Those are the vegetables you are allowed on the protocol. If this is the first time you are doing HCG than the advise would be to follow protocol first. You may experiment with other vegetables but I would not do it on the first round. When you experiment, try one new vegetable every few days. Some may stall you and others may make you gain. So when you experiment, be prepared for that. And because one vegetable works for one person does not mean it will work for you. Each person's body is different.
