Hi Rebecca and welcome!
Good luck with your journey on the regular program. That's the one I started with and, if you follow it wholeheartedly, you can expect to lose weight at a steady pace. You'll probably lose more quickly in the beginning and then a little more slowly as you get closer and closer to your goal. That's great that you're working out with weights and aeorbics! The exercise will definitely help with your weight loss as well as keeping you toned and fit. Make sure to monitor your blood pressure closely as it may start coming down fast and your meds will need to be adjusted accordingly. I was able to get off 2 blood-pressure meds the first week I was on the regular program so I know it can work great for others dealing with similar issues.
I liked the fact that you said you're not in a hurry to lose the weight. That's a very positive attitude and if you just simply focus on getting healthy, the weight loss will come because that's the body's natural state. That's the best thing about the McDougall program...it's about obtaining optimal health by eating the best possible diet, moderate exercise and a healthy lifestyle. Everything seems to just start falling into place
