I am always watching my weight and always on vacation
I have a few things that help me and may help you. I do not think of myself as ever on a diet, I just eat healthy. So first get the word "diet" out of your brain
For breakfast some smart choices: Eggs benedict (my way) no butter on english muffin, no sauce. It is healthy because it is 1 english muffin, 2 poached eggs and canadian bacon total cals = 350, round it out wiht fresh fruit and you have a great breakfast. Egg white omlette with veggies and 1 slice dry toast or oatmeal and fruit. A kids portion of Mickey waffles and fruit are also great choices. Keep away from regular bacon and sausage...loaded with cals, fat and salt. Also drink water or unsweetened iced tea with lemon instead of juice with your breakfast.
Grab a snack of fruit, apple small orange or a melon cup and drink lots of water. Don't wait to have a piece of fruit have it 2-3 hours after breakfast. Apples are espically good, they make you feel full.
Lunch is not tricky at all. I always get a salad no cheeses or fattening stuff, with dressing on the side, any kind of dressing and grilled chicken, shrimp or fish. Dip your fork into the dressing first then into the salad. You will not be using a lot of dressing but you will have all the flavor. Shrimp cocktail and a veggie salad is also good.
Between lunch and dinner I usually have another snack...fruit or a dole whip *no vanilla* there are actually lots of fun stuff you can eat...cotton candy is fat free and low in calories, dark chocolate is better for you than milk chocolate.
Dinner has no rules....I have drinks, always a big salad, and anything I want to eat lean protein - fish, chicken, steak...no fatty sauces. Dessert is always shared with DH .
If you splurge and have a cheeseburger or ice cream- enjoy - not just while on vacation but in everyday life.
For the most part avoid anything that is too salty, fried, sauteed, smothered, creamed etc...
Drink lots of fluids and eat something every 3 hours (fruit, cereal bar etc) before you get hungry and allow yourself 1 splurge meal per day since you are walking lots of miles. 2 healthy meals and 1 splurge meal will keep you feeling good and you will lose weight without even knowing it.
I used to work for Jenny Craig, so I was trained on meal planning.
