Judging portion sizes without a scale

2 min read

You will not always have a scale, and rough estimates logged consistently are more useful than perfect ones logged rarely. Your hand travels with you and makes a handy guide: a palm is roughly a portion of protein (about 85–100 g of meat or fish), a cupped hand a portion of carbohydrate like rice or pasta, a fist a portion of vegetables, and a thumb a portion of fats like oil, butter or nut butter.

Some other everyday anchors: a medium piece of fruit is about a tennis ball, a portion of cheese about two thumbs, and a teaspoon of sugar or oil about the tip of your thumb. Bigger hands tend to go with bigger bodies and appetites, so the guide scales with you.

When you log, pick the closest serving and adjust the quantity — over a week the small over- and under-estimates tend to average out. Weighing a few common foods once helps you calibrate your eye for next time.
