About this study

Official title: Effect of a High Protein Breakfast on Glycemic Control, Insulin Sensitivity, and Beta Cell Function in Individuals With Type 2 Diabetes (T2D)

This study examined the effect of a high protein or high carbohydrate breakfast on the glucose and insulin response following the breakfast meal, as well as the subsequent response following the lunch meal.

Read the detailed description

Twelve habitual breakfast consumers with type 2 diabetes (T2D) were recruited for the study. They completed two, 7-day conditions in random order with a minimum of a 7-day washout period between study days. They consumed either a high protein (PRO) or high carbohydrate (CHO) breakfast for 6 days of acclimatization, and on the seventh day, they reported to the lab at 0700 hours following a ~12 hour overnight fast and underwent forearm catheterization before a baseline blood draw. The participants consumed the respective breakfast at ~0730 hours. Four hours post-breakfast, subjects consumed a standard lunch meal. Blood samples were taken continuously throughout the 8-hour test day.

    Measured: 0-240 and 240-480

Secondary outcomes (1)
  1. Post-meal Level of Glucose-dependent Insulinotropic Peptide (GIP) (AUC)

    AUC for 4 hr after breakfast and after lunch

    Measured: 0-240 and 240-480

Questions about this trial

What is this clinical trial studying?

A study testing High protein breakfast and High carb breakfast in people with Type 2 Diabetes, run by University of Missouri-Columbia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma Glucose Level Post-meal (AUC [0-4]) (time frame: 0-240 and 240-480). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02180646, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Oct 2019.
