How might yogurt exert its satiating effect?

Several factors may account for the satiating properties of yogurt, including nutrient content and effects on appetite-regulating hormones.

• The high protein content of yogurt could partly account for the higher satiety effect of yogurt seen in these findings
• Protein ‘preloading’ – in which small amounts of protein are eaten at a set time before a meal – enhances satiety and reduces appetite
• Other factors that may influence the satiating effects of yogurt include its energy density, the way it is consumed (with a spoon or drunk), and its rate of passage through the digestive tract. The potential effects of fermentation may also play a role.
• Yogurt may influence appetite-regulating hormones in the gut and brain. These may slow stomach emptying and communicate directly with the brain’s appetite-regulation centre.

“Yogurt promotes satiety probably because of the satiating properties of dairy proteins. Its high calcium content might also facilitate appetite control in low-calcium consumers.” – Dr Angelo Tremblay
