Protein portions are easy to get wrong because protein foods come in such different shapes: a chicken breast, two eggs, a pile of lentils, or a block of tofu do not look alike at all. Yet one portion of most of these foods weighs about one hundred grams, or about eighty grams for cooked beans and lentils. This free visualizer shows one portion for each food in grams, in everyday amounts, and against your palm. With that picture in mind, you can judge a portion at home, in a restaurant, or at a friend house, without carrying scales.
Your palm is the secret tool here, because it scales with your body in a rough but useful way. A piece of chicken, fish, or beef about the size and thickness of your palm weighs close to one hundred grams for most adults. Eggs break the palm rule, which is why the tool gives them as a count instead: two eggs make about one portion. Beans and lentils use spoons, since three heaped tablespoons of cooked lentils weigh about eighty grams. The tool gives you the right comparison for each food, instead of forcing one rule onto every food.
Using the tool takes seconds. Pick your protein food, set your servings, and press the button. The result shows the food name, one portion in grams, an everyday amount such as one small fillet or two eggs, a hand comparison, and the total weight for your servings. Use it while you shop, to decide how many chicken breasts or how much tofu to buy, or while you cook, to split a pack fairly between plates. Change the food and compare, so you learn that a lentil portion and a chicken portion can weigh nearly the same while looking very different.
Variety matters as much as size when it comes to protein foods. Chicken, fish, eggs, beans, lentils, and tofu each bring different flavours, textures, and nutrients, so rotating them across a week keeps meals interesting and balanced. The tool helps with that rotation, because you can check a portion for an unfamiliar food before you cook it. If you have only ever portioned chicken by eye, checking lentils first stops you from serving a tiny spoonful or a mountain, and it makes trying a new protein food feel safe rather than risky.
One common mistake is serving protein by the pack instead of by the portion. A pack of chicken breasts may hold two portions per breast, and a block of tofu may hold two or three portions, so eating a whole pack piece is not always one portion. Another mistake is forgetting that coatings, sauces, and frying add weight and energy without adding protein. The tool measures the plain food, so judge coatings separately. Splitting packs at the shop, or right after cooking, makes fair portions much easier than trying to guess on a full plate.
At restaurants and takeaways, the palm comparison becomes your best friend. Compare the meat or fish on your plate with your palm, and you will know at a glance whether it is about one portion, closer to two, or a smaller piece that pairs well with extra vegetables and grains. You do not need to weigh anything or ask the kitchen awkward questions. Just look, compare, and enjoy the meal. If the piece is much larger than your palm, sharing, saving half, or adding more vegetables are all simple, normal options.
This tool is general food education only. It does not diagnose, treat, or give personal diet advice, and its portions are guide averages, not targets for any individual. If you follow a special diet for medical reasons, speak to a qualified professional about your own needs. For everyday meals, the visualizer is a fast, practical aid that builds a lasting skill. Learn the palm picture, the two-egg count, and the three-spoon bean measure, and protein portions will stop being guesswork.
Start with the protein food you eat most often this week. Check its portion in the tool, compare it with your palm or your usual serving, and adjust only if the gap is large. Then try one food you rarely cook, such as lentils or tofu, and check its portion before you buy it. That small step makes new foods less intimidating and old favourites easier to portion. Keep the tool bookmarked, and return to it whenever a new protein food joins your weekly shop.
