1)  "Just say no" to trigger foods - for me this means no sweets & breads. 

2)  Exercise (walk, jog, stairs) at least 150 minutes each week.  

3)  Track all food & activity on myfitnesspal.

4)  Add in natural activity at least two different ways each day:  park at farthest parking spot, stand up at my desk most of the day, take the stairs at work to my 4th floor office, walk to a bathroom on another floor at work, walk to mailbox, etc.

5)  Don't let one bad decision turn into one bad day or a bad week.  I love the idea of 4/5 mentality!
