NCT04487678

Brief Summary

The aim of this pilot study is to investigate the metabolic effects of exogenous ketone ester food supplements, by assessing the change in blood acid-base balance, and the level of blood beta-hydroxy-butyrate in people with type 1 diabetes during resting conditions.

Outcome Measures

Primary Outcomes (1)

  • Change in venous blood pH

    Change in blood pH over a 3 hour period from baseline following ingestion of a ketone ester drink

    3 hours

  • Blood glucose concentration

    3 hours

  • Substrate oxidation rates determined using indirect calorimetry, via RER (respiratory exchange ratio)

    3 hours

  • Gastro-intestinal distress symptoms via a questionnaire

    3 hours

Study Arms (2)

Low-dose KE

EXPERIMENTAL

141 mg/kg bodyweight of ketone esters

Dietary Supplement: Ketone ester supplement

High-dose KE

EXPERIMENTAL

282 mg/kg bodyweight of ketone esters

Dietary Supplement: Ketone ester supplement

Interventions

Ketone ester supplementDIETARY_SUPPLEMENT

Participants taking part in this study will receive a drink containing either 141 or 282 mg/kg bodyweight of ketone esters in a randomised order. These doses are in line with recommendations by the company HVMN from which the supplements for this study will be obtained.
