Bryan Johnson's zero-added-sugar approach
Bryan Johnson's journey from a self-proclaimed "destroyed" body to a hyper-optimized longevity enthusiast is well-documented. A cornerstone of this transformation, and his Blueprint protocol, is the complete elimination of added sugars. For Johnson, sugar is viewed as a source of high caloric value with minimal nutritional benefits, representing an "evil food" that creates a metabolic rollercoaster. His intense focus on reversing biological aging and achieving optimal health biomarkers leaves no room for empty calories or metabolic disruptions.
His diet, which is strictly vegan by choice (except for collagen peptides), is entirely composed of whole, unprocessed plant-based foods. The Blueprint protocol dictates a precise caloric intake and macronutrient distribution, meticulously measured and monitored by his team of doctors. The goal is to nourish every organ in his body optimally, and added sugar does not fit into this highly controlled and data-driven regimen. This strict control is a major shift from his past lifestyle, where high sugar intake contributed to weight gain, depression, and poor sleep.
The types of sugar Bryan Johnson avoids
To achieve his goal of zero added sugar, Johnson has cut out several common sugar sources from his diet. His avoidance extends beyond just table sugar and includes other processed forms that disrupt metabolic health. The list of avoided items includes:
- White and brown sugar: He has explicitly stated his avoidance of these common processed sugars due to their high caloric value and lack of nutrients.
- High-fructose corn syrup (HFCS): He specifically avoids HFCS because it is known to increase uric acid, which is detrimental to his health goals.
- Junk food: Most junk foods are loaded with sugar and other processed ingredients, and he views them as addictive and harmful.
- Alcohol: Although not a sugar, he also eliminated alcohol, noting it was too "expensive" from a caloric and metabolic perspective.
How Johnson gets his sweetness
While avoiding added sugars, Johnson does not completely eliminate sweetness from his diet. Instead, he sources it naturally and employs carefully selected alternatives. His daily diet includes berries and pomegranate juice, which provide natural fructose along with a high concentration of antioxidants and vitamins. For other applications, such as his protein powders or other needs, he utilizes approved sweeteners. This highlights his methodical and data-driven approach to even minor aspects of his nutrition.
Johnson's approved sugar alternatives include:
- Trehalose: A naturally occurring sugar used as an alternative.
- Monk Fruit: A natural, zero-calorie sweetener.
- Xylitol: A sugar alcohol often used as a sugar substitute.
- Allulose: A rare sugar that provides sweetness with minimal impact on blood glucose.
This nuanced approach allows him to enjoy the taste of sweetness without the negative metabolic consequences associated with added sugars. His attention to detail even extends to his oral hygiene, where he recommends reducing sugar intake to protect teeth.
Comparison of past vs. present sugar intake
To understand the dramatic shift in Bryan Johnson's diet, a comparison of his sugar intake from childhood to his current Blueprint protocol is revealing.
| Aspect | Bryan Johnson (Childhood) | Bryan Johnson (Blueprint Protocol) |
|---|---|---|
| Daily Sugar Intake | Approximately 100-150 grams per day | Zero added sugar |
| Sources of Sugar | Sugary cereals, sodas, and other processed junk foods | Natural fructose from berries and fruits |
| Use of Sweeteners | None, relied on processed sugar | Uses specific, controlled alternatives like monk fruit and allulose |
| Dietary Philosophy | Uncontrolled consumption based on convenience | Data-driven, biomarker-optimized, and purpose-built for longevity |
| Metabolic Impact | Significant fluctuations in blood glucose and other negative health effects | Stabilized blood glucose levels, with Johnson reporting blood glucose control better than 98% of 18-25 year olds |
Blood glucose control and Blueprint
For Johnson, the elimination of added sugar is not just about avoiding empty calories; it's a strategic move to optimize his blood glucose. He publicly shares his blood glucose data, showing significant improvements and control within the top percentile for young adults. His protocol also includes prescription medications like Metformin ER and Acarbose, which are used to control blood sugar levels. This aggressive, medically supervised approach underscores his commitment to managing this "master signal of vitality".

Conclusion: A complete dietary overhaul
Bryan Johnson's approach to sugar is emblematic of his entire Blueprint protocol: an extreme, data-driven optimization aimed at longevity. He has gone from a high-sugar, high-processed food diet in his youth to a completely zero-added-sugar regimen in his pursuit of biological age reversal. The sweetness he consumes now comes from nutrient-dense, natural sources and controlled, researched alternatives. His successful management of blood glucose levels is a key metric in his project, proving that a disciplined approach can yield significant results. While his lifestyle is not easily replicated, his strict avoidance of added sugar highlights a critical component of maximizing health and longevity for anyone seeking to improve their diet.
