I have lost 4 stone 4lbs since the beginning of november on my diet of 500 calories for 4 days water fasting for three days. I really expected to have lost more than that tbh so im a bit upset, i was 16 stone 4 lbs now im 12 stone at 6 foot 2, i want to get down to roughly 10 stone which is where i used to be before starting certain meds. I think the water fasting isn't helping and my be hindering my weight loss so im going to cut that out. I have read in to the keto diet, not sure if i want to start it or not.
I hope you do realize that you are seriously hurting your body this way.
