Data from the 2015 Health Survey for England (HSE) shows that between 1993 and 2015, obesity in men rose from 13·2 % to 27·0 %, and the proportion of men with a healthy weight BMI decreased from 41 % to 30 %( Reference Moody and Neave 1 ). The development of overweight and obesity is associated with food and exercise behaviours( Reference Shaw, Gennat and O'Rourke 2 ). Social influences, such as family and friends, may influence dietary, exercise and weight loss behaviours( Reference Maclean, Hunt, Gray and Smillie 3 , Reference De Souza and Ciclitira 4 ). Hence the aim of the current study was to explore the social influences in men's accounts of their dietary, physical activity and weight loss behaviours.
Semi-structured interviews were conducted (n 19) with men with a Body Mass Index (BMI) between 24–40 kg/m2, aged 18–60 years living in one county in the South West of the UK. Participants were healthy, not dieting or usually active. Participants took part in one interview with the researcher and completed a short socio-economic status questionnaire at the time of the interview. Ethical approval was obtained from Oxford Brookes University. Interviews were audio recorded, transcribed verbatim and coded line-by-line using Thematic Analysis( Reference Braun and Clarke 5 ) and NVivo 11 software.
Six themes were inductively derived from the data; The Influence of Family, The Influence of Partners, The Influence of Friends and Peers, Interactions with Professionals, Society and Culture, and Weight Loss Groups. Among the men that were fathers, their food and physical activity decisions were influenced by concerns for their children's health as well as their own. Fathers were responsible for their child's food education, not food intake. Engaging in active play with their children was a key construct in being a good father. Partners were included in goal-sharing and decision making regarding food and weight loss. They heavily influenced the meals that were eaten within the home environment. Partners primarily promoted weight loss diets rather than physical activity, however, some men did not feel they needed any weight loss support at all. Men talked to their friends about exercise and food intake in general, but not for “support”. Many discussed their doctor as a source of support and information. Men of all ages discussed health and weight concerns, with several voicing body image dissatisfaction. To gain a deeper insight into the role of family members on male weight loss behaviours, future research could include interviews with men's partners and children.
