As rates of overweight and obesity continue to rise globally, understanding the nuances of thes conditions is critical for both individual and public health. While Body Mass Index (BMI) remains a key metric – with a BMI of 30 or higher generally indicating obesity [[1]] – experts emphasize that weight management is far more complex than a single number. This article examines the factors contributing to obesity,the importance of addressing stigma,and emerging approaches to comprehensive patient care,highlighting that obesity is a chronic disease requiring ongoing and personalized attention.
Overweight vs. Obesity: Understanding the Difference

The distinction between overweight and obesity hinges on the Body Mass Index (BMI) – calculated by dividing weight by the square of height – but a healthy weight is more complex than a number, experts say. A BMI between 25 and 30 indicates overweight, while a BMI of 30 or higher signifies obesity, according to Professor Martine Laville, Emeritus Professor of Nutrition at Université Lyon 1. However, she emphasizes that a patient’s overall health is the primary concern. “Some individuals already exhibit organ damage even before reaching the obesity threshold according to BMI,” she explains.
The World Health Organization defines obesity as an excessive accumulation of fat, both in quantity and distribution, that negatively impacts health. Professor Laville adds, “We need to look at waist circumference, fat distribution, and clinical signs, not just weight.” This holistic approach is crucial because carrying excess weight can significantly increase the risk of serious health problems, including heart disease, type 2 diabetes, and certain cancers.
A Multifactorial Condition
Obesity is not simply a matter of personal choice, but a complex interplay between genetic predisposition and environmental factors that promote weight gain, according to Professor Laville. Some individuals are born with a genetic vulnerability, while modern lifestyles – characterized by calorie-dense diets, physical inactivity, chronic stress, and sleep disturbances – can accelerate weight gain. “All these factors combine to gradually disrupt metabolism,” she says. Genes can also influence appetite, the enjoyment of food, and how the body utilizes energy, explaining why weight loss isn’t always a matter of willpower.
Addressing Stigma and Misconceptions
A recent survey revealed that 40% of respondents believe obesity is a matter of willpower. This perception contributes to significant stigma, which can prevent individuals from seeking help and hinder open communication with their doctors, Professor Laville points out. However, patients overwhelmingly want their doctors to initiate conversations about weight – with two-thirds hoping their physician will bring up the topic. The survey also found that 75% of general practitioners report proactively discussing weight with their patients, reinforcing their vital role in patient care.
Comprehensive Care Pathways
Effective obesity management requires a comprehensive care pathway, beginning with early intervention when excess fat is present, even before complications arise. “The earlier we intervene, the better we can prevent complications,” explains Professor Laville. This pathway starts with a thorough health assessment to develop a personalized plan that may include dietary modifications, increased physical activity, improved sleep habits, and strategies to combat a sedentary lifestyle. In some cases, medication or surgical interventions may also be considered. Care teams can include general practitioners, specialists, dietitians, psychologists, specialized nurses, and, for severe cases, experts at specialized centers.
Obesity should be recognized as a chronic disease requiring ongoing management. Providing information, fostering open dialogue, and implementing tailored care pathways are essential for preventing complications, improving quality of life, and effectively addressing this significant public health challenge.
