Carbohydrate restriction through ketogenic diets has been shown to reverse conditions linked to insulin resistance, such as metabolic syndrome, PCOS, and fatty liver. This dietary approach also offers potential benefits for kidney health, countering myths about its harm. Research indicates that ketogenic diets can help restore and support kidney function by effectively addressing diabetes and hypertension, known causes of chronic kidney disease (CKD).
Studies have demonstrated that low-carb diets, including ketogenic ones, can improve kidney function and lead to CKD remission. These diets have been found beneficial even in genetically-linked cases of kidney failure like autosomal-dominant polycystic kidney disease. Contrary to concerns about protein intake, ketogenic diets are typically not high-protein, and there is insufficient evidence to suggest that higher protein consumption negatively impacts CKD progression.
Critical to kidney health is the management of blood sugar and blood pressure, areas where carbohydrate restriction shows promise. Research suggests that even with a relatively high protein intake, a low-carb diet is effective in slowing disease progression in CKD patients. Evidence supports the safety and benefits of ketogenic diets for individuals with type 2 diabetes and reduced kidney function, emphasizing the importance of a properly formulated diet rather than processed 'keto-friendly' products.

Metabolic dysfunction extends far beyond diabetes, influencing a wide range of health conditions that often go unnoticed. Disorders like irritable bowel syndrome (IBS) are linked to reduced mitochondrial activity, which impairs cellular function and contributes to symptoms such as abdominal pain and irregular bowel movements. Crucially, those with IBS are twice as likely to develop metabolic syndrome, showcasing the deep connections between gut health and metabolism.
The impact of metabolic issues is also evident in skin conditions like acne, where elevated insulin levels disrupt hormone balance and increase oxidative stress, leading to acne and other skin disorders. Moreover, metabolic dysfunction plays a critical role in mental health, as seen in the link between unstable blood sugars and depression. The gut-brain axis underscores this relationship, where disturbances in the gut microbiome affect mood and behavior, reinforcing the strong ties between digestive health and mental well-being.
Other significant health challenges like chronic pain, arthritis, and even hearing loss are intertwined with metabolic dysfunction, emphasizing the necessity of holistic health management. Insulin resistance and altered cellular metabolism contribute to muscle loss and joint degradation, while high blood sugar levels correlate with higher rates of hearing impairment. Addressing metabolic health can mitigate these varied conditions, improving overall function and quality of life.
