I was thirsty, too, even though I drank a lot of water at my friend's place in the morning and again after the Matan lecture. Actually, by the time I picked up my new glasses in the center of town I was hungry but wanted to get to the bus station first. Many diet experts say that exercise increases metabolism so that what you eat post-workout is worth fewer calories. Besides that, I was afraid that I'd feel "too heavy and satisfied" after eating to walk.
I walked the kilometer or more with a very heavy backpack strapped to my back. I needed to buy myself some water in the discount supermarket near the bus station, and I figured I could save money by buying low-fat cheese and veggies. Also, I need some hat "yarn." I'm sure you've heard that shopping should never be done when hungry, couldn't make a decision, so walked out of the yarn store empty-handed.
At the supermarket, I cracked a six-pack of water, just taking one small bottle and then headed for the cheese. Each little package was over ns10 and chock full of salt and the sort of "milk solids" I don't like, so I just paid for the water and headed back to the bus station.
Cafe` Net was my first stop. I checked out their salads. NS21 for a big bowl and had them add tuna (sans mayonnaise,) a hard boiled egg and some olives.

Delicious! Half was eaten in the shop and the other half on the bus. I couldn't have made a more satisfying or less expensive lunch on the go.
The most difficult lesson I've learned from this diet is that you have to eat to lose weight. OK, maybe I should have totally ignored the dessert at the wedding, but I only polished off the fruit part, nibbled at the sorbet and I did ignore the chocolate cake...
