Well done! That's remarkable.
I'm 60 and have tried lots of different diets over the years. I was 9st when I got married in 1980, then after having2 children, I weighed 11st. I stopped smoking, went up to about 12 1/2 st.
My heaviest was 16st 2, size 24, a few years ago. Since then, I've been 12st, and up to 15st 5 again last Monday, when I joined Slimming World. I've lost 4lbs so far since Monday.
I go to Zumba 3 times a week (an hour each time), and I do Salsa dancing. My BP is normal, so is my blood sugar. Cholesterol is low, and the only tablets I take are antidepressants, so I'm not as bad as I might be.
Keep up your good work, you're doing marvellously well
