Just came back from a week's vacation, which was great fun. Over the past year and a bit I've come to dread vacations a lot less. At first, I was more pissed off about the lack of good eating on vacation than I was happy about going on vacation at all. But now I've come up with some strategies that I can live with and thought I'd share. I'm sure my free advice is worth every penny. :D
1. Stay in a place with a refrigerator. Several times during the week we had breakfast in the room rather than at a restaurant; and once I got take-out from Whole Foods. Saves money, promotes variety, helps you to stick to whatever your plan is.
2. You don't have to live at the gym. I only went to the gym once on the week's vacation, but I kept BGs in check by omitting some snacks and doing lots of absorbing activities that required walking or otherwise moving. Kept my mind off food and was very entertaining and a nice change-up from the gym routine.
3. Bring your own snacks for the plane and other places you can/want to bring snacks. I carry jerky or nuts around quite a bit.
4. If you're going to splurge, make sure it's worth it. I had cheesecake once, a black-and-white-cookie once (my favorite!) and Cuban food once. All totally worth it. Other than that, I stuck to egg breakfasts, chopped salad with dressing on the side lunches, and plain protein item with two veg dinners. If I hadn't splurged at all I would have felt resentful. As it was, it felt like a good balance.
Not only did I have a great time but I stepped onto the scale after my vacation at the same weight that I was beforehand. That has never happened to me before I think.
