A satiety claim does not influence how full you feel

Satiety, the feeling of being full, is influenced by several factors, including internal cues, e.g. calorie intake, but also external cues like the size of a plate. CLYMBOL researchers wanted to observe the interaction between different amounts of calories and the presence or absence of a satiety claim. As expected, participants who consumed more calories (600 kcal) at breakfast felt fuller for longer, compared to participants who only consumed 300 kcal. However, participants who ate 600 kcal for breakfast only ate 79 kcal less for lunch compared to those who had a lighter breakfast. However, an effect of the satiety claim on participants’ feeling of fullness could not be shown as participants who saw a health claim at breakfast did not consume considerably less calories at lunch compared to participants who did not see a satiety claim.

Study participants were given muesli with different amounts of calories (300 vs 600 kcal) to test whether a satiety claim on the cereal package (‘this muesli contains added fibre, therefore you will feel full for a longer time period’) influenced their feeling of fullness. Participants could eat from this muesli for breakfast. Satiety was then measured by asking them to report their feeling of fullness. Additionally, the amount of calories participants consumed later, at lunch, were measured to observe the effects of the different caloric breakfasts and the presence/absence of a satiety claim on participants’ feeling of fullness.
