What ? that is really weird, what do you mean you didn't get any more rating ? Like you completed the next level and it never gave you stars ? If that is the case, maybe you didn't balance the plate, you need to have as much greasy food (the food to the left) as healthy food (the food to the right), you can see the balance in the left corner (I am assuming that's what went wrong because that's what my sister did wrong)
