I may be temporarily moving back to London for a project, but really it's just part of a bigger preoccupation with the things I look forward to eating when I travel internationally. I'm not talking about Michelin-starred restaurants, or under the radar family owned places. My tastes are quirkier.
What I ask people to do is to get on the scale every day. Yes, every day. Write down your weight each day and average it out over the course of a week. This keeps you awake and aware to what is going on.
