Broxi, I was worried about this exact thing when I started SW, I though well ok this is great I am still stuffing my face and loosing weight, when will it stop? it must stop soon? I was dreading the weight loss stopping and having to look at my portions.
What I did not factor in though is that my tummy has shrunk and so has my stomach, my body has done the hardest work for me, I cannot eat the quantities I used to even if I wanted to.
This was proved to me beyond a shadow of a doubt recently, we went on a holiday of a lifetime to NYC for 14 days, I had planned this for a year and decided long in advance that, whatever the consequences, SW was not coming with me, I had two weeks off SW and ate loads of yummy things, the biggest surprise though was that I could not eat as much as I wanted or as much as I would have before. Your body changes as you loose weight and follow the plan, and you will find at as you get smaller the amount it takes to fill you to full will get smaller and it WILL become easier.
As an aside I gained 12lbs in NYC in 14 days, there is a picture record here if you want to see but don't look if you are faint of heart
10 of it gone now though and I am aiming for my 5 stone award for Christmas.
