Ketogenic Diet Market Report 2026

The ketogenic diet market size has grown strongly in recent years. It will grow from $12.33 billion in 2025 to $13.11 billion in 2026 at a compound annual growth rate (CAGR) of 6.3%. The growth in the historic period can be attributed to increasing prevalence of obesity and lifestyle disorders, rising consumer awareness of low-carb diets, growth of dietary supplement consumption, expansion of health and wellness food categories, increasing influence of fitness communities.

The ketogenic diet market size is expected to see strong growth in the next few years. It will grow to $17.27 billion in 2030 at a compound annual growth rate (CAGR) of 7.1%. The growth in the forecast period can be attributed to increasing personalization of ketogenic nutrition plans, rising demand for plant-based keto alternatives, expansion of online nutrition retail platforms, growing focus on clinical nutrition applications, increasing innovation in keto-compatible ingredients. Major trends in the forecast period include rising adoption of keto-based weight management products, increasing demand for low-carbohydrate functional foods, expansion of clean-label keto ingredients, growing availability of ready-to-consume keto products, enhanced focus on metabolic health formulations.

The increasing prevalence of health issues, such as cardiovascular diseases, is expected to drive the growth of the ketogenic diet market going forward. Cardiovascular diseases (CVDs) are a group of disorders affecting the heart and blood vessels, often leading to conditions that impair normal cardiovascular function. Ketogenic diets shift the body’s primary fuel source from carbohydrates to fats, promoting ketone production, which studies suggest may provide an alternative and potentially more efficient energy source for the heart. For example, in June 2023, the Institute for Health Metrics and Evaluation, a US-based public health research institute, reported that over half a billion people globally were living with diabetes, a number expected to exceed 1.3 billion by 2050. Therefore, the rising prevalence of health issues, such as cardiovascular diseases, is fueling the ketogenic diet market.

Leading companies in the market are launching innovative products, such as clinical trials focused on ketogenic therapy, to explore dietary strategies that may enhance mental health outcomes and provide alternatives to conventional treatments. These clinical trials are systematic research studies aimed at assessing the safety, efficacy, and potential advantages of a ketogenic diet as a treatment for various medical conditions, particularly neurological and psychiatric disorders. For example, in February 2024, McLean Hospital, a psychiatric facility in the United States, collaborated with the Baszucki Family Foundation, a U.S.-based philanthropic organization, to initiate a clinical trial of ketogenic therapy for bipolar disorder. The goal of this trial is to investigate how dietary changes can stabilize mood and improve the overall well-being of individuals with this mental health condition. This initiative highlights the increasing interest in metabolic approaches to mental health treatment and the potential for innovative dietary interventions to complement existing therapeutic options.
