1. Hunger is not a ravenous appetite. A really hungry person should be cool and never in a great hurry to eat anything and everything.
2. Hunger is not a localised, uncomfortable sensation like cramps in the stomach
3. It is not lack of energy.

If it's not any of those things, then what do you think it is? Just curious. Because I think numbers one and two are prime examples of when you should eat.

Don't know whether I can agree with #1. I have not seen a "really hungry" person who would be cool and composed, without ravenous appetite.

I only eat when I'm hungry, and I usually wait about four or five hours before eating another meal. There are times when I want to eat before that, and I may have a snack.

Lol Some may look cool from the outside but in the inside they are craving for more food if they're really hungry.

I have always got a ravenous appetite, but I think it is more about self control and the types of foods that you eat.

I don't think you should immediately eat every time you feel a pang of hunger, but you shouldn't wait until the hunger is unbearable, either. When you're so hungry that you can't stand it, you're more likely to overeat.
