Tired of having stare-downs with those boxes of Krispy Kremes, trays of brownies, and platters of cookies some well-intentioned but nutritionally clueless co-worker brings into the office? Be prepared for these and other nutritional setbacks at your office by stocking up on a few key items that will have your desk a veritable nutritional emergency kit.

Water: Bottles and bottles of water. Small bottles, big bottles, plastic bottles, glass bottles, whatever it takes. Having enough water within your reach everyday will keep you well hydrated as well as keeping your stomach filled when you’d otherwise fall prey to the lingering office munchies.

Fruit: Each week, bring a bag of fresh fruit to the office and store it in your desk. And don’t just stick with the common fare of apples and oranges. Berries, mangos, kiwi will keep for several days, more if you have access to an office refrigerator, and provide variety to whet your appetite for something other than those fudge brownies.

Protein bars: You can also use these as part of one of your daily meals. Be careful and read the labels. Many "nutritional bars" are nothing more than candy bars in deceptive packaging. Stay away from the ones with high sugar and fat content.

Vegetables: Bring a couple of small ziplocked bags of baby carrots, celery or your other favorite veggies that will keep.

Low-fat cottage cheese/low sugar yogurt: Small containers of these on hand will provide nutritional meal options.

Ricecakes: A bag of low-sodium ricecakes tucked away can satisfy a need to

Toothbrush/Mouthwash: I learned this trick from a friend who was a competitive bodybuilder. During pre-contest dieting, he would attempt to deflect the temptation to eat blacklisted foods within his reach by brushing his teeth. He said the last thing he wanted to do after brushing with minty toothpaste was chew a gooey piece of fudge or candy. Not bad for keeping your breath fresh, either.

Utensils: Make sure you have a serving or two of utensils at your desk, along with something to cut your food if needed.

Thermal-Lunchbags: Perfect for storing food when a refrigerator is not available. Available in many sizes.

The first step to staying on track with your eating, particularly at work, is planning. You don’t have the power to control what your co-workers bring into the office, but you can help ward off temptation by stocking up on a few items of your own. Remember, the point is to not make your own desk resemble a supermarket aisle, but to have enough options on hand in order to substitute for the really bad stuff should the need arise.
