Being obese in France?

In my short stay in France, I've not experienced such discrimination or even heard of people talking about it. I've seen a number of people who look overweight but this will not be the most common sight. As a result, I believe it is more sublimal and limited to individuals rather than France in general. Especially in my city, Lyon, I rarely see any person discriminated because of their size. Most of the time, it will be your own self-projection or assumptions that will separate you from people. Very many people  exercise a LOT and the food is very healthy if you choose to not eat many processed or pre-prepared meals. Hence as a conclusion, I'd say, get to France. By the time you learn French and get to learn people and their culture, you'll be done with your studies and internship. There's a higher chance of not getting a job if you're 'black/african' than if you're overweight.....and very many blacks have very many jobs....so basically, forget that book and get yourself the opportunity you need. Don't overthink it, it won't happen. But get ready to move a little faster coz the French hate being blocked just like in any other country. That's all I'd say. On the other hand, you could trying asking that question in a group called americans in france on facebook-the group has opinions from other expatriates from US. It would be difficultto get French people in an english speaking group.  Don't quote me though, this is just my subjective opinion.

By the way, you will not be the only obese person in the class.... There exists many overweight people. it's the exception though, not the norm.
