Ingested carbs need to go somewhere. Brain consumes a bit, and the remaining part is the problem. If one has enough physical activity, carbs get burned in muscles. Otherwise, they are converted into fat,
carbs don't just stay here waiting (like gaz in a car's tank)
body will process them, depending on tons of hormonal messages.
carbs will get used and making fat is only one of the possibility the body will choose.
e.g.: if you do sports, not only will you burn carbs for energy during the sport, but you will raise the level of some growth hormone, encouraging your body to use the available resources to build more mudcles instead of storing them in long term.
remain in bloodstream (this is diabetes) until cleared by kidneys.
huh.. Nope. not at all.
diabetis is absolutely not "the excess sugar in the blood".
diabetes is mainly the signaling pathway that normally orders the uptake of the sugar being broken.
the two types of diabetis are due to which step of the pathway is broken .
(either the production of insulin, or the receptors that should.detect it)
the fact that people who overeat have an increased risk of diabetis isnt due to extra sugar staying in the blood, it's due to the body getting desensitized tobthe insuline (mainly because to avoid having extra sugar in the blood the body will secrete extra insulin, but over time that extra insulin will down regulate the receptors, leading to the oathway not working that well anymore) (also fat tissue also secrete it's own signaling hormones. obese patients have so much of fat, that they produce excessive amiunt of some hormone and their signaling disturbs other pathway)
so excess sugar isn't the cause of diabetes (and is actually correctly compensated at the beginning) it's the result of an insulin pathway that got fucked up, e.g. by the bad eating habits.
