Honestly I hadn't done much research before I got the band n started looking at utube video n looking up stuff on line but not too much. I thought the band was going to make me feel full. Like when I were to serve myself 1 cup of food I thought I'd only b able to eat like half n b able to say whoooo I'm full n physically can not eat any more. I have now realized that the band is not here to make me full but instead it's supposed to make the food I do have last longer. It's a lot of hard work or has been for me n lots of times I feel like I'm still on a diet. Im having to track my calories, choose healthier foods to eat, n have been working out a lot. I've only got I fill so far so maybe when I get to my goal weight, I won't have to track any more. Choosing healthier foods n working out will have to b a part of my life forever but hopefully with the band, tracking will have just been a tool to help me become healthy.
