The aim of the study is to compare glycemic responses after consumption of a standard (carbohydrate dense) energy bar and an energy bar with modified macronutrient composition.

Background summary
The energy required for physical activity results from the oxidation of both
carbohydrates (sugars) and fats. During moderate to high intensity exercise,
carbohydrates are the primary source of fuel. When no exogenous glucose is
consumed during exercise, endogenous glycogen stores decrease which result in
diminish performance during prolonged high intensity exercise. Two to 4 hours
before the start of an exercise bout a carbohydrate containing meal is advised
for optimizing liver glycogen stores. However, some people (e.g. athletes) can
produce excessive amounts of insulin after ingestion of such a carbohydrate
meal. This hyperinsulinemic response decreases blood glucose concentrations
resulting in a state of reactive hypoglycemia which is detrimental to physical
health and performance capacity.
Study objective
The aim of the study is to compare glycemic responses after consumption of a
standard (carbohydrate dense) energy bar and an energy bar with modified
macronutrient composition.
Study design
This study consists of a 2 hour screening, followed by 2 complete testdays,
during which 2 energybars with different macronutrient composition will be
consumed. This study is desigend as a cross-over study.
Intervention
The intervention consists of consuming 2 energybars with different
macronutrient composition. Glycemic responses will be measured in venous blood.
Ventilated hood measurements will be applied to determine energy-expenditure.
Study burden and risks
This study consists of a 2 hour screening and 2 complete testdays of 5 hours
each. Possible local is a hematoma at the site of the venapunction.
