Oh, my I wonder if I can even remember all the things I have tried.
Way, way back in jr. high, I joined weight watchers with my mom. Back then you had to count how many foods you ate in each food group. (like you could eat 3 breads, 5 proteins, and so on) You had to eat something like 10 servings of fish each week and liver (YUCK!

) at least once a week. I didn't stay with it, but lost most of my excess weight by the end of 8th grade because a doctor prescribed diet pills. (no meal plan, just take one of these before breakfast

)
Throughout high school I gained and lost weight constantly. Most of my "diets" consisted of "got to much to do and too many places to go to eat" and surviving on a Snickers bar and a hamburger for the day (and usually we were all broke so two or three of us would split the hamburger!

)
As an adult I have rejoined weight watchers at least a dozen times. I have probably tried every different program they have ever had. Most, I really did have some success with; its just sticking with it.
Mother and I went to a doctor in a neighboring town that would prescribe diet pills and suggested that you follow the meal plan for diabetics. I lost quiet a bit but of course when I stopped taking the pills it all came back.
Once Mom and I tried a liquid diet called "the Cambridge Diet". AWFUL tasting stuff. Didn't even last a week.
I tried LA Weighloss--HUGE waste of waaaaayyyy too much money! Did not lose one flipping pound!
Tried Akins. Couldn't get past the first 3 days.
Me and a friend at work went to another doctor and had the staples put in our ears. Literally a staple in the center part of your ear (supposed to be like accupuncture). Worked for as long as we convinced ourselves it would work.

Actually did lose some weight though, probably about 30 lbs.
The most success I have had was using Slim Fast. I started out with nothing but 2 Slim Fast shakes a day, one Lean Cuisine for supper and water. I did that for about two weeks and then added in fresh fruits and veggies. After another two weeks, I started replacing the noon time shake with a low fat Subway or some other low cal sandwich or meal. And I walked every day up to 3 miles and worked out every morning. I lost about 65-70 lbs and felt great. Problem was, when I tried to eat "normally" (no slim fast) I started gaining it all back.
Then we (the same work friend and I) heard of a doctor that was prescribing diet pills. So we went to him and got the pills. Made me very nervous and anxious so I couldn't take them.
That was when I decided that I would stop trying to find that "magic cure" and just change the way I eat. My friend is still trying everything that comes around. Last time it was some kind of drops to put on her tongue???
