The tale of two Da Vinci diets
Understanding the term 'Da Vinci diet' requires differentiating between two distinct concepts. The first is a set of mindful, mostly vegetarian eating principles derived from the habits and notes of the Renaissance polymath Leonardo da Vinci. The second is a commercial diet plan created in the mid-2000s by a baker named Stephen Lanzalotta, who borrowed the name for a diet based on the mathematical Golden Ratio. These two approaches are vastly different in their origins and core principles.
The Historical Da Vinci Diet: A Renaissance approach to mindful eating
Derived from historical documents, personal letters, and notes, the eating habits of Leonardo da Vinci reflect a philosophy of balance, simplicity, and reverence for nature. His diet was remarkably modern in its principles, focusing on the quality of food and the experience of eating.
Key principles
- Moderation: Da Vinci's writings stress avoiding excess. In the Codex Atlanticus, he advises, "do not eat if you are not hungry" and suggests a light evening meal. This focus on portion control and listening to the body's natural signals is a cornerstone of his approach.
- Simplicity and Freshness: He favored simple, well-cooked ingredients that were as close to their natural state as possible. His diet largely consisted of fresh, seasonal, and fiber-rich foods.
- Mindful Eating: More than just what to eat, Da Vinci encouraged savouring the smell, taste, and texture of food. This emphasis on mindful dining promotes better digestion and a deeper appreciation for the meal.
- Vegetarian Focus: While there is some debate among historians about whether he was a strict vegetarian or a pescetarian who occasionally ate fish, it is widely agreed that his diet was heavily plant-based. Accounts from contemporaries describe him as a vegetarian, possibly influenced by his love and respect for animals. His favorite dish was reportedly minestrone soup, a clear vegetarian staple.
- Hydration: Da Vinci recognized the importance of water for health, and his diet encouraged drinking plenty of fluids, especially water or vegetable juices.
A note on controversy
Some academic discussions, while purely speculative, have raised questions about potential health effects related to Da Vinci's long-term vegetarianism. One report hypothesized that his later-life stroke could have been influenced by increased homocysteine levels associated with a long-term plant-based diet, though this is not a definitive conclusion. It is crucial to remember that nutritional science and food availability in the 15th century were drastically different from today's.
The Modern Da Vinci Diet: A Golden Ratio blueprint
In the mid-2000s, baker Stephen Lanzalotta created and trademarked a diet plan capitalizing on the popularity of the novel The Da Vinci Code. His plan is based on the idea that the Golden Ratio, a mathematical value famously used by Da Vinci in his art, holds the secret to optimal health and weight loss.
Key principles
- The Golden Ratio (1:2:3): Lanzalotta’s diet suggests meals should follow a specific ratio: 1 part grain, 2 parts protein, and 3 parts vegetables/fruit.
- Mediterranean-Style Foods: The plan incorporates Mediterranean-style foods, including bread, fish, cheese, vegetables, nuts, and even a moderate amount of wine.
- Promotes Carbohydrates: The diet was explicitly created in opposition to the low-carb trend popularized by diets like Atkins at the time, arguing for the inclusion of bread and other carbohydrates.
- Marketed for Weight Loss: The plan was promoted as a weight-loss secret, using the allure of the Da Vinci name to attract followers.
It is important to note that the scientific link between the Golden Ratio and metabolic weight loss, as claimed by Lanzalotta, is minimal and not supported by mainstream nutritional science. The diet's health benefits, if any, likely stem from its emphasis on whole foods and vegetables, echoing the principles of the Mediterranean diet.
Comparing the two Da Vinci diets
| Feature | Historical Da Vinci Diet | Modern Lanzalotta Diet |
|---|---|---|
| Origin | Derived from Leonardo da Vinci's historical notes and personal habits. | Created by baker Stephen Lanzalotta and trademarked in the mid-2000s. |
| Core Philosophy | Mindful eating, moderation, and simplicity. | Mathematical Golden Ratio for macronutrient balancing. |
| Food Focus | Primarily fresh, whole, fiber-rich, and vegetarian foods. | Mediterranean-style foods based on a 1:2:3 ratio of grains, protein, and vegetables. |
| Dietary Restrictions | Avoided excess sugar, salt, and fat. Minimal meat consumption, if any. | Bans processed foods, fried foods, and sugary drinks in the early phase. |
| Weight Loss Goal | Not a dedicated weight-loss diet, but a healthy lifestyle approach. | Explicitly marketed for weight loss. |
| Scientific Basis | Principles align with modern recommendations (mindful eating, whole foods). | The Golden Ratio principle for weight loss is not scientifically validated. |
Adopting a Da Vinci-inspired approach today
While the modern diet is a commercial product with little scientific backing for its core premise, the historical principles of Leonardo da Vinci offer a timeless and effective framework for healthy eating. To follow a truly 'Da Vinci-inspired' diet today, you should focus on the following:
- Prioritize whole foods: Base your meals on fresh fruits, vegetables, whole grains, and lean proteins, avoiding highly processed or sugary items.
- Embrace mindfulness: Eat slowly, chew your food well, and pay attention to your body's signals of hunger and fullness. Make every meal an experience to be savored.
- Practice moderation: Avoid overeating and favor lighter meals, particularly in the evening.
- Stay hydrated: Drink plenty of water throughout the day to support cognitive function and overall health.
- Lean towards plant-based meals: While not necessarily requiring strict vegetarianism, incorporating more fiber-rich, plant-based foods can offer significant health benefits.

Conclusion: A timeless lesson in balanced nutrition
In summary, the concept of what is the Da Vinci diet? leads to two very different answers. The historical interpretation is not a rigid diet plan but a philosophy of eating rooted in moderation, mindfulness, and a predominantly plant-based approach, which aligns closely with modern healthy eating recommendations. In contrast, the modern diet is a commercially branded product with a tenuous connection to Leonardo's work, relying on a mathematically dubious premise. For those seeking genuine guidance, Leonardo's timeless wisdom of simple, fresh foods and mindful consumption offers a far more valuable and sustainable path to a healthier life.
