The system for maintaining a healthy body weight, human or animal, is weight management. While it monitors subjects in real time, it also relies on both established and new scientific data as guidelines for activity and nutrition.
Proper weight maintenance improves physical and mental well-being as well as prevents future illness or injury.
To build a proper weight maintenance system, begin with individual age, sex, activity level, and current and desired weight. Additional vital data includes medical conditions, allergies, and religious or other convictions that restrict diet.
External data necessary for weight maintenance are nutrition data and, if relevant, data on medications taken—especially their interactions with food or side effects. Some medications, for example, cause sleep disturbances which make weight management very difficult.
Organizational psychology data may also help a weight management system, especially if this system is part of a workplace health and wellness plan; such psychological data can help provide motivation for employees participating in these programs.
Budget or other financial data may also be included in a this type of system.
There are several challenges of this use case. Some environments, for example, lack enough food or simply enough nutritious food; social obligations pressure individuals to overeat or under-eat; underlying health issues may interfere with the ability to follow a diet or exercise program at all.
There are also enormous amounts of nutrition data that is seemingly inconsistent or contradictory. Additionally, social trends often outpace the science. For example, the benefits of fasting or eating multiple meals, eating a low-carb, high-fat diet vs a low-fat, high-carb diet, or whether eggs are healthy at all. Sport or exercise data, especially as it relates to age or sex, suffers from similar inconsistent data or incorrect information.

The indicator measures the share of obese people based on their body mass index (BMI). BMI is defined as the weight in kilos divided by the square of the height in meters. People aged 18 years or over are considered obese with a BMI equal or greater than 30. Other categories are: underweight (BMI less than 18.5), normal weight (BMI between 18.5 and less than 25), and pre-obese (BMI between 25 and less than 30). The category overweight (BMI equal or greater than 25) combines the two categories pre-obese and obese.
