Clinical trials: Ultra-Processed Food Intake
Eating Rate
Impact of the Eating Rate of Ultra-processed Foods on Dietary Intake Behavior and Metabolic Responses
The aim of this balanced-order block randomized controlled cross-over trial with 2 treatment arms is to determine the effect of eating rate (ER) of ultra-processed food diets (UPF fast ER vs UPF slow ER) on ad libitum energy…

Healthy Diet
Effect of Ultra Processed Versus Unprocessed Diets on Energy Intake
Background: Eating too much processed food is believed to lead to obesity. But the effect of processed food on energy intake has not been carefully studied.

Obesity; Excess Calories
Speed Limits: Food Intake and Eating Behaviour of Ultra-processed and Unprocessed Foods
Rationale: Foods that can be eaten at a fast rate - with low mastication effort - lead to shorter orosensory exposure (OSE) per unit of food consumed.
