French obesity rates are high

Nearly half of the French population is overweight, and 33 % are trying to go on a diet, compared to 45 % of the global population. This highlights the widespread challenge of managing weight in France, where obesity is a growing public health concern.

Weight loss is often temporary

According to data from the U.S. Institutes of Health (NIH) and the American Society for Obesity, 80 to 95 % of individuals who manage to lose weight regain it within three to five years. Scientists suggest this is due to biological factors, not a lack of willpower, such as hormones, genetics, and evolutionary mechanisms that encourage the body to resist weight loss.

Biological factors are key

Kimberley Gudzune, medical director of the American Board of Obesity Medicine, explains that the struggle with weight loss is often misunderstood by popular culture. She emphasizes that the assumption that weight loss is permanent is incorrect, and that researchers are uncovering how hormones, brain chemistry, and childhood experiences influence weight regulation throughout life.

Reality TV highlights challenges

Reality TV shows like The Biggest Loser have brought attention to the difficulty of maintaining weight loss. A 2016 study in the journal Obesity found that participants who lost significant weight during the show regained most of it within six years. Even those who kept the weight off had a slower metabolism, making it harder to maintain the loss.

Metabolic adaptations resist weight loss

Andres Acosta, a gastroenterologist and obesity researcher at the Mayo Clinic, describes these challenges as "metabolic adaptations" that the body uses to resist weight loss. Treatments like bariatric surgery or GLP-1-based medications can help by improving communication between the brain and gut, though some patients have concerns about these methods.

Body weight equilibrium theory

The theory of body weight equilibrium suggests that the body has mechanisms to maintain a certain weight determined early in life, with successive equilibrium points throughout life. While this theory is often referenced, it is not universally accepted by obesity specialists. Kimberley Gudzune notes that while it may oversimplify some processes, it can help the public understand the difficulty of maintaining a healthy weight.

Weight stigma has negative effects

Weight-related stigma affects how people with obesity are treated and can have negative health consequences. Andrew Kraftson, director of the Weight Management Program and Post-Bariatric Endocrinology Clinic at the University of Michigan Health, explains that comparing individuals with weight issues to those with "normal" weight is "faulty reasoning." This stigma can lead to internalized shame and the belief that effective treatments like bariatric surgery or GLP-1 medications are cheating.

Social media influences perceptions

Social media has amplified both the normalization of obesity treatment and the promotion of unrealistic body ideals. A recent Reuters survey found that Instagram regularly promotes content "related to eating disorders" among vulnerable teenagers, though some social media content has helped normalize conversations about obesity treatment.

Weight bias impacts treatment

Kimberley Gudzune notes that the medical field is becoming more aware of weight bias, which she hopes will make treatments more accessible. She highlights that people with obesity can experience internalized weight bias, leading to health issues such as body image disorders, depression, and eating disorders.

Personalized treatment approaches

Andres Acosta uses a clinical phenotyping test to classify patients into four groups based on their weight loss challenges: "hungry brain," "hungry gut," "emotional hunger," and "slow metabolism." This allows for personalized treatment and medications targeting the underlying mechanisms of obesity, potentially leading to long-term success in both weight loss and maintenance.

Obesity is a chronic condition

Kimberley Gudzune stresses that obesity should be treated by health professionals, just as other chronic conditions like hypertension or diabetes are. Andrew Kraftson emphasizes that comprehensive care, including dietitians and mental health professionals, is essential for managing obesity, which is a complex and chronic disease influenced by biology, environment, and mental health.
