My grandmother could not understand why I ran. She also could not understand why the dal at lunch mattered so much to me on Sundays after a long run. 'It is just dal,' she said. 'You have eaten it your whole life.' She was right, of course. And also wrong. The dal had always been there. What changed was what my body was asking it to do.
This is an article about protein, but really it is about what the body does with what you give it after you ask it to run for two hours. The science is clearer than most popular nutrition writing admits. It is also less dramatic.
What the body actually needs
The protein needs of endurance runners are higher than the sedentary recommendation. Most sports nutrition reviews converge on a range of roughly 1.2 to 1.8 grams of protein per kilogram of body weight per day for endurance athletes in training, with the upper end of that range supported for runners doing heavy mileage or in a calorie deficit. For a 60-kilogram runner, that is 72 to 108 grams per day. For an 80-kilogram runner, 96 to 144.
This is not the same as what bodybuilders need. Endurance runners do not need to eat protein the way someone training for a powerlifting meet does. But they need more than the general adult recommendation, and the gap matters because under-eating protein during a training block compromises recovery, immune function and, over time, the strength of the connective tissues that hold the running gait together.
What the research finds about timing
The 'anabolic window' that dominated gym culture for a decade has been quietly revised in the research community. Recent reviews suggest that the post-exercise window for protein consumption is longer than the urgent thirty minutes once promoted — closer to a few hours — and that total daily protein intake and its distribution across meals matters more than urgency in the first half hour.
That said, consuming 20 to 30 grams of protein within an hour of a long run remains a useful practice. It is not magic. It is just convenient timing to start the process while you also restore carbohydrate.
Indian diets and the protein question
Here is where Indian sports nutrition gets specific. The vegetarian, lacto-vegetarian and largely-vegetarian-with-some-eggs diets that many Indian runners follow can absolutely meet a runner's protein needs. They do require attention.
Three principles, all backed by reasonable research consensus.
Spread protein across meals
The body uses protein most efficiently when it is distributed across three to four meals containing 20 to 40 grams each, rather than concentrated in one large meal. A typical Indian eating pattern of small breakfast, large lunch, light evening snack and dinner can struggle here. The fix is not dramatic. A scoop of paneer or a dal-and-egg combination in breakfast, a substantial protein source in lunch, and a deliberate protein-containing snack in the late afternoon all help.
Combine plant proteins
The notion of complementary proteins is overstated in popular writing but is not wrong. Different plant sources contain different amino acid profiles. Rice and dal together provide a more complete amino acid mix than either alone. Idli with sambar. Khichdi with curd. Roti with rajma. Indian cuisine has been doing this combination for centuries without theory. The theory is interesting. The eating is what matters.
Watch for the protein gap
The runners who most consistently undereat protein are vegetarian women in their twenties and thirties training for distance events. A bowl of poha, a chapati and sabzi for lunch, a fruit in the evening and a small dinner can leave you at 40 to 50 grams of protein for the day. That is not enough to support hard training. Add yogurt, paneer, dal at two meals, sprouts, soya chunks, occasionally protein powder, and you can comfortably reach 80 to 100 grams without restructuring your diet.
What I learned the hard way
In 2022, a coach who watched me struggle through the second half of long runs in Mumbai's January cool asked me what I had eaten the day before. I rattled off a list. He listened, then said, 'You ran twenty-five kilometres yesterday and you ate sixty grams of protein. That is your problem.'
He was, more or less, right. The next month I tracked. I had been chronically under-eating protein for months. Once I started hitting 90 to 100 grams a day, the post-long-run soreness reduced. Easy runs felt easier the day after a hard session. I do not believe protein was the only variable. I do believe it was a meaningful one.
The supplement question
Whey or plant-based protein powders are not necessary for most runners. They are convenient. A 25-gram serving of whey provides protein density that is logistically simpler than packing paneer at the office. If your diet hits the daily target without a powder, you do not need one. If it does not, a powder is a reasonable bridge.
Quality varies widely in the Indian market. Choose whey or plant protein from brands with third-party testing. Read the label. A protein powder that is 60 percent protein by weight is not a protein powder — it is a carbohydrate powder with some protein in it.
The bigger picture of recovery
Protein is one input. The full recovery system has others, and pretending that protein alone is the lever is the kind of fitness oversimplification that sells supplements but does not improve running.
Carbohydrate replenishment matters at least as much for endurance recovery. A long run depletes muscle glycogen. Restoring it within hours of finishing accelerates recovery for the next session. A meal with 60 to 90 grams of carbohydrate and 20 to 30 grams of protein within an hour of a long run is a sound general practice.
Sleep matters more than supplementation. The literature is consistent. A runner sleeping seven hours instead of nine is leaving more on the table than one missing a protein scoop.
Strength work matters in a way that protein cannot replace. Two short strength sessions a week support tendon and muscle resilience in ways that nutrition alone does not. The exercises page walks through the essentials for runners, and the recovery guide places nutrition in the wider context.
When to see a doctor
If you are doing the work and still feel exhausted, sore for days, or losing pace inexplicably, a blood panel may reveal what intuition cannot. Low ferritin, B12 deficiency, and vitamin D insufficiency are all common in Indian runners, particularly women. A nutrition fix without a blood test can miss the actual problem. The injuries and health page covers when to seek medical input.
A practical plan for next week
Here is what to try, starting tomorrow, if you are training for a half or full marathon.
Eat protein at every meal. Aim for 20 to 30 grams. Yogurt at breakfast. Dal or paneer or eggs at lunch. A handful of nuts or a glass of milk in the evening. A protein source at dinner. Track for three days to see where you land. Most runners are pleasantly surprised that they are not as short as they feared. Some are unpleasantly surprised that they are.
After your long run, eat within an hour. The traditional Indian post-run lunch — rice, dal, sabzi, curd, sometimes a roti — is, frankly, an excellent post-long-run meal. It has carbohydrate, protein, some fat, and enough volume to refuel.
Keep the running plan ambitious and the nutrition honest. The combination is what gets you to race day intact.

What my grandmother said about the dal was true. It had always been there. What changed was that I started paying attention to whether I had eaten enough of it.
