I'm turning 40 in May. Last July I was going home on a city bus and there were no seats so I had to stand. A lady kindly offered me her seat as she thought I was pregnant. That was my "ah ha" moment. I am 5'8" and weighed 206 lbs. In 8 months I've lost 56 lbs and all I did was cut portion size of meals, and eat less junk ( I still indulge from time to time). At first I was really pleased with my weight loss but now, I seem to still be losing weight and not hitting a plateau. I now weigh 150 lbs. Should I be worried?
