As read on 13 November 2026, 210 different winning e-commerce ads about weight loss have France as their main country, from 19 shops: the biggest niche market Poseidon follows. The biggest single ad, a video from epycure.com, had reached 2,766,753 people in the EU in 249 days.
An ad counts here when its main promise names weight loss ("minceur", "perte de poids", "kilos"…), from shops checked by hand, and each creative counts once. A winner is still running after 21 days or more. France is its main country: the country holding the largest part of Meta's breakdown for it. The full list, updated daily: weight loss in France.
Video and image, level on reach
| Format (Meta's label) | Different winning ads | Share | Median days live | Median EU reach |
|---|---|---|---|---|
| Video | 99 | 47.1% | 52 | 65,808 |
| Single image | 85 | 40.5% | 100 | 65,530 |
The two formats had reached the same number of people at the median, but the winning videos had done it in about half the time (52 days against 100).

The brands' own tests
Every reach below is Meta's EU total, not one country.
- officineimmortelle.com launched 4 versions the same day: the best reached 197,884 people in the EU (Meta's total), the weakest 26,560 (7.5×). best · weakest
- kosbiotic.com, 3 versions: 1,480,470 against 335,859 (4.4×). best · weakest
What this can't tell you
- Sales. Reach is how many people saw an ad, not who bought.
- Why a version won. Meta decides delivery; the page shows the result.
- How long they will run. These ads are still running, so days live are a floor.
How this was measured
- Source: Poseidon's free niche page for weight loss in France, built on 13 November 2026 at 09:35 UTC from Meta's EU transparency data read that day.
- Which ads: winners from 19 e-commerce shops checked by hand, whose main promise names weight loss; each creative counted once. A market needs 30 different ads from 5 shops, with no shop above 40% and the three biggest at 90% at most.
- Quotes: one line each (emojis removed), with our translation; videos and images are linked on Meta, never copied.
