Why is sugar bad for you?

Not only does sugar pack a lot of calories per gram, it also has effects on your hormone levels.

Sugar packs a lot of calories into a small space; this causes obesity. It is also absorbed very quickly, which causes spikes in your blood sugar. The pancreas responds with the hormone insulin, which signals for the sugar to be converted to storage forms. But with too much sugar the pancreas produces so much insulin that the rest of the body eventually stops responding to it. This is called type 2 diabetes.
