Fat Burners

Boy, we just finished supper and am I full. My husband and I get done with eating and we seem to always say, we ate to much again. Why is that? It seems to get increasingly worse with age. We are trying an exercise program, but must get our eating under control. I know that there are fat burners, diet pills and other types of diet methods available. I guess a person has to do what is best for them personally.
