Thank you ladies for your quick answers!

I should have said that I went through the menopause 11 years ago

, yes, yes, I don't look it

but I'm nearly 60 !
So I don't think hormones are an issue.

I was raising the question of not eating enough because apparently when you eat less your metabolism slows down

, my physical activity is still the same i.e. non existant

apart from a fair amount of walking!
I am not obese just getting plumper and plumper and I don't know why!

Nearly dinner time and we shall have tomato / tuna salad

and to finish off the meal some fromage frais and fruit salad !
How's that for a healthy diet?
