Stallone's said that he had reached a body-fat level of 2.6% which is an extraordinarily low number. However, a body-fat percentage alone cannot diagnose an eating disorder. It is ascertained by how someone got to that number and what happens to the body in the process.

Severe restriction on eating habits and excessive exercise can leave the body deprived of adequate energy, electrolytes, and nutrients.

Eating disorders can affect the heart, bones, muscles, reproductive system and other organs, and they can occur in people belonging to different weight groups.

In Stallone's case, he said he was unable or unwilling to keep food down while remaining intensely focused on maintaining his physique.

Risks Of Anabolic Steroids

Anabolic-androgenic steroids are synthetic substances related to testosterone. They can increase muscle mass and strength, but using them without medical supervision can have adverse effects on different organs.

Misuse of these steroids can lead to high blood pressure, abnormal cholesterol levels, heart problems, liver disease and kidney damage. It can also affect fertility and reproductive hormones. Changes in mood, irritability and aggressive behaviour have also been seen.

The cardiovascular effects are particularly alarming as long-term anabolic steroid misuse can lead to to changes in heart structure and function as well as increased cardiovascular risk.

Stallone has previously spoken about the physical consequences of his decades-long approach to fitness, saying he has undergone nine back operations, two shoulder operations and three neck fusions.

He has also said that playing a heavier, physically less imposing character in Cop Land helped him feel liberated from the pressure to maintain his action-star physique.
