Fasting is not a diet in itself, and your calorie restriction could have been self-defeating. You did not eat for 50 days and then expected your body to live on short rations. It is very likely it is conserving everything you give to it. You will only start losing weight again when your body has recovered it's stores and is safe from starvation. After a long term fast that is certainly one of the goals of the body. If you haven't finished detoxing it will continue that process at a lesser rate while recovering if you are eating correctly but it needs to rebuild it's stores before it will continue with your personal goal of weight loss.
Eat according to your hunger. Don't be set into a caloric limit, don't even be set into eating three meals a day. If you wake up and you're not hungry- don't eat until you are. If you still feel hungry at the end of a meal don't stop eating because you've eaten your alloted number of calories, be satisfied. I don't know what the refeeding plan you are following is, I hope it is very high in raw foods though because if it isn't and you are eating too much cooked or processed foods that could be leaving your body 'wanting for more' also and if it's not getting enough it won't be shedding pounds anytime soon.
