How to track calories without a scale

Weighing every ingredient is the main reason people stop tracking within a week. You do not need gram accuracy to see a pattern — you need the same rough method used consistently. These are the visual references dietitians use when no scale is available.

Visual references that work

1. 01Protein (chicken, fish, tofu, beef)

   Your palm, without fingers, is roughly a 100 g cooked serving for most adults. Thickness matters more than width, so compare against the depth of your palm too.

   Instead: One palm per meal covers most adult protein targets across three meals.

2. 02Carbohydrate sides (rice, pasta, potato)

   A cupped hand holds roughly 150 g of cooked rice or pasta. Restaurant portions are usually two to three cupped hands, which is where most underestimation happens.

   Instead: Fill a quarter of the plate rather than counting cups.

3. 03Fats (oil, butter, nut butter, cheese)

   The most underestimated group, because a splash of cooking oil can be 15 g of fat. Your thumb from tip to base is about one tablespoon.

   Instead: Measure oil with a spoon rather than pouring — the only place a utensil really helps.

4. 04Vegetables and fruit

   A closed fist is about one serving. Five fists a day is the practical version of the five-a-day reference point.

   Instead: Half the plate produce removes the need to estimate the rest precisely.

5. 05Packaged foods

   The label already did the maths. Read per-portion values and count how many portions the pack holds, rather than guessing weight.

   Instead: Note the number of portions before you start eating, not after.

Consistency beats precision: the same rough method every day reveals patterns that gram-accurate tracking for three days never will. Healthyish takes a photo instead — it estimates the portion for you and compares the composition with published WHO and USDA reference points, so there is nothing to weigh or search.

Healthyish provides nutrition information and educational context about eating patterns. It does not diagnose, treat, or predict any medical condition, and it does not give you a personal risk score. Estimates from photos are approximate. Talk to a doctor or dietitian about any health concern.
