What this trial is about
The overall aim of this project is to study the effects of short-term high ultra-processed food intake, compared to nutrient- and energy density matched low ultra-processed food (UPF) intake, on energy intake and appetite. A total of 24 men and women who meet all inclusion criteria and none of the exclusion criteria will be invited to participate. A randomized 2\*2 factorial four-way crossover study will be conducted at the Department of Internal medicine and Clinical Nutrition at the University of Gothenburg, comparing a high-UPF meal to a low-UPF meal also with high and/or low energy density. A supervised breakfast meal will be served, and postprandial blood samples and appetite measures will be collected continuously up to 4 hours after the breakfast meal. Subsequently, an ad libitum lunch meal will be served, and energy intake will be recorded.
