What the Ketogenic Diet Is
The ketogenic diet is a high-fat, very low-carbohydrate eating plan that shifts the body into a metabolic state called ketosis, where fat becomes the primary fuel source instead of glucose. Standard ketogenic ratios typically aim for around 70 to 75 percent fat, 20 percent protein, and 5 to 10 percent carbohydrates, with daily net carbs often limited to 20 to 50 grams, according to research summarized by the National Institutes of Health here.
Ketosis occurs when carbohydrate intake drops low enough that the liver converts fat into fatty acids and ketone bodies, which the brain and other tissues can use for energy. Clinically, ketogenic diets were originally developed in the 1920s to treat drug-resistant epilepsy in children and are now studied for metabolic syndrome, type 2 diabetes, and neurological conditions, with ongoing trials registered on ClinicalTrials.gov here.
Health and Business Facts About Keto
Reported Benefits and Risks
Short-term studies show ketogenic diets can lead to meaningful reductions in body weight, fasting blood glucose, and triglycerides, while raising HDL cholesterol in some individuals. Potential risks include nutrient deficiencies, kidney stones, elevated low-density lipoprotein cholesterol, and gastrointestinal side effects, especially during the initial adaptation phase.
In the food and wellness industry, the global ketogenic diet market was valued at several billion dollars and continues to grow as consumer demand for low-carb products rises. Companies ranging from specialty snack brands to meal-kit services have introduced keto-friendly lines, and some publicly traded food companies highlight low-carb offerings in their earnings commentary, as noted in recent SEC filings here.

Key Players and Products
Major food and beverage companies have expanded keto-focused product portfolios, including ready-to-eat meals, high-fat snacks, and exogenous ketone supplements. Retail sales data show strong growth in categories such as keto-friendly bars, shakes, and oils, with some brands reporting double-digit year-over-year revenue increases in relevant segments.
Private and public companies in the keto space have raised venture capital and equity funding to scale manufacturing and distribution, reflecting broader investor interest in metabolic health and low-carb nutrition.
