Long-Term Exercise Enhances Fat Tissue Health in Individuals with Obesity

Long-Term Exercise Enhances Fat Tissue Health in Individuals with Obesity
Research finds that people with obesity who exercise regularly show improved fat tissue health, which may lead to reduced risk of metabolic issues

A recent study from the University of Michigan has found that individuals with obesity who engage in long-term exercise have healthier belly fat tissue, allowing for more effective fat storage compared to their non-exercising counterparts.

This finding supports the importance of regular physical activity for metabolic health and offers encouragement for clients who aren’t able to shed fat despite a regular exercise routine.

Study Highlights

The research team wanted to explore the impact of years of exercise on fat tissue. They compared two groups of adults with obesity: 16 participants who reported exercising at least four times a week for an average of 11 years, and 16 individuals who had never exercised regularly but were matched in terms of body fat mass, weight and sex.

Researchers took samples of subcutaneous adipose tissue—fat located just beneath the skin—from both groups. The results showed that the exercisers had distinct structural and biological differences in their fat tissue, including increased blood vessel density, more mitochondria and higher levels of beneficial proteins. They also had lower amounts of collagen that could interfere with metabolism and fewer inflammation-causing cells.

“Our findings indicate that regular exercise not only helps expend calories but also modifies fat tissue in ways that allow for healthier fat storage during weight gain, which many people experience as they age,” said Jeffrey Horowitz, a professor of movement science at the U-M School of Kinesiology.

The implications of these findings are important. Storing fat in subcutaneous adipose tissue, the type sampled in this study, is considered healthier than fat accumulation around vital organs, which can lead to serious health issues.

Horowitz noted, “Increasing the capacity to store fat here reduces the likelihood of storing fat in unhealthy areas, such as visceral fat around the organs or in the organs themselves.”

This research builds on earlier studies that observed changes in fat tissue after shorter exercise periods. Horowitz emphasized the need for further investigation into how long-term exercise influences fat tissue health and whether specific types or intensities of exercise yield better results.

This study provides insights for personal trainers, emphasizing the importance of long-term exercise for metabolic health and fat tissue management. Trainers can leverage these findings to educate clients about the broader health impacts of consistent physical activity beyond just weight loss.

Moreover, fitness professionals can design sustainable long-term exercise programs that promote adherence and highlight the health benefits of regular activity, as opposed to pure aesthetics. Understanding that exercise can lead to healthier fat storage may also help address common client concerns about weight gain as they age, fostering a more positive mindset towards fitness.

While the study findings are positive, there are several limitations. The study involved only 32 participants, which may restrict the generalizability of the results. Also, the reliance on self-reported exercise data could introduce bias and inaccuracies in actual activity levels. The research compared current fat tissue characteristics rather than tracking changes over time, limiting insights into how exercise impacts fat tissue development.

The participants were matched based on specific characteristics, which may overlook other influential factors such as genetics and lifestyle. Also of note: the focus on subcutaneous abdominal fat may not capture the full spectrum of fat distribution and health implications, and the controlled setting may not reflect real-world conditions affecting exercise adherence.

Fitness coach says ‘just cardio isn’t enough’; shares 1 exercise women over 35 must do to stay strong and healthy

Fitness coach says ‘just cardio isn’t enough’; shares 1 exercise women over 35 must do to stay strong and healthy

As we age, our bodies naturally start losing muscle mass and bone density, which can affect strength, metabolism, and overall health. Many women over 35 notice changes in energy levels, weight distribution, and endurance, making it essential to adopt exercises that not only tone but also strengthen the body.

Tara LaFerrara, fitness coach and personal trainer, shares in her September 22 Instagram post why women over 35 should start incorporating strength training into their routines and how it can transform both body and health.

Why does muscle loss matter after 35

If you are a woman over 35 and not doing any sort of strength training, Tara warns you’re in for a rude awakening. “I’m talking the moment that your body starts to slow down, get weaker, and feel like you hurt more,” she shares.

“It is not just ageing, it is muscle loss, and it starts way earlier than you think. After the age of 35, we start losing muscle every single year. And that muscle is so important because it is your metabolism, your bone density, your energy, and just the ability to bounce back when life throws things at you,” says Tara.

Can cardio and pilates alone keep you strong

She emphasises that cardio and Pilates alone aren’t enough. “You need to lift, squat, push, pull, and press. It’s not about getting bulky and muscular, it’s about getting strong enough to handle ageing on your own terms.”

Her advice is simple: “So if you’re tired of feeling like your body is working against you, start working with it. Pick up some weights. Your future self will thank you.”

Strength training after 35 isn’t just about aesthetics; it’s about maintaining health, mobility, and resilience. As Tara highlights, incorporating resistance exercises into your routine is one of the best ways to support your body through the natural changes that come with age.

New Year’s Fitness Resolutions Start with Healthy Sleep | Newswise

New Year’s Fitness Resolutions Start with Healthy Sleep | Newswise

Newswise — As the New Year approaches, many Americans are setting fresh intentions to eat better and move more — and new data show those habits may deliver an unexpected bonus: better sleep. According to a new survey from the American Academy of Sleep Medicine, 59% of adults say eating a well-balanced diet helps them sleep slightly or significantly better. Staying active throughout the day may also help improve sleep. According to the survey, adults say exercising in the morning (42%) or evening (46%) helps them sleep slightly or significantly better. 

“Sleep is one of three pillars of a healthy lifestyle, including eating a well-balanced diet and incorporating regular physical activity,” said AASM spokesperson Dr. Kin Yuen. “When people make New Year’s resolutions or select their ‘nudge word’ for the year, they often prioritize diet and exercise. These changes don’t just support physical health—they also improve sleep.”

The findings suggest that New Year’s resolutions don’t need to be isolated goals. Improving one aspect of health, whether diet, exercise, or sleep, can create positive ripple effects across all three areas of wellness. This is especially true for younger adults, with those 25-34 being the most likely age group to say a well-balanced diet (64%) or exercise in the evening (60%) helps them sleep better.

“Sufficient sleep significantly reduces the risk of chronic illnesses, such as obesity, heart disease, and even depression and anxiety,” said Yuen. “Whether you’re improving your diet, increasing your activity level, or managing stress, prioritizing sleep gives you the energy and mental clarity needed to start the year strong.”

Here are some tips from the AASM on how to develop healthy sleep habits and reap all the benefits of your New Year’s resolutions:

  • Create a consistent bedtime routine — Make sure you are giving yourself enough time to get the recommended seven or more hours of sleep per night.
  • Make time in your daily routine for physical activity — Pick physical activities that you enjoy and that match your abilities.
  • Eat a well-balanced diet — Try to meet the recommended daily servings of fruits and vegetables, grains, and protein.
  • Disconnect from devices at night — Turn off all electronics at least 30 minutes to an hour before your bedtime to help prepare for sleep.
