One day, as IQFood estimates it

Your metabolism has a plot.
IQFood lets you read it.

00:00

07:40 · Breakfast, logged in secondsPhoto, voice or barcode. The estimate updates right away: a gentle rise.

13:10 · A bigger rise aheadWhite bread and a soda: IQFood estimates a larger glucose rise, and fat burning dipping while insulin is high.

17:30 · Small move, visible payoffA short walk after eating helps muscles take up glucose; IQFood shows the estimated effect.

22:00 · Fat burning rises againDinner digested and insulin settling, estimated fat burning rises again overnight.

Not just calories.
Consequences.

Calories are the receipt. IQFood estimates the transaction: what each meal is likely to do to your fuel use, your hunger and your day.

Key screens

Four screens at the heart of IQFood

The estimated curves

Glucose, insulin, ketones and cravings, estimated from today's log, with the next hours projected.

Fasting, made visible

A fuel-use estimate, not a countdown: when digestion is likely to finish and fat burning to ramp up. Fasting is not suitable for everyone.

Your cycle, same graph

Typical estrogen and progesterone patterns next to your metabolism estimates. Illustrative, not measured.

Trends that mean something

Weight forecast, weekly patterns, and insights that forecast outcomes instead of nagging.

In the app

Designed around your day

Log in seconds

Snap a photo, hold to speak, or scan a barcode across 4.6 million products. AI does the tedious part.

An engine that learns from you

Personalized from your logs, sleep and check-ins. On Android, add a blood test and the estimates take it into account.

Hours ahead

The dotted line is an estimate of the next few hours, so you can think about dinner before you eat it.

Bring your people

Friends, streaks and stories. Or connect your trainer and choose what they can see.

Private by default

Your health data runs the app for you. It is never sold and never becomes an ad profile. Delete it any time in the app, or ask us for a copy.

Weight, forecast

An estimated date for your goal, based on your recent weight trend and what you log, and adjusting as your weight changes. Not a generic 500-kcal rule.

Our approach

Built on published research. Clear about its limits.

Labeled as estimates

Curves are estimates computed from your logs, without false precision. In the app, the curves explain what drives them and how sure the estimate is.

Grounded in research

Glycemic response, ketosis, fat adaptation, cortisol and sleep, built from published research and adjusted using what you log. See the sources.

Not a medical device

IQFood informs; it does not diagnose. If you have a medical condition, talk to a doctor or dietitian before changing how you eat.

The Metabolism Journal

Learn the plot of your own body

Short, sourced reads on the science behind the engine, written to be understood.

Glucose

Can an app show how food affects blood sugar without a sensor?

What a model-based estimate can and cannot tell you about blood sugar after a meal, how it compares with a continuous glucose monitor, and what drives the rise.

Tracking

How accurate is calorie counting? Labels, databases and photo estimates

Every way of counting calories has error: label tolerances, database gaps, portion guesses and AI photo estimates. What the research shows, and why consistent logging is still useful.

Weight

Why your weight changes from day to day, and how to read the trend

Most day-to-day changes on the scale are water and the food still in your gut, not body fat. What moves the number, how big the swings tend to be, and how to read the trend underneath.
