Nutrition Innovations

Creation of the Vertical Diet

Stan Efferding conceived the Vertical Diet in the early 2010s, drawing from his own challenges with digestive distress during high-calorie bulking phases for and competitions, where he exceeded 300 pounds and experienced , gas, and metabolic issues from poorly digestible foods like vegetable oils and processed carbs. After undergoing surgery for , Efferding experimented with a simple slurry of mashed and broth to ease and improve gut function, which led to better regularity and reduced inflammation, forming the basis for prioritizing easily digestible, micronutrient-dense foods. This personal trial-and-error approach was influenced by earlier training insights gained while working with bodybuilder , emphasizing nutrient partitioning to support elite athletic performance without digestive compromise. Efferding initially tested the emerging diet on high-level athletes facing similar caloric demands, including strongman Brian Shaw, who weighed over 400 pounds and struggled with gut issues from massive intakes, as well as bodybuilders and other powerlifters requiring rapid recovery and muscle gain. Shaw and peers like Hafþór Björnsson adopted the protocol, reporting enhanced digestion and sustained energy during intense training, with Björnsson reducing from 435 to 395 pounds while maintaining performance markers. These applications refined the diet's focus on and as core staples, adjusting portions based on individual hunger and workout intensity to optimize absorption without overload. Over the mid-2010s, the Vertical Diet evolved from Efferding's experiments into a structured nutritional framework, culminating in the 2021 publication of the book The Vertical Diet, which formalized its principles for broader application in . This progression marked Efferding's shift from athlete-coach to innovator, addressing the limitations of traditional high-volume diets that often led to gastrointestinal distress in strength sports.

Core Principles and Applications

The Vertical Diet, developed by Stan Efferding to address his own needs as a competitive powerlifter, centers on a structured framework that prioritizes easily digestible, nutrient-dense foods to optimize nutrient absorption, gut health, and athletic performance. At its core, the diet divides foods into "vertical" and "horizontal" categories, primarily deriving calories from vertical foods—such as red meat (e.g., beef or bison for high-quality protein and micronutrients like iron and B vitamins) and white rice (for readily available carbohydrates)—which are selected for their low fiber content and minimal antinutrients to facilitate quick digestion and reduce gastrointestinal distress, supplemented by horizontal foods including low-FODMAP vegetables like spinach, carrots, and red peppers, as well as potatoes, sweet potatoes, and select fruits (e.g., oranges or blueberries), to provide essential micronutrients without compromising gut tolerance. This selective approach avoids high-FODMAP items such as onions, garlic, broccoli, beans, and processed grains, aiming to minimize bloating and enhance overall digestive efficiency. A key rule of the Vertical Diet is maintaining a high-calorie surplus tailored to the individual's (BMR) and training demands, particularly for strength athletes seeking muscle gain and weight increase, with protein intake targeted at about 1 gram per pound of body weight, fats at 0.3 grams per pound, and carbohydrates filling the rest to fuel intense sessions. This emphasis on gut health stems from the diet's low-FODMAP foundation, aiming to alleviate gastrointestinal symptoms by reducing fermentable carbohydrates that can disrupt digestion. For powerlifters and bodybuilders, the benefits include sustained energy levels from stable blood sugar provided by simple carbs, faster recovery due to improved nutrient uptake, and reduced that allows for consistent training volume without digestive interruptions. Sample meal structures follow a straightforward pattern to ensure compliance and convenience, typically consisting of 4-6 meals per day structured around vertical staples. For instance, a standard meal might feature 8-12 ounces of lean (like sirloin) paired with 1-2 cups of cooked , seasoned simply with salt and butter, accompanied by a small serving of horizontal foods such as steamed or a for added and vitamins. Snacks could include full-fat Greek yogurt with low-FODMAP fruits or eggs with cheese and carrots, emphasizing portion increases ("") as appetite grows to support in training. These meals are designed to be preppable in advance, promoting adherence among busy athletes. The diet's applications extend beyond bulking, with adaptations for various goals through phased implementation: an initial 4-6 week elimination phase strictly limits variety to reset digestion, followed by testing and personalization to reintroduce tolerated foods. For fat loss, calorie intake is reduced while maintaining high protein to preserve muscle, whereas adaptations might incorporate more horizontal carbs like juices for quicker energy without gut overload. However, it is positioned as a short-term tool rather than a lifelong regimen, with recommendations to monitor for potential gaps from limited variety.
