The ketogenic diet has come to considerable prominence in recent years, thanks in part to growing adoption among celebrities, media personalities, and professional athletes. Keto is currently the diet of choice of Katie Couric, Halle Berry, LeBron James, and Tim Tebow. Alicia Vikander famously used the keto diet to lose weight and gain muscle in preparation for her role in “Tomb Raider,” and three out of five Kardashians agree that keto is the way to go.

These influencers are going keto for the diet’s energy-boosting and weight-loss health claims, and what originally started as a medical experiment is now a rapidly growing industry full of new opportunities for functional food and nutritional supplement brands. Data provided to Nutritional Outlook by Innova Market Insights show that the number of new food and beverage products with keto claims grew five-fold from 2013 to 2017, with keto products diversifying from the sports nutrition category into all manner of food and beverage products.

Keto now has a strong presence in the functional foods industry, with keto cereal, keto ice cream, keto candy, and even keto chocolate chip cookies coming to market. Innova’s data indicate that ketogenic sports nutrition products now account for just 33% of the market, down from 100% in 2013. As more mainstream consumers adopt the keto diet, expect ketogenic functional foods to continue expanding into more categories and SKUs.

Keto supplements are also growing, with keto diet adherents frequently using exogenous ketones to reduce the impact of the “keto flu” (ill feelings keto adopters sometimes experience at the start of the diet). Exogenous ketones are now available as ketone esters, ketone salts, and ketone oils.

As more consumers adopt the keto diet to meet their functional needs, expect new opportunities to open up in keto foods and supplements. Here are just a few of the emerging trends that brands and manufacturers will want to watch.

The Ketogenic Trend: Medical Diet Gone Mainstream

While William Banting’s December 1863 Letter on Corpulence contained the basic principles of what is now known as keto, the modern ketogenic diet came to the fore in the 1920s. Russell Wilder, MD, was an endocrinologist with the Mayo Clinic leading a team of doctors who were developing a new dietary regimen for epilepsy patients.1 Wilder theorized, and later demonstrated through medical trials, that a high-fat, low-carbohydrate diet mimicked the starvation therapy that, at the time, was the leading remedy for severe childhood epilepsy.2 Researchers and clinicians at Johns Hopkins Medicine later built the Ketogenic Diet Center, a clinical and research department dedicated to managing pediatric epilepsy through the ketogenic diet.3

In recent years, though, the ketogenic diet has moved outside of the medical establishment and into the mainstream consumer nutrition market. Functional foods, in particular, are seeing rapid growth of foods that are said to promote ketosis (when the body burns fat for energy).

The Rise of the Keto Food Movement

Mike Salguero, co-founder and CEO of ButcherBox (Cambridge, MA), says the ketogenic trend is growing within the functional food space. He points to new product trends in the Paleo market as evidence.

“There’s a Paleo conference in Austin, Texas, every year called PaleoFX,” Salguero says. “I’ve been going there for a few years, and over the past year or so, the conference has really changed. Paleo is moving toward keto. I’m not sure if it’s because the ancestral health experts are realizing keto is more in line with what our ancestors used to eat, but we’re definitely seeing [ketogenic food] products like Fat Bomb and Bulletproof Coffee at these Paleo events.”

Salguero says the ketogenic food trend is similar to the Paleo trend in that both diets are about eating more like our ancestors ate. Functional foods, he says, are big in keto. But one new development he’s witnessed is the advent of exogenous ketones: “The notion that you can drink something and put your body into ketosis, or use it for energy if you’re already on a keto diet? That’s new.”

Ketogenic Supplements Address the “Keto Flu”

Thom King, president and CEO of Icon Foods (Portland, OR), says the keto trend has given rise to demand for a new kind of supplement: a supplement that serves as a shortcut to ketosis. The ketogenic diet, King says, requires its adherents to work harder to stay hydrated, especially in the early stages. Switching to a ketogenic diet also places stress on the body as the body learns to stop burning sugar for fuel and start burning fat. For the first several days of a keto diet, dieters commonly report flu-like symptoms for this reason.

“Staying hydrated is critical, and so is making sure you have plenty of electrolytes,” King says. “That’s why there are more and more keto RTDs and drink mix packets that contain sodium chloride, potassium chloride, and other electrolytes. Many consumers are also looking for shortcuts to get them deeper into ketosis. There are exogenous ketone salts like BHB (beta-hydroxybutyrate), but the most effective supplement by far is exogenous ketone esters.”

Ketogenic supplement brands like Perfect Keto (Austin, TX) offer consumers multiple kinds of supplements that claim to ease the keto flu, ranging from ketone salts to esters to oils. Other brands, like Sated (Cambridge, MA), have formulated such ingredients into ketogenic powders and RTD shakes. Sated founder and CEO Ted Tieken says the keto flu is usually the result of one of two potential causes: either the body is resisting the switch to burning fat instead of sugar, which typically lasts for the first four days of a keto diet, or the consumer is suffering from low electrolytes.

“In the first case, there’s not really much you can do,” Tieken says. “In the second case, many keto brands, Sated included, have incorporated electrolytes into their products.”

The keto industry’s future growth may depend on making consumer transitions to keto diets easier. Expect electrolyte-enriched products and keto flu–busting supplements to continue gaining popularity.
