Insulin has anti-natriuretic actions in the kidney, helping prevent electrolyte loss.

“what we know is that the signaling of insulin a molecule that often gets vilified is critical at the level of the kidney for proper maintenance of electrolytes”

“if you don't have at least phasic meaning spikes of insulin throughout the day or throughout the week you're really not going to be able to hold on to electrolytes at the level of the kidney as much as you want to and that's why so many people on ketogenic diets do more salt and electrolytes than i've ever seen in my whole life it's crazy that's why whole whole companies have arisen around ketogenic diets trying to fill these electrolyte needs of people who have essentially flatlined their insulin signaling and are just wasting electrolytes things like sodium potassium magnesium calcium in their kidneys because there is no or so low signaling of kidney uh insulin level of kidney”

“insulin has been shown to have anti nitric actions in humans and animal mammals nitrous natures is the loss of electrolytes in the kidney”

“the overarching theme of the next few points will be that insulin is beneficial for humans that when you eat carbohydrates things like fruit or honey you do have a postprandial insulin spike some would fear that i would say that is beneficial that is the reason your kidneys are holding on to electrolytes that is the reason you do not have electrolyte problems”

“but I don't really understand why insulin has gotten such a bad rap when it literally Keeps Us Alive and the post-prandial after eating insulin spike is valuable for us at the level of maintenance of electrolytes in the kidney something that I did not learn about in medical school but is clearly documented at the level of glutathione the level of hormones at the level of so many pieces in the human body”
