No idea if I'm in ketosis, I have 3 products a day (i couldn't manage 4, I'm not too keen on them!) I was very borderline as my BMI was 39.9 so almost at the point where you can't do SS! Do you think my body could have gone into starvation mode instead? I lost 9lbs in my first week, second weigh in is on Saturday and the scales look promising so far. I just am fed up of being hungry!
