why can't all food be 0 calories?

that would be stupid, better to eat food with both the proper types of nutrients and calories for you body and metabolism

Because non food is already zero calories

But we need calories to function properly. Without proper caloric intake and nutrition we'd all die :D

cuz dead.

Eat some pizza.. A few fat and calories are good for you

Or eat salads and celery and such

If it could be done, it would be squelched by the diet and fitness industries plus opposed by all the pharmaceutical companies.

Except for those poor souls who have disorders that need more calories to survive.

if food dont some else will make a person gain weight

Keep the great ideas coming

You would die. No?

But you can eat nothing...

We need calories
