Therefore food intake wasn’t reduced in response to a liquid extra caloric load and wasn’t increased after an aspartame drink. There was no change in hunger ratings after the beverages in any of the sessions. Secondary The E– drinks were significantly less palatable than the Eþ drinks. Tabular Summaries Table Lavin et al.

Significant differences, pairwise comparison was performed using the Wilcoxon signed-rank test, followed by Bonferroni’s correction to account for multiple comparison Primary: No statistically significant difference between aspartame, sugars and water on appetite Secondary Glucose stimulated GLP-1 (P=0·002) and peptide tyrosine tyrosine (PYY; P=0·046) secretion and reduced fasting plasma ghrelin (P=0·046), AS did not affect gastrointestinal peptide secretion with minimal effects on appetite. Hunger: No effect No significant difference between the AS, glucose, fructose and water on satiety. The AS increased satiety and fullness and reduced hunger ratings to an amount that was intermediate between the carbohydrate sugars and the water control. Tabular Summaries Table Holt et al.
