How many calories are in an entire Jack’s frozen pizza?

Jack’s frozen pizzas are a popular convenience food option for many busy families. With their wide variety of tasty flavors, ability to quickly bake in the oven, and relatively low cost, Jack’s pizzas provide an easy dinner solution when time is tight. However, with America facing high levels of obesity and related health issues, more consumers are becoming concerned about the nutritional value of the foods they eat, including frozen pizzas. When you are feeding a household of hungry mouths, it can be challenging to find freezer foods that align with health goals. So how many calories are actually in one of those convenient Jack’s frozen pizzas? Let’s take a detailed look at the calorie counts.

The specific calorie content will vary somewhat based on the exact toppings and crust, but most of these frozen pizzas contain between 290-370 calories per serving. With most Jack’s pizzas containing around 4 servings per pizza, that equates to approximately 1160-1480 calories for the entire pizza.

Here is a rundown of the calorie counts for some of the most popular Jack’s frozen pizza flavors:

Cheese Pizza

– Calories per serving: 370
– Total calories for whole pizza: 1480

Pepperoni Pizza

As you can see, the entire Jack’s frozen pizza can range from 1160-1480 calories depending on the variety. Most of them land in the 1400-calorie range for the complete pizza.

Daily Calorie Needs

To determine if eating a full Jack’s pizza fits into your daily calorie allotment, you need to know how many calories you should be consuming each day. The number of calories needed varies significantly based on age, gender, activity level, and weight goals.

Here are some general guidelines for daily caloric requirements:

– Women
– Sedentary (little/no exercise): 2000-2200 calories
– Moderately Active: 2000-2400 calories
– Active (daily exercise): 2400-2800 calories

– Men
– Sedentary: 2400-2800 calories
– Moderately Active: 2600-3000 calories
– Active: 3000-3600 calories

So for example, a moderately active woman would need about 2200 calories per day. A sedentary man would need around 2600 calories. These numbers can help determine if a 1400 calorie frozen pizza fits into your diet or if it’s too much.

Those trying to lose weight would need to consume fewer calories, while more active individuals may be able to incorporate higher calorie foods. Teenagers and children have lower caloric needs as well.

Pizza Nutrients

While calories give a general indication of energy content, looking at the full nutrient profile of Jack’s pizzas provides more valuable information.

Some key nutrients found in a frozen cheese pizza include:

– Protein: 25g
– Carbohydrates: 45g
– Dietary Fiber: 2g
– Total Fat: 15g
– Saturated Fat: 6g
– Sodium: 790mg

Along with calories, frozen pizzas can deliver a significant amount of fat, sodium, and carbs. However, they also provide protein for muscle health and small amounts of vitamins and minerals from the tomato sauce and cheese.

Overall, the nutritional value depends on your specific diet plan. Those limiting carbs and sodium may want to consume just 1-2 slices of pizza instead of the whole thing. But for some, a full Jack’s pizza can fit into their daily goals, especially if they are young, active individuals with higher calorie needs.

Strategies for Healthy Pizza Eating

While frozen pizzas are convenient, their high calorie counts may not align with your wellness objectives. Here are some tips for enjoying pizza in a healthier way:

– **Stick to 1-2 slices.** Instead of consuming the entire pizza in one sitting, portion out just a serving or two. This limits calorie intake while still letting you enjoy the delicious flavors.

– **Add veggie toppings.** Opt for healthier pizza toppings like mushrooms, onions, peppers, spinach, or pineapple to increase nutrients.

– **Try alternative crusts.** Cauliflower, chickpea, or thin whole wheat crusts provide fewer carbs and calories than traditional white flour dough.

– **Limit unhealthy toppings.** Go easy on high-calorie meats like pepperoni, sausage, and bacon which can quickly drive up fat and sodium content.

– **Use healthy cooking methods.** Bake pizza in the oven instead of ordering greasy delivery. Avoid thick, buttery crusts.

– **Balance with nutritious foods.** Enjoy pizza alongside a salad, veggies, or other wholesome options to help create an overall healthy eating pattern.

– **Watch portion sizes.** Be mindful of serving sizes, as it’s easy to overeat high-calorie foods. Practicing mindful eating helps prevent overconsumption.

Making small tweaks can transform pizza from an occasional treat into a mainstay of a nourishing diet.

Health Risks of Large Pizza Servings

While the occasional indulgent pizza meal likely won’t cause harm, regularly consuming entire pizzas in one sitting can lead to problems over time due to excess calories, saturated fat, carbohydrates, and sodium. Potential health risks of a high frozen pizza intake include:

– Weight gain and obesity
– Increased heart disease and stroke risk
– Higher blood pressure and cholesterol
– Greater risk of type 2 diabetes
– Nutritional deficiencies
– Digestive issues like bloating and reflux
– Decreased energy levels

To keep health risks low, practice moderation and stick to reasonable portion sizes instead of frequently polishing off whole pizzas alone. Enjoy Jack’s frozen pizza as an occasional treat, not a dietary staple.

Typical Jack’s Pizza Serving Sizes

Jack’s pizzas are designed to contain roughly 4 servings per pizza. But what does one serving actually look like?

Here are typical serving sizes for a Jack’s frozen pizza divided into quarters:

– 1/4 of a 12″ pizza = 150-185 calories
– 1/4 of a 14″ pizza = 220-275 calories
– 1/4 of a 16” pizza = 250-315 calories

Consuming just a single quarter of the pizza provides a reasonable serving with adequate calories, carbs, and nutrients for most adults. It also helps limit fat and sodium intake compared to much larger portions.

Of course, serving sizes can be adjusted based on your unique calorie needs and diet. Active teenagers or men may be able to consume more, while older adults or women trying to lose weight would want smaller servings.

Making Your Own Healthy Pizza

For complete control over nutrition and ingredients, consider making homemade pizza instead of relying on frozen varieties. Here is a simple and healthy homemade pizza recipe:


Whole Wheat Pizza Dough:
– 1 package active dry yeast
– 1 cup warm water
– 1 tablespoon honey
– 2 cups whole wheat flour
– 1⁄4 cup olive oil
– 1 teaspoon salt

Pizza Sauce:
– 1 15oz can unsalted tomato sauce
– 1 tablespoon olive oil
– 2 cloves garlic, minced
– 1 teaspoon oregano
– 1 teaspoon basil

– Low-fat mozzarella cheese
– Sliced mushrooms
– Diced bell peppers
– Chopped spinach or kale
– Sliced onions
– Sliced chicken breast


1. Activate the yeast by mixing it with warm water and honey. Let stand for 5-10 minutes.

2. Combine activated yeast with whole wheat flour, olive oil, and salt. Knead dough until smooth.

3. Place dough in oiled bowl, cover, and let rise 1 hour.

4. While dough rises, prepare sauce by sautéing garlic in olive oil, then mixing in tomato sauce and herbs.

5. Once dough has risen, spread onto a pan or pizza stone. Top with sauce, cheese, and desired toppings.

6. Bake at 450°F for 12-15 minutes until crust is crisp.

7. Let cool slightly before slicing and serving. Enjoy!

With wholesome ingredients and reasonable portion sizes, homemade pizza can be a nutritious meal option. Get creative with your own healthy toppings too!

Frozen vs. Homemade Pizza

How does homemade pizza compare to frozen varieties when it comes to nutrition? Here is a general calorie and nutrient comparison:

Frozen Cheese Pizza

– Calories: 300 per serving, 1200 per pizza
– Fat: 13g per serving
– Carbs: 36g per serving
– Protein: 18g per serving
– Sodium: 660mg per serving

Homemade Veggie Pizza

– Calories: 250 per serving, 1000 per pizza
– Fat: 5g per serving
– Carbs: 35g per serving
– Protein: 12g per serving
– Sodium: 400mg per serving

As you can see, homemade pizza is a little lower in calories and unhealthy fat and sodium when made with wholesome ingredients. However, both options can be enjoyed in moderation. Just be mindful of portion sizes, especially when eating store-bought frozen pizza which tends to be higher in calories.

Low-Calorie Jack’s Pizza Options

If you want to enjoy the convenience of Jack’s pizza but limit calories, here are some tips:

– Choose a thinner crust option to save calories
– Get a smaller 10-12 inch pizza instead of a 16 inch
– Load up on veggie toppings instead of higher-calorie meats
– Opt for lighter sauces like barbecue instead of creamy alfredo
– Stick to just 1-2 slices instead of the whole pizza
– Add a side salad for nutrients and fill up on veggies
– Split the pizza with a friend or family member

With smart modifications and reasonable portions, you can still satisfy that pizza craving without going overboard on calories.

High-Calorie Pizza Pitfalls

It’s easy to accidentally consume more calories than you realize when eating pizza. Watch out for these common pitfalls that can cause calorie counts to skyrocket:

– Extra meat toppings like pepperoni, sausage, bacon
– Thick, doughy, buttery crusts
– Large pizza sizes (16-18 inches)
– Creamy, fatty sauces like alfredo
– Fried or greasy pizzas from restaurants
– Eating too many slices – entire pizzas
– Pairing with sugary drinks like soda or lemonade
– All-you-can-eat pizza buffets
– Late night post-drinking pizza runs

Pizza can fit into healthy eating patterns, but it’s important be mindful of servings and ingredients to keep calories reasonable.

Estimating Leftover Pizza Calories

Leftover pizza is common when you can’t finish the entire thing in one sitting. Here’s how to estimate calories if you save pizza for later:

– Weigh your leftover pizza slices or portions on a food scale
– Check the nutrition info on the original frozen pizza package to find the calories per gram
– Use the food scale weight and the calories/gram to calculate calories in your leftovers

For example:
– You have 258g of leftover pizza
– The pizza has 280 calories per 100g
– So 258g of leftovers x (280 calories/100g) = 723 calories in your leftovers

If you don’t have a food scale, visually divide leftovers into serving sizes based on a quarter of the pizza or the original nutrition info. Be aware that eating old leftover pizza late at night can lead to overconsumption of calories.

Burning Off a Jack’s Pizza

Eating an entire 1,400 calorie pizza may necessitate some extra activity to burn those calories off. Here’s how long it would take to burn off a full Jack’s pizza with various exercises (for a 160 lb person):

Exercise Calories burned per hour Time to burn 1400 calories
Walking (3 mph) 200 7 hours
Jogging (5 mph) 500 2 hour 48 minutes
Hiking 370 3 hours 48 minutes
Biking (10 mph) 400 3 hours 30 minutes
Swimming 500 2 hours 48 minutes
Aerobic Classes 600 2 hours 20 minutes

As you can see, an extended walk or jog can help expend the extra calories from pizza. But for less active individuals, that 1,400 calories may end up directly stored as body fat. This highlights the importance of managing portion sizes when eating calorie-dense foods.


How many calories in a full Jack’s pizza? Most varieties contain around 290-370 calories per serving, or approximately 1,160-1,480 calories for the entire pizza. While the occasional indulgence is fine, regular consumption can lead to weight gain and other health issues. To enjoy pizza as part of a healthy diet, practice portion control, add veggie toppings, and balance with nutrient-dense foods. With some simple strategies, you can still satisfy your pizza cravings without derailing your nutrition goals.
