Social Media Trend Promotes Laxative-Like 'Diarrhea Diet' for Summer Weight Loss

A wave of social media posts under the #SkinnyTok banner has been promoting what users call a "diarrhea diet," encouraging followers to take laxatives or stool softeners in pursuit of rapid summer weight loss. The trend has drawn attention from health commentators who warn that the practice carries serious medical risks, particularly as a cyclospora outbreak is being tracked in parts of the United States.

What the trend involves

Videos circulating on TikTok instruct viewers to consume over-the-counter products such as magnesium citrate or stimulant laxatives to induce frequent bowel movements. Influencers frame the resulting water loss as a shortcut to looking slimmer for summer, with captions such as "I'm skinny for the summer." Some clips have accumulated millions of views, amplifying the message among younger audiences who may not be aware of the dangers.

Why doctors are concerned

Medical professionals caution that repeatedly triggering diarrhea can lead to electrolyte imbalances, dehydration, and long-term digestive damage. Laxative misuse is also associated with rebound constipation and, in severe cases, cardiac complications. The concern is amplified by the ongoing cyclospora outbreak, a foodborne illness that causes watery diarrhea, cramps, and fatigue. Health agencies have linked recent clusters of cyclosporiasis to contaminated produce, and doctors worry that individuals already weakened by laxative use could face a harder recovery if infected.

Regulatory and platform response

• Some creators have added disclaimers noting that the videos are "not medical advice," though the disclaimers appear alongside explicit dosage suggestions.
• TikTok has previously removed content promoting dangerous weight-loss methods, but enforcement of the latest wave of posts appears uneven.
• Public health officials are urging viewers to consult a clinician rather than social media before using laxatives for cosmetic reasons.
