Vegan Macro Calculator: Hit Your Protein Goals on a Plant-Based Diet

Getting enough protein on a vegan diet requires intention. Plant proteins are generally less bioavailable than animal proteins, so many nutrition experts recommend vegans target 1.6–2.0g of protein per kg of bodyweight. Your macro calculator output gives you the gram targets. Prioritise legumes, tofu, tempeh, seitan, and edamame to hit those numbers.

Getting enough protein on a vegan diet is entirely possible, but it requires more planning than an omnivorous diet. Plant proteins are typically incomplete, meaning they lack one or more essential amino acids. The solution is simple: eat a variety of protein sources throughout the day. Rice and beans, hummus with bread, tofu with quinoa, these combinations provide a complete amino acid profile. You don't need to combine them in the same meal, just across the day. Vegans often need slightly more total protein than omnivores because plant proteins have lower digestibility, roughly 85 to 90 percent compared to 95 percent for animal proteins. Aiming for 1.8 to 2.2 grams per kilogram of body weight covers this gap.

Aim for 1.8 to 2.2 grams of protein per kilogram. Plant protein has slightly lower digestibility than animal protein, so a small buffer helps.
Eat a variety of protein sources daily. Legumes, tofu, tempeh, seitan, quinoa, and nuts each contribute different amino acids.
Supplement vitamin B12, and consider vitamin D, omega 3 from algae, and possibly iron and zinc depending on your diet.
Track your macros for the first few weeks to make sure you're hitting protein targets. Most new vegans underestimate how much they need to eat.

Learn More About Macronutrients

Understanding macronutrient distribution helps you optimize your nutrition for better health and fitness results.

What Are Macronutrients?

The three main nutrients your body needs in large amounts for energy and function.

Protein (4 calories per gram)

Essential for muscle building, repair, and immune function. Aim for 2.0g per kg of body weight.

Carbohydrates (4 calories per gram)

Your body's preferred energy source, especially for brain function and high-intensity exercise.

Fats (9 calories per gram)

Essential for hormone production, vitamin absorption, and long-term energy storage.

Food Sources

Examples of high-quality sources for each macronutrient.

Protein Sources:

Chicken breast, fish, eggs, Greek yogurt, beans, tofu, protein powder

Carbohydrate Sources:

Rice, oats, quinoa, sweet potatoes, fruits, vegetables, whole grain bread

Healthy Fat Sources:

Avocado, nuts, olive oil, fatty fish, seeds, nut butters

Practical Tips

How to successfully hit your macro targets every day.

• Prioritize protein at each meal to meet your daily target

• Time carbohydrates around your workouts for optimal energy

• Include healthy fats to support hormone production

• Use a food tracking app to monitor your intake accurately

• Prepare meals in advance to stay consistent with your targets

Frequently Asked Questions

What are macronutrients?

Macronutrients, or macros, are the three nutrients your body needs in large amounts: protein, carbohydrates, and fat. Protein supplies 4 calories per gram and is the building block for muscle and tissue repair. Carbohydrates also give 4 calories per gram and are your main fuel for the brain and high intensity work. Fat is the most energy dense at 9 calories per gram and is essential for hormone production and absorbing vitamins A, D, E, and K.

How should I split my macros for my goal?

For weight loss a common split is 40 percent protein, 30 percent carbs, 30 percent fat to preserve muscle in a deficit. For muscle gain try 30 percent protein, 50 percent carbs, 20 percent fat to fuel heavier training. For maintenance 30 percent protein, 40 percent carbs, 30 percent fat works well for most people. These are starting points. Adjust based on training type, hunger levels, and how your body responds over four to six weeks.

How much protein do I really need?

For sedentary adults the recommended daily allowance is 0.8 grams per kilogram of body weight. Active adults benefit from 1.2 to 1.6 grams per kilogram, and people in a calorie deficit or building muscle should aim for 1.6 to 2.2 grams per kilogram. A 70 kilogram lifter cutting fat would target around 140 grams of protein per day. Spreading protein across three to four meals of 30 to 40 grams each maximises muscle protein synthesis better than one or two large servings.

Do I need to track every meal?

Tracking every meal for two to three weeks teaches you what portions actually look like and where hidden calories live. After that most people can keep results with a hybrid approach: tracking protein and main meals, eyeballing the rest. Apps like MyFitnessPal or Cronometer make it easier, and weighing food gives the most accurate numbers. Long term tracking is not required for everyone, but it is the fastest way to understand your own intake patterns.

How do macros change between a cut and a bulk?

Protein stays roughly the same in absolute grams since the goal is to preserve or build muscle. Carbs and fat are the levers you adjust. In a cut you lower carbs and fat to create the calorie deficit while keeping protein high. In a bulk you raise carbs first since they fuel training and recovery, then add a little fat. A typical 70 kilogram lifter might eat 140 grams of protein either way, but go from 200 grams of carbs in a cut to 320 grams in a bulk.
