High-dairy diet leads to insulin resistance

Overweight people who consume a high-dairy diet have lower insulin sensitivity than people on a lean red-meat diet, Australian researchers have found.

Their 47-person study shows fasting insulin is significantly higher on a dairy diet than on a red meat diet, suggesting a decrease in insulin sensitivity. The participants were randomised to a high lean red meat diet, a high dairy diet or a control diet with low dairy and no red meat.

The effect is more pronounced for women. In the study, those on a high-dairy diet recorded a 14.7% bigger
