Inclusion criteria

Inclusion criteria: - Men - Aged between 18 - 60 years - Waist circumference minimal 102 cm (abdominally obese) - Fasting plasma glucose * 7.0 mmol/L - Fasting serum total cholesterol * 8.0 mmol/L - Systolic blood pressure

Design outcomes

Primary

MeasureTime frame
The primary endpoint is the acute effect of inorganic nitrate as compared with placebo on the acute effect of inorganic nitrate as compared with placebo on brain insulin-sensitivity, as assessed by the gray-matter CBF response to intranasally administered insulin using MRI ASL.

Secondary

MeasureTime frame
Secondary endpoints are the acute effects of inorganic nitrate as compared with a placebo on brain vascular function, as assessed by CBF. Additionally, the effect of brain insulin-sensitivity changes on cognitive performance in the domain of executive function and spatial memory will be investigated using CANTAB, after consumption of nitrate as compared with placebo
