diet
Hmmmm Everyone is having an emphasis on NOT eating or CUTTING back on foods. This sounds alright if it is cutting back on the carbs or fats BUT my suggestion for You to lose weight is to basically eat MORE nutritious meals MORE often! (this does not mean stuffing yourself!)
I used to work in the entertainment business and often shifts are odd and you can't always get a nutritious meal. There is always great pressure on looking "great" but keeping on the go! I imagine being a flight attendant is similar! ie. working at odd hours, eating a meal then crashing during the day with no exercise! and food is usually high in carbs or fat! (I know because I work in Qantas flight catering!)
I found that if you eat a small snack of fruit that is filling ie Apple/Banana & bottle of water (these things are handy carrying anywhere) every hour you wont feel so hungry and wont stuff yourself when it's time to eat a meal.
Try to stay away from Carbs altogether espeacially not within the 6 hours before you sleep (so no rice etc!) and if you do have to eat a larger meal have it before you know you are going to have time to burn it off...dont have it before u rest!
Regular exercise!!! VERY important...I suggest a simple cardio exercise. Get on the bike and SWEAT!!!! and dont laugh but I found Yoga great for toning, unwinding and keeping balanced. I strongly recommend Yoga for flight attendants!!!
Good luck everyone and happy new year!!
