Olive Oil and Cauliflower

At just 27 calories a cup, cauliflower is a diet-friendly food. It’s also low on the glycemic index (GI), a measure of how much a food raises your blood sugar. One study showed that low-GI vegetables led to more weight loss than starchier ones, such as peas and corn. Drizzle chopped cauliflower with olive oil and roast it -- this brings out the flavor, and olive oil’s fats can curb your appetite by making you feel full.
