The most simple swaps can cut hundreds of calories and excess fat from your recipes. Take some tips from me, and next time you're in the supermarket preparing for the week, consider purchasing these healthy options. Your body will thank you!

1) Skip the sour cream, SWAP Greek Yogurt

Onion dip made with sour cream (1/2 cup) = 227 calories, 20g fat
vs.
Onion dip made with Greek yogurt (1/2 cup) = 75 calories, 0g fat

Greek Yogurt, like Fage, Chobani or Oikos, contains about half the calories and fat and three times the protein than sour cream, making it a much healthier choice. Use Greek yogurt as a creamy base for onion dip or whip into a potato salad for that same bold and creamy flavor without the added calories and fat.

2) Skip the ground beef, SWAP lean ground turkey

Chili made with ground beef (1 cup) = 300 calories, 18g fat
vs.
Chili made with lean ground turkey (1 cup) = 200 calories, 4g fat

Choose ground turkey over ground beef. Not only will you save on half the calories and fat, but lean ground turkey won't cook down as much as regular ground beef, allowing you to get more bang for your buck. Instead of making a typical beef burger, make a turkey burger or stir up a bowl of hearty chili with lean ground turkey. Same hearty taste with half the fat!

3) Skip the cornflakes, SWAP oatmeal

1 bowl of cornflakes = 100 calories, 1g fiber
vs.
1 bowl of oatmeal = 150 calories, 4g fiber

Although you may love the cartoons on your cereal boxes, opt for a more nutritious and versatile oatmeal. Not only will you get cholesterol -- lowering fiber, some protein, vitamins and minerals -- but it comes in many different forms and varieties. Start your morning off by enjoying a filling bowl of oats. If you're on the run, stash a packet of instant oatmeal in your car or leave it in your desk drawer for a satisfying breakfast or snack. Rolled oats is also a healthy alternative to cornflake crumbs in meatloaf and meatballs. And probably one of the best perks of oats -- they make a delicious and nutritious crumble on top of any dessert!

4) Skip the iceberg, SWAP spinach

Salad with iceberg lettuce = 1g fiber, 19 mg calcium, 155 mg potassium
vs.
Salad with spinach leaves = 2g fiber, 59 mg calcium, 339 mg potassium

Swapping spinach for iceberg is an easy way to increase your intake of folate and other essential vitamins and nutrients, enabling you to reduce many risk factors for cardiovascular disease. Unlike iceberg lettuce, spinach doesn't only have to be the base of a salad. Toss spinach into some scrambled egg whites, roll it up into chicken breast or sauté it with garlic for a delicious side dish to any meal.

5) Skip the bacon, SWAP Canadian bacon

2 whole eggs with 2 slices bacon = 237 calories, 15g fat
vs.
4 egg whites with 2 slices Canadian bacon = 142 calories, 3g fat

Bacon can be a delicious morning treat, but as a lean alternative, choose Canadian bacon. It still has that crispy crunch and serves as a satisfying breakfast meat. With Canadian bacon, you can eat an extra strip or two for breakfast or chop it up into your Cobb salad to save calories and saturated fat.
