Your criticisms are valid, however given the audience I doubt most Americans would actually 'fast,' and instead would simply skip dinner, wake up actually-hungry instead of just salty-fat-hungry, and perhaps lose a few pounds. Plus, light fasting (aka, skipping a couple of meals) actually feels really good!
