Which side of the balance can a record hold?
One. Weight is usually described as the balance of what comes in and what the body uses, and only the first of those can be written down at home. Food can be weighed, labels can be read, a portion can be estimated and marked as one; what the body used in a day is an equation and an activity factor, within about 10 percent of measurement at rest for most people in the 2005 review by Frankenfield and colleagues, and a guess for the rest. A record can hold intake honestly. It cannot hold the other side at all.
That is why IZeat records food. Each meal with its rows and the source of a number on every one, the day as a list with a day total, the calorie target you chose and the calories left: the side you decide at the next meal, kept in a form you can correct. The number of the scale is a result of both sides over weeks, and a result is not something you act on at dinner.
Why is weight a poor thing to read every day?
Because a morning weigh-in is one reading of a body that is not only fat, and the reading moves from day to day for reasons that have nothing to do with the month's food. A single day on the scale is a poor answer to a question about weeks of eating; the record, read daily, is the instrument built for that question, and a run of weigh-ins read together tells a steadier story than any one of them.
| What you want to know | What food records tell you | What the scale tells you |
|---|---|---|
| Did today go the way I planned? | Yes, now: the total against the target, meal by meal | Nothing yet; a day's food is not a day's reading |
| What to do at the next meal | What is left, and where the day's calories went | Nothing: a number, with no rows under it |
| Whether the target was the right one | Only with the scale beside it, over weeks | Only with the record beside it, over weeks |
| Where the week drifted | Which day, which meal, which rows were estimates | That something drifted, at best |
Bottom line: the record answers now and says why; the scale answers later and says only how much.
Public health services describe the pace a scale is meant to show over time rather than a day: the CDC, read 14 September 2026, puts a gradual, steady loss at about 1 to 2 pounds a week and writes that people who keep to that pace "are more likely to keep the weight off than people who lose weight quicker". NHS services describe the same pace in metric, around 0.5 to 1 kg a week (The Royal Marsden NHS Foundation Trust, read the same day). At that pace a week's change is small, which is the argument for reading the scale over weeks and the record daily.
What do IZeat's week and month views show, and what do they leave out?
IZeat is the calorie tracker inside ChatGPT, Claude or any other assistant. Tell the assistant you already use what you ate instead of searching for foods and entering them one by one. The week and month views of the web app draw what was recorded: one bar per day, the target as a dashed line that steps when you change it, the average per recorded day with the count of recorded days beside it, and a day with nothing recorded, today included, as a gap, never a zero. The quarter and the year draw one bar per week, each week being its own average per recorded day. Ask the assistant for "the last four weeks" and IZeat's reply, which the assistant is asked to relay first under the "IZeat ·" prefix, gives the same: the range, how many of its days have entries, the average across those, and the target in force at the end.
What they leave out is weight. IZeat does not record it today, so there is no weight graph, no goal weight, no countdown and no line projecting where you would be in five weeks. That is not an oversight waiting for a feature: a projection is a promise about a result drawn from one side of the balance, and the record does not have the other side. If a weight measurement is recorded one day, it will sit beside the food as a fact, and the rules that hold for calories will hold for it: no red, no countdown, no verdict.
The useful pair today is the record and your own scale, read at the pace the scale deserves. Intake steady at the target you chose and weight steady over weeks is your maintenance calories observed; intake steady and weight falling is the deficit you meant; intake steady and weight flat for a month is the moment to read the record's estimated rows before anything else, and then, if the record holds up, to talk to someone qualified. Each of those readings is yours; the record's part was to make the intake side readable, day by day, with its sources.
Frequently asked questions
Short answers to the questions people type, each one sourced above.
Does IZeat track weight?
Not today. IZeat records food, meal by meal with the source on each item, and compares the day to the target you chose; there is no weight entry, no weight graph, no goal weight and no countdown. The week and month views draw intake per recorded day. A scale beside the record is still the useful pair, read over weeks rather than days, and the reading is yours to make.
Why does a weight loss app record food rather than weight?
Because food is the side of the balance you can act on at the next meal, and the only side that can be written down honestly: weighed, read from a label, or estimated and marked as such. Weight is a result of both sides over weeks, with more than food mixed in, and a result is not something you change at dinner. A record of intake tells you now what the week contained; the scale tells you later how much it added up to.
Why does my weight go up and down every day?
For reasons a food record cannot see. A single weigh-in is one reading of a body, and day-to-day readings move for reasons unrelated to the month's food; IZeat has no source of its own on those reasons and does not claim one. A run of readings read together tells a steadier story than any one day. The food record does not move with any of that, which is why it is the daily instrument, and the scale the slow one.
Will IZeat show me when I will reach my goal weight?
No. A projection draws a result from one side of the balance, intake, and the record never has the other side, what the body used, which is an estimate nobody measures at home. So there is no goal line and no countdown, by rule rather than by omission. The pace public health services describe, about 1 to 2 pounds, or 0.5 to 1 kg, a week, is theirs to describe and yours to read your scale against.
How should I use a scale with a food record?
Over weeks, and beside the record. However you choose to weigh, put the readings next to the week's average intake over recorded days rather than next to one day. Intake steady and weight falling is the deficit you meant; intake steady and weight flat for a month is the moment to reread the record's estimated rows first, then, if it holds up, to talk to someone qualified. IZeat records the intake side; the reading is yours.
What if IZeat records weight one day?
If a weight measurement is recorded one day, it will sit beside the food as a fact, and the same rules will hold for it as for calories: no red, no countdown, no projection, no verdict. What will not be added is a goal line, because a goal line promises a result from a side of the balance the record does not hold. Today the answer is simpler: IZeat records food, and your scale is yours.
