Many people (including me) believe we have set points along the way. These set points give us those plateaus as the body adjusts to the new weight. It's like a thermostat, and soooo annoying!
I have about 4 set points, and noticed in my years of dieting
that they also 'set' on my journey up the numbers
If you stick to 790, it will continue to come off...in fact, there's a good chance that you are still losing fat, but your body is jiggling about with the composition and replacing with water or whatever.
To get me over this point, and to give me something to focus on, I changed the times I had the shakes and included a little different exercise. Just some walking will do. I did this to wake my body up as I felt it might be in a rut. Hoped it would forget what it was previously doing and sort of 'shock' it into action. At least it reduced the boredom level.
Can't remember whether it worked, but I do know the loss started again at some point.
With ever other diet I never managed to get those last few pounds off (okay...last 3 stone
). I managed it with Cambridge, as the plateau didn't go on for weeks and weeks until I gave in.
