The Nutritional Management of Obesity (#145)

The clinical management of obesity is strongly focussed on weight loss. This approach has been underpinned by translation of epidemiological studies relating to health risks of obesity. However, considerable data have clearly shown that weight lost by intentional caloric restriction is extremely difficult to maintain and weight cycling is more deleterious than maintaining a constant weight.  

This presentation will explore (i) sustainable dietary strategies aimed at optimisation of metabolic and overall health and wellbeing emphasizing their alignment with a whole foods approach, and (ii) the contrasting detrimental effects of ultra-processed foods.

Whole foods — rich in dietary fibre, essential nutrients, and bioactive compounds contribute to gut microbiota modulation, satiety hormone regulation, and inflammation reduction, promoting weight stability and overall health and well-being.

The emerging concept of chrono-nutrition will be addressed including the effects of circadian rhythms, meal timing, on metabolic pathways and obesity outcomes, and efficacy and sustainability of intermittent time restricted eating.  

Obesity and associated chronic disorders and the affected individuals represent considerable genetic and phenotypic heterogeneity, strongly influenced by environmental and sociodemographic factors. Personalised strategies to management require integration of nutrition and physical activity with pharmacotherapy, metabolic surgery, behavioural and psychosocial approaches. Advocacy for a supportive environment and avoidance of stigma are essential elements for successful long-term outcomes
