Q: What is the reason for constant hunger??? I am so mad when right after I eat breakfast, lunch, or dinner, I get hungry really fast right after and I am forced to eat eat eat. Is there a reason for constant hunger? Can it be stopped? If it can be PLEASE TELL ME HOW!!!!

A: You'd need to tell me more about yourself before I can help -- age, gender, weight, physical condition, physical activity level, current diet (what and how much you eat in all the meals). Post back with all the info and I should be able to give some advice.

In general hunger arises from shortcomings in your diet. Eating a high-carb/ low-protein diet (very common) could be one reason, especially if most of the carbs you eat come sugary stuff or 'empty foods' like white bread or white pasta. Another reason could be constant undereating -- this could be because you simply eat too little or because you are very physically active and seemingly normal portions are actually not enough. The latter is especially common if you are a growing teenager.

But, as I said, if you post back with a lot more detail about yourself, your physical activity level, and your diet, I'll be able to give more specific advice.
