Evaluation of the experience of people referred under the NHS enhanced service incentive for obesity to the NHS digital weight management programme
Background Internationally, guidelines recommend clinicians identify patients living with obesity and offer referral to weight management programmes, especially patients with related co-morbidities. In 2021, NHS England introduced the NHS Digital Weight Management Programme for people living with obesity and a diagnosis of hypertension or diabetes or both. The programme is offered at three levels of intensity with people triaged to the appropriat…

Identifying Key Moments in Type 2 Diabetes Management
OBJECTIVE: For people with type 2 diabetes who are overweight, weight loss increases the likelihood of achieving diabetes remission. The aim here was to draw on the experiences of people living with type 2 diabetes and coaches who deliver type 2 diabetes prevention and remission programmes. This was done to develop a service that increases the proportion of people who achieve remission by identifying an effective weight management service. RESEAR…
Do promotions of healthier or more sustainable foods increase sales? Findings from three natural experiments in UK supermarkets
During promotional campaigns there was evidence that sales of plant-based products increased, but not seasonal fruits. There was no evidence for any sustained change beyond the intervention period
Testing the effect of a dynamic descriptive social norm message on meat-free food selection in worksite cafeterias
Changing the availability and positioning of more vs. less environmentally sustainable products
Food purchasing behaviours are shaped by the choices available to shoppers and the way they are offered for sale. This study tested whether prominent positioning of more sustainable food items online and increasing their relative availability might reduce the environmental impact of foods selected in a 2x2 (availability x position) factorial randomised controlled trial. Participants (n = 1179) selected items in a shopping task in an experimental …
Ethnic differences in meat consumption attitudes, norms and behaviors
A reduction in meat consumption is necessary to mitigate negative impacts of climate change and adverse health outcomes. The UK has an increasingly multi-ethnic population, yet there is little research on meat consumption habits and attitudes among ethnic groups in the UK. We ran a survey (N = 1014) with quota samples for ethnic groups and analyzed attitudes, behaviors and norm perceptions of White, South Asian and Black British respondents. Most…
The development of a method for the global health community to assess the proportion of food and beverage companies’ sales that are derived from unhealthy foods
CONTEXT: Corporate engagement with food and beverage companies who produce food associated with health harms is a divisive topic in the global nutrition community, with high-profile cases of conflict of interest increasingly coming under scrutiny. There is a need for an agreed method to support health organizations in deciding whether and how to engage with large food and beverage manufacturers. AIM: The aim of this study was to develop a method …

Nutrition labels and ecolabels can support consumers to make healthier and more sustainable choices, and the former is now widespread. But there is no information on the impact of ecolabels in the presence of nutrition labels. The aims of this study were primarily to examine whether (1) ecolabels are effective at promoting sustainable purchasing behaviour if presented alongside nutrition labels; (2) and secondarily, whether nutrition labels are e…
The impact of price promotions on confectionery and snacks on the energy content of shopping baskets
Overconsumption of foods high in fat, sugars, and salt (HFSS) poses a significant risk to health. The government in England has passed legislation that would limit some price promotions of HFSS foods within supermarkets, but evidence regarding likely impacts of these policies, especially in online settings, is limited. This study aimed to determine whether there were any differences in the energy and nutrient content of shopping baskets after rem…
A dynamic social norm messaging intervention to reduce meat consumption
Perceptions of social norms around eating behavior can influence food choices. Communicating information about how others are changing their eating behavior over time (dynamic descriptive social norms) may motivate individuals to change their own food selection and consumption. Following a four-week baseline period, 22 in-store restaurants of a major retail chain across the UK were randomized to display a dynamic descriptive social norm message i…
Testing the effectiveness of ecolabels to reduce the environmental impact of food purchases in worksite cafeterias
1. Introduction Meeting global climate targets will require a marked reduction in environmental impacts caused by dietary patterns (Willett et al., 2019), with several UK supermarkets setting targets to halve the environmental impact of customers' food shopping by 2030 (Lee, 2021). The environmental impacts of different types of foods are highly variable, and variation in impact is also seen for a given food. For example, there is a 50-fold varia…

The Effects of Environmental Sustainability Labels on Selection, Purchase, and Consumption of Food and Drink Products
This review assessed the effects of environmental labels on consumers’ demand for more sustainable food products. Six electronic databases were searched for experimental studies of ecolabels and food choices. We followed standard Cochrane methods and results were synthesized using vote counting. Fifty-six studies ( N = 42,768 participants, 76 interventions) were included. Outcomes comprised selection ( n = 14), purchase ( n = 40) and consumption …
Experiences of Self-Monitoring in Self-Directed Weight Loss and Weight Loss Maintenance
The experience and role of self-monitoring in self-directed weight loss attempts may be distinctly different from that within formal interventions, and has yet to be fully explored. We systematically reviewed qualitative studies to examine experiences of self-monitoring as an aid to self-directed weight loss. Thematic synthesis was used to construct descriptive and analytical themes from the available data. In all, 22 studies (681 participants) w…
Two observational studies examining the effect of a social norm and a health message on the purchase of vegetables in student canteen settings
There is some evidence from laboratory-based studies that descriptive social-norm messages are associated with increased consumption of vegetables, but evidence of their effectiveness in real-world settings is limited. In two observational field studies taking an ecological approach, a vegetable-related social norm (e.g. "Did you know that most students here choose to eat vegetables with their meal?"), and a health message (e.g. "Did you know tha…
Impact of increasing the proportion of healthier foods available on energy purchased in worksite cafeterias
Increasing the proportion of healthier foods available could encourage healthier consumption, but evidence to date is limited in scope and quality. The current study aimed to: (a) examine the feasibility and acceptability of intervening to change product availability in worksite cafeterias; and (b) estimate the impact on energy purchased of increasing the proportion of healthier (i.e. lower energy) cooked meals, snacks, cold drinks and sandwiches…
Optimising swaps to reduce the salt content of food purchases in a virtual online supermarket
BACKGROUND: Offering consumers the opportunity to swap to lower-salt foods while shopping has potential to reduce salt intake. Offering a wider range of alternatives which are much lower in salt could increase the magnitude of salt reduction gained but may interfere with consumers' engagement and willingness to accept swaps. OBJECTIVES: To compare the salt reduction from offering swaps to a similar product but with minimally less salt to offering…
What is the impact of increasing the prominence of calorie labelling? A stepped wedge randomised controlled pilot trial in worksite cafeterias
BACKGROUND: Calorie labelling may help to reduce energy consumption, but few well-controlled experimental studies have been conducted in real world settings. In a previous randomised controlled pilot trial we did not observe an effect of calorie labelling on energy purchased in worksite cafeterias. In the present study we sought to enhance the effect by making the labels more prominent, and to address the operational challenges reported previousl…
Meat consumption, health, and the environment
The future of meat Meat consumption is rising annually as human populations grow and affluence increases. Godfray et al. review this trend, which has major negative consequences for land and water use and environmental change. Although meat is a concentrated source of nutrients for low-income families, it also enhances the risks of chronic ill health, such as from colorectal cancer and cardiovascular disease. Changing meat consumption habits is a…
Grocery store interventions to change food purchasing behaviors
Perceived impact of smaller compared with larger-sized bottles of sugar-sweetened beverages on consumption
Sugar-sweetened beverage (SSB) consumption increases obesity risk and is linked to adverse health consequences. Large packages increase food consumption, but most evidence comes from studies comparing larger with standard packages, resulting in uncertainty regarding the impact of smaller packages. There is also little research on beverages. This qualitative study explores the experiences of consuming cola from smaller compared with larger bottles…

Estimating food portions. Influence of unit number, meal type and energy density
Estimating how much is appropriate to consume can be difficult, especially for foods presented in multiple units, those with ambiguous energy content and for snacks. This study tested the hypothesis that the number of units (single vs. multi-unit), meal type and food energy density disrupts accurate estimates of portion size. Thirty-two healthy weight men and women attended the laboratory on 3 separate occasions to assess the number of portions c…

Effect of increasing the price of sugar-sweetened beverages on alcoholic beverage purchases
BACKGROUND: Taxing soft-drinks may reduce their purchase, but assessing the impact on health demands wider consideration on alternative beverage choices. Effects on alcoholic drinks are of particular concern, as many contain similar or greater amounts of sugar than soft-drinks and have additional health harms. Changes in consumption of alcoholic drinks may reinforce or negate the intended effect of price changes for soft-drinks. METHODS: A partia…

Obesity in Britain
The prevalence of clinical obesity in Britain has doubled in the past decade. The Health of the Nation initiative has set ambitious targets for reversing the trend in recognition of the serious health burden which will accrue, but efforts to develop prevention and treatment strategies are handicapped by uncertainty as to the aetiology of the problem. It is generally assumed that ready access to highly palatable foods induces excess consumption an…
Healthy percentage body fat ranges
Beyond body mass index
Body mass index (BMI) is the cornerstone of the current classification system for obesity and its advantages are widely exploited across disciplines ranging from international surveillance to individual patient assessment. However, like all anthropometric measurements, it is only a surrogate measure of body fatness. Obesity is defined as an excess accumulation of body fat, and it is the amount of this excess fat that correlates with ill‐health. W…
Fast foods, energy density and obesity
Fast foods are frequently linked to the epidemic of obesity, but there has been very little scientific appraisal of a possible causal role. Here we review a series of studies demonstrating that the energy density of foods is a key determinant of energy intake. These studies show that humans have a weak innate ability to recognise foods with a high energy density and to appropriately down‐regulate the bulk of food eaten in order to maintain energy…
Consumption of whole-grain foods by British adults
Objective: To assess the consumption of whole-grain foods in different age and sociodemographic groups in Great Britain, using data from two national surveys. Design: Cross-sectional analysis of the consumption of whole-grain foods.

Appetite control
This report describes a set of scientific procedures used to assess the impact of foods and food ingredients on the expression of appetite (psychological and behavioural). An overarching priority has been to enable potential evaluators of health claims about foods to identify justified claims and to exclude claims that are not supported by scientific evidence for the effect cited. This priority follows precisely from the principles set down in th…
