Euglycemic hyperinsulinemic clamp (tissue specific glucose/FA metabolism)Options:
1. Simple clamp: glucose infusion rate as measure for insulin sensitivity
2. Single label clamp: for the measurements of hepatic insulin sensitivity
(glucose production under basal and hyperinsulinemic conditions)
and
whole-body insulin sensitivity (glucose uptake). Reference:
3. Double label clamps: for the measurements of hepatic insulin sensitivity
(glucose production under basal and hyperinsulinemic conditions)
and
tissue specific glucose uptake (muscle, heart, adipose tissue). Reference:
4. Addition of FFA turnover
Other technologies
■ Oral glucose tolerance test, Insulin sensitivity test
■ Glucose-induced insulin secretion by “hyperglycemic clamps”
■ Intracerebroventricular administration
■ Measurement of metabolic parameters and satiety hormones
■ Measurement of food intake and energy expenditure using metabolic cages
