Divergence
The survey’s winner finishes last in the feed.
Keeping the weight off matters, but in the open market it is the minimum people expect.
Convergence
A program that is simple to follow wins both reads.
It is fourth when people rank the list and first in the feed, at 177. Build the positioning on simplicity.
Divergence
Science and ease do better in the feed than in the survey.
Two kinds of message drew response: those built on the latest science, and those that give yo-yo dieters a newer, better option than the last one that failed.
Recommendations
Lead acquisition with simplicity, and prove it with science.

The full ranking
Nobody can lead with twenty promises at once. The main finding is a reversal: the survey puts keeping the weight off first by a factor of three, and the feed puts the same need last and a simple program first.
A program that is simple to follow leads. The bottom three are clearly below the average.
Change the scale, or select a need to test every other need against it. Needs that differ turn orange.
