Scientific research and evidence-based guidelines that power Thrive AI's personalized health recommendations
Thrive AI is an app that helps users manage their weight through diet management and lifestyle improvement. We support tracking food calories and water intake, and provide users with personalized diet recommendations.
Our core features include calorie tracking, macronutrient tracking, water intake tracking, and weight tracking. The key to weight management is adjusting dietary habits and lifestyle. We encourage healthy eating and proper calorie intake adjustments to help users achieve their weight management goals.
Please note: While Thrive AI helps users understand calories, nutrition, and hydration habits, it is not a medical device or medical app and is not intended for diagnosis, advice, prevention, or treatment of any disease or medical condition. Always consult a doctor or healthcare professional for medical advice and treatment before making any medical decisions.
Body Mass Index (BMI) is a calculated measure of weight relative to height. For adults, BMI is categorized into underweight, healthy weight, overweight, and obesity.
BMI Formula:
BMI = weight (kg) / height (m)²
| BMI Category | BMI Range |
|---|---|
| Underweight | Less than 18.5 |
| Healthy Weight | 18.5 to less than 25 |
| Overweight | 25 to less than 30 |
| Obesity | 30 or greater |

The calorie recommendation is derived from the Mifflin-St Jeor Equations, which estimates the user's Basal Metabolic Rate (BMR) (see the calculation below). Based on the BMR, physical activity level, and personal goals, we suggest a tailored daily calorie intake.
For men:
BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (y) + 5
For women:
BMR = 10 × weight (kg) + 6.25 × height (cm) - 5 × age (y) - 161
The pace of weight gain or loss should be tailored to your personal energy needs. For safe and sustainable results, we suggest a gradual process, with no more than 1 kg (2.2 lb) lost or gained each week.

Physical activity plays a crucial role in determining your total daily energy expenditure. We calculate your recommended calorie intake by factoring in your activity level along with your BMR.
