Dairy-based proteins, particularly whey, improve insulin sensitivity and muscle protein synthesis more effectively than other protein sources due to their insulinotropic properties and leucine content.

Incorporate 2-4 servings of dairy or 20-84g of whey protein daily. Whey is particularly effective because it stimulates insulin release without spiking blood sugar, helping to manage glucose and build muscle. Yogurt with probiotics is also beneficial for gut health and insulin sensitivity.

GoodSupportsHIGH confidence
The milk proteins, casein and particularly whey, have insulinotropic properties, meaning they enhance the release of insulin, while maintaining a low glycemic response.
