RELATIVE EFFECTS OF CARBOHYDRATES AND PROTEIN ON SATIETY - A REVIEW OF METHODOLOGY

There is some evidence that the effects of carbohydrates and protein m ay differ with respect to satiety. This may depend in part on the diff erent methods of preparing these nutrients for administration. Additio nal factors such as timing, different delays, differential metabolism and expectations of ingested foods may contribute to different outcome s of experiments investigating the satiating effects of macronutrients . Here, studies of the relative satiating effects of carbohydrates and protein are discussed followed by a methodological discussion of the reviewed studies. Finally, suggestions for methodological improvements are given which should allow future studies to investigate more clear ly the mechanisms underlying satiety. (C) 1997 Elsevier Science Ltd.
