A new TikTok trend called the “watermelon diet” involves eating only watermelon for up to seven days in an effort to lose weight, but it’s not a sustainable approach.

“You may initially feel better due to eliminating certain foods—such as processed and ultra-processed foods and drinks—that could lead to fluid retention, weight gain, inflammation, bloating, headaches, gas, indigestion, fatigue, or other symptoms," Julia Zumpano, RD , a dietitian specializing in preventive cardiology at the Cleveland Clinic, told Verywell.

Depending on how long you follow the restriction, you may see an initial weight loss, but this has not been researched or proven. You will likely regain any weight lost after you stop, Zumpano said.
