A non-invasive abdominal stimulation technique used over three weeks did not cause people to lose weight, meaning any reduction in waist size or fat thickness was not caused by losing overall body weight.

The Effects of Functional Magnetic Stimulation on Rectus Abdominis Muscle Size and Abdominal Subcutaneous Adipose Tissue Thickness

Cross-Sectional Study

Human

2025 Nov

The study found that using a special magnetic device on the belly made waistlines smaller and fat thinner, but people didn’t lose weight overall — so the changes weren’t because they lost weight, just because their belly got firmer and leaner.

Similar Assertions

A treatment using magnetic pulses on the abdomen for three weeks did not cause weight loss in healthy adults, but it did reduce waist size and fat thickness in the area, suggesting the effect stayed local and did not affect overall body weight.
