Hi and welcome Raquel. If you stick with LT 100% you will lose all the weight that you want to. Really try to stick to it 100%, you will get to your goal so much quicker if you do. I think 3lbs a week is realistic and some weeks I bet you will lose more, which is always nice. Get drinking that water and watch the weight drop off you!
Many thanks miniB , im in the right frame of mind, i know it will be tough, but roll on the next 16 wks, your weight loss is blinking fantastic, well done you must feel amazing, i cant wait to feel good
