Lower-calorie Mediterranean diet and exercise limit bone loss, even during weight loss, study finds
Older women who stayed on a reduced-calorie Mediterranean diet, walked and did resistance training for three years improved their bone density, especially in their lower backs, a new study found.
“A reduced-energy Mediterranean diet involves participants consuming a modified version of the traditional Mediterranean diet with approximately 30% fewer calories than their usual intake,” said coauthor Jesús Francisco García-Gavilán, a senior biostatistician at the University Rovira i Virgili in Tarragona, Spain.
Women in the study, who ranged in age from 55 to 75, were also able to prevent bone deterioration that typically occurs during weight loss, according to the research published Tuesday in the journal JAMA Network Open.
“Previous research has indicated that losing weight, particularly through diet alone, can lead to a reduction in bone density, which poses risks for older adults. Additionally, exercising alone does not always prevent this issue,” García-Gavilán said in an email.
“What is new in this study is the finding that combining a well-balanced, reduced-calorie Mediterranean diet with physical activity can prevent bone loss in older women, even while they are losing weight,” he said. “This emphasizes that the type of diet is important during weight loss, not just the calorie intake.”
The results of the study are not that surprising, said Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver.
“When you practice the lifestyle that human beings were always meant to live, which is moving a lot and eating predominantly simple, plant-based foods, all sorts of systems get better, including bone density,” said Freeman, who was not involved in the new research.

Why the Mediterranean diet?
The new study is part of the PREDIMED-Plus trial, a randomized clinical trial on lifestyle interventions conducted in 23 medical centers and hospitals in Spain. The trial included 924 older adults with metabolic syndrome who were overweight or had obesity. Half were randomized to eating a Mediterranean diet with no restrictions on calories and no requirement to exercise.
The other half were encouraged to walk for a minimum of 45 minutes per day six days per week and to do strength, flexibility and balance exercises three days per week. Their diet was cut to about 30% fewer calories than they typically consumed and only from a Mediterranean-style eating plan. Women in this group saw significantly stronger bones at one year and at three years into the study.
“While previous results from the PREDIMED-Plus trial highlighted benefits for maintaining lean mass and losing weight, this is the first publication to demonstrate that these lifestyle changes can also help preserve bone density, especially in older women,” García-Gavilán said.
The award-winning Mediterranean diet features simple, plant-based cooking, with much of each meal focused on fruits and vegetables, whole grains, beans and seeds, with a few nuts and a heavy emphasis on extra-virgin olive oil. Fats other than olive oil, such as butter, are consumed rarely, if at all, and sugar and refined foods are avoided.
Red meat is used sparingly, often only to flavor a dish. Eating healthy, oily fish, which are packed with omega-3 fatty acids, is encouraged, while eggs, dairy and poultry are eaten in much smaller portions than in the traditional Western diet.
Eating the Mediterranean way has been linked to reductions in the risk for breast cancer, dementia, depression, diabetes, high cholesterol and memory loss. Adherence to the diet can also lead to a healthier heart, weight loss and longer life.
But exactly why would the meal plan help preserve bone?
“The Mediterranean diet is rich in nutrients that promote bone health,” García-Gavilán said. “Nuts and dairy products provide essential calcium, magnesium, and vitamin D. Healthy fats, such as those found in olive oil, have been shown to reduce inflammation.”
Antioxidants such as vitamin C from fruits and vegetables may help protect and support bone cells, García-Gavilán added, while other important vitamins, like vitamin K found in vegetables such as spinach, play a role in bone formation.
“Together, these nutrients can lower the risk of bone loss and support bone maintenance, especially as we age,” García-Gavilán said. “Understanding this nutritional context is crucial for maintaining our long-term quality of life.”

Lisa Hogan, 54, stays in peak fitness with this ‘accidental’ workout: ‘I’ve given up the gym’
Clarkson’s Farm star Lisa Hogan is in peak physical shape, but you won’t find her spending hours in the gym. Instead, she credits her fitness to the completely accidental physical labour required to run Diddly Squat Farm.
In an official promotional interview for Amazon Prime series Clarkson’s Farm, she explained how harvesting goods for the farm shop she owns with husband Jeremy Clarkson has transformed her routine. ‘We spent a day picking elderflower from the hedgerows, we’re always foraging: I’ve given up the gym now, being on the farm keeps me fit,’ she said.
Besides foraging, her daily farm workout consists of various functional movements like lifting heavy crates, walking miles across uneven farmland terrain, and chasing livestock (an occurrence in pretty much every episode, if you haven’t seen it). In various other press interviews, she’s also mentioned using muscles she didn’t know she had, plus covering tens of thousands of steps across the farmland.
Her active lifestyle is built on the concept of NEAT (Non-Exercise Activity Thermogenesis). According to a study published in the American Journal of Physiology, NEAT represents the energy we burn doing everything that isn’t sleeping, eating, or intentional exercise (e.g. dedicated gym workouts).
The study goes on to specifically reference manual agricultural tasks, adding that a transition from a sedentary desk job to farm work like Lisa’s could naturally boost a person’s metabolic output by up to 1,200 calories per day, heavily contributing to long-term cardiovascular health, weight management and muscular endurance. This continuous, low-impact movement prevents the metabolic slowdown associated with prolonged sitting, effectively keeping Lisa fit without her even meaning to.
Of course, not everyone has access to a farm, and there are plenty of other forms of NEAT that could help increase your energy output and improve several health markers – even alongside a desk job. Some examples include:
- Washing the car
- Fidgeting
- Walking upstairs
- Walking the dog
- Carry grocery shopping
- Gardening
- Playing with children or pets
- Using a standing desk
- Walking to the gym, shops, office instead of taking public or private transport
The biggest takeaway from Lisa’s routine? That fitness might not be found in a gym, but right outside your back door.

Fitness: Does high blood pressure limit your exercise options?
Exercise has long been associated with heart health. Walk, run, swim, bike or lift on a regular basis and your risk of heart disease and stroke decreases dramatically. The rewards are almost instantaneous with a drop in blood pressure notable when you swap out time on the couch for time in the gym. That’s good news for anyone with high blood pressure, which increases the chances of adverse cardiac events.
The Heart and Stroke Foundation of Canada says about one in four Canadians have been diagnosed with hypertension. That number increases in an older demographic to 51 per cent in Canadians 60-79 years of age.
In most cases, exercise is considered safe for anyone who is effectively managing their blood pressure through medication or changes to their lifestyle. But it’s common for health-care professionals, including many organizations like the European Society of Hypertension, American College of Cardiology and the International Society of Hypertension, to advise keeping intensity in the moderate range to avoid the added cardiac stress associated with high intensity aerobic exercise. But the science related to the risk of hypertension and physical activity was largely informed by self-reported data that, when it comes to exercise, is unreliable. Not only do people routinely fudge how often they exercise, when it comes to intensity of effort there is little uniformity in determining whether a workout is light, moderate or vigorous.
With the growing number of studies using wearable devices to accurately track activity over the course of a full day, an increasing number of exercise recommendations are being scrutinized based on more reliable data. To find out more about the relationship between exercise intensity and hypertension, a team of Australian researchers analyzed a large cohort of adults with high blood pressure who wore an accelerometer to track their daily activity.
“Using wearables-based data, our study is among the first to investigate the potential role of cardiovascular stress-related physical activity properties (intensity and bout length) on major adverse cardiovascular events in adults with diagnosed hypertension,” the researchers said.
The researchers arranged 38,960 U.K. residents with hypertension into groups based on exercise intensity and duration. Short bouts of exercise were defined as up to three minutes at a moderate intensity and no longer than one minute at high intensity. Long bouts were any workout over five minutes of moderate intensity and over two minutes of high-intensity exercise. Hospitalization records of the cohort were then cross referenced over an eight-year period highlighting any documentation of a stroke, heart attack or heart failure.
The results offer new insight into how different types of exercise affect the heart health of people with high blood pressure.
The good news is short bouts (up to 60 seconds) of high-intensity exercise proved not only safe, but also offer a protective effect, with fewer cardiac events found in study participants who exercised using multiple short bouts of high-intensity exercise. But the same can’t be said for high-intensity exercise lasting more than 10 minutes.
“Such prolonged bouts could induce adverse vascular stress and adrenal gland dysfunction, which subsequently contribute to dysregulated cardiovascular function and induce increased arterial pressure,” the researchers said. “This can damage arterial walls, leading to increased stroke incidence.”
That doesn’t mean everyone with hypertension needs to avoid longer workouts done at a higher intensity. But if it’s a struggle keeping your blood pressure in a safe range and you want to start training for a speedy 5K, you may want to consult with your physician and/or cardiologist.
“The cardioprotective effects of physical activity in hypertension depend not only intensity, but also on the duration of the physical activity bouts,” the researchers said.
On the flip side, if you love doing multiple short bouts of high-intensity intervals in the pool, gym or on your bike, your heart is not only likely up to the challenge, but will also benefit from being put through its paces.
How do you know whether your workout is high or moderate intensity? Take the cue from the research team and start relying on wearables to track your exercise stats. Exercise intensity is based on heart rate response during exercise while factoring in your maximum heart rate, which is based on age, both of which can be tracked on most smart watches.
And since smart watches keep all the historical data from your workouts you can share your heart rate’s response to exercise with your medical team and discuss the most prudent form of exercise. Cardiac events while exercising are rare, but the accumulation of stress on the heart can lead to complications down the road. The best option is to find an exercise format that improves heart health in the long and short term as well as meeting the rest of your health and fitness goals.
“Our findings, alongside recent device-based studies focused on short bouts of high intensity activities, provide valuable insights for potentially re-evaluating treatment options for patients with hypertension,” the researchers said.

‘I’m 57 but my metabolic age is 10 years younger thanks to these 4 fitness habits’
Business owner and women’s health, fitness and menopause educator Meera Bhogal says her ‘relationship with exercise today is almost unrecognisable’ compared with what it was like when she was younger. Clearly, something is working, as she’s reduced both her biological and metabolic ages by a full decade.
So, what’s changed?
‘Growing up, the focus was very much on being as thin as possible – exercise was used as a tool to burn calories and compensate for food,’ Meera tells WH. ‘I spent hours doing cardio, aerobics and spin classes because I believed that feeling exhausted and drenched in sweat was what made a workout successful.’
‘Now, my approach is completely different – exercise is no longer about chasing a particular body shape. It’s about maintaining my health, preserving muscle mass, supporting my mobility and staying physically capable for decades to come,’ she adds. ‘I want to be strong, independent and healthy well into my later years, and my training now supports my long-term quality of life rather than simply changing how I look.’
The 4 habits behind her results
1. She practises yoga regularly
Meera says regular yoga has been ‘transformational’ for her.
‘Yoga has taught me how to slow down, connect with my breath and view movement as a form of moving meditation,’ she explains. ‘I practise Ashtanga yoga [often early in the morning] between 3 and 4 times per week, with sessions ranging from 30 minutes to 2 hours depending on my schedule.’
2. Strength training is her priority
‘My understanding of strength training has evolved significantly, and building and maintaining muscle is now one of my biggest priorities,’ says Meera. ‘Muscle supports healthy ageing, reduces the risk of osteoporosis, improves metabolic health and helps me stay strong and independent.’
‘I strength train around 4 times per week on average – some weeks it might be 3 sessions and other weeks it may be 5, but 4 is usually my baseline,’ she adds. ‘I generally train in the afternoon when I’ve had enough food and energy to perform well.’
Meera splits her strength sessions into push, pull, upper- and lower-body days, and focuses primarily on compound movements – exercises that recruit multiple muscle groups, such as deadlifts and squats.
A study published earlier this week involving more than 140,000 participants found that those who consistently performed between 90 minutes and 2 hours of resistance training per week had a 13% lower risk of death from any cause.
3. She doesn’t overdo cardio
While Meera says she doesn’t ‘do excessive cardio’ because preserving muscle mass remains a priority, she still includes it 2 to 3 times per week.
That might mean walking, StairMaster sessions, interval training on a bike or SkiErg, or shorter bursts of higher-intensity work.
The same study found that the lowest risk of death from any cause was generally observed among participants who combined aerobic exercise with strength training.
4. She prioritises recovery
Alongside strength and cardio work, Meera says she prioritises ‘recovery through mobility work, stretching, foam rolling and good sleep habits’.
Proper fuelling is crucial too.
‘I eat far more than I used to and have a much better understanding of protein, carbohydrates and fats,’ she says. ‘Rather than restricting food, I now focus on nourishing my body properly so it can perform and recover.’
‘Finding the right balance between strength training, cardiovascular fitness, nutrition, mobility, mindfulness and recovery has been life-changing,’ she adds.
Her advice for women who don’t know where to start?
‘The biggest mistake I see is women trying to do everything themselves by piecing together information from social media and expecting rapid results. Strength training is a skill and there’s real value in learning it properly,’ she says.
‘My first recommendation would be to seek support from a qualified coach or personal trainer, even if only for a short period.
‘Secondly, be patient – your body needs time to adapt. The person you are in week 1 will be very different from the person you are in week 10 if you stay consistent.
‘Finally, just start – whether that’s bodyweight exercises at home, a pair of dumbbells, or simply standing up and sitting down repeatedly from a chair. 5 minutes a day is infinitely better than doing nothing.’
