Understanding the effect of social norms and environmental messaging on influencing acceptance of cultivated meat in the UK
Open AccessHarmehak Singh, Gregory S Keenan et al.ARTICLEAppetite2026References: 47
Cultivated meat represents an emerging approach to food production, yet its consumer adoption remains uncertain. Using an experimental mixed design, this study examined the impact of different informational messages on five indicators of cultivated meat acceptance in the UK (trying, wanting, liking, buying and incorporating into diet). A total of 346 participants (M = 25.6 years, 65% female) were randomly assigned to one of four conditions: Gener…
Concern About Covid ‐19 Mediates the Relationship Between Life‐History Strategy and Stockpiling Food
Open AccessAlyson Blanchard, Gregory S Keenan et al.ARTICLEInternational Journal of Psychology2025
Life‐history theory (LHT) charts the relationship of environmental conditions to resource allocation trade‐offs made by organisms to either reproduce or invest in somatic maintenance. Hazardous environments in which resources are unreliable should prompt adoption of a “fast” life‐history strategy in which short‐term gains are favoured. The COVID‐19 pandemic presents an opportunity to examine whether an increase in existential threat as signalled …

Understanding the association between household food insecurity and diet quality
Open AccessRebecca Evans, Paul Christiansen et al.ARTICLEAppetite2025Cited by: 1References: 42
Household food insecurity - a lack of reliable access to food that is safe, nutritious, and sufficient for normal growth - is associated with physical and mental ill-health. In the UK and many countries worldwide, food insecurity has been exacerbated by the cost-of-living crisis and is a major public health concern. To identify potential points of intervention, it is important to understand how food insecurity is associated with individual-level …
Investigating the mediating role of physical activity within the association between food insecurity and BMI
Open AccessThomas Gough, Oli Brown et al.ARTICLEAppetite2025Cited by: 1References: 31
Food insecurity is linked with obesity and while the mechanisms behind this association are complex, lower levels of leisure-time physical activity in those with food insecurity may contribute to this. Individual-level factors (such as concerns of performing physical activity) may partly determine levels of physical activity within individuals with food insecurity, as such individuals may seek to minimise their levels of physical activity in orde…
The development and validation of the food insecurity physical activity concerns scale
Open AccessThomas Gough, Paul Christiansen et al.ARTICLEAppetite2024Cited by: 2References: 29
Food insecurity - defined as having limited access to nutritious foods - is linked with obesity. Previous research has also shown that food insecurity is associated with lower levels of leisure-time physical activity (physical activity performed outside of essential activities). This association may occur in part due to concerns about preserving levels of energy during times of food shortage. Currently, no scale exists which measures this constru…
The association between Covid-19 related income loss and diet quality
Open AccessGregory S Keenan, William S Royle et al.ARTICLEAppetite2024References: 28
The COVID-19 lockdowns saw many individuals lose income, experience distress and increase intake of foods that would typically be considered less 'healthy' (more processed and less fresh produce). Establishing whether there are direct and indirect links between these variables would be of benefit in preparing for similar future events but also has implications for the current global financial climate, where many are experiencing relative decrease…

Effects of meal variety on expected satiation
Open AccessGregory S Keenan, Jeffrey M Brunstrom et al.ARTICLEAppetite2015Cited by: 9References: 43
Meal variety has been shown to increase energy intake in humans by an average of 29%. Historically, research exploring the mechanism underlying this effect has focused on physiological and psychological processes that terminate a meal (e.g., sensory-specific satiety). We sought to explore whether meal variety stimulates intake by influencing pre-meal planning. We know that individuals use prior experience with a food to estimate the extent to whi…
