Healthy Low-Calorie Snacks for Weight Loss

Understanding Calories and Protein

When it comes to nutrition and diet, calories and protein are two important concepts to understand. But how exactly do they relate to one another? Specifically, how many calories are in 1 gram of protein?

Read on to learn more about the calorie and protein relationship, the calorie count of different protein foods, and how to incorporate the right balance of each into a healthy diet.

How Many Calories in 1 Gram of Protein?

Protein contains approximately 4 calories per gram.

To be exact, 1 gram of protein has 4.27 calories. Protein is one of the three main macronutrients that provide energy, also known as calories, to the body. The other two macronutrients are carbohydrates and fats.

Here is how the calorie count breaks down for each gram of the three macronutrients:

• Protein: 4 calories per 1 gram
• Carbohydrates: 4 calories per 1 gram
• Fat: 9 calories per 1 gram

As you can see, fat provides over twice as many calories as protein and carbs per gram. That is why high-fat foods tend to be very high in calories, while foods rich in protein and carbs are typically lower in calories by volume.

Why the Body Needs Protein

Protein is an essential part of every cell, tissue, and organ in the human body. It is vital for building lean muscle mass and strength.

Some key functions of protein include:

• Building and repairing muscle tissue
• Supporting bone health
• Facilitating proper immune function
• Creating important enzymes and hormones
• Maintaining healthy skin, hair, and nails

Protein is especially crucial for athletes, bodybuilders, and anyone looking to build or maintain muscle mass. Resistance training causes small tears in muscle fibers. Consuming adequate protein helps repair these tears and allows the muscles to grow back bigger and stronger.

Recommended Protein Intake

How much protein you should eat each day depends on many factors including age, gender, activity level, and health status. The U.S. FDA provides these daily recommended protein intakes:

• Adult men: 56 grams
• Adult women: 46 grams
• Pregnant or breastfeeding women: 71+ grams
• Child ages 4-13: 19-34 grams
• Teens: 34-52 grams

Athletes, bodybuilders, and highly active individuals may need 0.5-0.8 grams of protein per pound of body weight. For a 150 pound person, that equals 75-120 grams of protein daily when strength training.

Counting Protein Calories

To determine the calories from protein in a particular food, you'll need to check the nutrition label or nutrient data. Let's take a look at some examples.

Chicken Breast

A 3 ounce boneless, skinless chicken breast contains approximately:

• Calories: 110
• Protein: 25 grams
• Fat: 1 gram
• Carbs: 0 grams

With 25 grams of protein, and knowing there are 4 calories per gram of protein, the protein in 3 ounces of chicken breast contains about 100 calories.

25 grams protein x 4 calories/gram protein = 100 calories from protein

The remaining 10 calories come from a small amount of fat.

Greek Yogurt

One 6 ounce container of nonfat plain Greek yogurt contains:

• Calories: 100
• Protein: 18 grams
• Fat: 0 grams
• Carbs: 9 grams

With 18 grams of protein, a 6 ounce serving provides about 72 calories from protein:

18 grams protein x 4 calories/gram protein = 72 calories from protein

The other 28 calories come from the 9 grams of carbohydrates.

Tofu

A 12 cup serving of firm tofu contains:

• Calories: 94
• Protein: 10 grams
• Fat: 5 grams
• Carbs: 2 grams

With 10 grams of protein, 12 cup of tofu has around 40 calories from protein:

10 grams protein x 4 calories/gram protein = 40 calories from protein

The remaining 54 calories (9 from fat + 2 from carbs) come from non-protein sources.

High Protein, Low Calorie Foods

When reducing calories for weight loss, it's important to still consume adequate amounts of protein. Here are some of the top high protein, low calorie food options:

Egg Whites

Egg whites provide the protein of whole eggs without the fat and cholesterol. A large egg white has about 17 calories and 4 grams of filling protein.</
