These are the only recommended vegaetables I have not found others that can be added but of course if you want to experiment that is a personal preferrance. I think it would depend on how much weight you have already lost and how much more you want to lose. I followed the protocol to a T because I wanted to reach my weight loss goal in a set amount of time. If you stray away from the recommend vegetables I would just watch my serving size closely and I would also monitor how it affects you....sugar level, energy etc and I would also monitor if I gained or lost more weight.
The recommended vegetables on the protocol that I followed are these: Asparagus, Beet-greens, Cabbage, Celery, Chard, Chicory, Cucumbers, Fennel, Green Salad, Onions, Radishes, Spinach, and Tomatoes.
I also purchased both of the Hcg Cookbooks that are available because I tend to get bored with what I am eating and those 2 books have helped me tremendously too. To all your weight loss success!
Where did you buy the HCG cookbook?
