Idiotic and ineffective.
If you want to fight obesity, you have to start before people are adults and focus on sustained learning rather than a single course. So that would involve implementing a program throughout high school and middle school, rather than forcing a useless course on college students.
That would also have the benefit of actually reaching the right group. Because, as well all know, the people with the highest chance of being obese (as well as smoking, for that matter) are those without higher education.
But aside from being ineffective and idiotic, this measure also suffers from another problem: it ignores the fact that these students are adults, and are thus supposed to exercise personal freedom and responsibility - especially when it comes to their own bodies.
