Is there a role for higher cognitive processes in the development of obesity in humans?

Cognition plays a crucial role in human eating behavior, influencing its flexibility. Disruptions in higher cognitive functions, such as inhibitory control and memory, can lead to increased food intake, potentially contributing to weight gain over time. This review by Higgs (2023) aims to summarize the current evidence on cognition as a potential causal factor in human obesity development. Meta-analytic evidence indicates that cognitive function is cross-sectionally associated with obesity, even after controlling for various confounders. However, reverse causality might also explain this association, as evidence suggests that metabolic syndrome and prolonged consumption of an unhealthy Western diet can affect brain structure and cognitive abilities. Longitudinal, interventional studies and animal models support the idea of a reciprocal relationship between obesity and cognitive function. Despite this, it remains unclear whether disruptions in cognitive processes are a primary cause of obesity in humans. [NPID: Eating, cognition, causes of obesity, memory, inhibitory control]

Markers of a plant-based diet relate to memory and executive function in older adults

Despite published evidence pointing to the health benefits of a plant-based diet, the level of evidence investigating the links between cognitive health and plant-based food remains insufficient. Recent publications postulate the impact of certain macronutrients on overall cognition, however, the mechanisms behind the interaction between plant-based foods and cognitive domains are not clear. In this […]
