There are 4 Calories in a gram of protein, 4 calories in a gram or carbohydrates and 9 calories in a gram of fat. Protein is the last source of energy the body uses (otherwise you would be losing muscle). Fat is obviously the hardest to burn because it is only used once the carbs are used up, and fat contains more than 2x the calories per gram.
The acceptable macronutrient distribution ranges (ADMR) state that protein should make up 10-35% of total calories. You can calculate this easily.
1) Each protein provides 4 calories per gram, so first take the grams of protein consumed and multiply by 4. This will give you the calories provided by the protein you consume.
2) Divide this number by total calories consumed in the day and you will have the percent of calories provided by protein.
If you look on "the box" on almost any food product, it will show a 2,000 calorie diet. This really isn't right. Below is a chart that you might find helpful from http://howmanycaloriesshouldieat.blogspot.com/
For a person who practices 30 minutes or less of moderate physical activity, the number of calories that they should eat
Children--------2-3 years old 1000 calories
Children--------4-8 years old 1200-1400 calories
Girls-------------9-13 years old 1600 calories
Boys------------9-13 years old 1800 calories
Girls------------14-18 years old 1800 calories
Boys-----------14-18 years old 2200 calories
Females-------19-30 years old 2000 calories
Males----------19-30 years old 2400 calories
Females-------31-50 years old 1800 calories
Males----------31-50 years old 2200 calories
Females-------51+ years old 1600 calories
Males----------51+ years old 2000 calories
For a person who practices 30 minutes to at least 60 minutes or more of moderate physical activity, the number of calories that they should eat:
Children--------2-3 years old 1000-1400 calories
Children--------4-8 years old 1400-1800 calories
Girls-------------9-13 years old 1600-2200 calories

Females-------31-50 years old 2000-2200 calories
Males----------31-50 years old 2400-3000 calories
Females-------50+ years old 1800-2200 calories
Males----------50+ years old 2200-2800 calories
But to answer your question, I need to say 2,000. There really is no "average" calorie count.
Sorry to not completely answer your question.
There are 4 calories in one gram of protein.
Every gram of protein has 4 calories. A teaspoon of pure protein has 4 grams or 16 calories.
Carbohydrates and proteins both have 4 kilocalories (the kind of calories that the government measures in food) per gram. By contrast, alcohol and fat both have 9 calories/gram.
4
Four
1 gram of protein = 4 calories.
1 gram of protein is equivalent to 4 calories.
4 calories in 1 gram of protein!
4 calories
4 calories
There are 4 calories per gram of protein.
1 gram of protein is the equivalent to 4 calories.
1 gram carbohydrate = 4 calories 5 gram carbohydrate = 20 calories
One gram of carbohydrates = 4 Calories One gram of Protein = 4 Calories One gram of Fat = 9 Calories
1 gram protein = 4 calories 4 gram protein = 4x4= 16 calories
There are 9 calories in a gram of fat.And there are 4 in 1 gram of protein and 1 gram of carbohydrate
Protein and Carbohydrates are both 4 calories per gram, and Fat is 9 calories per gram.
