Dinner while on a diet

I'm on a diet but I'm craving something for dinner, so I'm worried.

I'm trying not to eat carbohydrates, but since I'm not eating them, something...

I keep feeling empty, so it's hard to endure the hunger.

Even if I eat things like nuts, the emptiness and hunger seem to only last for a moment.

So, I think I end up eating more because I keep trying this and that for no reason.

How do you manage your evenings while on a diet?
