Oh and not having a car, and not driving everywhere...thats going to be wierd for me. But I am hoping all this walking will help me loose some extra pounds...**wishful thinking**.
Well, I gained a some weight at first trying all the new chocolate bars and snacks and stuff. Once I got over that, though, I have been losing weight - not from walking, but from cooking at home instead of going out to eat all the time. There aren't many places to eat in our little village in the country, which has sort of helped me control my weight, but I guess that won't be to your advantage in London, especially if you like Indian food.
But, without Taco Bell, Taco Bueno, Taco Cabana, Chick Fil A, Whataburger, Braums, Sonic, and most of the other fast food options, plus all the walking, I'm sure you will lose some weight! (Unless you just hang around McDonalds, KFC, Pizza Hut, or Burger King all day... lol).
