Hi, Maureen ! Gosh, it must be wonderful to be able to stay in Spain for two months ! Take me with you !! :)
What to do ? When I'm in Europe, I eat like a local. I just came back from a week in Amsterdam. I can't tell you how much cheese and butter I ate. But you know what ? I didn't gain weight. The Dutch people do not have the obesity problems that the US does. Why ? because they eat smaller portions and they get regular exercise. The Dutch ride bikes, lots of bike. They walk a lot too, just like many other Europeans.
What do the locals in Spain do for exercise ? Do they walk every where ? If so, try being like a local and walking to more and more places. Also, how often do they eat those yummy pastries ? If they don't eat them every day, neither should you. Eat them like they do as a once in a while treat. I'll bet they eat plenty of fresh fruit. I know when I was in Italy, I saw Italians constantly munching on a piece of fruit.
So, how about trying to eat more servings of their yummy local fruit ? That's another way to get back on track while you're away. Mostly, do try to be mindful of your portions. It's okay to indulge, but you don't want to over indulge too often.
I've been thinking Spain may be my next road trip. Thinking about doing the walk to Saintiago de Campostella.
