Metabolic Effects of Short-term Ultra-processed Food Intake (MEST-UPF): a Randomized Controlled Trial

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.

Inclusion: Body mass index (BMI) 18.5-30 kg/m2; Fasting glucose < 6.1 mmol/l; Hb >110 g/L; Weight stability the last 3 months +/-5%.

Exclusion: Blood donation or participation in a clinical study with blood sampling within 30 days prior to screening visit and throughout the study; Following any weight reduction program or having followed one during the last 6 months prior to screening; Food allergies, intolerances or preferences preventing consumption of any products included in the study; History of gastrointestinal conditions or major gastrointestinal surgery (Inflammatory bowel disease, Crohn's disease, malabsorption, colostomy, bowel resection, gastric bypass surgery etc.); Type 1 diabetes or type 2 diabetes; Thyroid disorder; Unable to sufficiently understand written and spoken Swedish or English to provide written consent and understand information and instructions from the study personal; Pregnant, lactating or planning a pregnancy during the study period; Current smoking, vaping; Not habitually eating breakfast (<5 times/week); Restrained eating based on the three-factor eating questionnaire.
