There's a difference between hunger as in, you feel sluggish and you would devour some gross junk food including the wrapper if you had it in front of you, and hunger as in, your stomach telling you through a niggly feeling that you ought to find some food fairly soon.
It's important to heed the first feeling with some good real food, including plenty of fat to stave off hunger for longer. It's better not to have too much carbs at each meal because it will fuel your appetite to eat way more than you need.
It's important to learn to ignore the second feeling, the niggly feeling, as the reason why half the population of the developed world is overweight or obese, is partly because they heed this feeling at every available opportunity and end up overeating because food is easily available.
I'm obese and wanting to lose weight so it's intermittent fasting for me. I don't eat anything at all (just have coffee/herbal teas/water) until the afternoon. I used to be a grazer, snacking frequently and my energy levels were like a roller coaster. But now I find a bit of niggly hunger doesn't bother me, I enjoy my afternoon/evening feast of Primal foods, and my energy levels are stable throughout the day.
