The average person doesn't think "sugar = energy". They think "sugar = tastes good". When average Joe with his 20 kilo spare tire is hungry (or probably just bored if he's a Western office worker) and trying to satiate himself with either a small bag of almonds or a Milky Way, his subconscious is going to reach for that candy bar every time. Even having learned the good knowledge you describe, the little 5 year old voice that says "I want it!" is going to overrule the adult brain that should know better. I spent a summer working* a Dairy Queen in high school. EVERY SINGLE DAY someone, usually obese, would come in, order an extra large blizzard and say "I really shouldn't do this..." while receiving their paper cup of crack. It is good that you have knowledge and numbers to help you make better choices about your diet. It is unfortunate that knowledge and numbers don't drive better food choices for everyone. *I wasn't really employed there, my buddy managed the place and I'd hang out and occasionally work the register while he smoked a joint out back.
