Am I food-shaming my brother just by declining a second helping?

I'm trying to watch my weight as I'm slightly overweight and want to lose a few kilos.

My brother is a bit immature for his age. He's 35.

I had dinner with him the other night at his place. He had a second helping of soup and asked if I wanted more.

I said no and he started yelling at me that I was food shaming him cause he had a second helping.

All I did was say no and that I was full.

Immature right? How am I food shaming him by not wanting more food.
