The Effect of Phosphorus on Diet Induced Thermogenesis

November 2, 2015 updated by: Maya Bassil, Lebanese American University
The aim of the trial is to investigate the effect of ingestion of 75g of glucose (with or without phosphorus) on diet induced thermogenesis (using indirect calorimetry) and appetite (using visual analogue scales) in lean and obese healthy subjects
