A bloated tummy in an otherwise slim person may also be a sign of food intollerances.
Google Celiac / Coeliac and see if this could apply to you. If so, you could ask your doctor for testing / do an elimination diet.

Consult with a dietitian and/or nutritionist on proper foods and portion sizes. Use Google search too.

It's your will power.
