I don't know much about either of the diets you mentioned.....I have tried ALMOST everything under the sun...LOL!
This year I have committed to doing it myself without any diet aids. Just calorie counting and exersize...and coming here to give and get lots of support.
I took some prescription diet pills once and lost alot of weight....but gained it all back and then some when I stopped taking them....cause I didn't learn any good eating habits......with my calorie counting I have learned to make alot of the dishes that I love in a healthier way so I can eat what I like....without going way over my calorie budget.....
I'm glad your here.....there is a subforum for almost everything...just look around and your sure to find something just for you! Check out the chicks up for a challenge thread too! It is fun...you can participate in lots of motivating challenges!
