What you can do
Progress, weight and fasting, in detail
Progress photos and comparison
Upload photos, compare two moments side by side and note body measurements. Free and no coins.
Estimated body fat
An estimate using the U.S. Navy method with category, fat mass and lean mass from your measurements and your latest weight. If a piece of data is missing, it tells you which.
Adaptive TDEE
With your trend weight and the intake logged over the last few weeks, DietaGo calculates your real expenditure and blends it with the theoretical one while there's little data. No AI, deterministic.
Automatic weekly adjustment
If you turn it on, the goal is recalculated each week only when confidence is high enough and the change exceeds 50 kcal. It notifies you and you can undo it for 7 days.
Safeguards
No deficit for under-18s or with a low BMI, deficit capped at a percentage of expenditure and minimum calorie floors. The goal is rounded and keeps your macro proportions.
Intermittent fasting
Protocols such as 16:8, 18:6 or 5:2, a timer with live stages, history by month and, on the reduced-intake days of 5:2 and 6:1, the day's goal drops on its own.
Log a past fast
Didn't hit the timer? Tell us when you started and when you finished, and it's added to your history as if you had timed it.
Live Activity on iOS
Your fast and the day's summary show on the lock screen and in the Dynamic Island, updated from the server even when the app is closed. On Android, a persistent notification with a timer.
How it works
In three steps
1
Log weight and meals
The more regular you are, the sooner the adaptive TDEE will have enough data. Frequent weigh-ins and an up-to-date diary are enough.
2
Turn on the weekly adjustment
In Progress, switch on the automatic adjustment. Each week the app reviews the trend and, if needed, moves the goal by a few dozen calories.
3
Follow your habits
Fasting, water, sleep, steps and mood show on Home, in the calendar and, on iPhone, on the lock screen.

Frequently asked questions
Questions about progress, weight and fasting
What is the adaptive TDEE?
It's an estimate of your real energy expenditure calculated from your trend weight and the intake you've logged over the last few weeks, rather than just a theoretical formula. It's deterministic, uses no AI and is free. It's blended with the theoretical TDEE while there's little data.
Does the app change my goal without telling me?
No. The weekly adjustment is optional; if you turn it on, it's only applied when the calculation's confidence is medium or high and the difference exceeds 50 kcal, it notifies you and you can undo it during the following 7 days.
How does intermittent fasting work?
You choose a protocol (16:8, 18:6, 5:2...), tap start and the app shows you the stage you're in, the hours elapsed, the hours remaining and the percentage completed. You can finish or cancel whenever you like and review the history by month. The 5:2 and 6:1 protocols lower the goal on the marked days.
Can I log a fast I didn't time?
Yes. In “Log a past fast” you choose the protocol, when you started and when you finished, and the app calculates the duration and adds it to your history. You can also do it from an empty day in the calendar.
What is the fasting Live Activity on iOS?
On an iPhone with iOS 16.1 or later, your fast appears on the lock screen and in the Dynamic Island and changes stage via push notification even when the app is closed. There is also a Live Activity for the day with calories, habits and streak.
Does DietaGo replace a professional?
No. DietaGo is a tracking tool and doesn't replace the advice of a healthcare professional. If you have a medical condition, consult your doctor or a registered dietitian.
