I had vacation for two weeks in June and I ate in restaurants for every meal.I did not gain an ounce.Breakfast was easy and the other two meals i had salad and chicken or shrimp or lobster or steak.Make sure you have a can of nuts for when you are hungry you can grab a few or a hunk of cheese.Pack lots of water and i ate strawberries and cream every day also.I just got of another week vacation of eating out every day and again no weight gain.I feel like I really have a handle on this plan now and it is a life plan for me.Don't forget to pack your vitamins.Have a great vacation.
