NCT03222791

Brief Summary

The Personalized Nutrition Project for Prediabetes (PNP3) study will investigate whether personalized diet intervention will improve postprandial blood glucose levels and other metabolic health factors in individuals with prediabetes as compared with the standard low-fat diet.

Outcome Measures

Primary Outcomes (3)

  • Evaluation of the total daily time of plasma glucose levels below 140 mg/dl

    Total daily plasma glucose levels will be evaluated by using a Continuous glucose monitoring (CGM)

    6 months

  • Mean change in HbA1C from the baseline level

    Difference of at least 0.1% in the reduction of HbA1C between control group and experimental group

    6 months

  • Mean change in Glucose Tolerance Test from the baseline level

    GTT glucose values (mg/dl)

    6 months

Secondary Outcomes (2)

  • Change is Fasting plasma glucose from baseline

    6 months

  • Change in HOMA-IR from baseline

    6 months

Other Outcomes (1)

  • Patients compliance evaluation using a compliance questionnaire

    6 months, 12 months

Study Arms (2)

Algorithm-based diet

EXPERIMENTAL

Subjects randomized to this arm will receive personally tailored dietary recommendations based on their predicted glycemic responses according to the study algorithm.

Other: Algorithm-based diet

Mediterranean-style low-fat diet

OTHER

Subjects randomized to this arm will receive nutritional recommendations according to the standard Israeli dietary approach for treating pre-diabetes: Mediterranean-style low-fat diet.

Other: Mediterranean-style low-fat diet

Interventions

Personalized nutrition plan based on an algorithm for predicting the personalized glucose response to food. The algorithm's predictions are based on many personal measurements, including blood tests, personal lifestyle and gut bacteria.

Algorithm-based diet

The Israeli standard of care dietary guidelines for prediabetes.

Mediterranean-style low-fat diet
