It took me 10 months to lose 50 pounds but over 2 1/2 years to lose the last 30. It doesn't mean I was doing anything wrong per se, but I had to learn all I could about this process, which is where I believe educating ourselves can be a big factor in getting us off the diet roller coaster.
What I had to learn was this journey is one that I will have to be on for the rest of my life. It MUST become a lifestyle--in my eating and activity. It took me 3 1/2 years to lose 80 pounds but I am proud to say I have kept the weight off longer than it took me to lose it (4 years next month) and that is the first time ever I can say that in my 51 years!
You can do this!
