Trial Title: Effect of Fermentable Carbohydrate on Glucose Homeostasis

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: TRIPLE
- Phase: None
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Investigation 1 and 3: An oral glucose tolerance test diagnostic of impaired glucose tolerance as defined by the WHO as a fasting plasma glucose\<7.0mmol/l and a 2-h plasma glucose ≥7.8 and \<11.1mmol/l and/or impaired fasting glucose, defined by the American Diabetes Association as a fasting plasma glucose of \>5.6 and \<6.9mmol/L.~* Investigation 2: An oral glucose tolerance test diagnostic of impaired glucose tolerance as defined by the WHO as a fasting plasma glucose\<7.0mmol/l and a 2-h plasma glucose ≥7.8 and \<11.1mmol/l. For investigation 2, people with only IFG will be excluded.~* All investigations:~* Adults over 18 years of age~* Males and Females with a BMI between 25-35 kg/m2. The BMI range of between 25-35Kg/m2 has been chosen as this is the range that the majority of overweight people fall into (1). At this level of overweight and obesity there is an increase in the risk of type 2 diabetes. Above 40 kg/m2 there appears to be decreased success with lifestyle advice.~* The volunteers should have given full written consent.~* Have had a stable body weight for the last 6 months with no more than a 5% change in body weight over 6 months.~Exclusion Criteria:~* Adults less than 18 years of age.~* Volunteers with a major metabolic disease - including diabetes.~* A normal oral glucose tolerance test or that diagnostic of diabetes by the WHO criteria.~* Pregnant and lactating women.~* Males and Females with a BMI less than 25kg/m2 or greater than 35kg/m2~* Volunteers unable to give informed consent for themselves.~* Has lost or gained 5% of their normal body weight in the last 6 months.~* Has a known/diagnosed gastrointestinal problem such as inflammatory bowel disease, irritable bowel syndrome etc~* Failure of the medical examination for inclusion into the study~* Those with anaemia (Hb \<10g/l)~* Drug or alcohol abuse in the last 2 years.
