If you are hungry eat, thirsty drink, listen to your body, if i eat a giant meal i feel sluggish and tired. Can you thrive on 1 meal a day, sure..Serge Nubret is a perfect example of that. You have to listen to your body and its signals.
Well stated and for the greater part of the population, true. That caveat is there simply because some people are just stupid and stuff their faces because they want to.
As with liberals, the reason many fat/out of shape people are blind is because they shut their eyes of their own free will. A calorie is just that - a calorie. It's what you do with it that determines it's value, if you will. A calorie. Energy either expended or stored. Not the nutritional value of an item, just how many calories it provides. There is a distinction.
You don't have to wear a lab coat to be able to know that if you take in more than you use, you're going to get fat..er. Hand me the phone.
