people who tried the cabbage soup diet only please!!tommorow is my last day..day number 7 and now i’m scared that i will gain it all back. how do i slowly start eating normally again? is this good?

breakfast: fiber one cereal
lunch: fiber one cereal and a fruit (or i might have a sandwich)
snack: activia with my own fruit put in
dinner: steamed veggies and grilled fish dipped in 1 tbsp (ish) or light mayo

if i eat nicley like this can i keep the weight off? and i’ll have like a few hundred calories a week of junk food for right now. (about 200)
