Palm, fist, cupped hand: the hand method for protein, carbs and vegetables — plus the one protein number per meal that you genuinely need.
The short answer: you need exactly one number, and you do not have to weigh it. Plan each meal around 0.4 g of protein per kilogram of body weight across at least four meals [1] — at 80 kg that is 32 g per box. Everything else on the plate can be measured with your own hand.
One palm of protein, one cupped hand of carbohydrates, two fists of vegetables, one thumb of fat. This hand method is practical knowledge from dietary counselling, not a measuring technique — there is no validation study for it, and that deserves saying. As an everyday approximation it is still unbeatable.
The kitchen scale is not wrong. It is just almost never there when you need it. And meal prep rarely fails on imprecise grams — it fails because after two weeks nobody wants to weigh every single ingredient any more.
Take your body weight times 0.4 — that is your protein target per meal, spread across at least four meals a day [1]. At 60 kg that is 24 g, at 80 kg 32 g, at 100 kg 40 g.
The sports nutrition society gives the same order of magnitude: 20 to 40 g per portion, or 0.25 g per kilogram of body weight [2].
What 32 g means in practice: about 150 g of chicken breast, 200 g of low-fat quark, a large pot of skyr plus an egg, or a generous ladle of lentils with some cheese. Memorise two or three of these anchors and you will never need a table again.
The rule of thumb for a complete plate, again as a practical value with no claim to study backing:
A typical meal-prep box: one to two palms of protein, one to two cupped hands of carbohydrates, two fists of vegetables, one thumb of fat. If you train hard, add to the carbohydrates, not to the fat.
The trick that turns guesswork into a system: weigh one single time what your palm of chicken actually weighs and how much cooked rice fits into your cupped hand. Write those two numbers down.
From then on you are not estimating, you are remembering. Your hand is now calibrated.
Starting values from practice: 60 to 80 g of dry rice or pasta per portion, 60 to 80 g of oats for breakfast, 200 to 300 g of potatoes. With a high training volume, aim at the upper end.
Almost every portion figure online means dry, almost every hand measure means cooked. Swap them and you land at three times or one third of what you wanted.
Rough conversion from kitchen practice: rice triples its weight when cooked, pasta roughly doubles, lentils sit in between. So 70 g of dry rice becomes a good 200 g cooked — exactly one cupped hand.
Honest answer: for most people, no. Structure, enough protein and vegetables in every box will take you further than three weeks of app discipline followed by quitting.
And more is not better either: above a total intake of 1.62 g of protein per kilogram per day (confidence interval 1.03 to 2.20), extra protein delivers no further gain in lean mass [3]. So you do not need to maximise, you need to hit the number reliably.
Counting is a temporary tool — two or three weeks to build a sense of quantity. Not a permanent state.
This guide does not replace medical or dietary advice. The amounts given are orientation values for healthy, training adults.
With conditions that affect nutrition — diabetes, kidney disease, coeliac disease — as well as in pregnancy and breastfeeding and for children and adolescents, portion and protein questions belong in professional hands, not in a hand-measure scheme.
And one point that matters more than any number: if portions start to feel like control, guilt or compulsion, if you skip meals, eat secretly, want to compensate after eating or constantly think about counting, those are warning signs of disordered eating. The next step then is a doctor or a qualified dietitian, not the next app.
Chronically low energy intake is a risk too, not a shortcut: it shows up in bone density, resting metabolic rate, menstrual disturbances, mental health, and in strength and endurance [4]. If you are losing performance while losing weight, you are doing something wrong — not too little.
Do not calibrate the portion, calibrate the box. Fill your standard container once the way it should be, weigh it, and mark the fill height with a waterproof pen. From then on you do not measure, you fill to the line.
The second trick for boxes with several components: think in quarters. One quarter protein, one quarter carbohydrates, half vegetables. You can check that by eye in two seconds, and it lands surprisingly close to the hand-measure maths.
If you would rather have real grams: the nutrition plan in the DOMISPORTS training centre calculates the amounts from your weight and training load — and this guide then translates them into hands, so you can apply them on the move.
As a practical value, 60 to 80 g dry per person and meal, more with a high training volume. Cooked, that comes to roughly one heaped cupped hand. What matters is committing to one unit: measuring dry and estimating cooked will triple your portion in the wrong direction.
As an approximation yes, as a measurement no. There is no validation study for it — it is a widespread heuristic from counselling practice. Its advantage is not accuracy but availability: your hand comes with you to the restaurant, the hotel and the canteen. For the protein part you should calibrate once in addition [2].
No. For most people a fixed meal structure, enough protein per meal [1] and two fists of vegetables are enough. Counting can make sense as a time-limited learning tool to build a sense of quantity. As a permanent state it costs more discipline than it delivers in results — and for some people it tips into compulsion.
Beyond roughly 0.4 g per kilogram of body weight per meal the muscle-building benefit is largely exhausted [1], and above 1.62 g per kilogram per day extra protein brings no additional gain in lean mass [3]. A bit more is not harmful with healthy kidneys, it is simply ineffective and expensive.
