Help!  I seem to be resistant to weight loss.  Tried serious exercise and diets with NO RESULTS.? I have tried South Beach, & Weight Watchers - on both lost 5 lbs before I stalled out.  I worked out with a trainer for 3 months & lost 5 lbs (at the same time I was South Beaching).

I did (and still do) weights -light weights high reps - 2-3 times a week.  I do cardio 2-3 times a week - have tried several techniques.  Total gym routine is 4-5 times a week for at least 1 hour.  I tried running, builing up to 8 min at a stretch at one point.  Then at my trainers request I did only fast walking 3.5 mph on the treadmill at a steep incline 5-7%.  Now im trying intervals on the eliptical 1 min of 70-80 rpm, followed by 2 min of 50-60 rpm at low resistance.

NOTHING IS WORKING, I STILL WEIGH THE SAME.  I am 5' 2" & weight 210, so im not looking for perfection, just results.  I have been tested for and ruled out thyroid disease and diabetes.

Please dont suggest I purchase anything, funds are limited, except books, cuz there is a library.

Thanks for your help!  :)
