An average is 1/2 to 2 lb (1/4 -1 kilo) per day. Or 30 lb (13 1/2 kilos) per month.
But dont get hung up on the scale weight. While you are on the diet and taking HCG you cant not lose fat, inches and weight on the scales. If your weight does not move on the scales for a day or two you will still be losing fat off your body – all over the body.
