How many calories do 11 grams of protein provide?

Protein contains 4 calories per gram. To determine how many calories are in 11 grams of protein, you would multiply the number of grams by the number of calories per gram:

11 grams of protein x 4 calories/gram = 44 calories.

Therefore, the correct calculation confirms that 11 grams of protein provides 44 calories. This is fundamental in understanding macronutrient contributions to overall caloric intake, which is important in nutrition, diet planning, and kinesiology. The other options do not reflect this correct conversion and thus do not represent the accurate caloric content from 11 grams of protein.
