I dont really class what I did when I lost 3stone a diet as such, I counted calories using MFP and lost 3stone. I ate what I wanted, when I wanted in moderation and increased the amounts of veg/fruit. I kept on increasing my activity levels, but didn't over do it.
Due to various factors, I put the weight back on, but using MFP just wasn't working for me, novelty wore off maybe? So decided to join SW for a different approach, and thought the emphasis on eating plenty of food, but the right foods, so not feeling hungry following the plan fit the attitude I have toward "dieting".
