And, of course, I will give you a very filling recipe too!
Your "physical" hunger is regulated by the body through your hunger hormones. And of course, it should be. You don't want to be completely drained of fuel and nutrients for a long time. So, you're programmed to seek food when your body physically needs it. Some of those physical needs are that your stomach is empty or your blood sugar has dropped.
3 - Have a big glass of water. Now observe your hunger feeling for at least a minute. Really dig into the source of the feeling. It can be easy to jump to a conclusion, but that may or may not be the right one. So listen to your body and mind very deeply.
