Beta

The glucose, like all of the nutrients, soon gets absorbed into the bloodstream creating a peak in what we call «blood sugar levels», which results with the releasing of more insulin from the
pancreas in order to push glucose to the
cells, basically «commanding» the
cells to open up and absorb it, where it gets used
as an energy source.
As a result, your pancreas starts pumping out more insulin, which is responsible for the transport of glucose to the cells, where it is either stored as fat, or burned as a fue
As a result, your

as fat, or burned

Insulin is a «storage hormone» produced by your
pancreas and allows nutrients to enter your
cells and
as such can promote fat storage while inhibiting fat burning.
But making the body run on ketones means that it will become more sensitive to any glucose you take in from carbs — you won't need
as much insulin to deliver it to your
cells, and that provides a big relief to your
pancreas.
As blood sugar levels rise, insulin is released from the
pancreas to shove that sugar into your
cells for energy.
Insulin is a hormone created by the
pancreas, which must be present in order for glucose to get into our

as food).
Type 1 diabetics would benefit more from a low carbohydrate and low glycemic diet
as the nature of the type 1 is an autoimmune attack on the

The
pancreas produces insulin to help get your

as a result of metabolism.
This process triggers the release of insulin from the
pancreas, which sends food to
cells, and any leftover sugar is stored
as fat, which contributes to weight gain and obesity.
As cells become more insulin resistant, the
pancreas faithfully cranks out even more insulin, causing levels of C - reactive protein to rise in the body — which triggers cellular inflammation.
Obesity leads to insulin resistance, and our blood sugars start to go up, so our
pancreas starts pumping out more insulin to try to force more sugar into our muscles, and eventually the fat spills over into the
pancreas as well, killing off the insulin - producing
cells, and we've got diabetes — in which case we may have to start injecting insulin at high levels to overcome the insulin resistance, and these high insulin levels promote cancer.
As the blood sugar becomes more regulated, the insulin sensitivity returns to the
cells and the
pancreas heals.
Likewise, higher and higher amounts of insulin to deliver glucose
as fuel to your
cells burn out your
pancreas.
As a result, the
cell nucleus doesn't hear the signal and doesn't call your
pancreas to secrete the appropriate amount of insulin needed.
This insulin resistance then requires the
pancreas to secrete more and more insulin to overcome this resistance which leads to higher and higher insulin levels which leads to more and more deposition of fat into fat
cells resulting in obesity
as well
as metabolic syndrome which entails diabetes, hypertension, and vascular disease, ie heart disease and strokes.
