“Go the old-fashioned way,” Cellini suggests. Avoid minute rice and instant oatmeal, and cook beans from dried rather than buying them canned. The pre-processing that makes these foods more convenient also speeds the rate at which their sugars enter your bloodstream.

Fruits you eat whole tend to have a lower glycemic index than those you peel. So put blueberries instead of bananas in your cereal, and slice apple instead of melon for a snack.

Craving sweets? Eat chocolate-covered almonds instead of pure chocolate. The fat and fiber of the nuts balances out the chocolate’s effect on your blood sugar—plus, you’ll feel full sooner.

Choose bread with a 5:1 (or less) ratio of carbs to fiber. For instance, if there’s 4 grams of fiber per slice, there should be no more than 20 grams of total carbohydrates.
