It is recommended that out of the total energy intake, 15 to 25% energy should be from protein sources.

Out of the three macronutrients, the fats, the carbohydrates and the proteins, we talk very little about the importance of protein and its daily requirement for the body. Protein is an important building block of a healthy diet. It is present in every cell in the body and performs the important function of building and maintaining muscles and bones. It also keeps the cells in a good working condition. If there is a lack of protein in the body, this may invite trouble in the sense that breakdown of the existing muscles will happen at a faster rate as compared to the formation of the new ones, resulting into malfunctioning of the body organs. However, most Americans, unknowingly, meet or even exceed the recommended amount of protein per day. When it comes to ideal protein requirement of the body, it varies from individual to individual. A lot of it has to do with the kind of lifestyle a person is leading i.e. active or sedentary. It also depends on the kind of fitness goals people have like they want to lose weight, build muscles or gain weight, etc.

Although the daily required amount of protein depends on several factors like age, gender, weight, activity level, etc., there is a standardized method used by the nutritionists to calculate the minimum daily protein requirement. The body weight in kilograms when multiplied by 0.8 (it is the amount of protein required per kilogram) or the weight in pounds multiplied by 0.37 will give the amount of protein (in grams) to be consumed daily. To take an example, if the weight of a person is 60 kg, then his recommended protein intake per day would be 60 kg
