SHOOT: Some great advice, and it's not rocket-science.
Just add water. In addition to being your source for scintillating office gossip and banter about last night's episode of Mad Men, the watercooler can help you lose weight. Keeping H20 at the ready will give you something to put in your mouth besides sweets from your neighbor's candy bowl.
Set an exercise meeting. A midday workout keeps your energy up and the pounds down. Protect your exercise time by putting sweat sessions in your calendar just as you would meetings with your most important client.
Bring your own snack. Slip a healthy bite into your tote as you leave the house in morning, and you won't be taunted by that Butterfinger in the vending machine when the afternoon munchies strike. To stay satiated—and sharp—until supper, aim for a bite that contains about 200 calories, some fiber and a smidge of protein, too.
Team-build. Recruit a few like-minded coworkers to get fit with you. You'll foster friendships at the office (always a good thing) while knocking off pounds.
