Now that New Year's has arrived, many people will want to stick to their resolutions, such as losing weight or eating healthy.

But while some fast-food items are healthy, it's very easy to go wrong with fast food and have a few meals undermine your resolutions.

We looked at nutritional data from restaurant chains to find the worst of the worst. Over time, some nutritional data may change slightly — but these items are still high in calories.

Find out which items have the most calories, fat, saturated fat, sodium, and cholesterol.

You'll want to steer clear of them if you're watching your waistline.

Here are the offenders, in order of least to most calories.

Starbucks' Venti Egg Nog Latte

Calories: 630
Fat: 28 g
SaturatedFat: 17 g
Sodium: 320 mg
Cholesterol: 195 mg

Starbucks' holiday beverages are delicious, but the combination of egg nog and whole milk adds up. Opting for low-fat or skim milk will help you save a few calories.

Kentucky Fried Chicken's Pot Pie

Calories: 790
Fat: 45 g
Saturated Fat: 37 g
Sodium: 1,970 mg
Cholesterol: 75 mg

Chicken pot pie may be comfort food, but a meal that serves one shouldn't come this close to 800 calories or have this many grams of fat.

Chick-Fil-A's Sausage Breakfast Platter

Calories: 810
Fat: 54 g
Saturated Fat: 20 g
Sodium: 1,850 mg
Cholesterol: 385 mg

While this breakfast platter may not veer as closely to 1,000 calories as some other breakfast platters, it is still way too many calories. This meal contains roughly the recommended amount of daily fat intake, and it's just breakfast! Fortunately, there are less-caloric options on Chick-Fil-A's menu.
