Brief Summary

Gut hormones have therapeutic potential in the prevention and treatment obesity and type 2 diabetes (T2D). Rodent evidence suggests that calcium may stimulate gut hormone secretion. Evidence in humans however, is lacking. This study aims to assess whether the calcium ingestion stimulates gut hormone availability in humans.

Conditions

Obesity; Diabetes
