Ketogenic Diet Market Size, Share & Trends Analysis Report By Product (Supplements, Beverages, Snacks, Others), By Distribution Channel (Supermarket/Hypermarket, Specialty Retailers), By Region, And Segment Forecasts, 2025 - 2030

Ketogenic Diet Market Size & Trends

The global ketogenic diet market size was valued at USD 12.45 billion in 2024 and is projected to grow at a CAGR of 5.8% from 2025 to 2030. The steadily rising prevalence of health issues such as obesity and diabetes among the younger generation and the working-class population has fueled the demand for diet patterns that are wellness-focused. The ketogenic diet has emerged as an effective solution for weight management in individuals, as obesity leads to various lifestyle disorders such as cardiovascular diseases, diabetes, and high blood pressure. Governments and private health bodies have also been promoting the adoption of such practices to improve and maintain the health of the population, aiding the expansion of the ketogenic diet industry.

In recent years, factors such as unhealthy eating habits and sedentary lifestyle practices have led to a noticeable increase in the overweight population worldwide. For instance, according to a report published by the WHO in March 2024, as of 2022, 1 in 8 people globally were living with obesity, with adult obesity having doubled since 1990. Lack of availability of nutritional food products, particularly in emerging economies, has resulted in a substantial proportion of people becoming overweight. The ketogenic diet, which is a high-fat and low-carbohydrate diet, has gained notable traction owing to its positive results across all age groups. Research studies highlighting the impact of such food items on major disorders are expected to boost the popularity of the ketogenic diet. For instance, in August 2024, a study was published in the Nature Journal by scientists at the University of California San Francisco. The study found that this type of diet can be combined with particular cancer therapies to inhibit pancreatic cancer development in mice. Such developments open up the potential adoption of the keto diet among a wider demographic.

Over the past few years, a large number of studies have proven the significance of the ketogenic diet in aiding weight loss and improving overall health. Research studies conducted by major bodies such as the American College of Cardiology and the Academy of Nutrition and Dietetics have shown largely positive results of ketogenic diets in treating several disorders, such as epilepsy, obesity, Alzheimer’s disease, brain injuries, Parkinson’s disease, cancer, and cardiovascular diseases. As awareness regarding health-based lifestyle practices increases, keto has become a highly preferred option for individuals due to its stricter guidelines and potentially faster results. The demand for the keto diet has also impacted the foodservice industry. Many restaurants now offer keto-friendly menu items, with some chains further allowing customers to personalize their meals to fit the parameters of this diet.

Product Insights

The supplements segment accounted for the largest revenue share of 52.0% in the global ketogenic diet industry in 2024. Rising awareness regarding ketogenic food products and a shift towards healthy lifestyle practices have led to a strong demand for keto-based supplements. These supplements are available in three major categories, including powder, capsules, and oil, and help satisfy the requirements of nutrients without needing substantial changes in the regular diet patterns of consumers. Keto gummies have emerged as another popular option that celebrities are promoting, which has helped further strengthen segment demand.

Meanwhile, the snacks segment is anticipated to grow at the highest CAGR during the forecast period. The rapidly increasing popularity of keto-specific food products among younger consumers and adherence to wellness-based lifestyle practices have led to the emergence of snacks as a viable option to provide the nutritional benefits of ketogenic diets. Manufacturers are launching a range of snacking products based on ketogenic diet nutrients, which helps people follow their diet while also enjoying the delicacy of snacks. In November 2024, Krack’d Snacks, a California-based company, launched a line of keto snack products catering to the vegan, keto-friendly, gluten-free, and diabetic-friendly demographics. The line includes the Mylk Chocolate Peanut Butter Caramel Crunch and Mylk Chocolate Aloha Caramel, as well as the Vegan Whyte Chocolate Pumpkin Spice PB Caramel Crunch.

Distribution Channel Insights

The increasing presence of new supermarkets and hypermarkets provides an opportunity for market players to increase their production output and improve their distribution strategies, aiding product demand through this segment.

The online sales channel, meanwhile, is expected to grow at the fastest CAGR from 2025 to 2030. The increasing pace of Internet penetration and widespread adoption of smartphones has created a major avenue for companies offering keto-focused products to drive their sales. With the growing trend of online shopping among younger and working-class populations, various leading e-commerce platforms such as Amazon and Alibaba have increased the availability of ketogenic diet products on their websites. The availability of a wide range of products enables comparison of prices and health benefits.
