Why Anlo tracks food in 14-day periods

Updated 2026-10-10

Short answer: Anlo works in 14-day periods. You log as usual; at the end, Anlo shows your intake against your target day by day, your averages and how your weight moved, and an AI summary that separates what it observed from what it thinks. It suggests what to try in the next 14 days, so each period can test one change.

Why two weeks

Fourteen days is Anlo's design choice, and here's the reasoning behind it.

A large study of people logging meals in an AI-assisted app found that 3 to 4 days, including at least one weekend day, were enough to estimate most nutrients reliably; carbohydrates, protein and fat needed only 2 to 3 days. It also found clear weekend effects, with more energy, carbohydrates and alcohol on weekends. (Singh, Verest & Salathé, European Journal of Clinical Nutrition, 2025; 958 adults in Switzerland, self-reported data.)

That study doesn't say 14 days is needed or optimal. What it supports is that a two-week period comfortably covers the few days needed for a stable picture and includes two full weekends, so a weekday-heavy week or one big Saturday doesn't decide the result. That makes one period a fair thing to compare with the next.

Days 1 to 14: just log

Don't change anything at first. Log meals the quickest way you can, by photo, voice or a sentence, along with water, activity, weight and any labs or medications you track. Today shows where you are in the period ("Day 6 of 14").

Day 14: look back

When the period ends, the review shows:

• Intake vs target for each day, and how many days were logged;
• Averages for intake, protein and water, and the weight change across the period;
• an optional AI summary: a one-line headline, what it observed (numbers and dates), how it interprets that (hedged), how you did on each of your goals, and what to try next.

Observed and interpretation are kept apart on purpose. Anlo points out patterns without claiming one thing caused another.

The next 14 days: one change

Pick one suggestion and make it the experiment for the next period. One change at a time is how you can tell what helped. Then the next review shows whether the numbers moved.

An example (illustrative, not a real user): over a period, protein averaged 78 g against a 95–125 g target, with the gap mostly at breakfast. The suggestion: about 30 g of protein at breakfast for the next 14 days, then compare.

Ideas for small experiments

Keep them small, specific and food-related:

• about 30 g of protein at breakfast;
• keeping up with your water pace through the afternoon;
• a short walk after lunch;
• swapping one sugary drink a day for water or tea.

Avoid changing several things at once, and talk to a professional before changing anything related to a medical condition or medication.

The coach in between

You don't have to wait for day 14. Ask the coach a question, like "how's my protein this week?", and it answers from your recent log the same way: what it observed, what it thinks, and one thing to try.
