Hi Notts Boy,
Another voice of support here -- if you had excellent loss of 12 lbs, 9 lbs and 7 lbs in your first 3 weeks don't be too surprised that you've had a slight dip in week 4 -- it might well be more in week 5.
Also, mathematically I worked out that according to the calorie deficit women who require 2000 cals a day to survive are in deficit by 10,500 cals a week .... 10,5000 divided by 3,500 cals per pound of fat = 3 lbs per week.
For men who required 2500 cals a day to survive the calorie deficit is 2000 cals per day = 14,000 per week ..... equals 4 lbs per week.
So if you look at it that way you have absolutely hit target.
For most people on any "conventional" weight loss plan they would think that 4 lbs was BIG loss -- they would not have the reverse thinking that being on Lighter Life causes us to have !!!
Best wishes,
Sharon
