A new study looks at the effect of the Health at Every Size (HAES) diet approach.

Known for its focus on intuitive eating rather than body weight modification, HAES emerged over a decade ago as a response to the stigma and discrimination encountered by individuals with larger bodies. 

The study by the University of Newcastle and Hunter Medical Research Institute found no substantial improvements in cardiometabolic health indicators, depression, restrictive eating behaviours, or weight outcomes through HAES-based interventions.

Laureate Professor Clare Collins from the University of Newcastle says that while HAES plays a significant role in cultivating a healthier food relationship, especially concerning hunger management, it falls short in addressing medical aspects of weight-related health issues. 

She says there is still a need for medical nutrition therapy in treating diet-related chronic health conditions such as high blood pressure and elevated blood fats.

With obesity prevalence climbing globally, the discourse around effective dietary health improvement strategies intensifies. 

The HAES approach, which advocates for a shift from weight reduction to health and size acceptance, encourages eating based on internal hunger or satiety cues and engaging in moderate physical activity. 

Experts say the enthusiasm surrounding HAES as an alternative obesity treatment option should not outshine intervention strategies that are conducive to optimising weight-related health, especially considering the emergence of effective medical treatments including medication and bariatric surgery. 

The review acknowledges the positive trends HAES indicates towards body image, well-being, and eating behaviour, albeit without extending these benefits to other health domains.
