Your ignoring the elephant in the room, everything you stated is secondary, tertiary or quaternary about the French women.
The prime reason is that culturally the French males despise obesity in their women, hence why their women are among the most self conscious in Europe.
This is what primarly drives them to these healthy eating habits, it's culturally and socially ingrained in them.
Our Xaalimo's don't have this because our males by in large champion obesity as do their mothers, aunties and grand mothers, this is unprecedented in our times and no other group does this.
Human behaviour is largely driven by consequences (fear) and incentives (hope), our women are happy being fat/obese, no shame to even come on YouTube and expose to the rest of the world.
And how can you blame them when they get a flood of comments from our sick males complimenting them excessively on their obesity on those videos ?
In such a toxic sick race-to-the-bottom climate, how can we ever expect them to develop any kind of self-awareness or self consciousness that the French women have?
