There is no single protein target that fits everyone who trains. Your body size, training, overall diet and goal all matter, which is why useful guidance is normally expressed as a range rather than one magic number.
For healthy adults doing regular resistance or endurance training, sports-nutrition guidance commonly places daily protein intake around 1.2–2.0g per kilogram of bodyweight, with needs varying by the type and volume of training. That gives you a sensible starting point to adjust around your own diet rather than a target to chase at any cost.
Start with your whole day, not your post-workout shake
The easiest mistake is to focus on the drink after training while ignoring the other 23 hours of the day. Protein contributes to the growth and maintenance of muscle mass, but your overall intake and training matter more than hitting an exact minute after your last set.
For an 80kg person, a broad 1.2–2.0g/kg range works out at roughly 96–160g across the day. That is deliberately a range. Someone doing a few gym sessions each week may land differently from an athlete with a high training volume.
Does your goal change the amount?
It can. Resistance training, endurance training and periods of reduced energy intake place different demands on the diet. Rather than automatically pushing to the highest possible number, use the lower and upper ends as context and make sure the rest of your diet still has room for carbohydrate, fats, fruit, vegetables and the foods you enjoy.
If you have a specific performance, body-composition or medical goal, a registered sports dietitian can help turn general guidance into something appropriate for you.
How should you spread protein through the day?
You do not need to eat your entire daily intake in one sitting. In practice, building meals and snacks around a useful protein source makes the target easier to reach and avoids the end-of-day scramble to make up a large shortfall.
There is no need for every meal to contain an identical number of grams. Think in terms of a reasonably even pattern that works with your appetite and routine.
Do you need protein immediately after training?
No narrow countdown starts when your workout ends. Having a protein-containing meal or snack around training can be convenient, but total intake across the day remains important.
If you train before a normal meal, that meal may already cover what you need. If your next meal is hours away, a shake or another convenient protein food can bridge the gap.
Food first, powder when it is useful
Protein can come from foods such as meat, fish, eggs, dairy, soya, tofu, beans, lentils and other pulses. Protein powder is simply another convenient source; it is not compulsory for making progress.
If a shake fits your routine, choose it on the same basis as any other food purchase: check the serving information, ingredients, allergens, format and whether you actually like the flavour. Our whey concentrate versus isolate guide explains two common whey formats, while the whey protein buying guide covers the practical label checks.
If flavour is the uncertainty, a single-serving sample can make more sense than gambling on a full tub.
A practical way to estimate your intake
Use your bodyweight and a suitable evidence-based range as a starting point, then look at what you already eat. You may find you are already close without changing much.
For example, at 70kg the broad 1.2–2.0g/kg range is around 84–140g per day. At 90kg it is around 108–180g. Those numbers are illustrations, not personalised prescriptions.
Once you know roughly where your current diet sits, it is usually easier to add protein to one or two meals than to redesign your whole diet around shakes.
When general guidance is not enough
People with kidney disease or another medical condition affecting nutrition should get individual advice before making a substantial change to protein intake. The same applies if you are pregnant, breastfeeding or have been given a medically prescribed diet.
For everyone else, keep the priority simple: train consistently, eat a varied diet, get enough protein across the day and use supplements only when they make that routine easier.
