Am I eating to much if I look bloated after eating?

Today my stomach looked fine until after I ate a bowl of cereal. My weight was 228 but after eating it was 230. I know that is normal because when you eat you gain more weight. I look bloated though and could that be from eating to much? I ate a regular bowl or raisin bran but, I didn't drink the milk after eating the cereal. Now my stomach is like out there. It looks bloated. Should I maybe not fill the bowl to the top with cereal or what? Thanks for your answers.
