@harley_pasternak: There is no reason why you shouldn't indulge on vacation, but it's important to set yourself up for success the best you can. I always start the day filling up my plate with 1/2 or 2/3 of fruit and the other half with protein. That way I’m filled up and start the day feeling good. If you still want that donut or waffle after, then have it. It’s all about balance.
