It is not abuse, it is biochemistry. Your body is extremely efficient at absorbing carbs because in nature they only appear mostly encapsulated in fiber which gates their abortion. If you absorb a large amount of sugar your body has to immediately turn it to fat with insulin or you die. This results in a situation where you have met your caloric needs for the day but you will get very hungry again even though you met your needs. Most people can't deal with that and succumb to the natural desire to eat. The high sugar loading destroys your satiety mechanisms.
- cheesymuffin 8y agoYour post is very well-written, but fructose does not affect insulin. Fructose is absorbed directly in the gut and converted to starch in the liver. I don't want to stop the anti-carb echo chamber, though, because it's helped a lot of people.
- edoo 8y agoHigh fructose consumption has its own set of health problems. There is still a lot of glucose in fruits. There is usually a large difference in glycemic index for whole/juiced fruits. Soda being mostly high fructose corn syrup still has a tremendous glycemic load.
- TheSpiceIsLife 8y agoThis doesn't sound right. The Wikipedia entry for fructose[1] has this to say: Excessive consumption of fructose may contribute to insulin resistance, obesity, elevated LDL cholesterol and triglycerides, leading to metabolic syndrome, type 2 diabetes and cardiovascular disease. So it would appear fructose does cause an insulin response. However, it then goes on to say: Uptake of fructose by the liver is not regulated by insulin. However, insulin is capable of increasing the abundance and functional activity of GLUT5 in skeletal muscle cells. (emphasis mine) GLUT5 is also expressed in skeletal muscle,testis, kidney, fat tissue (adipocytes), and brain.[2] 1. https://en.wikipedia.org/wiki/Fructose https://en.wikipedia.org/wiki/Fructose 2. https://en.wikipedia.org/wiki/GLUT5 https://en.wikipedia.org/wiki/GLUT5

- ZeroFries 8y agoInsulin doesn't turn sugar into fat. It causes cells to uptake nutrients, including glucose, to be used as fuel. Only the liver converts sugar into fat, and the effect is pretty minimal, on the order of a few grams of fat per day (outside of a hyper-caloric diet).
- cheesymuffin 8y agoLipogenesis does not only occur in the liver. Lipogenesis occurs in adipose cells as well, and insulin stimulates this process.
