A Qualitative Process Evaluation of Participant Experiences in a Feasibility Randomised Controlled Trial to Reduce Indulgent Foods and Beverages.

There is a growing interest in the effects of ultra-processed/energy-dense nutrient-poor foods on health outcomes, and few interventions to reduce their consumption have been tested. We tested a simple intervention to help people reduce the indulgences they consume (energy-dense nutrient-poor (EDNP) foods). Herein, we report the qualitative findings to understand how participants reduced their consumption by exploring intervention fidelity and the factors affecting consumption. We conducted a qualitative descriptive study of 23 adults who had taken part in a feasibility randomised controlled trial that asked participants to say no to seven indulgences/week and record what they said no to. Data were collected using face-to-face semi-structured interviews and analysed thematically. A total of 23 adults with an average BMI of 30.8 kg/m2 took part. Participants liked the term indulgence, as they could apply it to their normal dietary intake and make small changes. They found self-monitoring what they said no to helpful and reported that emotional eating and habits affected consumption. They had difficulty overcoming these. As most people are consuming too many foods that are EDNP, this simple intervention of "Say No" seven times/week has the potential to be developed as a public health campaign.

Is a small change approach for weight management effective? A systematic review and meta-analysis of randomized controlled trials.

Traditional weight management interventions typically involve people making large changes to their energy intake and/or expenditure and can be effective in the short term, but weight regain is common. An alternative strategy is a small change approach, which asks people to make small(er) changes to their diet and/or physical activity behaviors (e.g., 100-kcal reduction or increases of 1000 steps/day). This approach may lead to sustained weight management because such energy-deficit goals are easier for people to integrate into their lives and then maintain. This systematic review and meta-analysis of randomized and quasi-randomized controlled trials assessed the effectiveness of a small change approach for weight management; 21 trials were included. In weight gain prevention trials with adults, the mean difference in weight change between groups was -0.7 kg (95% CI -1.0 to -0.4, 95% PI -1.1 to -0.3) at program-end and -0.9 kg (95% CI -1.5 to -0.3, 95% PI -3.1 to 1.3) at last follow-up, favoring small change interventions. A small change approach was not effective for weight loss. Only 2/21 trials had a low risk of bias. Initial evidence supports the effectiveness of a small change approach for weight gain prevention but not weight loss. Further high-quality trials with longer follow-up are required.

Metabolic syndrome and weight management programs in primary care: a comparison of three international healthcare systems.

Lifestyle behaviours are contributing to the increasing incidence of chronic disease across all developed countries. Australia, Canada and the UK have had different approaches to the role of primary care in the prevention and management of lifestyle-related diseases. Both obesity and metabolic syndrome have been targeted by programs to reduce individual risk for chronic disease such as type 2 diabetes. Three interventions are described - for either obesity or metabolic syndrome - that have varying levels of involvement of GPs and other primary care professionals. The structure of a healthcare system for example, financing and physical locations of primary care clinicians, shapes the development of primary care interventions. The type of clinicians involved in interventions, whether they work alone or in teams, is influenced by the primary care setting and resource availability. Australian clinicians and policymakers should take into account the healthcare system where interventions are developed when translating interventions to the Australian context.
