Figure 5.

Ghrelin kinetics after solid (left) and liquid (right) meals. Data is expressed as difference vs basal level before beverage and meal (mean ± SE). Time 0 was considered as time after beverage intake. B-CO₂: beverage without carbon dioxide; B+CO₂: beverage with carbon dioxide. No significant differences were found by means of the ANOVA analysis between kinetic values between beverages. However, the area under curve analysis (see Table 4) showed a lower ghrelin decrease in B-CO₂ with respects to water and B+CO₂, which proved to be significant (p < 0.05) during the solid meal.
