I think also what helps is finding what works for you.
I started this counting calories- after just over 20 lbs my loss has stalled. Finally spoke to my doctor she recommended south beach. I've looked it over and figure I can do it. I started yesterday and I had a HUGE headache yesterday but today am feeling much better.
If you are currently doing something you feel doesn't work then I suggest trying something else
Good luck! Don't give up!
