What do you do when your family keeps telling you to eat while you are on a diet?

The most common thing you hear when you start a diet is...

It seems like it’s okay to just do it for today.

I found it especially difficult to refuse when family members recommend it.

I am curious about the practical ways you handled situations like this.
