Are you eating more protein because someone told you to, without knowing how much more? Does a number like one hundred and fifty grams mean anything to you in food terms? The Protein Intake Calculator gives you a daily target and shows what it looks like on a plate.
Protein is the macro people most often get wrong in both directions. A target you can picture is far more useful than a rule of thumb.
Short answer: The Protein Intake Calculator is free on EizTools, and it works out your daily protein target from your bodyweight, goal, activity level and diet, then breaks it into meals and suggests foods that get you there.
What is Protein Intake Calculator?
It answers a single question with context attached: how much protein should you eat each day? You describe your weight, your training and how you eat, and the Protein Intake Calculator returns a target, usually as a range, with the reasoning and a breakdown across your meals.
How Does Protein Intake Calculator Work?
- Type your details in the prompt, such as weight, training frequency and diet preference.
- Choose which AI engine runs the numbers.
- Set Unit System, Goal, Activity Level and Diet Preference in the advanced options.
- Generate, then read the target in the card below.
- Copy the numbers or export them as TXT, Word or HTML to keep with your food log.
Runs from today are held in the panel below, so a fat loss target and a muscle gain target sit next to each other.
The Options And What They Change
| Option | What it controls | Where to start |
|---|---|---|
| Unit System | Whether you get kilograms, pounds or grams per unit of bodyweight | Grams per kg, the format most research uses |
| Goal | Which target range applies | Muscle gain, Fat loss or Maintenance, honestly chosen |
| Activity Level | How much training raises the requirement | Strength training if you lift twice a week or more |
| Diet Preference | Which foods the suggestions use | Vegan or Vegetarian if animal sources are out |
Four toggles are worth knowing: break the target down per meal, suggest protein food sources, show a range instead of a single number, and note timing around workouts. The range option is the one to keep on, because a band is more honest than a false decimal.
Useful because
- It gives a range with reasoning, not just a figure
- The per meal breakdown makes the target achievable
- Food suggestions match your diet, including plant based eating
- Free to run as often as your weight or training changes
Keep in mind
- Targets are general guidance, not a clinical prescription
- Kidney or liver conditions change the picture entirely
- It relies on the bodyweight and activity you report
When People Run It
- Starting resistance training and wanting to eat enough to recover.
- Dieting and trying to keep muscle while calories drop.
- Going vegan and checking whether the day still adds up.
- Older adults told to protect muscle mass and given no number.
- Recovering from surgery or illness with higher protein needs.
Hitting The Target In Practice
- Spread it across meals. Thirty to forty grams per meal is easier than one huge dinner.
- Anchor each meal with a protein source before you plan the rest.
- Weigh a few portions once so you learn what the numbers look like.
- Do not chase the target on holiday. Weekly averages are what matter.
Note These targets are general fitness guidance. If you have kidney disease, liver disease or any condition that affects protein handling, ask your doctor or dietitian for a figure before changing your intake.

Frequently Asked Questions
How much protein do I actually need?
Most active adults land between 1.6 and 2.2 grams per kilogram of bodyweight. Sedentary adults need less, and the tool adjusts the range for your activity level.
Should I calculate from bodyweight or goal weight?
Goal weight is the more sensible base if you are carrying a lot of extra weight. Say which you used, so the number means what you think it means.
Can I hit a high target on a vegan diet?
Yes, though it takes planning. Set Diet Preference to Vegan and the suggestions shift to tofu, tempeh, seitan, legumes and soy products with realistic portions.
Does timing around workouts matter?
Less than total daily intake. Turn on the timing note if you train twice a day or fast for long periods, otherwise focus on the daily figure.
Protein targets work best when they turn into a habit rather than a spreadsheet. Get the range, anchor each meal, and check back only when your weight or training changes noticeably.
The calculator is above this article. Enter your weight, your training and your diet, and read your range.
