Obesity is a complex chronic medical condition driven by biological signals and genetics rather than a simple lack of willpower, according to experts at Santé Québec – Institut universitaire de cardiologie et de pneumologie de Québec – Université Laval who are preparing for the upcoming Denis Richard Symposium.
Shift Patient Goals Toward Sustainable Lifestyle Improvements
- Biological Hunger: Hunger functions as a biological drive akin to thirst, meaning individuals cannot simply choose to stop feeling it.
- Genetic Influence: Multiple genes dictate weight gain, energy maintenance, and food preferences beyond conscious behavioral control.
- Quality of Life Focus: Clinical dieticians recommend shifting patient goals from weight loss on a scale to sustainable lifestyle improvements and long-term health.
Biological Drivers Replace Willpower in Clinical Understanding
When society thinks of obesity, the excessive accumulation of body fat, people often blame an individual who lacks the willpower and discipline to eat well and exercise. Researchers at the Institut universitaire de cardiologie et de pneumologie de Québec – Université Laval (IUCPQ-UL) state that the science reveals a much more complex story. Marianne Legault, a dietician with IUCPQ-ULaval, told CTV News that the biggest myth involves believing that moving more and eating less will eradicate obesity and weight problems.
Legault explained that multiple physiological responses occur in the body when an individual attempts to lose weight. Multiple genes affect how a person gains or maintains weight. Legault noted that brain chemistry determines food preferences beyond conscious control. Dr. Alexandre Caron, a researcher at IUCPQ-ULaval, told CTV News that hunger operates as a biological signal just like thirst. People do not decide how hungry they feel any more than they choose how thirsty they are. Caron offered the example of someone missing lunch, noting that food starts taking up more space in conversations and while a person can wait before eating, they cannot decide to stop feeling hungry.
Prioritize Treatments for Patients with Metabolic Risks
Caron noted that obesity has long been considered an epidemic, adding that it is encouraging to see new drugs approved to tackle the issue. Society has made the decision that everyone can take these medications quite easily, but Caron argued that treatments should benefit the people who need them the most. Those individuals include patients living with obesity associated with metabolic risks such as hypertension or diabetes.
Caron evaluates numerous reasons why a person puts on weight during his years of studying the disease. Some individuals live with obesity due to malfunctioning hunger signals, larger appetites, or emotional factors driving food intake. Mental health also plays a major role in how patients process nutrition. Understanding this complex biology helps researchers predict why someone lives with obesity and allows clinicians to help patients more effectively.
| Biological Factor | Primary Mechanism | Clinical Impact |
|---|---|---|
| Hunger Signaling | Hypothalamic drive comparable to thirst | Regulates baseline appetite and food preoccupation |
| Genetic Predisposition | Multi-gene variants affecting energy homeostasis | Determines individual weight gain susceptibility |
| Metabolic Comorbidities | Insulin resistance, vascular strain | Drives clinical priority for pharmacological intervention |
Shifting Treatment Toward Sustainable Quality of Life
For Legault, addressing obesity requires shifting focus away from losing weight and toward getting healthy. Setting realistic goals changes the clinical objective toward smart outcomes. Small steps lead to greater behavioral changes that patients can sustain over time. Legault suggested that committing to eating dessert two or three times a week rather than every day represents a realistic alternative to strict bans on favorite foods.
Overcoming the urge to prioritize the physical benefits of weight loss remains difficult for many patients. Legault emphasized that people often view the number on the scale as the primary aim, whereas clinical science shows that the real goal involves achieving a better quality of life, moving easily with children or grandchildren, and growing old with a healthy body.
Persistent Prevalence and Upcoming Symposium Discussions
Despite years of research, medical advancements, and new therapies, Caron pointed out that obesity numbers continue to rise. The prevalence of obesity has been going up and up without any hint of improvement. While medicine excels at helping people lose weight, current therapies remain less effective at keeping patients in that state. Researchers aim to distance public conversations from blame and judgment, treating obesity as a complex disease while addressing social stigma.
Experts Feature Obesity Science at Upcoming Symposium
Conversations regarding the science, clinical realities, and treatment advances for obesity will feature prominently at the 2026 Denis Richard Symposium on Nov. 10 in Quebec City. Experts plan to bring together science, clinical expertise, and lived experience in a format designed to make these issues accessible to the public.
