I started Atkins 3 weeks ago. This diet was successful for me in the past, however this time it is different. I know my body is different, I am in my 50's now and losing weight is harder than ever. My first weeks on Atkins I was successful losing 15 lbs but this week I gained 4. very disappointing as I did everything the same.I believe from reading some posts that I may not be eating enough. My only carbs come from vegies and 4 packets daily of sweet n low for my tea. I'm going to track and see. Hopefully my weight loss will resume.
