In healthy men aged 20–35 and 65–80, drinking 600 mL of yogurt leads to lower peak levels of blood glucose and insulin after eating than drinking 600 mL of whole milk, even when the macronutrient content is the same.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Systematic Review and Meta-Analysis of Yogurt vs. Whole Milk on Postprandial Glucose and Insulin in Healthy Adult Men
Population: Healthy men aged 20–35 and 65–80; Intervention: 600 mL of yogurt; Comparator: 600 mL of whole milk with matched macronutrient profile; Outcome: Peak postprandial glucose and insulin concentrations; Duration: Single-meal challenge across multiple studies.
Double-Blind, Crossover RCT of 600 mL Yogurt vs. 600 mL Whole Milk on Postprandial Glycemic and Insulinemic Responses in Healthy Men
Population: Healthy men aged 20–35 and 65–80; Intervention: 600 mL yogurt; Comparator: 600 mL whole milk with identical macronutrients; Outcome: Peak glucose and insulin concentrations measured over 120 minutes; Duration: Single-meal test with washout period.
Prospective Cohort Study of Daily Yogurt vs. Whole Milk Consumption and Postprandial Glucose/Insulin Responses in Healthy Men Aged 20–35 and 65–80
Population: Healthy men aged 20–35 and 65–80; Intervention: Daily consumption of 600 mL yogurt; Comparator: Daily consumption of 600 mL whole milk; Outcome: Repeated postprandial glucose and insulin measurements over 6–12 months; Duration: Longitudinal follow-up.
In Vitro Analysis of Fermented Dairy Metabolites on Intestinal Glucose Transport and Insulin Secretion in Human Enterocytes and Beta Cells
Population: Human intestinal epithelial cells and pancreatic beta cells; Intervention: Exposure to metabolites from fermented yogurt; Comparator: Exposure to equivalent metabolites from unfermented milk; Outcome: Glucose transport rate and insulin secretion kinetics; Duration: Acute exposure (minutes to hours).
Animal Model Study Comparing Effects of 600 mL Equivalent Yogurt vs. Whole Milk on Postprandial Glucose and Insulin in Male Mice with Humanized Gut Microbiota
Population: Male mice with humanized gut microbiota; Intervention: Oral gavage of 600 mL equivalent of yogurt; Comparator: Oral gavage of 600 mL equivalent of whole milk; Outcome: Postprandial blood glucose and insulin levels; Duration: Single-dose challenge with repeated measures.
