What chocolate actually does
Chocolate is the slowest-moving candy there is: cocoa butter is a heavy dose of fat that slows the sugar's absorption, giving milk chocolate a tested GI of just 43. A standard bar still carries 26 g of carbs, but they arrive over a long stretch rather than as a spike — which also makes chocolate a famously bad choice for treating lows, since you need speed and chocolate delivers a slow drip. Darker chocolate shifts the ratio further: 85 percent dark has roughly half the sugar and double the blunting fat, and a couple of squares barely register for many people. The gotchas are fillings — caramel, cookie pieces, and nougat add fast sugar on top of the slow base.
Slower than candy has any right to be — cocoa butter drags the peak past an hour.
Worth trying
A square or two of dark chocolate after a meal is one of the lowest-impact ways to have dessert exist in your life. Keep chocolate out of your low-treatment kit — it is too slow for that job.
Common questions
Is dark chocolate OK for diabetics?
It is one of the friendlier sweets — 70–85 percent dark runs 10–15 g of carbs per 1.5 oz with lots of fat slowing it down, and a square or two often barely moves the line. Milk chocolate doubles the sugar but is still slower than most candy. Portion does the deciding, as always.
Why shouldn't I treat a low with chocolate?
The fat that makes chocolate gentle on the way up makes it slow when you need speed — a dropping low needs fast glucose, and chocolate's sugar can take 30–60 minutes to fully land. Glucose tabs, juice, or regular candy like Skittles work far faster.
