About this trial
Ultra-processed food (UPF) intake has been related to negative health effects and incresed energy intake in previous intervention studies. Thus, previous studies have seen weight gain from higher UPF intake which obscures the potentital to see effects on cardiometabolic biomarkers, independent of weight changes. The overall aim of this project is to study the causal effects of a high UPF diet, compared to a nutrient-matched low UPF diet, on appetite and cardiometabolic health in a weight-stable context.
