The idea when you are eating is to eat less, suppress appetite, and lose weight.  We take natural appetite suppressants all the time, and with the exception of water, they cost money.  Even chewing gum, which is a major natural appetite suppressant, you spend a few quarters at least.  But you can also suppress appetite with foods.  For example, you can suppress appetite with almonds.  It would be better if you like them.  But apparently a study showed that women who ate at least 2 servings of almonds per day ended up eating less throughout the day. 

Likewise, apples, a medium sized apple, has tons of pectin and fiber and will naturally suppress your appetite.  Pine nuts are highly useful, and they are actually used in natural appetite suppressant pills because of this.  But a big one that I have noticed is actually eggs.  Eggs you eat one and you are full for a few hours, just one egg.  Yes, they are high in cholesterol with the yolks and all.  But they are also high in protein, and they fill you up with small amounts for quite a few hours, which is not a bad thing.
