The global obesity epidemic, affecting over one billion people worldwide, is largely driven by eating behaviors. Appetite, influenced by both intrinsic and environmental factors, plays a crucial role in weight management. A recent study how exercise affects appetite perception in obese males, shedding light on the physiological mechanisms behind hunger suppression post-exercise.
While exercise is well-known for its benefits in weight management, its direct impact on appetite control has remained a subject of debate. Appetite is regulated by a complex network of gastrointestinal and neurohormonal signals, including hormones like ghrelin, leptin, interleukin 6 (IL-6), and neuropeptide Y (NPY). These hormones influence hunger levels, satiety, and energy balance.
The study published in Physiological Reports examines investigated how moderate continuous aerobic exercise (MICE) alters these hormone levels in obese men, ultimately affecting their hunger perception. The findings reveal that certain myokines and cytokines shift dynamically post-exercise, potentially reducing appetite and offering a promising strategy for weight management.
The study found that after exercise, there was a significant increase in IL-6 and irisin levels in the exercise group compared to those who remained sedentary. These elevated concentrations persisted for an hour after working out. IL-6 has been associated with regulating metabolism and enhancing fat oxidation, while irisin plays a role in converting white fat into more metabolically active brown fat.
Conversely, the study reported a decrease in neuropeptide Y (NPY) levels, a key neurotransmitter responsible for stimulating appetite. The decline in NPY levels post-exercise suggests a temporary suppression of hunger, supporting the idea that exercise can curb cravings. However, the study did not observe significant changes in IL-7 or leptin levels, two other hormones involved in appetite regulation.
Ghrelin, often called the “hunger hormone,” stimulates appetite by increasing activity in specific areas of the brain. Individuals with higher ghrelin levels generally find it harder to lose weight because their bodies signal hunger more frequently.
Research suggests that dieting can lead to an increase in ghrelin levels, making weight loss challenging. Certain medical conditions, such as Hashimoto’s thyroiditis, Prader-Willi syndrome, anorexia nervosa, and bulimia nervosa, are also linked to elevated ghrelin levels, complicating appetite regulation further.
While exercise has clear benefits, the findings should be interpreted with caution. He pointed out that the study had a small sample size, making it difficult to draw definitive conclusions.
Moreover, he highlighted the challenges faced by obese individuals in maintaining an intensive exercise routine. While exercise-induced appetite suppression is promising, consistently engaging in high-intensity workouts may be unrealistic for those who struggle with mobility or fitness levels. More extensive studies are needed to determine the optimal exercise duration and intensity for effective appetite suppression.
Besides exercise, there are several strategies individuals can use to naturally suppress their appetite and improve satiety:
Increase Protein Intake: Protein-rich foods, such as lean meats, legumes, and dairy, promote feelings of fullness and reduce hunger.
Stay Hydrated: Drinking water before meals can help control portion sizes and prevent overeating.
Opt for Fiber-Rich Foods: Whole grains, vegetables, and fruits high in fiber take longer to digest, keeping you full for longer.
Reduce Simple Carbohydrates and Sugars: Simple carbs and sugars cause rapid spikes and crashes in blood sugar levels, leading to increased hunger.
Prioritize Sleep: Poor sleep disrupts hunger-regulating hormones, making it harder to control cravings.
Manage Stress: Chronic stress increases cortisol levels, which can lead to overeating and weight gain.
The study’s findings indicate that moderate exercise can temporarily suppress appetite by altering key hormones. While more research is needed to refine the details—such as optimal workout duration and intensity—this insight adds to the growing body of evidence supporting exercise as a tool for appetite regulation and weight management.
For individuals looking to curb cravings and maintain a healthy weight, incorporating a well-balanced diet alongside regular exercise remains the most sustainable approach. Future studies focusing on larger populations and long-term effects could provide deeper insights into how exercise can be optimized for appetite control, making it an effective strategy in combating obesity.
Exercise alone is not a magic solution for weight loss, but its impact on appetite hormones presents a promising avenue for managing hunger and energy balance. As research continues to evolve, it becomes increasingly clear that integrating physical activity with mindful eating habits can play a vital role in achieving and maintaining a healthy lifestyle.

"I'm excited for this next chapter in my life, I'm the happiest I've ever been, and for since I could remember I was sad," said Post Malone as he talked about his journey of losing 55 pounds. He went from 240 lbs to 185 lbs, he revealed at The Joe Rogan Experience Podcast. His inspiration? His daughter. He said that he is focused more on his health since becoming a father.
"It is definitely made me take better care of myself. I want to be around to see her go and do kick-*ss stuff. And before, you know, I was really drinking a lot and smoking a lot and stuff. I kind of took everything and toned it down a little bit and, you know, doing my best and really got my weight going," he said.
His weight loss journey started after he welcomed his daughter in May 2022, and on April 20233, he shared on his Instagram that post becoming a father he is now prioritizing his health.
He said it is simple, he decided to "kick soda and start eating better". He also is trying to cut down his smokes and brews or give up completely, which is taking time.
On his Instagram post, he wrote: "I've had a lot of people ask me about my weight loss and I'd suppose, performance on stage. I'm having a lot of fun performing, and have never felt healthier. I guess dad life kicked in and I decided to kick soda and start eating better so I can be around for a long time for this little angel. Next up is smokes and brews, but I like to consider myself a patient man... lol!"
While his fans were initially concerned about his weight loss, he reassured them that his "brain is in a super dope place" and he was "the happiest" he has ever been in a long time.
When he made his appearance in June 2024, on The Joe Rogan Experience Podcast, he said that his fans in fact, thought, that he started using drugs, due to his drastic weight loss. This is why he posted on Instagram to deny those allegations. “I remember, whenever I started losing my weight, everybody was like, ‘Hey, this is what meth looks like,’ and I started dancing on stage and having fun and having more energy and just enjoying life again, you know what I mean,” he told host Joe Rogan. “Like I mentioned, I was s***** for a long time, but I had my baby and I’m in a great f****** spot and then the first thing that happens is like, ‘Oh he’s on f****** drugs.’"
However, Malone has confirmed that he is not "any hard drugs".
In an appearance on The Howard Stern Show in October 2023, Malone said that he has not been on weight loss medication, rather he is now making better food choices.
Earlier, whenever he was on tour, he would go for junk, but now, he has made a deliberate choice to eat "grilled chicken" "carrots" with a "little bit of white rice with hot sauce". He said he was blown away to find out that hot sauce has no calories.
He also shared that he has cut out fried food and pizza. He shared that he would previously eat a lot of junk while on tour, especially because those places were open at 2 am after a show. However, when he made those small dietary changes, he lost 20 pounds, which made him think "let's keep building".
He also shared that he started cutting down on his soda intake. However, he would occasionally reward himself with one after a show.
He also showed off his weight loss in an August 2023 Instagram post on a mirror selfie and wrote: "Introducing Viceroy Chungus VonBattlepass, i love you," in caption.

For years, the idea of walking 10,000 steps a day has been treated like universal fitness wisdom, however, a recent study reveals that even a short stroll too could help you stay healthy.
From fitness trackers to morning-walk groups, the number has been repeated so often that many people believe it is a scientifically proven rule. The truth is far simpler and far more encouraging. New research shows that you do not need anywhere near 10,000 steps to improve your health. In fact, even a small amount of regular movement can dramatically lower your risk of heart disease and early death.
A new study published in the British Journal of Sports Medicine examined how step counts influence longevity and heart health, particularly in older adults. The findings were surprisingly optimistic. Scientists discovered that walking as few as 4,000 steps in a day, even if you manage this number only one or two days a week, can reduce the risk of death by 26 percent. It can also lower the risk of heart disease by 27 percent when compared to those who barely moved.
The benefits became even more striking when participants achieved the 4,000 step target on more than three days per week. In that group, mortality dropped by more than 40 percent and the risk of heart issues fell by 27 percent. These numbers show that moderate, regular walking has powerful protective effects on long-term health.
The study also explored whether aiming for higher step counts brings additional benefits. Researchers found that walking around 7,000 steps a day provides a slight extra advantage when it comes to living longer. However, it does not significantly change cardiovascular outcomes. This means that hitting 4,000 steps is already enough for meaningful protection, especially for older adults or people who are unable to reach higher counts.
Interestingly, the study also revealed that the number of days you walk matters far less than the total steps collected throughout the day. When scientists adjusted for total daily steps, the link between how many days people walked and their health results disappeared. The real takeaway is this: what matters most is how much you move overall, not whether you meet a daily or weekly quota.
Walking is one of the simplest forms of movement, yet its benefits are remarkably wide-ranging. It is gentle, low impact and accessible to almost everyone. Regular brisk walking has been shown to improve heart health, support weight management, boost mental well-being and improve mobility. These improvements occur because consistency helps the body adapt, even when the total effort seems small.
For older adults, or for anyone returning to activity after a long pause, this consistency is especially important. Small, steady efforts accumulate and gradually build up stamina. Over time, this reduces the risk of chronic disease and enhances overall fitness without stressing the joints.
If you want to enjoy the health benefits of walking, the key is to stay consistent rather than chase big numbers. A few practical tips can help you build a routine that feels realistic and enjoyable.
If you have been inactive for a while, begin with five to ten minutes of walking at a comfortable pace. Gradually increase your duration and distance over several weeks. This prevents strain and reduces the risk of giving up too soon.
Aim for manageable targets such as walking 20 to 40 minutes three days a week. Once this feels comfortable, you can add more time or increase your frequency if you wish.
If you are traveling or have long work hours, try breaking your walks into shorter chunks. A few five to ten minute walks throughout the day can help you stay on track.
When outdoor conditions are not ideal, choose indoor spaces such as malls, gyms, community centers or even long corridors at home or work.
Different routes help fight monotony and make walking more enjoyable. Rotate between parks, neighborhoods or indoor spaces to keep things fresh.

For many people, completing a daily step goal feels like a sign of an active lifestyle. Fitness trackers, wellness challenges and social media trends have popularized the belief that 10,000 steps can undo the negative effects of long hours spent at a desk. However, vascular experts warn that this assumption is misleading. Prolonged sitting continues to damage the veins and circulation even if one walks later in the day.
Vascular Surgeon and Varicose Vein Specialist Dr Sumit Kapadia recently posted a video on his Instagram channel explaining why step counts alone cannot protect vascular health. He said this is something he tells his patients almost every day. Even if someone completes their step goal in the evening, the body has already endured hours of immobility that strain the veins.
According to Dr Kapadia, circulation does not depend on how much a person walks in total. Instead, it depends on how frequently they move. Long stretches of sitting from nine in the morning to seven in the evening cause blood to stagnate in the legs. This stagnation triggers a progressive cycle: vein valve weakness, swelling, varicose veins and, over time, an increased risk of developing blood clots.
When a person sits for too long, blood flow in the legs slows down. Veins must work harder to pump blood upward toward the heart, especially against gravity. The longer blood pools in the lower legs, the more pressure builds inside the veins. Over time, this weakens the valves that keep blood moving in the right direction.
Dr Kapadia explained that even a healthy step count cannot reverse ten hours of immobility. The veins experience stress and pressure throughout the day, and walking later does not undo the hours of stagnation already endured.
People with sedentary jobs, long commutes or limited movement throughout the day are especially at risk. Additional factors like being overweight, having a family history of venous disease, or standing for long hours without moving can worsen the impact.
According to Dr Kapadia, vascular health depends more on how often you move than how much you walk. The solution is not long-distance jogging or intense workouts after work, but small, consistent breaks during the day.
He offered a simple rule for preventing vein damage:
Calf muscles play a major role in circulating blood back to the heart. When they contract, they push blood upward from the legs. But when they remain still for long periods, this pumping mechanism weakens. Small actions like ankle rotations, standing on tiptoes or short hallway walks can activate this pump and support vein health.
Dr Kapadia emphasized that the veins do not need marathons. They need movement. Tiny breaks spread across the day help prevent swelling, heaviness, varicose veins and long-term complications such as deep vein thrombosis.
In a world where work, travel and digital life keep people sitting for most of the day, this message is more relevant than ever. Steps matter, but frequency matters far more. The key to healthy veins is simple: move often.
