How to Use a Protein Calculator to Determine Your Daily Protein Needs
Determining Your Daily Protein Needs
Your daily protein needs depend on various factors, including your goal body weight, activity level, current body fat levels, and fitness goals. Understanding these factors and adjusting your protein intake accordingly can help you achieve optimal health and fitness.
Leading your diet plan with protein is a good way to center your health as it allows you to figure out calorie intake, fiber needs, and everything in-between along the way. The Wellness Way has built a
protein calculator to help you understand and achieve health and fitness goals.
There are many considerations when arriving at a number. The
RDA has arrived at many numbers over the last half decade, however those numbers tend to fluctuate and are based on preventing malnutrition as opposed to actual optimal performance.
How To USE The protein Calculator
To calculate your daily protein needs, consider your weight, activity level, and fitness goals. Here’s a step-by-step guide to help you determine the optimal amount of protein for you:
- Enter Your Weight: Choose your weight in Kilograms or Pounds. This is a required part of the calculation process.
- Determine Your Activity Level: Assess whether your activity level is low, medium, or high based on the descriptions above.
- Identify Your Fitness Goals: Decide whether you want to lose weight, maintain your current fitness level, tone up, or build muscle.
- Calculate Protein Intake: Based on your activity level and fitness goals, determine the appropriate protein intake range. For a sedentary individual, a protein intake of 1.2–1.8 g/kg can maintain weight and body composition. However, for increased physical activity levels, aim for higher protein intake.
So let's start an example of how to calculate your protein intake based off an example of someone weight 180 lbs.
WEIGHT
Here is what the basic calculation looks like for the optimal protein intake for someone that weighs 180 lbs.
| Weight (lbs) | Weight (kg) | Grams per Day (Range) |
|---|---|---|
| 180 | 81.65 | 102 - 147 |
Activity Level
There are indeed many different levels of activity that you could possibly be at, and not everyone should be consuming as much protein as
"The Rock" does on a daily basis. This protein calculator categorizes activity levels into three main types to simplify the process:
Low Activity Level
A person with a low activity level spends most of their day sitting with minimal activity. They engage in little to no structured exercise each week. The average individual balances their time between sitting and standing and participates in light exercises, such as 30 to 45 minute brisk walks several times each and every week.
Medium Activity Level
In contrast, someone with a medium activity level is often on their feet throughout the week. They engage in light exercise at least four times a week or intense exercise at least twice a week.
High Activity Level
An individual with a high activity level, such as an athlete, engages in intense exercise three to four times a week, focusing on vigorous workouts that significantly elevate the heart rate.
Your activity level plays a crucial role in determining your protein needs. The more active you are, the higher your protein requirements to support muscle repair, recovery, and growth.
Let's go back to our example of protein intake for someone that is 180 lbs. Here's what that would look like based on different activity levels:
| Activity Level | Grams per Day (Range) |
|---|---|
| Lightly Active | 122 - 171 |
| Moderately Active | 148 - 196 |
| Very Active | 171 - 220 |
Fitness Goals
Fitness goals are specific outcomes you aim to achieve through diet, particularly optimal protein intake, and exercise.
Lose Weight
If your goal is to lose weight, you aim to shed unnecessary fat without prioritizing muscle gain. For this reason, protein recommendations tend to be more static. To maintain your current fitness level without making significant changes to your physical appearance or athletic capabilities, your diet is usually "eucaloric" or "equicaloric," meaning you consume about as many calories as you burn.
Tone Up
Toning up involves losing fat and gaining muscle mass simultaneously, though not to the extent of a bodybuilder. The objective is to become leaner and fitter, typically without focusing heavily on weightlifting.
Build Muscle
Building muscle involves increasing muscle size and usually body weight. The goal isn’t to lose weight, but it’s important to note that the more muscle you have, the more fat you will generally lose.
Protein is essential for achieving these fitness goals as it provides the amino acids necessary for tissue repair, recovery, and muscle growth. It also helps preserve lean muscle mass and body composition while promoting satiety. By aligning your protein intake with your specific fitness goals, you can optimize your diet to support your desired physical outcomes.
For example, if you weigh 70 kg (154 lbs), and your goal is to tone up with a medium activity level, aim for a protein intake of 1.6–2.2 g/kg per day. This translates to 112–154 grams of protein daily.
Here's what the protein calculator would produce for someone that is 180 lbs when you factor in your
goals:
| Goal | Lightly Active (Grams per Day) | Moderately Active (Grams per Day) | Very Active (Grams per Day) |
|---|---|---|---|
| Maintain | 122 - 171 | 148 - 196 | 171 - 220 |
| Toning | 131 - 196 | 164 - 220 | 196 - 264 |
| Muscle Growth | 139 - 203 | 171 - 220 | 203 - 270 |
| Weight Loss | 131 - 164 | 139 - 180 | 148 - 180 |
