Obesity

True this. I think if we all had no taste we would simply go with whatever is the cheapest at the moment. The incentive to eat healthier would still be low, as many people would save money by eating whatever would be the cheapest to eat.

An interesting theory comes to mind though. Would McDonald's still keep their food prices low if no one had any sense of taste, or would they raise the prices, knowing that they are on the lower end of food expenses?

I'm not sure if people would just eat the cheapest food. Different foods make you feel differently after eating them, and provide different benefits. We'd probably choose to eat foods based on actual nutrition value instead of just "the cheapest" (if it was affordable for your budget).

As for McDonalds, they'd have to lower them because less people would eat there. They'd have to give some sort of actual incentive to eat there at all other than it just being convenient. More people would be packing turkey sandwiches for lunch.
