How much protein do you actually need?
Protein is the one macronutrient where getting the amount roughly right genuinely matters if you are training. The good news is that the target is not complicated, and hitting it rarely requires supplements.
The range that matters
General guidance for people training regularly sits in the region of 1.6 to 2.2 grams per kilogram of bodyweight per day. Below that range you may limit your results; meaningfully above it, the extra does not appear to add much.
If you are in a calorie deficit, staying at the higher end of that range helps protect muscle while you lose fat.
Timing matters less than you think
The idea of a narrow window after training in which protein must be consumed has not held up well. What matters more is your total intake across the day, spread over three or four meals rather than concentrated in one.
Do you need a shake?
No. Powder is convenient and often cheaper per gram than meat, but it has no advantage over food. It is a practical tool for people who struggle to hit their target from meals alone, not a requirement.
- Chicken, fish, eggs, and dairy are all dense sources
- Lentils, tofu, tempeh, and beans work well on plant-based diets
- Combining plant sources across the day covers the amino acid profile
Key takeaways
- Aim for roughly 1.6–2.2 g per kg of bodyweight if you train regularly.
- Daily total matters more than post-workout timing.
- Supplements are convenient, not necessary.
