I've lost a lot of weight in the past and usually vacation to WDW for 3 weeks so I can't afford to eat whatever I want during tat time. When I have on previous trips, even with the extra walking, I'd gain around 1stone. So I eat breakfast at the bills, usually a bagel or breakfast biscuits and maybe fruit. Mid morning snack was usually almonds or a snack bar For lunch I take a small cool bag with a frozen drink I and a salad along with a 100 calorie snack and some strawberries. Another small snack in the afternoon Then a tea out where ever we wanted. It was usually Cheesecake Factory, Longhorns or somewhere similar. I tended to order from the lower calorie menu and wouldn't always have dessert. Sometimes we'd go for a cooked chicken from
Walmart or Pizza. As I'm from England I loved eating American in too so sometimes we'd ave breakfast out and tea in. I'd also have my must have snack list as treats!! I know the way I vacation might be too strict for most but I only eat food I love!! I don't deprive myself and I enjoy my meals without feeling guilty after! Good luck!
