Key Takeaway

Combined nutritional supplements and exercise may improve BMI and lipid profiles in patients with overweight or obesity.

This meta-analysis evaluated the impact of combined nutritional supplementation and exercise on individuals with overweight or obesity. The study analyzed 315 participants divided into intervention and control groups to assess changes in Body Mass Index (BMI) and key cardiovascular markers.

Results indicated a statistically significant reduction in BMI for those receiving the combined intervention compared to controls. Furthermore, significant improvements were observed in lipid profiles, including substantial decreases in total cholesterol, triglycerides, and low-density lipoprotein cholesterol.

In contrast to the reductions in other lipids, high-density lipoprotein cholesterol levels showed a notable increase. These findings suggest that integrated lifestyle interventions may offer multi-faceted benefits for metabolic health in this patient population.

However, significant heterogeneity was noted across several lipid outcomes due to variations in supplement types and exercise protocols. Clinical application should be approached with caution until more standardized, large-scale trials can confirm these specific effects.

How this fits prior evidence

This meta-analysis extends prior evidence on weight management interventions. Prior coverage showed that exercise improves adiposity in sarcopenic obesity and that oral white kidney bean extract reduces weight by 1.62 kg. The current finding of a BMI reduction of 1.72 units with supplementation plus exercise is consistent with these modest effects. It also addresses a gap by examining combined nutritional and exercise interventions, contrasting with pharmacologic approaches like semaglutide or surgery.

Managing weight and heart health is a common goal for many people living with obesity. New data suggests that combining nutritional supplements with an exercise routine may offer a dual benefit: helping to lower body mass index (BMI) while also improving cholesterol profiles.

Researchers looked at 315 participants who were overweight or obese. Those who combined supplements with exercise saw significant improvements in their BMI and several blood markers, including lower total cholesterol, lower triglycerides, and lower LDL (the "bad" cholesterol). They also saw an increase in HDL (the "good" cholesterol).

While these results are promising, the study had some limitations. The types of supplements, the specific exercise routines, and the length of time people participated varied across the data. Because of these differences, we should view these findings as a positive sign rather than a guaranteed rule. Talk to your doctor about how this combination might fit into your personal health plan.

What this means for you:

Combining nutritional supplements with exercise may help lower BMI and improve cholesterol levels in people with obesity.

Common questions

Can these supplements actually help with weight loss?

The study found that combining nutritional supplements with exercise led to a significant reduction in BMI for participants who were overweight or obese. However, because the types of supplements and exercise routines varied among participants, you should speak with your doctor to determine the best plan for your specific needs.

How does this approach affect cholesterol levels?

Participants who combined supplements with exercise showed significant improvements in their lipid profiles. This included a decrease in total cholesterol, triglycerides, and LDL (bad) cholesterol, while also showing an increase in HDL (good) cholesterol.

Is this a guaranteed way to improve heart health?

The study shows a positive association between the combination of supplements and exercise with better blood markers. Because the study had high variation in how long people participated and what specific supplements they took, these results should be viewed as an encouraging finding rather than a certainty.

This study systematically evaluated the effects of nutritional supplementation combined with exercise on BMI and lipid profiles in individuals with overweight or obesity. A systematic search was conducted in PubMed, Embase, Web of Science, and the Cochrane Library databases from their inception to January 10, 2026, to identify randomized controlled trials (RCTs) comparing “nutritional supplementation combined with exercise” with “placebo.” The primary outcome measure was BMI; secondary outcomes included total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C). Weight-adjusted mean differences (WMD) and 95% confidence intervals (CI) were calculated using a random-effects model. Data analysis was performed using Stata 15. Study reporting followed the PRISMA statement, and the risk of bias of included randomized controlled trials was assessed using the Cochrane RoB 2.0 tool. Twelve RCTs involving 315 participants (161 in the intervention group and 154 in the control group) were included. Compared with placebo/control conditions, combined exercise and supplement-based interventions significantly reduced BMI (WMD = −1.72, 95% CI: −2.61 to −0.83; I2 = 68.7%) and LDL-C (WMD = −15.20, 95% CI: −17.12 to −13.27; I2 = 0%), increased HDL-C (WMD = 5.74, 95% CI: 3.66–7.83; I2 = 84.7%), and reduced TG (WMD = −16.54, 95% CI: −25.11 to −7.97; I2 = 83.1%) and TC (WMD = −15.30, 95% CI: −25.72 to −4.88; I2 = 92.7%). Subgroup analyses suggested that interventions incorporating aerobic exercise and those lasting 8–12 weeks, particularly 12 weeks, were associated with more favorable outcomes. However, substantial heterogeneity was observed for several lipid outcomes. Nutritional supplementation combined with exercise may be associated with improvements in BMI and lipid profiles in individuals with overweight or obesity. However, because the included studies varied in supplement type, exercise protocol, intervention duration, and participant characteristics, the findings should be interpreted cautiously. Larger, well-designed randomized trials with standardized intervention protocols and longer follow-up are needed to confirm these effects.
