*Note: In cases of renal insufficiency, lower protein amounts should be administered (Refer to the Renal Chapter).

In the case of insulin resistance combined with weight loss, energy intake from fats should be increased while energy from carbohydrates is reduced. This results in both higher energy density and lower glycemic load (due to the high cellular division rate of cancer cells, they have a particularly high energy demand, which they mainly cover with glucose).

Vitamins, Minerals, and Trace Elements

• Daily vitamin and mineral requirements should be covered according to DACH guidelines.
• High-dose supplementation of micronutrients is only indicated in cases of specific deficiencies.
