Lost Six Pounds Recently

Weight loss is hard!  I never realized how hard it was for the first 30 years of my life because I was always one of those skinny chicks who could eat anything.  After four kids and thyroid disease, I'm overweight and I can't stand it.  How do you know what works though and what doesn't?  I wonder does phentermine work, do those weight loss companies work, which exercises work? How do you know?

I've lost six pounds so far but still have 20 to go.
