Scientists have known that calorie restriction, when accompanied by optimum nutrition (also known as C.R.O.N.) can extend the lifespan of animals 30 to 230 %, depending on the species. Primate studies are in process. It will be another 10 years before we known the final results, and no doubt, results will then lead to even more questions. What we do know, from major studies of centenarians already underway, is that the demographics have nothing much in common. Many centenarians are smokers, for example. They come from all over the world without favoring any geographic location in particular. However, there are 3 consistent blood metabolic indicators of all centenarians that are relatively consistent: low sugar, low triglyceride, and low insulin. All three are relatively low for age. Among these three variables, insulin is the common denominator. The level of insulin sensitivity of the cell is one of the most important markers of lifespan. Many lifestyle factors can contribute to a resistance to insulin, so in this article, we will go into what exactly this means, what it affects, and how to reverse insulin resistance naturally: https://www.drlam.com/blog/progesterone-cream-and-adrenal-fatigue/961/
When we eat, the food we consume turns into sugar once inside the body. This is particularly true of carbohydrates such as potatoes or rice. This sugar circulates within us, and under the influence of insulin, is absorbed into the surrounding cells and tissue where it is metabolized into energy, or in the case of excessive sugar, stored for future use.
Insulin is commonly known as a hormone secreted by the beta cells of the pancreas that lowers the blood sugar by promoting their transport from the bloodstream to the cell. Cells, in turn, use sugar as fuel to generate ATP, the energy currency of the body. Insulin’s real purpose in our body is to help the body store excess nutrients.
When we take in excessive sugar and once the body senses that there is too much then insulin is released to take the excess sugar out of the bloodstream and store it by converting it into glycogen. The amount of glycogen stored in the liver is small. The entire reserve cannot last more than a day of activity. Excess sugar above and beyond what can be stored as glycogen is then stored as palmitic acid, a saturated fatty acid. Now you see how excessive sugar (calorie) intake leads to extra fat in the body.
Carbohydrates and Insulin
Carbohydrates we eat fall into two groups -complex and refined. Examples of complex carbohydrates include whole grains, vegetables, whole fruits, nuts, and legumes. Legumes, in particular, can help reverse insulin resistance naturally. Examples of refined carbohydrates include white flour, white rice, and sugar.
All carbohydrates are broken down into sugar once inside the body. Some are broken down slower than the others. The ones that break down slowly are called low-glycemic carbohydrate, such as legumes, apples, cherries, above ground vegetables. Other carbohydrates break down faster into sugar. These are called high glycemic carbohydrates. Examples are wheat, rice, tubers vegetables (potatoes), watermelon, and banana See more
