Walking in Yorkshire, England

I had a lot of photos again for you too see. But since I did not uploaded it until now I can't show to you more. We went to Yorkshire today here in England. Oh yes, I am still in England. I am almost three weeks here now. We had a lot of walking today in York. Is walking a good way to lose weight? Or do I need to take some fat burner to burn my excess fats. I am really desperate to lose my excess weight but the bad thing is i love to eat while traveling. Just like today I ate a foot long toasted submelt. It taste good with vegetables and ham in it!! I promise to share more photos when I will be backed home!! Cheers! I am really having a good time here..Thanks to dear friends for everything!!
