Find What Works For You!
I would say it all depends on the person. We are all different. For me, I had a lot of weight to lose, so, I stayed at 20-25 carbs a day for close to 2 years. Even now, and I've been doing Atkins for 2 1/2 years...I still stay primarily at 20-25 carbs. When I do add more carbs, its in the form of extra veggies, a small amount of almonds or low carb/low sugar yogurt.
Basically, what I'm saying is, you have to find the amount of carbs that works for you. Some people can eat 60 carbs a day & still continue to drop weight....some can't. Its all individual. The only way to find out, is to read the book & start slowly moving up the carb ladder as Dr. Atkins suggests (OWL). You will find what works for you.
You CAN do this!!
All the best to you!!!
