About you
Only used to estimate your needs — never to judge you.
BMI · a rough reference only
BMI is just a reference number — it's not enough on its own to say whether you're healthy.
Calorie formula
Formulas differ by body type; this only changes the math.
You won't get a calorie target — you can set one in Profile.

✓ Database — a reference value per 100 g (Vietnamese Food Composition Table 2007, USDA FoodData Central).
≈ Calculated — from a recipe's ingredients or the closest similar database food.
✨ AI — a rough estimate by AI (Google Gemini) with a likely range: check the amount.
▣ Label — the package label (Open Food Facts, entered by the community).
✎ Yours — numbers you typed.
A total with ≈ includes ≈ or ✨ foods. Tap a food for its amount, serving and source.
Exercise
Recent activities
Walking and running use the ACSM metabolic equations (American College of Sports Medicine, Guidelines for Exercise Testing and Prescription): running VO₂ = 0.2 × speed + 0.9 × speed × incline + 3.5, walking VO₂ = 0.1 × speed + 1.8 × speed × incline + 3.5 (speed in m/min, incline as a fraction), then ≈ 5 kcal per litre of oxygen × your weight. They assume a treadmill (or flat ground outdoors) without holding the handrails; hills, wind and terrain aren't counted. Other activities use MET values × your weight × hours. Every entry keeps the method and numbers it used — history is never silently recalculated. Real burn varies with fitness, technique and body composition.

Why does weight change day to day?
Weight can swing 0.5–1.5 kg within a day or between days with body water, salt, when you last ate or drank, your cycle or activity — normal fluctuation, not necessarily fat gained or lost. Look at the weekly or monthly trend rather than one weigh-in.

What counts as extra activity
Your activity level already includes the workouts you usually do each week, so those don't change your daily target.
When you log a workout as Extra today, DHUT adds an estimate of the energy it used above resting to that day's target, shown with a range because every workout estimate is rough. Choose Part of my usual routine for a regular session. Only the part above resting counts, so not every calorie a watch or machine shows is added, and a workout logged twice counts once.

Delete your health profile and plan history? Your food, weight and exercise logs are not affected. DHUT will ask your health questions again.
Where numbers come from
Databases first. AI estimates are used only when nothing matches, and are always marked ✨.
Imports last until you reload — they aren't saved to your account. The file is a JSON array; each item needs nameVi, nameEn, per100g {energyKcal, proteinG, carbsG, fatG}, source and sourceYear. Missing values stay missing (AI never fills them).
Nutrition & health estimates
Calories and nutrition values are estimates and may vary based on ingredients, serving size and preparation.
Exercise calorie calculations are estimates based on MET values. AI food recognition and health tracking features
are for personal reference and are not a substitute for professional medical or nutritional advice.
