what I 'do' PMK myself. I like the way it addresses an ethos which more or less says 'take back control of not only your eating, but your life'.
I also have got back into some exercise; I'm lucky that I have an electric treadmill set up in from of a telly so I try to fast-walk on it for 30 mins, 6 or 7 times a week (that's 2 miles a day). The mere habit of doing it more or less every day means it's just something I 'do', no 'will I/won't I?' to consider. I am aiming to lose between 1 and 1.5lbs a week, too.
I have never been someone who gets any obvious body-sculpting changes when I exercise- that's a recognised scientific fact, btw! In my 30s (when I wasn't particularly overweight) I went through a phase of going to a gym every day; aerobics, swimming, cycling to work, 'healthy' eating, and although I lost half a stone in 6 months my body, essentially, looked exactly the same! No particular new muscle definition at all. I felt better and had more stamina etc etc so it was really good for me to have done it, and of course the mental health benefits of daily exercise are well-recorded.
I also used MFP to make sure I was on the right track regarding the nutritional value of certain foods. When you have to 'watch' what you eat, you need those calories not to be 'empty', don't you? I also eat veeery slowly now and aim to not be the first in the family to finish, every time! And PMK advises you to always leave something on the plate to prove to yourself you don't need to eat everything there. Regaining mastery of my appetite!
Anyway, I hope star comes back to this forum soon as there's such a huge wealth of support and know-how on it!
