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"?

    If it's constant and stable from birth, it's probably genetic. Enlarged facial bones in acromegaly can result in big head appearance - this happens in adults. Fat deposits in Cushing's disease give an appearance of "moon face."

  • It depends what it is. I mentioned only 2 of many possible causes in my above comment. It's unlikely someone her will guess what it is just from a simple description. If you are concerned, visit a doctor who can give you an exact diagnosis and tell you what can be done.
