Paleolithic Diets vs T2D and Improvements in the Metabolic Syndrome

February 25, 2020 updated by: University of California, San Francisco

Paleolithic Diets and Metabolic Control in Type 2 Diabetes Mellitus

This study proposes to evaluate the physiological effects of eating Paleolithic type diet ("hunter-gatherer's diet") on Type 2 diabetic patients. The diet essentially consists of fruits, vegetables, nuts, lean meats, excludes dairy products and grains.Subjects will be randomized into taking either ADA (American Diabetic Association) recommended diet or Paleolithic diet for 21 days. The research kitchen will provide all food items and total calories in both groups will be adjusted to maintain baseline weight. Blood and urine test will be done in the first 3 days, last 3 days and 1 month after the study period to study and compare the effects of the two diets on subjects glucose control, lipid profile and other parameters of cardiovascular physiology.

We hypothesize that a palaeolithic diet in subjects with Type 2 diabetes mellitis, will result in improvement in above parameters and lead to improvement in glucose control with less need for diabetes medicines (either lower doses or fewer medications) to a greater extent than in subjects fed with ADA diet, without any change in weight. We also expect a beneficial effect on blood vessel function, lipid profiles and blood pressure.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
22

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: A
Subjects will be placed on Paleolithic diet and markers of insulin resistance, lipid profiles and vascular reactivity will be measured. a paleolithic diet excludes dairy, grains, legumes and processed foods.
Other: Paleolithic diet

Active Comparator: B
Subjects will be placed on ADA ( American Diabetes Association) recommended diet and markers of insulin resistance, lipid profiles and vascular reactivity will be measured. An ADA diet is lower fat and more whole grains.
