Hi Scarlett, and good on you!
Yeah I'm really glad I decided to start to look after myself again and I'm not only slimming down (was over 102 kg's now 94.6- not that I'm counting) but I'm actually becoming the fittest I've ever been in my whole life. I have been fairly physically active over the years and had a bit of success running as in coming first in my footy club dash around the tan several years ago now. I think what happened is I was so busy with work commitments my lifestyle became really bad, no time for exercise, or eating properly, let alone enjoying life, so I left my profession and took up a new less demanding career, less money but so much more value from life.
I've found through enthusiastic daily exercise, cutting out added sugar, especially simple sugars, and added salt, and recording everything and adding up and tracking calories daily I'm really flying along the path to a healthier me, but as you say- it helps not going at it alone, and I have had some great encouragement from this site!
My greatest joy has been realising that there's no such thing as over the hill or too old. I'm similiar in age to you and have learnt that many people in my situation have gone on to become super fit an even gone onto do things like beat super fit teenagers in running races, etc!
So again- good on you! I know you can do it.
