I lost two stone -after I retired 2 years ago at 62 - in about six months. I was able to walk more, eat healthier, have smaller portions, little alcohol but lots of water, or miss meals.
I now regularly watch my weight, when I go on holiday, to friends for a meal, recently a family wedding etc, I find I put on a couple of pounds but within a week it is gone.
I have definitely changed my eating habits.
I am about 5lb over my ideal weight but as I am now a size 12 I am happy.
I believe it's rubbish that you cannot loose weight over 50, it's just that you are used to a way of life which is harder to change. I was a size 12 up until my 40's so I just kept reminding myself of that fact!
I have slightly raised BP and have low meds. (My mother had very High BP, --undiagnosed which led to heart damage). My cholesterol is fine.
BUT
a routine blood test revealed, osteoporosis, early onset arthritis, (which I was having symptoms of) and pre type 2! And a recent urine test showed blood and protein!
My GP believes as my weight and lifestyle are good, the pre type 2 is probably genetic (my Dad developed it in his 40's and he was not overweight.)
Life eh??
