He is living in America now, not France or someplace in Africa, I don't want to sound racist but I have known many skinny Africans that came to the USA for jobs or university, some stay skinny, especially if they bring a woman with them that can cook, others though, they get a taste of all of our fast foods and their brains go haywire, they can't stop themselves, my Nigerian professor said he ate 2 whole buckets of pop-eyes chicken his first day off the plane (he went to Grad school at Tulane in NO), they balloon up in only 2 or 3 months and look like obese natives.
