Protein around the workout: the daily total matters more than the “post-workout window”
A shaker in the changing room, “before the window closes” — a ritual that outlived the science. Muscle protein synthesis remains elevated for 24-48 hours after strength training, not 30 minutes; the muscle needs protein throughout this period, not one portion grabbed on the go. This changes everything: the daily total and distribution matter, not the stopwatch. Section — strength and nutrition.
1,6-2 g/kg
per day with strength training
30-40 g
per meal
24-48 h
post-workout window
3-4
protein-containing meals
Why a threshold per meal?
Muscle protein synthesis is triggered by leucine — an amino acid needed in an amount of 2,5-3 g at a time, equivalent to 30-40 g of complete protein: 150-200 g of meat or fish, 5 eggs, or 200 g of cottage cheese. 15 g does not trigger it. 100 g at once triggers it only once; the rest is used for energy. Hence three to four meals of 30-40 g, rather than “all the protein at dinner.” After 45, the threshold is higher — closer to 40.
Sources: where to get 30 g of protein
| Food | Serving for 30 g of protein | Note |
|---|---|---|
| Chicken, turkey | 130-150 g | lean |
| Beef, pork | 150 g | plus iron and creatine |
| Fish | 150 g | oily — plus omega-3 |
| Eggs | 5 eggs | plus choline |
| Cottage cheese 5-9% | 200 g | casein — slow-digesting, good for dinner |
| Hard cheese | 100 g | plus fats and calcium |
| Whey isolate | 35 g of powder | when food is not enough |
Around the workout according to the method
Training after eating: have a meal with protein 1-2 hours beforehand, then eat your next regular meal afterward. Training at the end of a fasting window: make your first meal afterward contain 30-40 g of protein, within an hour or two, not “immediately.” Protein powder is food in powdered form, not a supplement: you need it if you cannot reach 1,6 g/kg from food, and do not need it if you can. BCAAs are useless with complete protein. Fasted or fed — training fasted or after eating. Protein basics — protein on a low-carbohydrate diet.
Mistakes
- 60 g of protein per day with three strength sessions
- All protein at dinner
- Protein powder instead of food three times a day
- Cutting protein during a calorie deficit — muscle is lost
- Fearing “excess protein for the kidneys” — 2 g/kg is safe for healthy people
Frequently asked questions
Casein at night?
Cottage cheese at dinner is slow-digesting protein for 6-8 hours and helps overnight synthesis. Powdered casein is not necessary.
Plant protein?
You can, but it contains less leucine and is absorbed less efficiently: make portions 30-40% larger and combine sources. For muscle growth, animal protein is more effective.
Protein and fasting — a conflict?
No, if there are three meals of 30-40 g within the window. With a 6-hour window, have three meals 2-3 hours apart.
- DOMS or injury: how to tell growth from damageDull muscle pain on the second day — growth. Sharp joint pain at the moment it happens — injury. Between the two — overtraining. A table of differences and what to do in each case.
- Creatine for women: the only sports supplement with dataHundreds of studies, plus strength and muscle volume; after 45 — plus bones and memory. 3-5 g per day, no loading phase, plus a kilogram of water in the muscles during the first month. Why women need it even more.
- Training Fasted or After Eating: What the Data ShowsWith this method, strength training often falls at the end of the fasting window. Strength is slightly lower, muscle growth is the same with protein afterward. When training fasted works, when it backfires, and how to structure your day.
- Warm-up and mobility: 8 minutes that protect your jointsStretching before strength training reduces strength by 5-10% and does not protect against injuries. What to do instead: raise your temperature, move your joints, and perform warm-up sets. And why mobility should be separate.
- Sets, reps, and rest: the numbers that determine results3 sets of 6-12 with a weight that makes the last two reps hard, 2-3 minutes between sets — the formula for growth. Why short rest «for fat burning» steals results, and when to change the range.
- Load progression: the only law without which muscle doesn’t growThe same weight for six months — the body adapted by the second month. Add a kilogram, a rep, or a set every week — and growth doesn’t stop. How to build progression and what to do when it stalls.
