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.

Hormonal Responses to Exercise

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.

Why Some People Struggle to Lose Weight

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.

Challenges in Implementing Exercise for Appetite Control

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.

Tips to Naturally And Safely Suppressing Appetite

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.

For people spending too much time on social media, fitness often takes a back seat—and not for the best. If you are someone who is new to the gym, one of the most difficult parts of the regimen is performing and holding a plank for long enough. Planks are among the most effective workouts for a stronger core and for better management of belly fat. Yet, holding one for even a minute can become a herculean task, even for younger individuals. But for people in their 20s, what is the ideal duration for holding a plank? Let’s find out.

What are the benefits of planks?

Experts say planks are very effective for strengthening the core, as they engage multiple muscles at once, such as the following:

1. Obliques (sides)
2. Rectus abdominis (the front of your abdomen)
3. Transverse abdominis (the deep, stabilising muscles that wrap around your midsection)

Unlike ab exercises like crunches, planks target multiple muscle groups at once. This workout also helps stabilise the core while moving. It is effective for maintaining proper alignment during movement and for protecting the lower back. Experts say that, alternatively, lifting boxes at home is more or less the same as loading and unloading boxes from your car to your home. This emphasis on stability becomes more important with age.

In a 2012 study, older adults who successfully completed a nine-week core stability programme reported better spinal mobility, improved trunk strength, and enhanced dynamic balance. These factors collectively reduce the risk of falls. However, experts warrant caution, stating that focusing too much on plank duration could make the workout less effective. Instead, there is a good reason to strive for steady form and, over time, better endurance.

How long should you be able to hold a plank?

Timing a plank is not a one-size-fits-all approach. Several factors can influence how long one can hold a plank position, including overall fitness; body weight and proportions; as well as experience with planks and other breath control and muscular endurance exercises. Fitness experts say that age plays a significant role when it comes to plank duration. As one gets older, natural changes such as weaker joints and a decrease in muscle mass and strength can affect how long a plank can be maintained. Consistent training can help increase this duration.

While there is no specific number that everyone must aim for, people should try to improve their plank duration based on their age. Take a look at the ideal duration of holding a plank across age groups:

1. 18–39 years: 45–99+ seconds for the general population; 1–2 minutes for fitter individuals
2. 40–59 years: 30–75 seconds for the general population; 45–90 seconds for fit individuals
3. 60+ years: 20 seconds to one minute for the general population; 30–75 seconds for fitter individuals

High blood pressure (BP) has become a public health problem that is driving cardiovascular diseases like heart attacks and strokes globally. While medications are important to keep hypertension under control, lifestyle changes and healthy practices are also crucial.

Several global health guidelines recommend regular physical activity, but adhering to exercise programs daily becomes a challenge for many people. But in the overtly busy schedules, sparing 10 minutes for an exercise regimen can be easier than travelling to the gym.

A large randomized clinical trial, published in the Journal of the American College of Cardiology (JACC), has proved that a traditional Chinese mind-body practice — baduanjin — may help lower blood pressure, that too, without any equipment.

Baduanjin is a slow, structured movement, focused on deep breathing and meditation.

Importantly, the clinical trial proved that the ancient Chinese technique could lower BP as effectively as brisk walking.

In people practicing baduanjin, BP reductions were seen after three months and were sustained for one year.

"Given its simplicity, safety, and ease with which one can maintain long-term adherence, baduanjin can be implemented as an effective, accessible, and scalable lifestyle intervention for individuals trying to reduce their blood pressure," said Jing Li, Director, National Center for Cardiovascular Diseases in Beijing, China.

Baduanjin: The 10 Minute Routine

Baduanjin is a standardized eight-movement sequence that integrates aerobic, isometric, flexibility, and mind-body components.

It has been in practice for centuries and commonly performed in community settings across China. The routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction.

Because it is low- to moderate-intensity, it is considered safe and accessible for many adults.

The Clinical Trial

A team of Chinese researchers led the first large, multicenter randomized trial to look at the impact of baduanjin on blood pressure.

They followed 216 participants, aged 40 years or older, across seven communities to determine changes in 24-hour systolic BP from baseline to 12 and 52 weeks.

Compared to people indulging in self-directed exercise, practicing baduanjin five days a week reduced

• systolic blood pressure by approximately 3 mg Hg
• systolic blood pressure by 5 mg Hg.

Notably, the benefits were sustained even without ongoing monitoring, a key challenge for many lifestyle interventions that struggle to maintain long-term adherence outside structured programs.

"Baduanjin has been practiced in China for over 800 years, and this study demonstrates how ancient, accessible, low-cost

approaches can be validated through high-quality randomized research," said Harlan M. Krumholz, Editor-in-Chief of JACC and the Harold H. Hines, Jr Professor at the Yale School of Medicine.

"The blood pressure effect size is similar to that seen in landmark drug trials, but achieved without medication, cost, or side effects. This makes it highly scalable for community-based prevention, including in resource-limited settings," they added.

How To Practice Baduanjin

• Stand upright with your feet shoulder-width apart and keep your movements slow and controlled.
• Coordinate each motion with steady, deep breathing, inhaling and exhaling smoothly as you move.
• Move through the traditional eight postures in sequence, focusing on posture, balance, and relaxation rather than speed or force.
• Practice for about 10 to 15 minutes a day in a quiet space, maintaining calm attention throughout.

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.
