Should the government regulate what we eat? why or why not?

This is an open ended question, it's all opinion based.

Case one: If the government regulates what we eat, they'd be keeping us healthy. Due to fast food slowly taking over, over time the next generation will be twice as far as the current generations obesity size.

Case two: If the government regulates what we eat, freedom isn't even given towards something so small but valuable to some people. The government shouldn't really part take that much in everyone's life but in my opinion at least, the government should take steps towards someone who is obese and help him or her lose weight and live a good life.

The answer would be analytical reasoning.
