Do something that will keep ur mind away from food. Sip some water too
Sorry but that is NOT going to work. Water has no calories... it's just fluid. When you're hungry what your body is seeking (or brain for that matter) is calories and source of energy... that source is typically primed for sugar rich foods since they are high in glucose and easily digestable. So drinking water is NOT going to fill you up.
You really need to understand the physiology first before you start to do a trial and error approach..., it can be devastating if you are not careful.
Sip water to stay full . read a book. Or even better>> workout. Working out relieves stress. Try going for a run to clear your head. & don't keep junk food in the house.
Fruits, veggies and lean meats are your friends - Stay away from processed stuff
Eat low glycemic foods in small amounts. Nuts, whole wheat, animal proteins... etc
