Obese adults’ preferences for fast food, convenience, semi-convenience and home-cooked meals during weight loss and their influence on weight/fat loss.

Fast food consumption has increased significantly over 30 years. No system exists to classify mixed meals/snacks as convenience, semi-convenience, non-convenience or fast food preparation methods. We aimed to determine if an association between meal preparation methods and weight or fat loss existed in obese adults undertaking a 6-month weight loss RCT. Prescribed intakes of 5-7.5MJ were suggested. Weight and fat weight were measured monthly using bioimpedance. Participant dietary records for ≥four months intake, were classified into preparation methods using a system based on literature and dietetic consultation. Regression analysis assessed associations between preparation methods and weight or fat weight; t-tests between low and high consumers of each preparation method and age or gender; and ANOVAs between preparation options available for consumption and consumption frequency. Dietary completers (n=89, 64F:25M) were older (51±13vs.46±13) at baseline and achieved greater 6-month weight (8%±5%vs.3%±5%) and fat loss (12%±13%vs.1%±11%) than non-completers (n=90). Semi-convenience dinner meals were positively associated with 6-month weight (β=0.331,p=0.002) and fat loss (β=0.289,p=0.007). Non-convenience lunch and dinner meals were inversely associated with 6-month weight (β=-0.290,p=0.006) and fat loss (β=-0.267,p=0.012). Consumption was positively associated with preparation options made available (r=0.003-0.69,p=0.000). Regular fast food consumers were younger (48±14vs.56±11 years, p=0.020). This was the first study to investigate preparation methods chosen by obese adults undertaking a weight loss program. Preparation methods may impact health outcomes, including fast food in weight loss diets may not be detrimental to weight loss.
