Researchers at the University of Missouri found that diet and exercise can significantly improve liver disease caused by too much fat buildup.

They had one group of patients with liver disease follow a strict diet and do intense exercise for 10 months.

Another group received the usual care for their liver disease.

The group who dieted and exercised improved their liver health much more than the other group.

They lost weight, gained muscle, and improved their heart health.

    Do you work at a desk? You may need to consider extra exercise

    Sitting for the majority of the day comes with added health risks

    For those of us who work behind a desk, we’re doing a lot of sitting

    All that sedentary time adds up, and according to a new study published in JAMA, there are health risks associated with sitting for too long. 

    The researchers found that in order to counteract the negative effects of excessive sitting, desk workers are encouraged to do some extra exercise each day. 

    “These findings suggest that reducing prolonged sitting in the workplace and/or increasing the volume or intensity of daily physical activity may be beneficial in mitigating the elevated risks of all-cause mortality and cardiovascular disease associated with prolonged occupational sitting,” the researchers wrote

    Too much sitting comes with risks

    For the study, the researchers analyzed data from nearly 500,000 participants who were enrolled in a health surveillance program in Taiwan from 1996 through 2017. Researchers collected information on the participants’ jobs, lifestyle, physical activity, and overall metabolic health, including blood pressure, cholesterol, blood sugar, and more. 

    Ultimately, the researchers learned that sitting down for large portions of the day wasn’t good for the participants’ longevity. The study showed that those who had jobs that required sitting for the majority of the day had a 34% higher risk of death from cardiovascular disease, and a 16% higher risk of death from any cause. 

    Exercise can help

    However, you can counteract these negative health risks with some added exercise. The researchers explained that by increasing exercise each day, mostly sitting workers can lower their mortality risk. 

    When sedentary workers upped their exercise by 15-30 minutes per day, their mortality risk lowered to match another group in the study – those who are more active at work but aren’t physically active. 

    Another option: take frequent breaks throughout the work day to break up long periods of sitting. The study found that individuals who alternated throughout the day between sitting and standing were also not at an increased mortality risk. 

    “As part of modern lifestyles, prolonged occupational sitting is considered normal and has not received due attention, even though its deleterious effects on health outcomes has been demonstrated,” the researchers wrote. “Emphasizing the associated harms and suggesting workplace system changes may help society to denormalize this common behavior, similar to the process of denormalizing smoking.”

    Exercising in the morning may help you lose more weight, study finds

    Experts say that age and general response to exercise may play a factor in the findings

    Are you someone who sets their alarm for 5 a.m. to ensure you make your 6 a.m. workout? Or are you someone who gets all their work and responsibilities done throughout the day, and plans their workout for early or late evening?

    Or are you someone embarking on a health journey and you’re unsure when to plan your exercise? Results from a recent study published in Obesity may be of help. 

    Compared to those who worked out later in the day, researchers found that working out between 7 a.m. and 9 a.m. was associated with better weight loss outcomes. 

    “This is exciting new research that is consistent with a common tip for meeting exercise goals – that is, schedule exercise in the morning before emails, phone calls, or meetings that might distract you,” said clinical psychologist and behavioral weight management expert Rebecca Krukowski, PhD. 

    Early workouts yield better outcomes

    To better understand what time of day exercising yields optimal weight loss outcomes, the researchers analyzed data from over 5,200 participants enrolled in the National Health and Nutrition Examination Survey between 2003 and 2006.

    Over the course of the study, the participants wore accelerometers to measure their activity levels for at least four consecutive days but up to seven days total. Then, based on when they worked out, they were put into one of three groups – morning, midday, or evening. 

    The two primary factors that the researchers measured were body mass index (BMI) and waist circumference. The study revealed that those who worked out in the morning had both lower BMIs and lower waist circumferences, on average. 

    More to consider

    It’s also important to note that other factors may have affected these results. For instance, participants who regularly worked out in the mornings were older – by at least a decade – than participants in the other two groups.

    They also had never used tobacco or alcohol, had the most female participants than any of the other two groups, and also had the most amount of sedentary time of the three groups. 

    While the findings from this study certainly provide insight into health, wellness, and weight loss, experts say that there is more to consider. 

    “It is not known whether people who exercise consistently in the morning may be systematically different from those who exercise at other times, in ways that were not measured in this study,” Dr. Krukowski said. “For example, people who exercise regularly in the morning could have more predictable schedules, such as being less likely to be shift workers or less likely to have caregiving responsibilities that impede morning exercise. 

    “Predictable schedules could have other advantageous effects on weight that were not measured in this study, such as sleep length/quality and stress levels. In addition, the ‘morning larks’ who consistently rise early enough for morning exercise may be biologically different from their ‘night owl’ counterparts.”

    Consistency may be more important for workouts than duration of exercise, study finds

    Experts say a regular routine of shorter workouts may be better than doing longer workouts less often

    A new study conducted by researchers from Edith Cowan University is shedding light on an important exercise topic. Their findings showed that consumers who consistently exercise for shorter periods of time may reap more health benefits than consumers who do longer workouts less frequently. 

    “If you’re just going to the gym once a week, it’s not as effective as doing a little bit of exercise every day at home,” said researcher Ken Nosaka. “This research, together with our previous study, suggests the importance of accumulating a small amount of exercise a week, then just spending hours exercising once a week. 

    Getting consistent with exercise

    The researchers had 36 young adults involved in the study. They were broken up into three groups to do different variations of bicep curls. One group did just six muscle contractions one day a week, a second group did six muscle contractions five times per week, and the third group did 30 muscle contractions one day per week. When they did the exercise, the participants were hooked up to a machine that measures muscle strength and thickness. 

    The participants who did six muscle contractions five days a week ultimately had the greatest health outcomes. The researchers found that these participants increased their muscle strength by 10% and their muscle thickness by about 6%. Participants who did all 30 muscle contractions in one day improved their muscle thickness by just under 6%, but their muscle strength stayed the same. The group who did six muscle contractions once a week showed no improvements in muscle strength or thickness. 

    “People think they have to do a lengthy session of resistance training in the gym, but that’s not the case,” Nosaka said. “Just lowering a heavy dumbbell slowly once or six times a day is enough. We only used the bicep curl exercise in this study, but we believe this would be the case for other muscles also, at least to some extent.” 

    Though these findings highlight the importance of consumers being consistent with their workouts, the researchers also explained that taking rest days can be just as important. 

    “Muscle adaptations occur when we are resting; if someone was able to somehow train 24 hours a day, there would actually be no improvement at all,” Nosaka said. “Muscles need to rest to improve their strength and their muscle mass, but muscles appear to be stimulated more frequently. 

    “If someone’s sick and can’t exercise for a week, that’s fine, but it is better to just return to regular exercise routine when you’re feeling better.” 

    A new study conducted by researchers from Edith Cowan University is shedding light on an important exercise topic. Their findings showed that consumers who...

    Exercising at least 2.5 hours per week lowers risk of death, study finds

    Being consistent with physical activity can greatly extend consumers' lives

    A new study conducted by researchers from the American Heart Association highlighted the benefits of exercising regularly. Their findings showed that consumers who exceeded national recommendations for weekly exercise goals had a lower risk of death

    “The potential impact of physical activity on health is great, yet it remains unclear whether engaging in high levels of prolonged, vigorous, or moderate intensity physical activity above the recommended levels provides any additional benefits or harmful effects on cardiovascular health,” said researcher Dong Hoon Lee.

    “Our study leveraged repeated measures of self-reported physical activity over decades to examine the association between long-term physical activity during middle- and late-adulthood and mortality.” 

    Lifelong benefits of exercise

    The researchers analyzed data from over 100,000 people enrolled in the Nurses’ Health Study and the Health Professionals Follow-up Study between 1988 and 2018. The participants answered surveys about their lifestyles every two years. The questions covered subjects like alcohol intake, medical history, general health information, and exercise habits. 

    Current guidelines from the U.S. Department of Health and Human Services recommend that adults engage in 2.5 to five hours per week of moderate activity or 75-100 minutes per week of vigorous physical activity. Those who met the recommendations for either vigorous or moderate activity had a 20% lower risk of death. 

    The study findings showed that surpassing weekly exercise recommendations was linked with living a longer life. Doing two to four times the amount of moderate exercise each week was linked with a nearly 40% lower risk of cardiovascular disease-related deaths and a 30% lower risk of death from all causes. Similarly, doubling or quadrupling the amount of vigorous exercise each week lowered the risk of cardiovascular disease-related deaths by nearly 35%, and all-cause deaths dropped by 23%. 

    “This finding may reduce the concerns around the potential harmful effect of engaging in high levels of physical activity observed in several previous studies,” said Lee. 

    The researchers hope these findings highlight the benefits of consistent exercise. When consumers make physical activity a habit and work to balance moderate and vigorous activity goals each week, they’re likely to achieve better health outcomes. 

    “Our study provides evidence to guide individuals to choose the right amount and intensity of physical activity over their lifetime to maintain their overall health,” Lee said. “Our findings support the current national physical activity guidelines and further suggest that the maximum benefits may be achieved by performing medium to high levels of either moderate or vigorous activity or a combination.”

    Fitness trackers may motivate consumers to get physically active, study finds

    The wearable devices were found to promote around 40 more minutes of activity each day

    Many consumers are interested in improving their physical fitness, and a new study conducted by researchers from the University of South Australia has made a case for the benefits of wearable fitness trackers. Their findings showed that the devices are effective at boosting consumers’ physical activity by increasing daily walking by as much as 40 minutes. 

    “The overall results from the studies we reviewed show that wearable activity trackers are effective across all age groups and for long periods of time,” said researcher Ty Ferguson. “They encourage people to exercise on a regular basis, to make it part of their routine and to set goals to lose weight.” 

    Improving physical fitness 

    The researchers analyzed data from nearly 400 studies that included information on 164,000 people. All of the studies included data on wearable activity trackers (WATs) and how they affected the study participants’ activity habits. 

    Ultimately, the researchers learned that the devices were effective at promoting more physical activity. When wearing a fitness tracker, participants were likely to walk around 40 more minutes per day. 

    The researchers found that this boost in physical activity was also linked with weight loss. In five months, the extra walking was linked with an average weight loss of 1 kg, or 0.5 lbs. Though this number may seem small, the team explained that it can actually be meaningful long-term. 

    “The average person gains about 0.5 kg a year in weight creep, so losing 1 kg over five months is significant,” Ferguson said. 

    The researchers explained that the benefits of WATs may also go beyond physical activity and weight loss. Their work showed that the devices can allow consumers to improve symptoms related to anxiety and depression, as well as lower their cholesterol and blood pressure.

    Following a healthy lifestyle lowers risk of gestational diabetes, study finds

    Experts say it's especially beneficial for those who have a higher risk of developing the condition

    A new study conducted by researchers from the University of Helsinki suggests that adopting certain healthy lifestyle habits can lower the risk of gestational diabetes. The findings showed that this was especially true for those who have the highest genetic risk for the condition. 

    For the study, the researchers analyzed data from over 500 women who were enrolled in the Finnish Gestational Diabetes Prevention Study (RADIEL). The participants received dietary and exercise counseling during pregnancy and in the first year after delivery. 

    Based on the genes that are known to increase the risk of gestational diabetes, the team gave each participant a polygenic risk score (PRS) to assess their risk of developing diabetes. Those who had high sugar levels during pregnancy and after delivery were considered to have high risk scores. 

    The researchers learned that adopting a healthy lifestyle -- including following a healthy diet and exercising -- during and after pregnancy was linked with a lower risk of gestational diabetes. For women with the highest risk scores for gestational diabetes, these lifestyle interventions were particularly beneficial. 

    Moving forward, the team hopes these findings can work to identify women who may have the highest risk of developing gestational diabetes. Knowing who is the most genetically predisposed to gestational diabetes can help target women who would benefit the most from changing their lifestyles during pregnancy and beyond. 

    “At the same time, it’s important to realize that, in the case of diabetes, our genetic background does not determine our future,” said researcher Emilia Huvinen, a specialist in obstetrics and gynecology. “With the help of a healthy lifestyle, you can reverse the effect of a high genetic diabetes risk.”

    Active video games can lead to health benefits, study finds

    Virtual reality and active games can be a fun alternative to traditional exercise

    While many consumers know that exercise is an important part of a long, healthy life, working out isn’t always fun. However, a new study conducted by researchers from the University of Georgia suggests that there are healthy alternatives that consumers can try out.

    The team looked at exergaming – or active video gaming – and found that it could promote long-term health benefits by helping participants feel more in control of their workouts. These types of games include virtual reality games and games that require physical movement to play.

    “When an individual feels autonomous, they’re more likely to exercise or exergame on their own,” said researcher Sami Yli-Piipari. “They feel ownership over what they are doing, and they’re doing it for themselves, so it’s more likely they will keep up the activity.” 

    Active video games can benefit health

    The researchers had 55 people who didn’t regularly exercise participate in the study. They were divided into two groups: one group participated in traditional aerobics classes three times a week while the other group played exergames three times a week for six weeks. The team tracked the participants’ satisfaction and motivation with their workouts, as well as physical activity and exertion during exercise. 

    Although the participants in the aerobics classes worked out harder overall, the study showed that the participants who played exergames had more fun while working out. The researchers say that's an important point because enjoying a workout is likely to encourage consumers to keep up with it in the future. 

    “I see exergaming and technology-enhanced exercise as a stepping stone,” Yli-Piipari said. “It’s the first step in the right direction, especially for people who are not involved in any kind of exercise.

    Helping introduce kids to exercise

    The researchers believe exergaming could be a good way for parents to get their kids up and moving while also playing video games. Rather than sitting down and gaming, getting games like Just Dance, EA Sports Active, or Zumba Fitness World Party can help consumers of all ages stay active and moving. 

    While following a traditional physical activity routine can be difficult, the team hopes these findings offer an alternative perspective that could keep consumers interested in working out. 

    “We forget sometimes that it’s really hard for inactive people to take that first step,” Yli-Piipari said. “These games may be able to address that problem.” 

    While many consumers know that exercise is an important part of a long, healthy life, working out isn’t always fun. However, a new study conducted by resea...

    Lifelong exercise may lower the risk of muscle mass loss in older age, study finds

    Experts say remaining physically active may help protect against nerve decay

    Several studies have highlighted the longevity benefits associated with regular exercise, and now a new study conducted by researchers from the Physiological Society explored other health benefits linked with long-term physical activity

    According to the findings, consumers who exercised for most of their lives experienced significant improvements to their muscle health. The team found that they were less likely to lose muscle mass and muscle function, and their bodies produced more muscle stem cells; all of these factors are beneficial to long-term muscle regeneration and preventing nerve decay. 

    “This is the first study in humans to find that lifelong exercise at a recreational level could delay some detrimental effects of aging,” said researcher Casper Soendenbroe. “Using muscle tissue biopsies, we’ve found positive effects of exercise on the general aging population.” 

    Slowing down the aging process

    To understand the effect of lifelong exercise, the researchers divided 46 male participants into three groups: elderly sedentary, young sedentary, and elderly lifelong exercise. The researchers analyzed muscle biopsies and blood samples from each of the participants and also had them complete a muscle function test. 

    The study showed that those who had exercised for their whole lives had greater muscle health than those who had sedentary lifestyles. Participants who engaged in consistent recreational exercise were less likely to lose muscle mass and muscle function, and they were less likely to experience muscle fatigue. 

    The researchers also learned that lifelong exercise helped produce more muscle stem cells, which are important to overall muscle health – especially as consumers age. With more stem cells, the muscles are able to continue growing in older age and are better able to fight off degeneration. Over time, this can also lower the risk of nerve decay. 

    It’s important to note that there was no specific kind of exercise that was most successful at boosting participants’ muscle health. Any kind of physical activity proved to be beneficial at slowing the muscular aging process. 

    The team hopes these findings encourage consumers to stick with an exercise plan, as there are important long-term benefits to staying active. 

    “The single most important message from this study is that even a little exercise seems to go a long way, when it comes to protecting against the age-related decline in muscle function,” Soendenbroe said. “This is an encouraging finding which can hopefully spur more people to engage in an activity that they enjoy. We still have much to learn about the mechanisms and interactions between nerves and muscles and how these change as we age. Our research takes us one step closer.” 

    Several studies have highlighted the longevity benefits associated with regular exercise, and now a new study conducted by researchers from the Physiologic...

    New study explains why exercise is more difficult after not doing it for a while

    Experts say restricted blood flow is an important factor in exercise ability

    Exercising regularly can help guarantee a longer life, but consumers can often fall off the wagon and go through stages of being more sedentary. When they try to get back into their exercise routines, it can sometimes be a lot harder to get back into shape. 

    A new study conducted by researchers from the University of Leeds explored why exercise feels harder after you haven't done it in a while. Their findings showed that a protein that's important to blood flow, Piezo1, is deactivated when we stop exercising regularly. The researchers say compromised blood flow can make trying to get back into exercise more strenuous.

    “Exercise protects against cardiovascular disease, diabetes, depression, and cancer,” said researcher Fiona Bartoli. “Unfortunately, many people fail to exercise enough, for reasons such as injury and computer usage. This puts people at more risk of disease. The less people exercise, the less fit they become, often leading to a downward spiral. 

    “Although many responses to exercise are known, how the benefits of exercise are initially triggered at a molecular level is mysterious. Our study highlights the crucial link between physical activity and physical performance made at this level by Piezo1. Keeping our Piezo1s active by exercising may be crucial in our physical performance and health.”  

    Consistency is key with physical activity

    The researchers conducted their study on mice to better understand how the body responds to lapses in physical activity. Over the course of 10 weeks, one group of mice was left to exercise as they normally would while another group had their Piezo1 levels disrupted. 

    The researchers explained that the Piezo1 protein acts as a sensor for blood flow and moves blood to the muscles. When the protein was deactivated in some of the mice, the researchers observed important differences in their physical activity and overall health outcomes. 

    The mice in the experimental group weren’t running as fast, and they weren’t able to make as many complete trips around an activity wheel. This group wasn’t less willing to exercise, but their bodies weren’t as capable of performing as well.

    These findings emphasize the importance of the Piezo1 protein in exercise and why consistency is so important. Less exercise weakens the production of the Piezo1 protein, which ultimately limits blood flow to the muscles. This makes the body feel weaker and makes exercise feel more difficult. 

    “Our work sheds light on how Piezo1’s role in blood vessels is connected to physical activity,” said researcher David Beech. “A lot was already known about its role in blood vessel development, but far less was known about its contribution to vessel maintenance in adults. 

    “Our discovery also provides an opportunity to think about how loss of muscle function could be treated in new ways: if we activate Piezo1, it might help to maintain exercise capability." 

    Exercising regularly can help guarantee a longer life, but consumers can often fall off the wagon and go through stages of being more sedentary. When they...

    Exercise may help relieve dry eye symptoms, study finds

    Regular exercise can be beneficial for consumers struggling with irritated, itchy eyes

    While recent studies have found that exercise may benefit everything from lifespan to brain function, a new study explored another benefit of regular physical activity. According to researchers from the University of Waterloo, exercise may also help consumers who struggle with dry, itchy eyes.   

    “With so much of our activity tied to screen usage, dry eye symptoms are becoming increasingly common,” said researcher Heinz Otchere. “Instead of having to use eye drops or other alternative treatments, our study aimed to determine if remaining physically active can be an effective preventative measure against dryness.” 

    Relieving dry, itchy issues

    For the study, the researchers divided 52 participants into athletes and nonathletes. Participants in the athlete group exercised five times per week; nonathletes were required to exercise just once per week. The participants underwent eye exams both before and after each exercise session. 

    The researchers explained that consumers are most likely to experience dry and itchy eyes when their tear film isn’t protecting the eye as it should. The tear film is a thin protective layer that’s made up of oil, water, and mucin, and it ensures that the eye remains healthy. However, if any component of the tear film is compromised, it can cause irritation, dryness, and itchiness. In this study, the team wanted to observe any changes to the tear film before or after exercise. 

    Their findings showed that physical activity improved the participants' tear film stability and overall tear quality. Because the participants in the athlete group were exercising more frequently, they experienced more consistent and significant eye health benefits. However, any level of physical activity proved to be beneficial in relieving dry eye discomfort. 

    “It can be challenging for people to regularly exercise when the demand is there to work increasingly longer hours in front of screens,” Otchere said. “However, our findings show physical activity can be really important for not just our overall well-being, but for ocular health too.” 

    While recent studies have found that exercise may benefit everything from lifespan to brain function, a new study explored another benefit of regular physi...

    Daily exercise boosts brain function in older and middle-aged consumers, study finds

    Physical activity may have a direct impact on cognitive function

    Exercise has been found to benefit consumers’ well-being as they age, and a new study conducted by researchers from the University of California at San Diego explored the brain benefits of regular exercise. According to their findings, exercising daily was associated with a boost in brain function for middle-aged and older consumers. 

    “It was a very linear relationship,” said researcher Raeanne Moore, Ph.D. “We hypothesized that we would find this, but we couldn’t be sure because we weren’t telling people to increase their physical activity. They just did what they do every day.” 

    Staying active has brain benefits

    The researchers had 90 middle-aged adults participate in the two-week study. The group wore accelerometers to track their physical activity over the course of the study, and they also completed ecological momentary cognitive tests (EMCTs) twice daily on a smartphone app to assess their brain function. 

    The researchers learned that there was a clear link between physical activity and improved brain function. The participants performed far better on the cognitive assessments on days that they exercised when compared to days when they didn't exercise. These results held up for the participants regardless of other health complications, age, or ethnicity.  

    Moving forward, the researchers plan to see how these findings hold up long-term.  

    “We don’t know yet if there’s a cumulative, long-term effect to these small daily fluctuations in cognition,” said researcher Zvinka Zlatar, Ph.D. “That’s something we plan to study next – to see if performing physical activity at different intensities over time, in unsupervised settings, can produce long-term improvements in brain health and sustained behavior change.” 

    Exercise has been found to benefit consumers’ well-being as they age, and a new study conducted by researchers from the University of California at San Die...
