I am six years post menopause and I did lose some weight right around the time I stopped having my period. I had started cycling about 2 years before this and steadily lost about 10 lbs. Then, after the periods stopped, I lost about 5 more, from upping my mileage. I have to be a lot more careful now, but I still eat plenty of good things. I go out to eat a lot.
But, no dessert, except for special occasions, no junk, ever, no cookies, cake, etc. in the house. No soda, white bread (OK, once in awhile), fried stuff.
I exercise 5-6 days a week. And, that has to be varied or my old body gets used to whatever I am doing and starts gaining.
Lots of fruits and veggies, lean protein.
