Wow, Sabine! Good luck on the challenge. There was a short period of time (around 6 weeks) in my life when I actually had to restrict my food intake for financial reasons. It was a little over 9 years ago. I had just graduated from college, and, while I had a job working at a university lab, it took the university a couple of weeks to process payroll so I couldn't get paid right away. I basically ran out of money and wouldn't get my first paycheck for 6 weeks. I lived off supermarket bread (the cheapest kind) and one bottle of Welch's strawberry jam. I'd make myself jam sandwiches, but I could only have two a day because I had to make it last. Needless to say, I lost weight. It wasn't fun though. It was very stressful.
