Application of New Technologies and Tools to Nutrition Research (NutriTech)
研究概览
详细说明
The enquiry consists of two part. A metabolomic biomarker discovery study followed by a randomised controlled trial of moderate dietary induced weight loss.
A cohort of moderately overweight men and women will undergo a metabolomic study follow by randomised controlled trial of a healthy diet with a 20% energy restriction for a 12 week period. This intervention will improve the volunteer's body composition and reduce their risk of developing diabetes.
Extensive tests will be conducted before and after the dietary intervention using emerging technologies with current state-of-the-art methods. These tests will monitor the numerous physiological adaptations that have occurred on a gene, cell, organ and organismic level.
The study will, therefore, aim for a scientific breakthrough by developing a series of novel biological "markers" that can accurately determine an individual's health status.

实验性的:Life style advice
reduce energy intake by 20% less than estimated energy expenditure.

Metabolomic inquiry followed by a 12 week energy intake restriction.
This study is part of a very large European study called EPIC.
Only the results by Lee et al. 2016 have been presented here.
The results of the study published by Cheung 2017 are from a different study.
therefore the entries for the results are correct.
For this particular study, participants were not randomly assigned to one of five different diets; red meat, fish, poultry, processed meat or a supplement and vegetarian option.
In summary, both studies (lee and cheung) are considered as separate trials and results of the first phase where participants were assigned to one of five different diets, are reported separately.
Unfortunately no different NCT number is available.

其他:Metabolomic inquiry
This inquiry took place prior to the randomized controlled trial and include 50 volunteers who will then be asked to volunteers of the weight loss study.
Were randomly assigned to one of five different diets; red meat, fish, poultry, processed meat or a supplement and vegetarian option.
