Any changes from the hcg protocol will have an effect on your weight loss. It is evident that Dr. Simeons has tested many food items and allowed the ones that will work in sync with hCG diet. For fruits, he has listed apples, oranges, grapefruits and strawberries. Furthermore, he states that “a tangerine is not an orange”. So it is pretty clear it is not a good idea to sway from the protocol or substitute for any fruits when it comes to hcg diet program.
