Plain English Summary
Background and study aims
Type 2 diabetes mellitus (T2DM) is a growing problem worldwide. People with T2DM have difficulty controlling their blood sugar (glucose) as they do not produce enough insulin to function properly (insulin deficiency), or that the body’s cells don’t react to insulin as they should do (insulin resistance). Prediabetes is a condition where a person’s blood sugar levels are higher than normal, but nor high enough to be classified as T2DM. If left untreated, then prediabetes can turn into T2DM. In people with T2DM and diabetes, when sugar is consumed it causes blood sugar levels to rise as there is not enough insulin (or the insulin is ineffective) to store the sugar for when it’s needed later. KarboLyn® is a designer sugar originally developed for athletes interested in carbohydrate loading (a technique used to maximize storage of energy for exercise). It has been shown to be quickly stored in the body without the ending ‘crash’ that often accompanies these energy bursts. The aim of this study is to look at the way KarboLyn® is broken down and stored in healthy volunteers and those with prediabetes and T2DM compared to glucose.
Who can participate?
In part one, healthy volunteers and those with prediabetes aged 21 or over can take part.
In part two, diabetics aged 21 or over can take part.
What does the study involve?
In part one, participants are asked to fast for eight hours before the study visit and are randomly allocated to one of two groups. Those in the first group consume 50g KarboLyn® and those in the second group consume 50g glucose (sugar). All participants are then asked to walk on a treadmill for two hours. At the start of the study and then 15, 30, 45, 60, 75, 90, 105, and 120 minutes after consuming the sugar, participants stop and have a blood sample taken which is used to measure blood sugar levels.
In part two, participants are asked to fast for eight hours before the study visit and not to take their diabetes medication. At the study visit, all participants consume 10g KarboLyn® and are then asked to walk on a treadmill for two hours. At the start of the study and then 15, 30, 45, 60, 75, 90, 105, and 120 minutes after consuming the sugar, participants stop and have a blood sample taken which is used to measure blood sugar levels. One week later, participants return for a second study visit which is exactly the same except they consume 10g glucose instead.
What are the possible benefits and risks of participating?
There are no direct benefits involved with participating. There is a small chance of pain or discomfort when blood samples are taken. In part two, diabetic patients may experience a spike in blood sugar which may make them feel unwell.

Condition
Diabetes
Intervention
Part 1:
After an 8-hour fast (minumum), normal and pre-diabetic volunteers are randomized to one of two groups.
Group 1: Participants receive 50g KarboLyn®
Group 2: Participants receive 50g glucose
Following consumption of the study sugar, participants are asked to walk on a treadmill (~1mph) for a period of 2 hours. At baseline, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes, 105 minutes, and 120 minutes, participants stop and have blood samples drawn in order to measure blood glucose levels.
Part 2:
All diabetic volunteers are withdrawn from their oral diabetic medication for one cycle and fast for a minimum of 8 hours prior to commencement of the study. All participants receive KarboLyn® (10 grams) and are then asked to walk on a treadmill (~1mph) for a period of 2 hours. At baseline, 15 minutes, 30 minutes, 45 minutes, 60 minutes, 75 minutes, 90 minutes, 105 minutes, and 120 minutes, participants stop and have blood samples drawn in order to measure blood glucose levels.
After one week ‘off’, the same volunteers are treated in the above manner prior to receiving 10 grams of glucose. Blood draw conditions and timing are the same.
