Fact check: What is the name of the weight loss supplement endorsed by Oprah Winfrey?

1. Summary of the results

Based on the analyses provided, Oprah Winfrey does not endorse a specific named weight loss supplement. Instead, the evidence reveals several key facts:

• Oprah uses weight-loss medications as a "maintenance tool" and has publicly discussed drugs like Ozempic, Wegovy, Mounjaro, and Zepbound ^{[1] [2] [3] [4]}
• She has a partnership with WW International (formerly Weight Watchers), in which she has invested ^{[1] [4] [5] [6]}
• Oprah actively warns fans against falling victim to companies selling weight loss products using her name and image, specifically mentioning weight loss gummies ^[7]
• Weight Watchers is now integrating prescription weight loss drugs into their business model ^[8]

2. Missing context/alternative viewpoints

The original question assumes Oprah endorses a weight loss supplement, but this premise appears to be fundamentally incorrect. Several important contextual factors are missing:

• Fraudulent marketing schemes extensively use Oprah's name and image to sell weight loss products without her authorization ^[7]
• Oprah has moved away from traditional diet culture and now focuses on prescription medications rather than supplements ^{[3] [4] [5]}
• WW International benefits financially from Oprah's public discussions about weight loss, as she is an investor and the company is pivoting to incorporate prescription drugs ^{[8] [4]}
• Some sources suggest Oprah should promote plant-based diets instead of her current approach ^[6]

3. Potential misinformation/bias in the original statement

The original question contains a false premise that could perpetuate misinformation. The question assumes Oprah endorses a weight loss supplement when:

• No credible sources identify any specific supplement she endorses ^{[1] [7] [8] [2] [3] [4] [5] [6]}
• Oprah explicitly warns against companies using her name to sell weight loss products ^[7]
• Her current approach focuses on prescription medications, not supplements ^{[1] [2] [3]}

This type of question may inadvertently legitimize fraudulent marketing claims that falsely associate Oprah with weight loss supplements. The question itself could be based on or contribute to the very scams that Oprah actively opposes.
