How to lose weight, get in shape, and run your best ever?

Daily Eats
BREAKFAST
Rotate three meals, says Pamela Nisevich Bede, M.S., R.D., sports nutrition expert for the Runner's World Challenge. Ideas: "adult" cereal (high on fiber, grains; low on sugar), oatmeal, Greek yogurt, or eggs. Always include fruit.
LUNCH
Rotate three to five meals. Ideas: salads (go easy on high-calorie toppings), sandwiches on whole grain (hold the mayo), eggs (if you didn't have them at breakfast), and broth-based soups. Always include fruit or a side of vegetables.
DINNER
Rotate five healthy meals like chicken, fish, and whole grains. Always include vegetables. "Keep your meals interesting by changing the vegetable and fruit sides and mixing up the preparation of the entree," Nisevich Bede says.
Go Off the Sauce
Beware of the hidden calories in sauces. Use tomato sauce instead of alfredo on pasta; substitute hummus or mustard for mayo on a sandwich; and make your own salad dressing: Add a little ranch seasoning to plain Greek yogurt, or a dash of olive oil and balsamic vinegar.
Take It Easy on Nut Butter
Runners love peanut and almond butters, and for good reason: They offer protein, healthy fats, and fiber in a convenient package. But a serving size is two level tablespoons. "People often end up eating three tablespoons," says Dimmick. "That's an awful lot of calories."
Make Fiber Your Friend
"Multiple studies have shown that fiber is correlated to weight loss as well as weight maintenance," says Jennifer Vimbor, M.S., R.D., founder of Nutrition Counseling Services in Chicago. Fiber passes through your system undigested, so your body has to work harder and longer to move it out, which helps rev your metabolism and give you a feeling of fullness. Aim to eat at least 25 grams of fiber a day: beans, whole grains, fruits and vegetables. (But to keep your GI tract quiet during your run, don't eat fiber two hours before you head out.)
