Hi Susan, and than you for the welcome
I think I'm going to go for the whole foods/super foods option combined with biking to work 3 days each week (it's about 40 mins each way, and I hate public transport anyway). It's just dragging myself out of bed to do it when it's raining - London winters are WET and MISERABLE. It was still dark at 7.15 this morning! I do have weights at home which I like to use, so it's mainly finding a cardio substitute when I can't face the bike.
Foodwise, it seems to be the easiest for me to stick to, as I don't really eat much junk food - my main trouble spot is when I'm busy (I run my own business, so that's pretty much all the time) and I grab a sandwich from a shop. I don't do fast food, but "gourmet" sandwich shops don't seem to be all that much better. Portion control is a bit of an issue with me, but I'm just as happy to substitute veggies and low-fat dip for bread and hummous. Also, my job involves a lot of socializing (I work in the music industry, so that means lots of late nights at concerts with everyone drinking alcohol).
So I think I'll be needing a lot of diversion!
