What 90g of protein actually looks like

Four plates, with the label arithmetic printed beside each one, because grams are abstract and dinner is not.

Why plates and not grams

Ninety grams of protein is a number without a picture. Nobody eats a number. This page turns it into four plates so the quantity stops being abstract - and shows the addition, so you can check it and then do your own.

A note before the arithmetic: 90g is the illustration, not the recommendation. What you should eat depends on your size, your activity, your age and your health. If you want a figure for yourself, the Australian Dietary Guidelines are where the official one comes from, and an Accredited Practising Dietitian is where a personal one does.

How to read the label you already have

Every packaged food carries protein per 100g on the Nutrition Information Panel. That is the figure to use, rather than the per-serve column, because the manufacturer chose the serve size and you did not.

The arithmetic is one line:

> grams of food ÷ 100 × protein per 100g = protein in what you ate

Weigh the food, or take the pack weight if you ate the lot. Both are easier than trusting a serve size that was decided in a marketing meeting.

Four plates

Each of these is built from the per-100g figure on the packet. Read your own packets - brands differ, and the point of this exercise is that you can do it yourself in ten seconds.

Plate one, omnivore. A chicken breast, a serve of rice, a spoon of yoghurt. Weigh the chicken raw, read the per-100g figure, multiply. Then the yoghurt. The rice contributes less than people expect but it is not zero, and it is on the packet too.

Plate two, vegetarian. Lentils, eggs, a slice of bread with peanut butter. The lentils are the surprise here: check whether the panel quotes them dry or cooked, because the two differ by roughly a factor of three and getting that backwards is the single most common error on this page.

Plate three, low budget. Tinned beans, eggs, milk. Every one of the three is among the cheapest protein per gram in a normal supermarket, and every one carries the figure on the tin.

Plate four, no cooking. Skyr or Greek yoghurt, a tin of fish, nuts. Nothing here needs a hob.

The rounding trap

Raw or cooked changes everything. Meat loses water when cooked, so the protein per 100g goes up; dry pulses and grains absorb water, so it goes down. The panel quotes one state or the other and usually says which in small print.

Use the state the packet describes and weigh the food in that state. Mixing the two is how people end up thinking they ate half of what they did, or twice.

Build your own from four slots

A protein-forward plate is usually the same four components: a main protein, a dairy or pulse, a carbohydrate that carries some, and something on top. Fill the four slots, read four packets, add four numbers. No app is involved and none is needed.

The limits of this piece

Settled enough to state

How to add up the protein in a meal from the per-100g figure already printed on the packaging, and how much raw versus cooked moves the total.

Depends on you

How much protein you should eat. It varies with body size, activity, age and health, which is why this page uses 90g as an illustration and not a target.

Not something a webpage can answer

Whether you personally are eating enough of anything. That needs someone who can look at your whole diet and your bloodwork, not a worked example.
