Have you tried drinking more.  I know it sounds bizarre but sometimes the body confuses hunger with thirst.  Next time you feel hungry try drinking some water first maybe it will do the trick.

I get this from time to time. Usually when I'm really run-down. Perhaps you need to take more iron with your diet, like red meat and dark green leafy vegetables. It could be other deficiency too, like protein or vitamin C deficiency. Other causes may be that you have mercury fillings in your mouth or if you have some internal bleeding becasue blood can have a metallic taste. Hopefully the reason for your metallic taste in the mouth is just as benign as mine: simple tiredness and you are worn-out. Get some rest and eat healthily!

Researchers now believe the culprit may be carbohydrates.  More specifically, certain types of carbohydrates, including rice and pasta.  These carbohydrates have a high glycemic index (GI), which means the body needs to produce extra insulin to digest them.  Excess insulin causes the blood sugar to plummet, creating a hungry feeling.

You probably have a small blockage in your saliva glands (much like a kidney stone). When you eat, saliva production increases, and the blockage creates pain in the glands.

Usually the reasons we eat when we're not hungry are things like depression, boredom, for comfort, etc.\n\nIf you know that you're eating when you're not hungry, find something else to do besides eating (or a dormant activity).  Go out and ride your bike or take a walk around the block.  Play with the dog or some other ACTIVE activity.  If you're unable to get away from a dormant situation (i.e. doing homework), brush your teeth.  When we have freshly brushed teeth, we tend not to want to eat anything right away.\n\nIncrease your intake of water as well.  Especially since Summer is coming (or here for some of us), it helps keep us hydrated as well as keeps us having a somewhat full feeling.\n\nGood luck - my mom has yummy stuff when I go to visit her too.

because air builds up inside us. It happens if you eat quickly or talk fast because you aren't getting enough air or you are getting air randomly so your body doesn't have chance to use it properly. Then it gets stuck and it comes out as hiccoughs

there is a lot of sodium on them so you will retain water and feel bloated. also you will be hungray again soon because you haven't eaten any protein or complex carbs.

Yes it does, because your body thinks that you are eating and it creates acids to digest the food. But, if there is no food there and you are only chewing gum the acid burns through your stomach creating ulcers.

The stomach is very elastic-y and can contract as small as a sausage when you're hungry and there's nothing in it.  But once you eat and you fill up with food, it can expand like a balloon.\n\nI think what that statement means is that when you're hungry and there's nothing in your stomach, your stomach makes the growling noise cuz it's like messing with the air in your stomach by contracting.  But it's not a health problem, it'll just expand once again when you eat =)

your hungry cause you work out alot and your body needs or thinks its hungry. Try drinking alot of water or snack on healthy snacks like fruits rather then junk food.
