I'm told I became fat

Both my mother and grandfather told me that I became fat. Its reason must be increasing amount and times of eating. Lately, I have to stay late at university. I usually feel hungry when I leave the university. Then, I drop in at a restaurant. After reaching my home, I eat dinner prepared by my mother.
So, I usually eat meals four times!
I'll make it a rule to avoid eating on my way home to keep fit.
