Trying to understand how this would occur - why would someone's face be fat (either in general or compared to body) when the rest of their body is toned/lean/skinny. Ive observed this personally for years and in others -
I read that excess sugar can cause excess collagen in face, thus causing the "bloating" look. What else might be the cause of a disproportionately fat face/neck when the person appears skinny everywhere else?
If they consume a high amount of one food (for example nuts)- could this be a permanent state of allergic reaction?
How would one narrow the factors to determine what is causing the "face fat"?
