Seeking fitspiration on social media?
Now that it’s 2024, perhaps you’ve thought about taking up a new exercise program, eating better, or some other ways to improve your health. That’s great! Or, as my grandfather would say, “there’s nothing wrong with that” — his highest possible praise.
In fact, few medical treatments rival the massive health benefits of regular exercise. But how do you decide which type of exercise is best for you? Well, you could get advice from your doctor or a personal trainer. You might read books on fitness or sample exercise classes. It turns out, though, that many people are simply scrolling through tons of engaging “fitspirational” posts on social media. If you do that regularly — more often, say, than taking a brisk walk — a new study suggests you should rethink that strategy.
What exactly is fitspiration?
Fitspiration describes social media posts intended to inspire physical fitness and promote health. You can find fitspirational posts on TikTok, Instagram, Facebook, and other popular social media sites. Typically, they feature glossy photos and videos packaged with exercise and diet recommendations, accompanied by encouraging messages and quotes.
On Instagram alone, a search for #fitspiration (or related hashtags such as #fitspo) currently lists nearly 100 million posts. Most of them display images of attractive, lean, and fit women as they exercise and talk about fitness and optimizing health.
What’s the problem with fitspiration?
The potential benefits of a pro-fitness message reaching millions of people are obvious. But the message has to be credible and valid. And, importantly, posts should not convey inaccurate, unhelpful, or even harmful information. That’s where the problems start.
Clearly, social media posts about fitness can have positive effects, according to some research, especially when focused on realistic exercise goals rather than appearance. However, fitspirational posts may have downsides for viewers, including
- increased body dissatisfaction
- negative mood
- decreased perception of attractiveness
- embracing thinness as the ideal
- a limited range of diverse body shapes and types, suggesting that beauty is defined by being ultra-fit and thin
- a focus on appearance rather than function and capability.
A study of #fitspiration: Do these social media posts actually inspire fitness?
A recent study assesses the quality of content with fitspiration hashtags posted by Instagram influencers. The results were disappointing, though not surprising.
The authors identified 100 Instagram accounts of the most popular fitspiration influencers. Each of these accounts’ last 15 posts was analyzed. Posts were not considered credible if they
- displayed nudity or revealing clothing, such as wearing a bikini at the gym
- sexualized the person exercising, such as focusing on a woman’s breasts
- included images of extreme body types, such as people who are severely underweight or extremely muscular
- conveyed messages encouraging thinness or other negative messages rather than emphasizing health
- contained fitness information in three or fewer posts out of 15.
Here’s what the researchers found:
- 26% portrayed sexualized images
- 22% posted nudity or images of people exercising in revealing clothing not appropriate for exercise
- 15% featured people with extreme body types
- 41% posted fitness-related content in three or fewer posts.
A quarter of these accounts failed the credibility test on more than one of these criteria. Even among the accounts considered credible, only half were posted by people with credentials related to fitness or health, such as certification as a physical therapist or personal trainer.
While this study did not examine whether the posts had an actual impact on fitness outcomes, the findings raise questions about the quality of fitspiration content.
What does this mean for you?
If you’re looking for fitness-related health content, seek out the best information you can. Be skeptical of any sources lacking credentials related to fitness. Be especially wary of posts selling a product or service.
The authors of this study established certain criteria for fitness-related content they reviewed. You could apply this to posts you see online.
The bottom line
It should be no surprise to find that when it comes to health information, social media may not always be the best place to start.
While taking steps to improve your health is commendable — truly, there’s nothing wrong with that! — getting motivated to be more physically active is just a start. Information you rely on to improve your physical fitness shouldn’t just look appealing. It should be well-vetted for safety and backed by solid evidence that it can actually improve your health.
Here’s to better fitness in the New Year!

How well do you score on brain health?
Need another jolt of motivation to shore up a resolution to shed weight, sleep more soundly, boost nutrition or exercise levels, or cut back on alcohol? Then you'll be pleased to learn that any (and all) of these efforts can also add up to better brain health.
An international study led by researchers at the McCance Center for Brain Health at Massachusetts General Hospital devised and validated a Brain Care Score (BCS) card that makes it easy to total up what you're doing well and where you might do better. The prize is a healthier brain — specifically a lower risk for dementia and strokes.
Designed to predict how current habits might impact future brain health, the user-friendly scorecard is apparently the first of its kind, says Dr. Andrew Budson, a lecturer in neurology at Harvard Medical School.
"It's a real service that the researchers have developed a scale like this and completed the first study to determine if scoring worse on this scale raises your risk for dementia and stroke," says Dr. Budson, who wasn't involved in the analysis. "On one hand, no one's done something quite like this before. On the other, however, it's really wrapping together health factors everyone has known for a number of years in new packaging."
What's included on the scorecard?
Called the McCance Brain Care Score, the card tallies points from 12 physical, lifestyle, and social-emotional domains.
Physical components relate to
- blood pressure
- blood sugar
- cholesterol
- body mass index (BMI).
Lifestyle components include
- nutrition
- alcohol intake
- smoking
- aerobic activities
- sleep.
Social-emotional factors inquire about
- stress management
- social relationships
- meaning in life.
Each response is given a score of 0, 1, or 2, with the highest possible score totaling 21. Higher scores suggest better brain care.
"All these physical and lifestyle factors can contribute to the risk of dementia to some extent through strokes," Dr. Budson says. "Those that aren't a risk through strokes are usually related to the fact that a healthy brain is a brain that's using all of its parts. Engaging in healthy relationships and meaningful activities helps us maintain good brain structure and function."
What did the analysis involve?
The study was published online in Frontiers of Neurology in December 2023. It involved nearly 399,000 adults ages 40 through 69 (average age 57; 54% women) who contributed personal health information to the UK Biobank.
During an average follow-up period of 12.5 years, participants recorded 5,354 new cases of dementia and 7,259 strokes. Researchers found that participants with higher Brain Care Scores at the study's start had lower risks of developing dementia or strokes over time.
These threats to health and independence take a stunning — and growing — toll on people in the US. Dementia affects one in seven Americans, a rate expected to triple by 2050. Meanwhile, more than 795,000 people in the United States suffer a stroke each year, according to the CDC.
What did the study find?
Each five-point step higher in the BCS rating assigned when the study began was linked to significantly lower risks of dementia and stroke, with those odds varying by age group:
- Participants younger than 50 at the study's start were 59% less likely to develop dementia and 48% less likely to have a stroke with each five-point higher score on BCS.
- Participants 50 through 59 at the study's start were 32% less likely to develop dementia and 52% less likely to have a stroke with each five-point higher score on BCS.
But those brain disease benefits appeared to diminish for those older than 59 at the study's start. This group experienced only 8% lower odds of dementia and a 33% lower risk of stroke with each five-point higher score on BCS. Study authors theorized that some of these participants may have already been experiencing early dementia, which is difficult to detect until it progresses.
"I feel very comfortable that the study's conclusions are entirely correct, because all the factors that go into its BCS are well-known things people can do to reduce their risk of stroke and dementia," Dr. Budson says.
What are the study's limitations?
However, Dr. Budson notes that the study did have a couple of limitations,. The UK Biobank fell just short of collecting all the components of the BCS in its dataset, lacking meaning-of-life questions. So its scores ranged from 0 to 19, not up to 21. "It's a practical limitation, but it should be acknowledged that so far, there have been no studies to validate the actual 21-point scale they're recommending we use," he says.
The analysis also evaluated participants' scores at just one point in time instead of several, Dr. Budson says. Future research should determine whether people can lower their stroke and dementia risk by improving their BCS over time with behavior and lifestyle changes.
How can you play this game at home?
While better brain health may be the clear prize of a higher score, it's far from the only benefit. That's because improving any health component of the BCS also benefits our overall well-being.
"By improving these factors, not only will people help their brain, but they'll also help their heart and reduce their risk of cancer," Dr. Budson adds. "These factors will absolutely also improve your psychological health, which is certainly an important part of brain health."
The scale's simple breakdown of health factors also makes it easy to focus on tweaking one or two without getting overwhelmed.
"Let's say someone's nutrition isn't perfect — and they know it — but they're not willing to change their diet. Fine. They can then decide to do more aerobic exercise, for example, or to stop drinking, or to get the sleep their body needs," he says.
What one change could put you on a path to better brain health?
If he had to choose just one factor to improve brain health, Dr. Budson would focus on meaning of life, "which means you generally feel your life has meaning or purpose," he says. To do that, he suggests giving deep, quiet thought to what you wish your life's purpose to be, whether you expect to live a long time or just a few years.
"Once you have a purpose, then you have a reason to follow through with assessing all the other items on the BCS scale and seeing what you can do so you'll be around longer, and be competent and capable longer, to help fulfill the meaning and purpose of your life," he says.
