Good responses from Janet and WereBear. I'd also add that since you appear to be close to your goal weight of 180, be aware that weight loss alone is not linear or the same over time. When you get closer to your goal weight, things typically slow down. Does this mean that Atkins is not working? No. It simply means that your approach is working and your body is starting to adapt to its optimum conditions. For some, it starts fast and is like a freight train, then it's not. Exercise frequency has nothing to do with what you're experiencing. Sounds like it's normal to me. Be well.
