I try not to borrow information from the internet for this blog, but Mark Sisson nailed it on the head with this simple post. I’ve made proper citations below.

What’s Wrong with Carbs Anyway?

Carbohydrates aren’t bad in and of themselves, but they have the distinct, unique ability to really ravage a metabolically disturbed individual’s body. If you’re overweight, as most people in the United States are, it’s very likely that your carbohydrate metabolism is dysfunctional. You’re probably insulin resistant and even moderate amounts of carbs will do a real number on you, causing a dangerous hormonal cascade: insulin is released to deal with the influx of glucose, but your cells are resistant to it; your blood sugar spikes and the pancreas secretes even more insulin; all that insulin prevents the release of fat from adipose tissue, so you’re not burning any body fat; eventually, since fat cells are resistant and muscle cells are resistant and probably replete, that glucose has nowhere to go but to the liver for conversion into glycogen; the liver fills up pretty quickly, though, after which additional glucose is converted into fatty acids and packaged into lipoproteins; those lipoproteins are then ushered into adipose tissue for conversion to triglyceride, or nice healthy chunks of body fat. You’re probably somewhat sedentary (many jobs, for example, involve eight hours of sitting each day), meaning your muscle glycogen (glucose-derived energy) stores generally stay full, and more carbs means more glucose which will have no where to go but into fat cells. You’re probably exposed to processed food on a daily basis, most of which is carb-and-sugar-based. So, we have a perfect metabolic storm: people eat too much sugar, grain, and vegetable oil, thus destroying their metabolisms and making any amount of carbohydrate a potential problem; they don’t move around enough, so they’re not burning any of the glucose for muscle energy; and everywhere they turn, cheap, simple, and refined carbs wink suggestively, confident that the time-strapped and stressed individual will succumb.
