The use of rigid abdominal boards and compression garments to sculpt abs or eliminate belly fat is ineffective and borders on a scam.

Tibo InShape is entirely correct to highlight the ineffectiveness of these accessories for defining abs or eliminating belly fat.

Tibo InShape is entirely correct to highlight the ineffectiveness of these accessories for defining abs or eliminating belly fat. According to analyses by Harvard Health Publishing (expert opinion from Michael Clem), external compression does not allow for targeted local fat loss, because the loss of adipose tissue occurs globally and not in a localized manner. Furthermore, publications from the American Board of Cosmetic Surgery (expert opinion) explain that the refined silhouette effect is purely temporary, resulting from a simple mechanical redistribution of tissues and water loss through perspiration. In the long term, physical therapy journals (expert opinion) warn that restricting the waist in this way can weaken the deep muscles of the abdominal wall, which atrophy from being constantly assisted. It must be qualified, however, that this rigid compression tool has a real and validated utility according to the consensus of surgeons (expert opinion), but only during the post-surgical recovery phase to guide healing and limit swelling.

What the graded evidence says

Evidence: A-

Effect: localized fat change in trained vs untrained/contralateral limb (spot reduction) — pooled Hedges' g = -0.03 (95% CI -0.10 to 0.05), 13 studies, n=1158: no spot reduction
Measured on: healthy adults, both sexes, ages 14-71

Targeted 'fat-burning' exercises for a specific area are a myth; the evidence consistently shows fat loss is systemic, not local.
