Researchers looked at 30 studies involving over 3,300 adults to find the best non-drug ways to reduce belly fat. They compared different types of exercise, acupuncture treatments, and combinations of both. The clear winner was a special acupuncture technique called ‘acupoint catgut embedding’ combined with electrical acupuncture. This combo worked better than exercise alone, regular acupuncture, or other approaches for shrinking waist size and losing weight. High-intensity workouts also ranked high, but the acupuncture combinations consistently showed the biggest improvements across multiple measures of belly fat.

The Quick Take

  • What they studied: Which non-drug treatments work best for reducing belly fat in adults
  • Who participated: 3,334 adults with excess belly fat across 30 different studies
  • Key finding: Acupoint catgut embedding with electrical acupuncture reduced waist size more than any other treatment
  • What it means for you: If you’re struggling with belly fat, combining specific acupuncture techniques may be more effective than exercise or diet alone, though you should discuss this with a qualified practitioner

The Research Details

This was a network meta-analysis, which means researchers gathered data from 30 separate high-quality studies and compared all the different treatments at once. They looked at studies published up to February 2025 that tested various non-drug approaches to belly fat reduction. Each original study was a randomized controlled trial, meaning participants were randomly assigned to different treatments, which helps ensure fair comparisons.

By combining multiple studies, researchers could compare treatments that were never directly tested against each other in the same study. This gives us a much clearer picture of which approaches work best than looking at individual studies alone.

The researchers used strict quality standards and only included well-designed studies. They used advanced statistical methods to account for differences between studies and ranked treatments based on their effectiveness.

What the Results Show

Acupoint catgut embedding combined with electrical acupuncture emerged as the top treatment for reducing waist circumference. This technique involves placing special threads under the skin at acupuncture points, then adding electrical stimulation. The second-best option was acupoint catgut embedding combined with regular manual acupuncture. High-intensity interval training (short bursts of intense exercise) ranked fourth among all treatments. For waist-to-hip ratio improvements, low-intensity steady exercise performed surprisingly well, ranking first, while acupoint catgut embedding alone was most effective for waist-to-height ratio.

The acupuncture combinations didn’t just help with waist size - they also led to greater reductions in overall body weight and BMI compared to other treatments. Warming needle acupuncture (where needles are heated) also showed strong results across multiple measures. Exercise-only approaches varied in effectiveness, with high-intensity methods generally outperforming moderate-intensity workouts.

Previous research has shown both acupuncture and exercise can help with weight loss, but this is the first comprehensive comparison showing that combining specific acupuncture techniques may be more effective than either approach alone. The findings support growing evidence that acupoint catgut embedding is particularly effective for metabolic conditions.

Most studies were relatively small and short-term. The acupuncture studies were primarily conducted in Asian populations, so results may not apply equally to all ethnic groups. The quality of acupuncture treatment can vary significantly between practitioners, and the studies didn’t always clearly describe the exact techniques used.

The Bottom Line

If you’re dealing with stubborn belly fat, consider consulting a qualified acupuncturist who specializes in acupoint catgut embedding, especially if combined with electrical stimulation. High-intensity interval training remains an excellent evidence-based option that’s more widely available. Combining approaches may be most effective, but work with healthcare providers to ensure safety.

Adults with excess belly fat who haven’t had success with diet and moderate exercise alone, or those interested in complementary medicine approaches. People with needle phobias, bleeding disorders, or certain medical conditions should avoid acupuncture treatments.

The original studies typically lasted 8-12 weeks, with most participants seeing noticeable waist reduction within 4-6 weeks of starting treatment. Maintenance likely requires ongoing sessions or transitioning to sustainable exercise routines.

Want to Apply This Research?

  • Measure waist circumference weekly at the same time of day, along with weight and waist-to-hip ratio to monitor progress across multiple indicators
  • Log high-intensity interval training sessions 3-4 times per week, or track acupuncture appointments and any associated dietary changes
  • Set up monthly progress photos and measurements, comparing waist circumference, weight, and how clothes fit rather than focusing solely on scale weight
