I have always been overweight. I lost almost 50lbs (8yrs ago, when I was 21) with slimfast and cutting back on carbs. I gained it back and then lost almost 30lbs with Weight Watchers (6 yrs ago). Gained all that back, too. Then I started a diet where I cut LOTS of calories and walked every day. I was doing great, then found out I was pregnant (2yrs ago) :)
Now, I am bigger than ever and am ready to start that low cal diet I was doing so well on.
