Modulating Energy Density in Time-Restricted Eating (MEDITRE)
March 5, 2024 updated by: Candida Rebello, Pennington Biomedical Research Center
The goal of this randomized controlled trial is to test the effect of time-restricted eating (14-hour fast, 10-hour eating window) of a low-energy dense diet (reduced calories per gram of food) in older adults with obesity and insulin resistance. The study aims to determine if modulating the energy density of the diet reduces:
- Insulin resistance and
- Body weight.
Researchers will compare the groups:
- Following time-restricted eating and given a diet reduced in energy density or
- Following time-restricted eating and given a diet typically consumed in this population

Detailed Description
The study is an eight-week randomized controlled double-blinded clinical trial.
Participants will follow time-restricted eating (14-hour fast, 10-hour eating window), and will be randomized to a diet low in energy density or the usual diet.
Meals will be prepared in a metabolic kitchen and dispensed to participants.
Dietitians will monitor dietary compliance.
A blood sample will be drawn and body weight will be measured before starting the intervention and after completing it.
