Soft calorie syndrome

I have been asking around for "band friendly" receipes, and have found some helpful advice. Then my hubby goes: You can eat a full meal at dinner, do you need a fill? So I started looking around.

I can not eat Breakfast many days, can eat 4 oz at lunch some days, and can eat a lot for dinner. But most days I eat soft foods, Soups, blended items and such.

So how do you know if you need a fill if you follow the tight in the morning open in the evening pattern? How do you know if you have the soft calorie syndrome in this situation?
