My wife found this on a fitness site and it doesn’t make sense to me, any thoughts?
The type of protein may also play a role. There is some research that supports the notion that diets high in animal protein may decrease insulin-sensitivity, causing an increase in insulin secretion. Insulin-sensitivity and high levels of circulating insulin are associated with decreases in fat oxidation and the promotion of fat storage, leading to the development of obesity.
Although dietary protein by itself does not increase insulin release, it can enhance the insulin response to a meal containing both carbohydrate and protein. Plant-based diets that are high in legume proteins are also higher in fiber, slowing digestion and absorption, and decreasing the insulin response. Soy has the additional benefit of enhancing fat oxidation compared to animal proteins through its greater stimulation of the release of glucagons, a hormone that enhances fat oxidation
