Hey Charl
I know exactly how you feel. A naughty sneak on the scales has showed me about 2.5lbs down this week and WI is tomorrow. I think to myself, I have so much weight to lose, 8 stones, and I can easily achieve 2lbs a week weight loss on other plans, have done in fact, several times. We are limiting our calories so much why are we losing so little weight?
The only thing that is different with my life now compare to when I have dieted and lost 3lbs per week on other plans, is that I'm now totally sedentary. Most days I never leave the house and I live in a tiny matchbox sized flat. In fact, when I weighed in at the pharmacy on Saturday and he noted a 2lb loss he advised me to start exercising and I think he is right.
It's true we are all different, made different and lose at different rates but at the end of the day, ketosis or no ketosis, calories in vs calories out is what it actually comes down it - it says as much on the bag "maximise the calorie gap". You need a calorie deficit of 3500 to burn just a single pound of fat. If like me you are sat on your butt all day then basically the only calories your body is using are the ones that keep your body ticking over so adding *any* form of activity to my day would have an impact on my losses.
I have no idea how active your lifestyle is Charl but it's worth taking into consideration. In fact, it would be interesting to know just how active all of us are day to day and perhaps that may also shed some light on why some people have consistantly higher weightlosses than others. People who work and run after children all day are bound to burn of lots of calories compared to those who don't and/or are housebound.
Just another thing to think about. Well done on your losses so far though, you've done amazingly well and you should be very proud of that
