Major retailers like Amazon and eBay removed misleading weight-loss supplement ads with unproven claims, per a UK consumer watchdog report.

A consumer watchdog investigation found that major retailers including Amazon, eBay, and Temu are making misleading claims about weight-loss supplements, promoting unproven benefits like fat burning and targeted weight loss. The findings, reported by Which?, revealed over 50 listings were removed after highlighting unsupported assertions, such as ingredients boosting fat metabolism or reducing carbohydrate absorption, despite these claims being rejected by the UK’s health claims register. Some products falsely suggested effects comparable to prescription weight-loss treatments, violating advertising rules. Retailers confirmed removing the flagged items, while officials stressed that health claims must be evidence-based and approved, calling for stronger enforcement to protect consumers.
