Protein Requirements
Protein Calculator — Daily Protein Intake Calculator Free
This free protein calculator determines your exact daily protein intake based on your weight, goal and activity level. Whether you want to lose fat, maintain muscle or build mass, your protein requirement calculator result gives you a personalised gram target — not a generic number.
Most adults need between 1.2–2.6g of protein per kg of body weight per day. The exact amount depends on your goal — weight loss requires more protein (to preserve muscle during a calorie deficit) while maintenance needs less. This protein intake calculator adjusts for all goals.

How Much Protein
How Much Protein Do I Need? — Protein Per Day by Goal
Daily Protein Intake by Body Weight
The answer to how much protein do I need depends on what you're trying to achieve. Here is the research-backed breakdown by goal:
| Goal | Protein (g/kg) | For 70kg person | Why |
|---|---|---|---|
| Sedentary adult | 0.8–1.0 g/kg | 56–70g/day | Minimum for organ function |
| Weight loss | 1.6–2.4 g/kg | 112–168g/day | Preserves muscle during deficit |
| Maintenance | 1.2–1.8 g/kg | 84–126g/day | Sustains muscle mass |
| Muscle gain | 1.8–2.6 g/kg | 126–182g/day | Maximises muscle protein synthesis |
| Athlete | 2.0–3.0 g/kg | 140–210g/day | Performance and recovery |
| Healthy ageing (60+) | 1.4–2.0 g/kg | 98–140g/day | Prevents sarcopenia |
How much protein per day for Indians specifically? Most Indians eat only 40–55g/day — well below what's needed for active individuals. Bridging this gap is the single most impactful dietary change most Indians can make for their health and body composition.
Muscle Gain
Protein Calculator for Muscle Gain — Protein Calculator for Weight Loss
The protein calculator for muscle gain recommends 1.8–2.6g/kg — significantly higher than maintenance levels. This range is supported by a 2017 meta-analysis in the British Journal of Sports Medicine (NIH/PubMed) covering 49 studies and 1,800 participants. WHO protein deficiency guidelines highlight that India has one of the highest rates of protein undernutrition globally.
Protein Calculator for Weight Loss
When cutting calories, your protein calculator for weight loss result will be at the higher end — 1.6–2.4g/kg. This is because protein has the highest thermic effect of food (TEF) — your body burns 20–30% of protein calories just digesting it. High protein also maximises satiety, reducing hunger on a calorie deficit. Most importantly, it preserves lean muscle mass — ensuring the weight you lose is fat, not muscle.
| Tip | Detail |
|---|---|
| 30–40g per meal | Your body can only use ~25–40g for muscle protein synthesis per meal — spread it across 4 meals |
| Leucine content | Animal proteins (eggs, chicken, whey) trigger muscle protein synthesis more than plant proteins |
| Distribute evenly | Spread protein across 4 meals rather than front-loading or back-loading |
| Post-workout timing | Protein within 2 hours amplifies muscle protein synthesis — but total daily intake matters most |
Women & Men
Protein Calculator for Women and Protein Calculator for Men
The protein calculator for women uses the same formula as men but accounts for lower average body weight and lean mass. Women generally need 10–15% less total protein than men of the same height and activity level — but the per-kg target is identical.
Protein calculator for men: Men typically have 15–20% more muscle mass than women, meaning higher absolute protein needs. For an 80kg active Indian man targeting muscle gain, the protein requirement is typically 144–208g/day — most Indian men fall dramatically short of this.
Both men and women benefit equally from adequate protein for weight loss, with studies showing high-protein diets (1.6g+/kg) produce 50% more fat loss than low-protein diets at the same calorie deficit.
This protein per day calculator is particularly useful for Indians — the protein calculator India benchmark shows most Indians consume only 40–55g daily, far below the optimal 1.6–2.6g/kg. Whether you're a gym-goer using it as a protein calculator bodybuilding tool or tracking daily intake as a protein macro calculator, the result gives you a personalised gram target — not a one-size-fits-all recommendation.
