Do I need a food scale to count calories?

No, but it helps. A food scale is the most precise way to measure portions, especially for calorie-dense foods like oils, nuts, cereal, pasta and cheese. Many people weigh foods for a few weeks to learn what portions look like, then switch to estimating or using photos.

Should I weigh food raw or cooked?

Either works, as long as the nutrition entry you log matches. Raw weights are more consistent because cooking changes how much water food holds: 100 g of dry pasta becomes roughly 220 to 250 g cooked, and 100 g of raw chicken breast becomes about 70 to 75 g cooked.

What is a smart food scale?

A smart food scale connects to an app so the weight is sent to your food diary automatically, instead of you reading the display and typing it in. Some can also calculate nutrition. The Calori Scale goes further: it weighs each item on a plate separately and recognises what it is.

What is the best kitchen scale for weight loss?

Any digital kitchen scale that measures in 1 g steps, has a tare (zero) button and a flat platform big enough for a plate will do the job. Smart scales save time by logging the weight for you.

Smart food scales and weighing food

Weighing food is the most accurate way to count calories. This guide covers which foods are worth weighing, raw vs cooked weights, and what a smart food scale adds.

Why weigh your food?

Most people are not good at judging portions by eye. The foods where small mistakes matter most are the dense ones: a “splash” of olive oil can easily be 2 tablespoons and 240 kcal, a bowl of cereal is often double the 30 g on the box, and a handful of nuts can be anywhere from 100 to 300 kcal.

Weighing for a couple of weeks teaches you what portions look like. After that, many people only weigh the foods they get wrong most often.

Which foods are worth weighing?

Always worth it: oils, butter, nut butters, nuts, cheese, cereal, granola, pasta, rice.
Useful: meat and fish, bread you slice yourself, potatoes.
Rarely worth it: most vegetables and salad, where even a big mistake is only a few calories.
No need: anything packaged in fixed portions, where the label or barcode does the job.

Should you weigh food raw or cooked?

Both are fine as long as the nutrition you log matches what you weighed. Raw weights are more reliable, because how much water food gains or loses depends on how long it is cooked. If you batch cook, weigh the whole cooked pan, then weigh your portion and log it as a share of the total.

Food	Before	After cooking (approx.)	Why
Pasta, dry → boiled	100 g	220–250 g	Absorbs water
Rice, dry → boiled	100 g	250–300 g	Absorbs water
Oats, dry → porridge	40 g	200–250 g with milk or water	Absorbs liquid
Chicken breast, raw → cooked	100 g	70–75 g	Loses water
Beef mince, raw → cooked	100 g	65–75 g	Loses water and fat
Potatoes, raw → baked	100 g	75–85 g	Loses water

This is the most common logging mistake there is: weighing cooked rice or pasta and logging it as dry, which more than doubles the calories, or the other way round, which halves them.

How to weigh food quickly

Put your plate or bowl on the scale and press tare to zero it.
Add the first food, note the weight, and tare again.
Repeat for each food on the plate.
For oil and sauces, weigh the bottle before and after pouring.

It works, but logging each weight in an app afterwards is what makes it tedious. That is the problem smart scales set out to solve.

Normal kitchen scale vs smart food scale

	Kitchen scale	Smart food scale	Calori Scale
Weighs food	Yes	Yes	Yes
Sends weight to an app	No, you type it	Yes	Yes
Knows what the food is	No	No, you choose it	Yes, it recognises each item
Whole plate at once	One food at a time	One food at a time	Every item weighed separately

The Calori Scale

We are building the Calori Scale to remove the tare-and-type routine completely. Put down a full plate and a sensing layer under the glass reads where each item presses, so each one is weighed on its own. One photo from above tells Calori what each item is, and everything is logged to your diary with its weight and macros. It is coming soon, and you can join the waitlist on the Scale page.

No scale? Use a photo

If you do not want to weigh anything, an AI photo calorie counter is the next best thing. Calori estimates portions from a picture of your plate and logs the calories and macros in seconds. Many people use both: a scale at home for the dense foods, and a photo for everything else.
