Slimming starters. Intake of a diet-congruent food reduces meal intake in active dieters

Abstract

Dietary restraint is known to break down in the face of tempting foods. Previous research suggests exposure to cues associated with slimming such as images or odours act as prompts to restrict intake of a tempting snack in dieters. The effects of consuming diet-congruent foods on subsequent intake of a meal have not yet been investigated. Thus, using a repeated measures design 26 female participants (dieters or non-dieters) consumed a diet-congruent (100 kcal salad), hedonic (100 kcal garlic bread) or neutral (0 kcal water) preload. A lexical decision task measured the salience of diet and hedonic thoughts and participants were then offered pizza as a main meal. Appetite sensations were measured throughout the study. Compared to the hedonic and neutral preload, a diet-congruent preload reduced dieters' entire meal intake by 21%. In contrast, non-dieters consumed 9% more in the hedonic preload condition compared to the neutral preload, yet showed no differences between the diet-congruent and other conditions. Salad lowered participants desire to eat and increased fullness compared to garlic bread and water preloads. Dieters were also less hungry after the salad compared to the garlic bread and water preloads. Consuming a diet-congruent first course may prompt lower intake at a meal, in part due to facilitating resolve to refrain from overeating a tempting second course.

Associations between nutritional properties of food and consumer perceptions related to weight management

“…For example, future work may apply the platform to improve understanding about the determinants of perceived satiating capacity. This has relevance considering the potential consumer benefits of satiety enhancing foods (Hetherington et al, 2013). Furthermore, research might examine food perceptions under different environmental and physiological conditions, such as how packaging or branding (Cavanagh et al 2014), portion size (Piqueras-Fiszman, Harrar, Alcaide, & Spence, 2011) or nutritional status (Cabanac, 1979;Frank et al 2010) affects food perceptions.…”

“…Perceptions about foods can also reduce food intake. Buckland, et al (2013) found that eating food perceived to be congruent with weight loss goals -caloric food associated with hedonic goals. As perceptions of food play a role in the choice and amount of food consumed, it could be valuable to systematically explore which common dimensions of foods contribute to the strength of consumer perceptions to facilitate healthy eating choices.…”

“…The perception of foods associated with successful weight management is important in part because perception may assist dieters to meet diet-related goals by directing food choices and reducing energy intake (Buckland et al 2013). Therefore, it was of interest to explore how the perception of foods may differ between dieters and non-dieters.…”

Health goal priming as a situated intervention tool: how to benefit from nonconscious motivational routes to health behaviour

“…Seeing or consuming healthy foods has been shown to reduce intake of unhealthy foods, mostly among dieters (Buckland, Finlayson, & Hetherington, 2013a, 2013b; Buckland, Finlayson, Edge, & Hetherington, 2014). Similarly, health primes such as dieting advertisements, compared to control or indulgent food advertisements, can prevent overeating on unhealthy foods, again especially among dieters, and especially in the afternoon (Anschutz, Van Strien, & Engels, 2011; Boland, Connell, & Vallen, 2013; Versluis & Papies, 2016).…”

The Effects of Food Labelling on Postexercise Energy Intake in Sedentary Women

“…Buckland et al [45] demonstrated that a diet-congruent starter (e.g., a salad) was associated with a significant reduction in EI at lunch when compared with a hedonic starter (e.g., garlic bread) in dieters. The labelling manipulation thus likely had reduced impact on the cookies because they are not a diet-congruent food item.…”
