I definitely do. I'm about 70 lbs overweight (and that's after losing 35 lbs), and this is why I'm on the southbeach diet.
3 1/2 years ago I celebrated at Weight Watchers a 52 lb weight loss. I felt SO good about myself, but i was SICK and TIRED of weight watchers. So, I quit and put 15 or so pounds back on RIGHT AWAY. Like within a month. So, I started back up to weight watchers, but I couldn't get with it. So here I am...I gained back all but 2 lbs of that weight. Now, I've lost 35 again doing the southbeach diet. However, this diet is supposed to take the weight off quickly and I started it back in February. I only really became serious about it in June when I realized how quickly my birthday was approaching (that was my goal to have my weight gone by my dreaded b-day). I've take a couple weeks of from June 18th until now, but since June 18th I've lost about 27 lbs. I can't tell by looking at myself but others have noticed and I can tell because my clothes fit a LOT better now. I was actually able to fit into 2 pairs of capris pants this summer that I haven't been able to wear in 3 years. Last summer I couldn't even get them up over my butt (and I don't even have a butt) and this summer I got them up, buttoned, zipped AND I COULD STILL BREATHE!!!
Tomorrow is my 1st day off in 12 days and I told my husband I'm eating junk from the time I wake up until I go to bed. But Monday, it's back on the diet for another 12 days.
Once I get my weight off, I plan to do Southbeach M-F and then take weekends off. My weight is a life long battle.
