Disclaimer & Terms of Use
Effective from: October 9, 2026
ℹ️ Important to know
Vita Sustena provides nutritional estimates and general recommendations based on your profile. The app does NOT replace advice from a doctor, nutritionist, or licensed dietitian.
📊 Accuracy of nutritional values
The displayed values (calories, protein, carbohydrates, fats) are ESTIMATES with a margin of error of ±10–15%, depending on:
- Ingredient quality (USDA vs local products)
- Preparation method (water lost during cooking)
- Exact portion size
- Natural variation in foods
💡 Weigh ingredients RAW for the best accuracy. Remember that 100g raw meat ≈ 70g cooked meat (water is lost during boiling/roasting).
🍽️ Recommended quantities
The portions suggested by the app are INDICATIVE. Adapt them to:
- Your hunger and fullness
- Your physical activity that day
- How your body responds (digestion, energy, sleep quality)
- Your schedule (if you eat later or earlier)
⚠️ See a doctor if:
- You have medical conditions (diabetes, hypertension, kidney disease, heart disease)
- You take long-term medication
- You are pregnant or breastfeeding
- You are under 18 (parental consent is recommended)
- You have a history of eating disorders (anorexia, bulimia)
- You want to lose more than 1 kg/week on a sustained basis
- Your BMI is below 18.5 or above 35
⚠️ Allergies and intolerances
Although Vita Sustena tries to exclude allergens based on your profile, ALWAYS check product labels before eating. Manufacturers may change recipes without notice.
🎯 Expected results
Results vary from person to person. Healthy weight loss is 0.5–1 kg/week. If you lose weight too quickly (>1 kg/week on a sustained basis), see a specialist — it may indicate too large a calorie deficit or other problems.
The app does not guarantee specific results. Success depends on:
- Consistency with the nutrition plan
- Physical activity
- Sleep quality and stress management
- Genetic and hormonal factors
📞 Medical emergency
In a medical emergency or if you have unusual symptoms, call 112 immediately or contact your family doctor. Vita Sustena is not an emergency medical service.
