Trial summary

Ketones are a source of energy and signaling molecule that are produced by the body when not consuming any food or consistently eating a low-carbohydrate "keto" diet. Blood ketones can be used as a source of energy by the body, but they may also act as signals that impact how different cells in the body function. Read more about this study

About this study

Ketones are a source of energy and signaling molecule that are produced by the body when not consuming any food or consistently eating a low-carbohydrate "keto" diet. Blood ketones can be used as a source of energy by the body, but they may also act as signals that impact how different cells in the body function.

Recently, ketone supplements have been developed that can be consumed as a drink. These supplements can raise blood ketones without having to fast or eat a "keto" diet. Previous studies have shown that these supplement drinks can lower blood sugar without having to make any other dietary changes. Drinking these ketone supplements may therefore be an effective strategy to improve blood sugar control and influence how cells function.

To find out if it is feasible for people with type 2 diabetes to drink these ketones supplements regularly over 90 days, we will compare between two groups in this study: one group that will be asked to drink ketone supplements, and one group that will be asked to drink a placebo supplement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To determine the feasibility of conducting a randomized controlled trial (RCT) on the effects of consumption of a ketone supplement in adults with type 2 diabetes in free-living environment for 90 days: Recruitment rate of participants into the trial

    A recruitment rate of at least 4 participants per month (which will ensure the study is fully enrolled within a 1-year timeline) will be acceptable.

    Measured: Start of enrolment to completion of enrolment

  2. To determine the feasibility of conducting such an RCT: Compliance as measured by the self-reported volume of ketone supplement drink consumed

    ≥ 67% of the drinks provided being consumed by participants as determined via self-report (i.e., an average of two out of three drinks per day being consumed) will be acceptable.

    Measured: Across the 90-day intervention period (days 0 through 90)

  3. To determine the feasibility of conducting such an RCT: Retention as measured by the number of participants that complete the study

    ≤ 30% of recruited participants dropping out of the study will be acceptable.

    Measured: Across the 90-day intervention period (days 0 through 90)
