Study Notes

Ketogenic Diets

There is no one-size-fits-all ketogenic diet, and health implications should be the primary driver of how the diet should be applied, individualized by the patient, their family, and the health professional.

Benefits of Ketogenic Diets

Evidence suggests possible benefits in epilepsy, cancer therapy, neuroprotective effects, weight and fat loss, anti-inflammatory and analgesic effects, improvement in dyslipidemia, improvement of lung function, gut-brain axis effects, and enrichment of well-being.
Stronger evidence exists for epilepsy, obesity, dyslipidemia, and Alzheimer's disease.

Effective Weight Loss and Fat Loss

The ketogenic diet is an effective weight loss and fat loss intervention, with a higher rate of weight loss and fat loss compared to other diets.
The diet promotes an anabolic metabolic environment, avoiding progressive loss of muscle mass typically observed.
A meta-analysis demonstrated that individuals consuming a ketogenic diet achieved a 5-6% greater weight loss than individuals consuming a low-fat diet.
Weight loss on a ketogenic diet is associated with loss of fat mass, and the intervention has the potential to contribute to substantial weight loss over time.

Improved Insulin Sensitivity and Blood Sugar Control

The ketogenic diet improves glucose metabolism in type 2 diabetes, with a 50% improvement in glucose tolerance and increased fat oxidation.
The diet reduces insulin levels, improves β-cell function, and increases insulin sensitivity.
In one study, the ketogenic diet group showed a 25% reduction in glucose area under the curve (iAUC) and a 55% improvement in insulin area under the curve during a glucose tolerance test.

Enhanced Cognitive Function and Mental Clarity

Fasting for the induction of the ketosis state has been used for millennia, and the presence of ketones increases cerebral ATP levels, having neuroprotective and cognitive benefits.
The ketogenic diet-generated ketone body increase parallels many of the same neuroprotective and cognitive benefits of calorie restriction.
Personal accounts of individuals who experience nutritional ketosis report increased cognitive focus, problem-solving abilities, and memory.

Reduction in Inflammation and Oxidative Stress

The fatty acid composition of the ketogenic diet is characterized by an increase in SFA, which can increase risk factors for CHD.
The diet reduces oxidative stress/formation of mitochondrial ROS, and the activation of uncoupled NO synthase also reduces mitochondrial superoxide formation.
The results are significant because mitochondrial abnormalities have been found in epilepsy and other neurological diseases.
Medium chain TGs are antioxidants under certain neurological disease conditions.
