I was thinking along the lines of what saef said.
For me these are two different things. I retain fluid after eating salty and/or processed foods. Puffy hands, face, eyelids.
My abdomen bloats when I eat unwisely. For me that's grains, potatoes, ice cream ... That's like balloon belly with gas I can't get rid of
My waist measurement actually gets inches bigger and I feel uncomfortable under my ribs.
