According to research reviewed by Gram, combining a diet with nonimmersive virtual reality training may offer added benefits for overweight women. In a 2026 pilot trial of 30 women, the combined group had lower body weight and deep belly fat than the VR-only group and scored higher on leg strength and balance tests than the diet-only group.
According to research reviewed by Gram, combining a healthy eating plan with active virtual reality (VR) workouts may lead to greater improvements in body weight, deep belly fat, and balance than diet alone in overweight women. The study was a small pilot trial published in 2026 in Games for Health Journal. Thirty women aged 18 to 45 completed a four-week program split into three groups: diet only, VR exercise only, or both. Women who combined diet with VR training lost more weight and deep belly fat than those who only did VR, and they scored higher on leg strength and balance tests than those who only changed their diet. Because the groups were tiny and many people dropped out for reasons unrelated to the study, these results are early signals rather than proof. Larger, longer trials are needed to confirm whether the combination works.
Key Statistics
A 2026 pilot randomized controlled trial of 30 overweight women found that adding nonimmersive virtual reality training to a diet produced significantly lower body weight than virtual reality training alone (P = 0.030).
In the same 2026 trial, women who combined diet with virtual reality training had significantly less deep belly fat than those who only did virtual reality training (P = 0.034).
The 2026 study found that women who combined diet with virtual reality training scored significantly higher on the 30-second sit-to-stand test than women who only followed a diet (P = 0.020).
The Quick Take
- What they studied: Researchers wanted to know whether eating a healthier diet, doing virtual reality exercise, or doing both works better for weight, body fat, and physical fitness in overweight women.
- Who participated: Thirty women aged 18 to 45 with a body mass index (BMI) between 25 and 40, which is in the overweight to obese range. They were split into three small groups: 10 on diet only, 9 on virtual reality exercise only, and 11 on both. About 60 women signed up, but many left the study after an earthquake unrelated to the research.
- Key finding: Women who combined diet with virtual reality training had lower body weight and deep belly fat than women who only did the virtual reality training. They also scored higher on a balance test and a leg strength test than women who only changed their diet. These differences were statistically significant, meaning they were unlikely to be due to chance alone, but the groups were very small.
- What it means for you: Adding virtual reality exercise to a healthy eating plan may offer extra benefits for weight, belly fat, and balance. Because this was a small, short study, it should not be seen as proof. Talk with a doctor before starting any new diet or exercise program, especially if you have health conditions.
The Research Details
This was a randomized controlled trial, which means participants were placed into groups by chance. Chance placement helps make sure the groups are similar at the start, so any differences found later are more likely caused by the program itself. Researchers compared three groups: one followed a diet, one did nonimmersive virtual reality training, and one did both.
Nonimmersive virtual reality means the participants used a screen-based system with movement-tracking, not a full headset that blocks out the real world. Sessions were held three times a week for four weeks. The two groups that did virtual reality training followed the same schedule, while the diet group focused on changing what they ate.
Before and after the program, researchers measured body weight, body mass index (BMI), deep belly fat, balance, and leg strength. They then adjusted the results for each person’s starting numbers, so people who began with different levels were compared fairly.
A randomized design is one of the strongest ways to test whether a program actually causes a change, because it reduces the chance that other factors explain the results. Comparing diet alone, exercise alone, and the two together also shows whether the combination offers something extra, rather than just whether one approach works at all.
Measuring both body composition and physical function is useful as well. A lower weight does not always mean better health, so tracking deep belly fat and balance gives a fuller picture of how the program affects the body.
The study was a pilot, which means it was designed to test the process and get early clues rather than deliver definitive answers. The final sample was only 30 women, split into groups of 9 to 11, which is small enough that a few people can strongly change the results.
About half of the women who started the study did not finish it. The researchers attributed this to an earthquake unrelated to the study, but dropouts can still affect results because the remaining participants may differ from those who left. The program also lasted only four weeks, so it does not show whether the changes last.
The study was published in a peer-reviewed journal, which means outside experts reviewed it before publication. Even so, its size and short duration mean it should be treated as a starting point for larger research.
What the Results Show
After accounting for starting differences, the three groups showed significant overall differences in body weight, BMI, deep belly fat (visceral fat area), balance, and leg strength. Balance was measured with the Functional Reach Test, which checks how far a person can lean forward while standing without losing their footing. Leg strength and endurance were measured with the 30-second sit-to-stand test, which counts how many times a person can stand up from a chair and sit back down in 30 seconds.
The most specific comparisons showed that women in the combined diet and virtual reality group had lower body weight and less deep belly fat than women in the virtual reality group alone. This suggests that the diet added value to the exercise program for these outcomes. The difference in body weight and deep belly fat was statistically significant after adjusting for multiple comparisons, a step that reduces the chance of false positive findings.
Women in the combined group also performed better than the diet-only group on the balance test and the sit-to-stand test. This suggests that adding virtual reality training to a diet may help improve physical function, not just the numbers on a scale. Deep belly fat is linked to heart and metabolic health, so changes in this measure are often considered meaningful.
The study does not report how large each change was in everyday units, so it is hard to say how much weight or fat a person might expect to lose. The findings describe group comparisons, not guaranteed results for any one person.
Beyond the main comparisons, the groups started out similar in age, body weight, height, BMI, and physical activity level, which supports the idea that the differences later on came from the programs. This similarity is an important sign that the randomization worked as intended.
The fact that virtual reality training alone did not produce the same advantages in weight and belly fat as the combined approach suggests that exercise by itself may not be enough for some goals. For people trying to change body composition, diet appears to play a central role in the results.
The researchers described the findings as suggestive rather than conclusive. Their own cautious wording signals that more research is needed before the combined approach can be recommended with confidence.
Previous research has generally found that combining diet with physical activity tends to produce better weight and fitness results than either approach alone. This study adds to that picture by testing a newer, more engaging format: screen-based virtual reality exercise. Virtual reality may make exercise more fun, which could help people stick with it.
Some earlier studies of video game and virtual reality exercise have found benefits for activity levels and mood, but fewer have looked at body fat and balance in overweight adults. This trial is one of the early attempts to examine those specific outcomes together.
Because the study is small and short, it fits best as an early step. Larger trials with longer follow-up will be needed to see whether these results hold up in broader groups of people.
The biggest limitation is the small sample. With only 30 women analyzed, a handful of participants can shift the results. Results from groups of this size are less reliable and may not apply to people of other ages, sexes, or health conditions.
The dropout rate was high, with about 60 women starting and only 30 finishing. Even though the researchers said the earthquake was unrelated to the study, people who leave a program can differ from those who stay, which may affect the findings.
The study ran for only four weeks, so it cannot show whether the changes last or whether people keep the weight off. It also included only women, so the results may not apply to men. Finally, the study does not clearly report the size of changes in everyday units, and it did not include a long-term follow-up.
The Bottom Line
Early evidence suggests that combining a healthy diet with virtual reality exercise may offer extra benefits for weight, deep belly fat, and balance compared with either approach alone. Confidence in this recommendation is low to moderate, because the evidence comes from one small pilot trial. Diet plus regular physical activity is already a well-supported approach, so the virtual reality element is best viewed as a possible way to make that routine more engaging.
If you want to try this approach, focus on the basics first: a sustainable eating plan and consistent movement. Virtual reality exercise can be one option among many, such as walking, cycling, or strength training.
This research is most relevant to adult women who are overweight and interested in combining diet changes with active exercise. It may also interest health coaches, fitness professionals, and researchers exploring digital tools for weight management.
People with heart disease, joint problems, balance disorders, or other medical conditions should check with a doctor before starting any new exercise program. Men, adolescents, and older adults were not part of this study, so the results may not directly apply to them. People who are not overweight may not see the same effects.
Participants in this study followed the program for four weeks, so that is the only timeline the research can speak to. Changes in body weight and body measures may appear within weeks, but the size and speed of change vary widely between people. Changes in balance and leg strength often show up sooner with regular practice.
The study did not test whether results last beyond four weeks. Sustainable change usually takes months of consistent habits, so a realistic expectation is a gradual process measured over several months rather than a quick result.
Frequently Asked Questions
Can virtual reality workouts help overweight women lose weight?
A 2026 pilot trial of 30 women found that adding nonimmersive virtual reality training to a diet produced greater reductions in body weight and deep belly fat than virtual reality training alone. Researchers stress that the study was small and short, so larger trials are needed before firm conclusions.
Does combining diet and virtual reality exercise improve balance?
In the same trial, women who combined a diet with virtual reality training scored significantly higher on the Functional Reach Test than women who only changed their diet (P = 0.033). This test measures how far a person can lean forward while standing, a common balance indicator.
How long did the virtual reality exercise program last in this study?
The program lasted four weeks, with virtual reality sessions held three times per week for the two groups that used it. Participants were women aged 18 to 45 with a BMI between 25 and 40, and the findings should be treated as early signals rather than proof.
Want to Apply This Research?
- Track your weight once a week at the same time of day, such as on Monday morning before eating. Also log how many times you complete your virtual reality or movement sessions each week, aiming for three, to match the study’s schedule. Record a 30-second sit-to-stand count every two weeks to track leg strength over time.
- Schedule three short movement sessions per week and pair each one with a daily food-logging habit. Use the app to set a reminder before each session and to log at least one balanced meal per day. Celebrate consistent weeks rather than focusing only on the scale.
- Review your weekly weight, session count, and sit-to-stand results in a monthly summary within the app. Look for trends over at least eight to twelve weeks rather than day-to-day changes. Share the summary with a healthcare provider at regular check-ins so they can help adjust your plan safely.
