Diet & Fasting

Ketogenic Diet

Within some metabolic approaches to cancer, a rigorous ketogenic diet may be considered with the aim of reducing blood glucose and increasing ketone levels. Some proponents use measures such as the Dr. Boz Ratio and blood glucose/ketone meters to monitor these metabolic changes. The role of ketogenic diets during cancer treatment remains an area of ongoing research. Their suitability may vary according to the individual, their nutritional status, cancer and treatment, and dietary interventions during cancer care should be discussed with appropriately qualified healthcare professionals.

Fasting

Nutrient sensors like insulin, IGF1, mTOR, and AMPK are critical for detecting the levels of macronutrients circulating in our blood. They transmit growth signals to both normal cells and cancer cells, playing a role in how these cells develop and proliferate. By altering our intake of macronutrients, we can potentially influence the growth of cancer cells.

Reducing carbohydrate consumption can lower insulin levels, thereby attenuating growth signaling pathways. Similarly, the mTOR pathway, closely related to protein levels, can be manipulated by dietary adjustments to curb cell growth. AMPK, a sensor for overall caloric intake, provides another opportunity to influence cancer cell development. Through practices like fasting, we can modulate these pathways to potentially impact cancer cell growth.

In the fed state, cell growth occurs; in contrast, the fasting state triggers cell repair, replacement, and recycling. These latter processes are medically referred to as apoptosis (programmed cell death) and autophagy (cellular self-digestion). Both intermittent fasting and extended fasting periods can be utilized to enhance these processes, possibly promoting increased cancer cell death.

Fasting not only boosts the effectiveness of conventional cancer treatments like chemotherapy and radiotherapy but also helps minimize their side effects.

Now, how does this relate to mitochondria? Well, the mentioned nutrient sensors—insulin, IGF1, mTOR, and AMPK—also influence mitochondrial function. Insulin and IGF1, for example, have been shown to affect mitochondrial biogenesis. The mTOR pathway also plays a role in mitochondrial function and dynamics, and AMPK activation helps promote mitochondrial biogenesis and function. Thus, manipulating these nutrient sensing pathways through dietary changes and fasting can also influence the health and function of mitochondria. This can potentially improve overall cellular health, including in cancer cells, and contribute to therapeutic strategies.

Some cancer cells learn to use proteins, fats and even ketones as fuel. There are a number of

supplements and repurposed medications that can reduce the metabolism of these other fuel

sources. Many of these medicines are simple e.g. low dose aspirin.
