When there is too much glucose in our bloodstream and our cells already have filled glycogen stores, glucose is stored as fat. This happens a lot more quickly when consuming refined processed carbohydrates and sugary foods. Processed starches, like white bread/rice, along with high sugar foods, are rapidly converted into simple sugars that enter bloodstream and trigger a large release of insulin from the pancreas. The result is usually weight gain, plus even more hunger, which leads to continued overeating and a vicious cycle that makes it hard to stop eating sweets.
The more often and longer that blood insulin levels remain high, the more likely a person is to accumulate excess body fat and to battle weight problems. Insulin also communicates with many other hormones needed for various functions, including those made in the adrenal glands, such as the stress hormone cortisol, so abnormally high levels and hormonal imbalances result in powerful urges to eat, mood changes, lack of energy and various other factors that contribute to disease formation.
