Zinc is involved in insulin signaling by inhibiting the enzyme protein tyrosine phosphatase to increase phosphorylation of the insulin receptor.

METHODS: We treated 3T3 - L1 adipocytes with 2.5 mmol / l R (+) alpha - lipoic acid for 2 to 60 min, followed by assays of: 2 - deoxyglucose uptake; glucose transporter 1 and 4 (GLUT1 and GLUT4) subcellular localization; tyrosine phosphorylation of the insulin receptor or of the insulin receptor substrate - 1 in cell lysates; association of phosphatidylinositol 3 - kinase activity with immunoprecipitates of proteins containing phosphotyrosine or of insulin receptor substrate - 1 using a in vitro kinase assay; association of the p85 subunit of phosphatidylinositol 3 - kinase with phosphotyrosine proteins or with insulin receptor substrate - 1; and in vitro activity of immunoprecipitated Akt1.

However, while sweet potatoes increase insulin in the short term, they also boost the functioning of the insulin receptors in your glycogen stores thanks to their varied phytonutrients, which allows long - term insulin to fall.

The scientists found that sweet potato starch boosted the function of insulin receptors, meaning that significantly less insulin was required to shuttle energy into them efficiently.

Mercury accumulation can gradually inhibit the responsiveness of insulin receptors in glycogen stores, fluoride in the pineal gland can cause sleep deprivation, and phthalates can increase inflammation around the bodily cells.

Over time, high blood sugar and insulin concentrations promote desensitization of insulin receptors to insulin.

One of them is the gene that promotes the function of the insulin receptors in your glycogen stores.

It basically works by improving the sensitivity of the insulin receptors on your cells, making them better able to utilize insulin.

The problem is that conventional treatments address hyperglycemia which is a symptom and do not do anything to treat the cause: the high insulin levels in the blood and the blunting of the insulin receptors.

Like vitamin D sleep improves insulin sensitivity by maintaining the function of your insulin receptors.

The blunting of insulin receptors is due to inflammation of the cell membrane.

Therefore it's natural that sleep deprivation can affect the sensitivity of insulin receptors.

You need to restore the sensitivity of your insulin receptors by keeping their levels low!

Getting too little sleep also dramatically decreases the sensitivity of your insulin receptors, which will raise your insulin levels.

To protect themselves from this excess energy and subsequent damage, our cells reduce the number of insulin receptors on their surfaces.

It also improves the sensitivity of insulin receptor sites on cells.

The compounds in apples can 1) stimulate the absorption of glucose in your digestive tract, and 2) increase the sensitivity of insulin receptors.

Because cancer requires glucose for energy production, cancer cells possess an overexpression, or abundance, of insulin receptors.
