Weighing every ingredient is the most precise way to track, and it is the main reason people stop. Nobody brings a scale to a restaurant, a work lunch or a family dinner. The good news is that for most goals you don’t need to.
Consistency beats precision
A log that is roughly right every day tells you far more than a perfect log kept for three days. Over a few weeks, the same small estimating error tends to repeat, so trends in your weekly average, and in your weight, stay meaningful. What ruins a log is gaps: the skipped weekends, the dinners out you never entered.
Estimate portions with things you always have
Hands are a surprisingly consistent measuring tool because they scale with your body:
- Palm (thickness and size, no fingers): a portion of meat, fish or tofu.
- Fist: a portion of rice, pasta, cereal or fruit.
- Cupped hand: a portion of nuts, dried fruit or crisps.
- Thumb: a portion of butter, oil, peanut butter or cheese.
These are rough, and that’s fine. Use them to sanity-check an estimate, not to replace one.
Let a photo do the first draft
Photo logging turns estimating into checking. Instead of working out a portion from scratch, you photograph the plate and a calorie app lists each food with a portion. You only have to decide whether each line looks right. With Fitto AI that is one photo per meal, and you can change any portion before it is logged.
For meals that are hard to photograph, describe them instead: “two slices of margherita pizza and a side salad with ranch”.
Where precision still matters
- Oils, butter and dressings. These are the most calorie-dense things you eat and the hardest to see. Add them on purpose.
- Packaged food. Scan the barcode or copy the label. Printed values beat any estimate.
- Foods you eat every day. If your breakfast never changes, weigh it once and reuse that number.
Keep going past week two
The first two weeks of tracking are the easy part. What keeps a log going is making it quick and not feeling judged by it. Log the heavy days too. They are the most useful data you have, and a tracker should never make you feel you have to hide them.
