LMP!
I vote for good ol' fashioned eating right any day. I guess I've never done a fad diet, so maybe it's not fair of me to write them off, but I think you need to find something you can do, well, forever. If you poke around the Maintainers forum, you'll see that maintenance looks a lot like losing, just with a couple hundred more calories. If you make big changes to lose, but then go back to your old ways, the weight will be back on before you can say, "I'll take two pairs of skinny jeans, please!"
I've never looked into the South Beach Diet, but I think it is similar to what I do anyway. "Good" carbs (whole wheat flour instead of white, brown rice instead of white), lots of veggies, lots of lean protein. And in reality, I have cut back on bread, rice and pasta quite a bit in the last few months -- when I do have them, they take up only a small part of my plate.
I highly recommend tracking what you normally eat in either a phone app or online (I use myplate at
www.livestrong.com and I've also used fitday.com). Even if you aren't inclined to use calorie counting as a weight loss method, I think it's a great way to see what you're actually eating every day. I did this about 3 weeks into my weight loss efforts, I DID NOT want to count calories -- I just thought it would be interesting to see how much I was eating and what my carb/protein/fat balance was when I simply tried to "eat healthy, eat smaller portions, and snack less."
Well, I think it lasted about 1.5 days. When I realized how much I was eating, and that it was about 90% carbs, I started calorie counting. It works for me because I like numbers and measuring and adding and breaking stuff down, and also because by controlling my calories for a day or a couple of days, I can have treats, like ice cream cake on my daughter's birthday (and for two days after -- hooray for leftovers!).
This entire site is such an incredible resource -- take some time to poke around all the different forums and see what people are doing. Don't neglect the maintainers forum -- I found it so helpful to read there (especially the stickies) to prepare myself for maintenance. Cause I am not going back!
