You may often focus on carbohydrates (carbs) when you’re managing diabetes, but you should also keep tabs on the types of fat you include in your eating plan. Why? Having a diet high in unhealthy fats puts you at higher risk for heart disease—and people with diabetes are already two to four times as likely to develop it as someone who doesn’t have diabetes. Fat also has twice the number of calories compared to carbohydrates, which can contribute to weight gain.
