The debate over whether carbohydrates are a positive or a negative part of a healthy diet has been heated in recent years. Understanding the role of carbohydrates in a healthy diet is particularly important for cancer patients because cancer cells require a lot of energy. Carbohydrates are created by plants as a way of storing energy from the sun. They are composed of one or more sugar molecules. Two examples of carbohydrates that are a single sugar molecule are glucose, the sugar found in the blood, and fructose, which comes from fruit. Complex carbohydrates are multiple sugar molecules that are connected into a chain. The main function of carbs is to provide energy. Glucose is the main energy currency that the body uses. Carbohydrates that enter the body as sugar chains must first be broken down into glucose to be used by the cells for energy.

Combining a ketogenic diet with standard chemotherapeutic and radiotherapeutic options may help improve tumor response, although more research is needed. As early as bc, fasting was used as an effective treatment for many medical ailments. Fasting continued into modern times, and in , Guelpa and Marie proposed fasting as an antiepilepsy treatment. A low-carbohydrate, high-fat diet was thought to be an alternative to fasting or starvation, having many of the same desired effects while continuing to nourish healthy cells. The term ketogenic diet KD was later coined by Wilder and Peterman, who formulated the fat-to-carbohydrate ratio that is still used today: 1 g protein per kg of body weight in children and 10 to 15 g carbohydrates daily, and fat for the remainder of calories. Use of the KD as an adjuvant to cancer therapy also began to emerge. In , Braunstein noted that glucose disappeared from the urine of patients with diabetes after they were diagnosed with cancer, suggesting that glucose is recruited to cancerous areas where it is consumed at higher than normal rates. During that same time, Nobel laureate Otto Warburg found that cancer cells thrive on glycolysis, producing high lactate levels, even in the presence of abundant oxygen. Warburg conducted many in vitro and animal experiments demonstrating this outcome, known as the Warburg effect. By the midth century, KD use in epilepsy treatment and cancer research had waned.
