Brief Summary

The incidence of obesity has dramatically increased during the last three decades, leading to a significant increase of obesity-related morbidity, including type 2 diabetes mellitus (T2DM) that is characterized by resistance of target tissues to insulin action. T2DM obese patients may be treated by medications or by bariatric surgery. Both alternatives have limitations due to incomplete resolution of the diseases, high cost or potential procedural related morbidity. An increasing body of evidence points to a role of the enteric microbiota in the pathogenesis of obesity-related insulin resistance. In addition to that, the gut microbiota is directly affected by the diet composition. Studies in T2DM mice carrying human gut germs, demonstrated special interactions between the gut microbiota and the host, creating a typical microbiota composition which changes significantly following diet change from a western diet, rich with sugar, to a vegetarian diet rich with fibers. This rapid alternations in the microbiota composition has also shown in humans, after changing from western to high fiber diet. A change in diet life style may lead to an improvement in T2DM symptoms such as decrease in visceral adipose tissue.

Outcome Measures

Primary Outcomes (2)

  • 30% decrease in insulin resistance

    Lean donor FMT will result in 30% decrease in insulin resistance that will be further enhanced after a second FMT. These will be meditated by an alteration of intestinal microbiota

    6 weeks after first FMT

  • 40% decrease in insulin resistance compared to baseline

    12 weeks after second FMT

Secondary Outcomes (4)

  • Decreased use of diabetes medications

    Week 6 and 12 post FMT

  • Improvement in anthropometric measures and in metabolic indices

    week 6 and 12 post FMT

  • Maintenance of an improved insulin resistance

    28 weeks post FMT

  • Maintenance of altered of enteric microbiota in the three diet groups

    6, 12, 28 weeks post FMT

Study Arms (3)

FMT from a lean donor+ high fat diet

ACTIVE COMPARATOR

Patients will undergo FMT (Fecal Microboita Transplantation) from a lean donor twice during study through a gastroscopy: 1. at time 0 2. after 6 weeks Patient will start high fat low fiber diet 2 weeks before first FMT and continue on consuming the same diet 9 weeks after the first FMT. Patient will be followed up by a nutritionist through the the study.

Procedure: gastroscopyDrug: Fecal Microbiota TransplantationOther: high fat low fiber diet

FMT from a lean donor+ sham diet

SHAM COMPARATOR

Patients will undergo FMT (Fecal Microboita Transplantation) from a lean donor twice during study through a gastroscopy: 1. at time 0 2. after 6 weeks Patient will start sham diet (no change in fat/fiber consumption) 2 weeks before first FMT and continue on consuming the same diet 9 weeks after the first FMT. Patient will be followed up by a nutritionist through the the study.
