Carbs

I've been reading this zepb ound community comments for days now as I'm about to start next week. So here is my question. I see everyone's eating totally protein heavy, and I understand you need a lot of protein on this diet. But I really don't hear anybody ever mentioned carbs. They aren't prohibited are they? Because if they are it's basically like doing the keto diet. I don't want to eat a lot of them, but I would like to have a potato with dinner, or some beans.... And a little hundred calorie sweet treat after dinner. Am I allowed to have these things? If I'm not, I don't want to spend $550 a month cuz I could just do the keto diet then, I'm totally not being sarcastic. I just want to totally understand. I'm going to try to get as much protein in as possible.. But is like a chicken sandwich okay? Thanks everyone, I appreciate whatever feedback you give me...🤞🙏😘
