Turn weight, activity, and goal into a daily protein target

Protein needs vary by body size, training load, and objective. This page uses a simple grams per kg approach, then applies a goal adjustment. You get a daily gram target plus charts, compare, copy, and a printable PDF layout.

How to use the Protein Intake Calculator

  1. 1

    Enter your weight

    Type your weight and choose kilograms or pounds.

  2. 2

    Select activity level

    Choose from sedentary to very active to set a starting grams per kg value.

  3. 3

    Select your goal

    Maintenance keeps the baseline. Muscle gain and fat loss apply a small adjustment within common ranges.

  4. 4

    Calculate and compare

    Press Calculate to see the daily grams target, charts, scenario compare, and a PDF export layout.

Detailed guide and references

What this tool does

The Protein Intake Calculator estimates daily protein needs from your weight, activity level, and fitness goal. It converts pounds to kilograms when needed, selects a grams per kg target, then multiplies by body weight to produce a daily grams value.

Baseline and ranges

A widely cited baseline for many sedentary adults is 0.8 grams per kilogram of body weight per day. Practical targets often go higher depending on training and objective.

  • Baseline: 0.8 g per kg
  • Common training range: roughly 1.2 to 2.0 g per kg
  • This page uses a simple max reference of 2.2 g per kg for chart comparison

Activity based needs

More activity can increase protein turnover and repair demand.

  • Sedentary: 0.8 g per kg
  • Light: 1.0 g per kg
  • Moderate: 1.2 g per kg
  • Active: 1.6 g per kg
  • Very active: 2.0 g per kg

Goal adjustments

Goals can shift targets slightly. This calculator keeps adjustments conservative and bounded:

  • Maintenance: uses the activity baseline
  • Muscle gain: ensures at least 1.6 g per kg, then adds a small bump up to 2.2 g per kg
  • Fat loss: ensures at least 1.2 g per kg, then adds a small bump up to 1.6 g per kg

Factors that can change your needs

Body size and composition

  • Heavier bodies generally require more total grams.
  • For athletes, lean mass can be a useful refinement, but this tool uses total weight for simplicity.

Training type

  • Strength training often uses higher targets than casual activity.
  • Endurance training can also raise needs depending on volume.

Age and health context

  • Older adults and medical conditions can change recommended intake.
  • If you have kidney disease or other conditions, use professional guidance.

Protein sources

Animal sources

  • Meat, poultry, fish: roughly 20 to 30 g per 100 g
  • Eggs: about 6 to 8 g per egg
  • Dairy: varies by product and serving size

Plant sources

  • Legumes: roughly 7 to 10 g per 100 g cooked, varies by type
  • Nuts and seeds: roughly 5 to 7 g per 30 g
  • Whole grains: modest amounts that add up over a day

Practical tips

  1. Use a consistent weight measurement, especially if comparing scenarios.
  2. Spread protein across meals to make targets easier to hit.
  3. Use the chart view to sanity check how aggressive the per kg target is.
  4. Use the PDF export for a clean shareable summary.

Results are estimates and may differ based on individual metabolism, diet quality, and medical context.

FAQs

Is 0.8 g per kg enough?

0.8 g per kg is a common baseline for many sedentary adults. Training volume and goals often use higher targets.

Should I use body weight or lean mass?

This tool uses body weight for simplicity. For athletes, lean mass can be a useful refinement with coaching.

Does timing matter or is total daily intake the key?

Total daily intake matters most for many people. Distributing protein across meals can make targets easier to reach.

Is more protein always better?

Not always. Higher targets can help specific goals, but benefits vary. If you have medical conditions, follow professional guidance.

Key takeaways

  • Protein needs scale with body weight and training load
  • Activity sets a baseline grams per kg target
  • Goals can shift the target within reasonable bounds
  • Charts help you visualize your target versus a max reference
  • Save scenarios to compare changes over time
