Reports, forecasting and getting your data out

A report built for the ten minutes you get with a clinician, exports in three real formats, and a forecast that decelerates the way weight loss actually does. All of it from the data you already logged, none of it invented.

A Loopa report on iPhone, summarizing the last 90 days
What a report contains

Thirty days, on one page you can hand to a clinician.

Food, weight, water, vitals and activity over the same window, with the numbers a doctor asks for already lined up. Export it as PDF or CSV; nothing is summarized away.

A report for a real appointment

Pick 30, 60 or 90 days, 6 months or a year. You get latest vitals against normal ranges, eleven charted metrics with the normal band shaded, the trends worth discussing, your goals, and your health context. Open it, print it, or save it as PDF.

It is never stored on our server

The report is built while you ask for it and streamed straight to you. There is no copy sitting in a bucket waiting to be found.

Three export formats

CSV, a real Office Open XML spreadsheet, and a one-page PNG chart sheet. Nineteen columns a day covering weight, body fat, macros, water, blood pressure, resting heart rate, glucose, SpO2, temperature, INR, sleep and mood.

A forecast with physics in it

As you lose weight your BMR falls, so the same intake produces slower loss. Loopa recomputes that every week instead of drawing a straight line, and shows a confidence band around the result.

Calibrated to you, within reason

Your measured last 30 days adjust the model, clamped at 500 calories a day either way. That cap is an engineering guardrail rather than a physiological boundary: measured expenditure after substantial weight loss has been observed to run several hundred calories a day below prediction. Fothergill and colleagues measured −499 ± 207 kcal/day six years on in Obesity (2016), and beyond that range a correction is far more likely to be a badly logged month than a metabolism.

It refuses to promise

If the intake never reaches the goal it says so rather than picking a date. It stops at 52 weeks because past that the band swallows the line. And it will not project below 1,500 calories for men or 1,200 for women at any pace you ask for, the bottom of the range the 2013 AHA/ACC/TOS guideline on managing overweight and obesity prescribes for weight loss.

Common questions

Is the report a PDF?

It is a self-contained HTML file you open and then print or save as PDF, which is what the browser does better than we would. That also means it opens on anything, including a clinic computer that will not install software.

What does the forecast actually predict?

A week-by-week weight projection to your goal, with a plus or minus 20% band, and your real weigh-ins from the last 84 days drawn on the same axis so you can see whether it has been right so far.

Why will it not show me a faster date?

Because below 1500 calories for men or 1200 for women it stops and says the pace is not sustainable, rather than drawing the line you asked for. A forecast that will show you anything is not a forecast.

Can I get all my data out?

Yes. CSV, XLSX and a full account export. Every export is logged in your own read trail so you can see when it happened.
