Water, walks and weight

I've been doing a bit of walking lately - and drinking lots of water. Daughter H is trying to return her body to pre baby days and I am following behind in her footsteps. We are similar in weight and height so its easy for me to just copy her - and bless her, she doesn't mind sharing at all :)
It will be difficult for me to return to my pre baby days as age and gravity have kind of taken their toll but I have been assured I can undo some of the damages I have inflicted on myself.
My biggest issue is a lack of fitness. Working in a sedentary job and not being particularly exercise minded has resulted in a flabby body and very little muscle tone.
Before embarking on this weight loss journey a week ago, I weighed myself. I seldom stand on scales as I tend to be an ostrich where my weight is concerned ... as long as my clothes continue to fit, I am usually happy. But I don't like knowing the actual weight because it means I might have to do something about it. What I don't know doesnt hurt me ....
I weighed in at 85.1kg - the same as when the doctor weighed me a year ago.
Miss H is a great fount of knowledge as she searches for information at the slightest provocation and she was able to tell me why my weight has stayed the same for so long. And she has set an exercise regime with helpful hints and suggestions of what to eat so that I don't feel deprived.
But my task for the last week has been very simple - drink 8 glasses of water a day, every day. Nothing else was expected of me but I was encouraged to walk. Drinking the water has been difficult. I don't think I have achieved the full 8 glasses daily but my intake has certainly increased .... and, just quietly, so has my output!
And on the walking side, I have done two hill walks - very steep - and one long flat walk over the past week. I found muscles I forgot I had.
But, it has all been worth it.... stood on the scales yesterday and my weight was ... taa daa [drum roll] ... 84.1kg. Yahoo - lost a whole 1kg so feel inspired and motivated to continue for another week.
That's me on the right .... catching my breath after a steep hill climb while Miss H returned to the bottom to repeat the exercise. Maybe I will be able to do that too one day in the not too distant future.
