Basics How to Calculate How Much Protein You Need By Laura Dolson Updated September 04, 2018 Pin Flip Email Print LauriPatterson / Getty Images More in Basics Hot Topics Food Safety It's important that we eat enough protein each day to cover our body's needs. There are two ways of calculating a person's protein requirements. The standard minimum amount of daily protein recommended is .37 gram per pound of body weight (or .8 grams per kilogram of body weight). Although, your own personal needs may vary based on multiple factors including your age, activity level, and weight loss goals, let's start off easy. This first method of calculating your protein needs is simply based on your weight. The chart below shows the minimum amount of protein you need based on the .37 gram per pound that the United States Institute of Medicine recommends. Athletes and heavy exercisers should probably double this amount, so that's included in the chart. Is There a Maximum Amount of Protein? Maximums are not included in the chart because the recommended maximums are usually calculated by the percentage of calories consumed with the upper limit being 35%. This would be about 170 grams for a person taking in 2000 calories per day if they are not losing weight (people on weight loss diets should not go by percentage). In truth, people rarely have to worry about this maximum as it has been noted repeatedly that people will naturally stop before this point. The body just does not "want" very high levels of protein in the diet, and people start feeling sick (or at least sick of protein) before getting too much. There are two charts here—if you weigh yourself in kilograms, scroll down to the next chart. Weight in lbs. Minimum Protein Athletes Minimum 100 37 grams 74 grams 110 40 grams 80 grams 120 44 grams 88 grams 130 47 grams 94 grams 140 51 grams 102 grams 150 55 grams 110 grams 160 58 grams 116 grams 170 62 grams 124 grams 180 65 grams 130 grams 190 69 grams 138 grams 200 72 grams 144 grams 210 76 grams 152 grams 220 80 grams 160 grams 230 84 grams 168 grams 240 87 grams 174 grams 250 91 grams 182 grams 260 95 grams 190 grams 270 98 grams 196 grams 280 102 grams 204 grams 290 105 grams 210 grams 300 109 grams 218 grams Minimum Daily Protein Requirements Weight in kg.

Some experts feel that this is a more accurate technique since our lean body mass (that is, the part of our bodies that isn't fat) requires much more protein for maintenance than fatty tissue does and how active we are also figures into it.
