Please note also that lean means are fine if you prefer them but you need about 65% fat in your diet to do Atkins correctly. It is a high fat diet. I have seen a HUGE difference with weight loss slowing down since starting peri-menopause. Hormone changes create havoc with weight loss so that may be part of it. But here is something to consider. If you lift weights and have been doing so for some time. Your body will weigh more than the weight charts say you should for your height because you carry more muscle than the average five foot woman. I have talked to some very fit women who lift regularly and they tend to carry 10 pounds more in actual weight because they are more fit. The muscle is just denser. Plan on losing your weight over several months or so since you are so close. If that is the case the change from week to week might not be noticable. Better to weigh monthly and use a tape measure, not just clothes.
