Hi Jennifer7.
Have you lost any inches? I want to lose about the same amount as you do. My loss has been slow in pounds, but I am losing inches. In 5 months I have lost only 16 lbs, but I am down a size in clothes.

I get frustrated with slow weight loss also, but as long as I am "shrinking" I will stick with it.
When I have a loss, I will gain it back and lose it several times before it finally stays off.
Don't know why it happens. I stay around 20g of carbs each day, sometimes less.
Please measure and pay attention to the inches. The scale makes me crazy.
Good Luck!
