We started at about the same weight. I had maintained at minimum a 50 pound loss for a long time but, a couple years ago, illness and stress caused me to gain very quickly - like 3-4 pounds a week - for awhile. And that comes off very slow. I also developed high A1C (6.1). It didn't come down right away but after six months it was 5.2. Health first and the weight will follow. Focus on the BP and the BS. Get those down and things will be swimming.
