4. Make it decaf
If you can’t resist a croissant or donut in the morning, drink decaffeinated coffee with it. British researchers found that combining decaf with simple sugars reduces the blood sugar rise that sweet treats create. Caffeinated coffee did not have the same benefit, because while plant chemicals in coffee slow the rate at which your intestines absorb sugar, caffeine delays sugar’s arrival in the muscles, keeping it in the bloodstream longer.
