Food as Metabolic Medicine

 

Most people understand that eating well is important. Far fewer understand why it is so urgent, particularly with a cancer diagnosis, a hormonal condition, or any chronic disease process. The reason comes down to one word: insulin.​

​

Insulin is the master metabolic hormone. When it is chronically elevated, it signals your cells to grow, divide, store fat, and suppress the immune system. It feeds inflammation. And critically, it feeds cancer. Cancer cells express insulin receptors at rates far higher than healthy cells. They are exquisitely sensitive to glucose and to the insulin that shuttles it inside.​

​

This is not a fringe idea. It is the basis of the Warburg effect, first described nearly a century ago, and now central to the metabolic approach to cancer. Cancer cells have impaired mitochondria and are almost entirely dependent on glucose fermentation for their energy. Healthy cells are not. This means that what you eat has the potential to selectively starve cancer while nourishing your healthy tissue.

 

The concept that makes this possible is metabolic flexibility.​

 

What is metabolic flexibility? ​

 

A metabolically flexible body can burn both glucose and fat for fuel, shifting between them depending on what is available. Most people in the modern world have lost this capacity entirely. They run exclusively on glucose, keep insulin chronically elevated, and never access their fat-burning metabolism. This state is called metabolic inflexibility, and it is one of the most significant drivers of cancer risk, hormonal imbalance, cognitive decline, and chronic disease.

 

Restoring metabolic flexibility means training your body to lower insulin, stabilize blood sugar, and access fat as a primary fuel source. When this happens, inflammation decreases, mitochondrial function improves, immune surveillance improves, and the metabolic terrain that favors cancer is fundamentally altered.

 

What this looks like in practice:

 

Foods that support metabolic flexibility and lower insulin are whole, unprocessed, and low in refined carbohydrates. They include non-starchy vegetables, quality proteins, healthy fats from sources like olive oil, avocado, nuts, and seeds, low-glycemic fruits, and therapeutic fats like those found in wild-caught fish and pastured eggs.

 

Foods that drive insulin upward and promote a cancer-favorable terrain include refined sugar in all its forms, processed grains, industrial seed oils, and ultra-processed foods. These are not just empty calories. They are metabolic signals that actively worsen your terrain.

 

Timing also matters. Compressed eating windows, strategic fasting, and avoiding food late at night all contribute to lowering insulin and improving metabolic flexibility. The research on fasting and cancer outcomes is growing rapidly and consistently supports this approach.

 

For those with a cancer diagnosis:

 

Oncology nutrition is not about eating less or following a generic healthy diet. It is about precision. It requires understanding your individual metabolic markers, including fasting glucose, fasting insulin, HbA1c, triglycerides, and inflammatory markers, and designing a nutritional strategy that directly corrects what is dysregulated in your terrain. This is the work Dr. Suhaila does in depth with every patient. Food is not an afterthought in her practice. It is a primary therapeutic intervention.
