I have lost 4.5lbs in 2 weeks which is mega for me. I have under active thyroid and weight loss is normally slow for me. In the past when I have done SW and WW I have only managed to lose half a lb a week and it was a struggle.
I am finding the fast days quite easy which surprised me because I am normally a grazer. I am having a green juice for breakfast that I make with a green apple, celery, cucumber, kale, a half a banana, a couple of blueberries and a bit of fresh ginger and a squirt of lemon juice...I add a bit of water so that it's not too thick. I have the same at lunchtime, and drink lots of water, lemon & ginger tea, and peppermint tea to get me through the day. I am then having either chicken or fish with a bit of veg for tea. (Yesterday my calorie total was 460)
I have always ate quite healthy but since doing the 5:2 I have more energy where as before I was always tired and very low energy. I also feel more alert and the only negative thing for me is that on fast days I don't sleep very well, where as I normally sleep like a baby for 9 hours per night.
