Carbs are a must because they give your body energy, which you need for everyday life, a healthy mood and brain function, and to fuel your workouts. Leslie said that whole food sources of carbs are best for weight loss because they "break down slowly in the body due to their high-fibre content and help to keep blood sugar levels steady since they are digested slower. They're also richer in nutrients than simple carbohydrates."
Go for whole grains like oatmeal and quinoa, fruits like bananas, apples, and berries, and starchy veggies like sweet potatoes — and avoid refined carbs such as foods made with white flour and sugar.
