I am turning 50 this year. I was on Atkins in my 30's and I lost much faster then. This time around it seems I have to stick with the plan much closer and count every little partial gram of carbs (spices even) and exercise more often to see results. When I was younger if I sorta kept to the plan I would still lose. My goal is to be to my target weight by my birthday It could happen, I figure turning 50 is a downer but if I face it with a thinner frame it will not be so bad.
