Application of New Technologies and Tools to Nutrition Research

The overall objective of the research is to develop new methods for studying the link between diet, health and disease.

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.

  • Obesity
  • Diabetes
Behavioral: Metabolomic and Energy Intake Restriction
Metabolomic inquiry followed by a 12 week energy intake restriction
Other Names:
  • Energy restriction diet
  • Metabolomic
  • Experimental: Life style advice
    reduce energy intake by 20% less than estimated energy expenditure.
    Intervention: Behavioral: Metabolomic and Energy Intake Restriction
  • Active Comparator: UK background diet
    Diet where energy intake will be matched with estimated energy expenditure.
    Intervention: Behavioral: Metabolomic and Energy Intake Restriction
  • 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.
