I've been using it for 2 weeks now. Weighing myself after a pee in the morning i've went from 76KG to 72.4KG in that time which i know probably doesn't sound much to some of you but i'm only 5'7" and thin boned so a good couple of stone overweight. Roughly dropping 1.8KG per week which is nice to see going down rather than up for a change. Probably mostly water so far but it's a start.
It's not just eating it that's doing it though it's the routine, apart from one night i've cut out all alcohol and almost cut out snacks (have had 3 grab bags of walkers sensations in that time). Before i'd eat all day long and would easily go through 20-30 units of alcohol a week.
I have 3 months worth stocked up to make sure i'll stick to it. After that hopefully it will have got me in the habit of automatically balancing my calories eaten and used. Previously i'd happily munch on 2 grab bags of doritos and a whole cheesecake in the evening and whatever other snacks during the day without thinking about it other than mentally (wrongly) cancelling them out because i'd be on the treadmill in the morning.
How did you get on?
