Protein Intake Calculator by Exercise Goal and Food Table

The practical formula is simple: body weight in kilograms multiplied by a goal-based protein factor. A healthy sedentary adult can start from 0.8 g/kg, while active lifters often plan around 1.4 to 2.0 g/kg/day. This is a planning guide, not a medical prescription. People with kidney disease, liver disease, pregnancy, recovery needs, or clinical nutrition concerns should use professional advice first.

Quick Formula

For a 70 kg adult, 0.8 g/kg equals 56 g per day. Light training may use 1.2 to 1.4 g/kg, or 84 to 98 g. Muscle gain with regular resistance training may use 1.6 to 2.0 g/kg, or 112 to 140 g. Cutting phases often keep protein high to protect fullness and lean mass, but total calories, sleep, fiber, and training quality still matter.

Goal Table

Food Protein Table

Chicken breast provides about 30 to 32 g per cooked 100 g. One egg provides about 6 to 7 g. Greek yogurt provides about 15 to 18 g per 170 g cup. Tofu provides about 24 to 30 g per 300 g block. Tuna, salmon, lean beef, lentils, milk, and protein powder can fill gaps, but product labels should be checked because sauces, water content, and serving size change the real number.

Practical Meal Placement

Do not place the whole target into one meal unless it fits your digestion and schedule. A 100 g target can become 25 g at breakfast, 35 g at lunch, 20 g after training, and 20 g at dinner. This keeps the plan easier to repeat. Connect the plan with internal tools such as /tools/bmi-calorie, /hubs/health, /tools, and /blog when building a broader health workflow.

Practical Insight

Many people fail because they calculate the perfect number but never translate it into meals they can repeat. Pick one anchor protein per meal first: eggs and yogurt for breakfast, lean meat or fish at lunch, tofu or chicken at dinner, and a small shake only when the day is short. For a 70 kg beginner, holding 100 g for two weeks is often more useful than forcing 140 g on day one and quitting because digestion, cost, and boredom become too high.

FAQ

Q1. What is the protein formula?

A. Multiply body weight in kilograms by the goal factor, such as 0.8, 1.4, or 1.8 g/kg.

Q2. Is 0.8 g/kg enough for everyone?

A. It is a baseline for healthy adults, not a universal athletic target.

Q3. Do lifters need more?

A. Regular resistance training often uses 1.6 to 2.0 g/kg/day.

Q4. Is protein powder required?

A. No. It is only a convenient supplement when meals are short.

Q5. Can plant protein work?

A. Yes, if total intake and variety are planned well.

Q6. Can high protein be unsafe?

A. People with medical conditions should get clinical advice before raising intake.
