This is one of the questions of our era.

When you're scrolling through social media, how can you tell what's real?

Misinformation can be dangerous, especially when it's related to your health.

Anything can be posted online without being fact-checked.

But if you heard about the secret to permanent weight loss, wouldn't you give it a follow?

Tanya Zuckerbrot, founder of the trendy high-fiber F-factor diet, has celebrity followers

including Megan Kelly and Supermodel Olivia Culpo.

Tanya has a nice house, nice husband and nice vacations, a very aspirational lifestyle.

But allegations of troubling side effects with the diet began to surface, and people started

to question, is she selling powder or power?

Emily Gellis, a popular fashion influencer, saw these allegations and criticized the

diet to her own large social media following.

In fact, that's an understatement.

She launched a crusade to expose Tanya and the F-factor diet.

Emily thought bringing awareness to the claims would be enough, but that was just the beginning.

What started as an online feud escalated into real-world threats, lawsuits, and a mess

of drama.
