Do it yourself

These are great prepare-ahead healthy meals that will keep you feeling full and help you control your weight:

Make a dried-fruit-and-nut mix for emergency snacking. (Be wary of granola, since it typically has lots of sugar, says Stokes.) Pack small amounts in a little plastic bag - great for the car or office.
Cook a big pot of homemade vegetable soup, which can be frozen for several lunches or dinners.
Try smoothies - blend low-fat yogurt and fruit - for a grab-and-go meal.
Mix up big salads or a pasta primavera with lots of veggies and whole-wheat pasta. Prepare large quantities so you can have a moderate-sized helping for dinner and then have leftovers for lunch the next day.
