How this ranking is built

Each of the 6 assistants — ChatGPT, Claude, Gemini, Perplexity, DeepSeek and Grok — was asked “What are the best weight loss programs? Recommend the top brands or products that people actually use, as a ranked list from best to worst. For each, give just the name.” multiple times. Brands are scored by a position-weighted measure across every answer (being named first, often, and by more assistants all rank a brand higher), then refreshed monthly. This reflects what AI recommends — it is not an endorsement by CiteHawk.

Questions about weight loss programs & AI

Why does AI recommend these weight loss programs?

AI assistants surface brands they encounter most often as authoritative answers — through reviews, comparisons, directories and citations across the web. Brands with strong, consistent presence in those sources get recommended first.

How often is this updated?

The AI Index is refreshed monthly across all 6 assistants, so the ranking tracks how AI’s recommendations shift over time.
