Studies based on neurobiological data and cognitive performance assessments suggest that obesity is also associated with cognitive difficulties. However, the multifaceted and complex nature of the association between obesity and cognitive function makes it difficult to decipher the causal mechanisms of the cognitive difficulties.



Neuroanatomical impairments could lead to increased food consumption, leading to obesity. Obesity-associated biological factors such as insulin resistance and low-grade inflammation could lead to cognitive impairments. Research suggests that metabolic dysfunction, inflammation, or inadequate physical activity could independently impact cognitive function.

Poor sleep quality has strong associations with increased adiposity, greater appetite due to high cortisol and ghrelin and low leptin levels, as well as poor choices about nutritional foods. Impaired sleep has a.
