Final answer:
De novo lipogenesis from excess carbohydrates results in the production of saturated and monounsaturated fats.
Step-by-step explanation:
When excess carbohydrates are ingested, de novo lipogenesis occurs, which is the process of the body converting those excess carbohydrates into fat. The type of fat produced through de novo lipogenesis is mainly saturated and monounsaturated fats. These fats are stored in the body as triglycerides and can contribute to weight gain and increased risk of heart disease if consumed in excess.
