The Protein Calculator on Calcify can help you estimate your daily protein requirement based on your weight and exercise habit (or lack of it). Protein helps with muscle recovery & strength, and makes you feel full — helpful for both the lifter and just someone looking for a good nutritional balance. Instead of a one-size-fits-all protein number, it gives you a number based on you and your lifestyle.

As an example, if you weigh 70kg, and train 4 times per week, the Protein Calculator will provide an estimated requirement for you to effectively recover after training as well as maintain your lean muscle mass. This helps with meal planning, as you can gauge how much protein you should be consuming for each meal vs the total daily target. The Protein Calculator will also support your nutrition if your goal is muscle gain, weight loss, or you are simply recovering from activity, once you have calculated your protein needs, also check out more health calculators on Calcify.
