There is a Hollywood actress named Renee Zellweger who recently had to put on 40 pounds for a movie. She is normally very thin, an American size 6. She said that she counted calories-- made sure she ate 3,000 calories per day, whether she felt like it or not. She said that she had to keep eating long after she started to feel full... to "force feed" herself is how she described it. But it worked. Some of us feel full far more quickly than others do, and we are the ones who are skinny. Whether you feel full or not is like a trick that your mind plays on your body. It could be that you feel full *even though* you haven't yet had enough to eat! In that case, of course, keep eating. Also, it has been shown in studies that rats will eat a larger quantity if they have a variety of foods to choose from, as compared to just one kind of food. You may find it easier to gain weight if you dine buffet-style, at restaurants. Or, just make sure that you are eating many different kinds of foods at home... it should also be a balanced diet-- don't forget the protein and vitamins! But I agree with Molly, many men out there love & prefer skinny women, even very small-busted women. Similarly, women don't mind if a guy is very skinny. You WILL find your perfect match!
