Congratulations on your weightloss so far! While there are many who are really happy making Atkins their WOE on a long term basis, I was also one who was looking for a WOE which would focus on a combination of healthier fats, whole grains and fresh fruits/vegetables. I am also focusing on lowering my meat consumption.
I started SBD at 232 pounds, very close to your current weight. I decided personally, to complete a clean phase 1 and then move on to phase 2 and not eat anything off plan for 6 months. In those 6 months I successfully dropped 40+ pounds. Some weeks I would have no loss at all, but just stayed on course for the 6 months. I feel it was a good decision for me because I avoided panicking when the scale didn't move.
I moved into maintenance last October when I became less vigilant with off plan foods. I'm happy with that and intend to start again full force after my family leaves tomorrw. I know that all I need to do to get back into weightloss is to follow the plan to a tee.
1. Staying on P1 for an extended period of time is not recommended due to the boredom factor. Many beachers follow what we call phase 1.5 where we limit grains as we find what works for our own body.
2. We have lots of successful vegetarians here at the SBD forum. I am working towards that. For me, I read labels for the vegetarian substitutes and make sure the ingredients are SBD friendly. I avoid products which use potato or corn startch and make sure if rice is added that it is brown. I also find that some products are lower in sodium than others.
3. I personally don't count protein/fat/carbs. I concentrate on portion sizes and avoid overeating anything. I do measure nuts and cheeses because they are very easy to overeat which really bumps up calories.
4. I very rarely eat potatoes and I try to limit my breads to the sprouted varieties, Ezekial products being top on my list. I eat whole grains but watch my portion sizes there, too. I don't eat oatmeal at all because I've found it a trigger food for me. When I eat it, I just keep eating and eating. Many others eat it successfully every single day.
5. Your salad dressing sounds like a good choice. I have 4 or 5 dressings which I enjoy and again, I read labels. My criterion is that the dressing uses a healthy oil and does not have added sugar. I usually have 2 salads a day and add 1 to 2 T. of dressing to each.
The most important thing I do is check in here every single day. I find that I am more thoughtful of my choices when I communicate with other beachers every day.
