When insulin levels go down, your kidneys get rid of more water and salts, so you need to drink fluids with minerals to stay hydrated.

Reduced ENaC activity and blood pressure in mice with genetic knockout of the insulin receptor in the renal collecting duct.
When insulin doesn't work properly in the kidneys, mice lose more salt and water in their urine. This matches the idea that low insulin can lead to more fluid and mineral loss, so you'd need to replace those minerals to stay hydrated.
Interaction between Effects of Insulin and Vasopressin on Renal Excretion of Water and Sodium in Rats
When insulin levels are low, the kidneys get rid of more water and salt in urine. This study shows that giving insulin reduces water loss and affects salt balance, which supports the idea that low insulin can lead to dehydration and mineral loss.

Effect of insulin on uric acid excretion in humans.
The study looked at what happens when insulin is increased, not decreased. It found that more insulin makes the kidneys hold onto sodium, so less is lost in urine. This suggests lower insulin might cause more sodium loss, but the study didn’t actually test low insulin.
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
