What this trial studies

The MEMORY study investigates how specific macronutrient compositions, such as carbohydrates and proteins, influence food preferences and intake across individuals with different body mass indices (BMIs). In this randomized cross-over study, 45 participants aged 18-45 will consume either a carbohydrate or protein liquid meal during two test visits, followed by an ad libitum buffet to assess energy intake. Clinical assessments, blood samples, and questionnaires will also be conducted to gather comprehensive data on appetite and food choices. The study aims to understand the concept of 'food memory' and its implications for obesity management.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-45 with a BMI ranging from 18.5 to 39.9 kg/m².

Not a fit: Patients with eating disorders, significant medical issues, or those on medications affecting appetite may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into dietary strategies that help manage obesity and improve eating behaviors.

How similar studies have performed: While the concept of food memory is being explored, this specific approach to examining macronutrient effects on appetite and intake is relatively novel.
