Fact check: Has Oprah ever been involved in a lawsuit related to weight loss products?

1. Summary of the results

Yes, Oprah Winfrey has been involved in multiple lawsuits related to weight loss products, but as the plaintiff seeking to protect her name and trademark, not as a defendant. The evidence shows several distinct legal actions:

• Oprah filed lawsuits against companies using her name to sell keto gummies and CBD gummies without permission ^{[1] [2]}
• She and Dr. Mehmet Oz sued companies that used their names to sell dietary supplements containing acai berries without authorization ^[3]
• The Federal Trade Commission obtained court orders to halt operations that used fake celebrity endorsements, including Oprah's name, to market unproven diet pills ^{[4] [5]}

These cases demonstrate a pattern of unauthorized commercial exploitation of Oprah's celebrity status to promote weight loss products she never endorsed.

2. Missing context/alternative viewpoints

The original question lacks important context about Oprah's complex relationship with weight loss and diet culture:

• Oprah has publicly apologized for being a "major contributor" to diet culture throughout her career ^[6]
• She currently uses weight-loss medication as a "maintenance tool" and has spoken out against shaming around weight management ^[7]
• She has faced recent backlash for making controversial comments about "thin people" after taking weight-loss drugs ^[8]

This broader context reveals that while Oprah fights against unauthorized use of her name for weight loss products, she has simultaneously been a significant figure in promoting diet culture and has her own ongoing relationship with weight management tools and medications.

3. Potential misinformation/bias in the original statement

The original question is factually neutral but could be misleading by omission. Someone might interpret "involved in a lawsuit related to weight loss products" to suggest Oprah was sued for promoting harmful products or making false claims. However, the evidence shows she was consistently the victim of trademark infringement and unauthorized endorsements ^{[1] [3] [2]}.

The question also fails to acknowledge that companies systematically exploit Oprah's trusted reputation to sell unproven weight loss products, benefiting financially from her credibility while potentially harming consumers who believe she endorsed these products ^{[4] [5]}.
