Peter Attia's Association with David Bars: The Primary Recommendation
The most direct and prominent answer to the question of which protein bars Peter Attia recommends is the David Bar. Attia holds the title of Chief Science Officer for the brand, a position that gives his endorsement significant weight in the biohacking and health-conscious community. The product's marketing heavily features Attia and his podcast colleague, Andrew Huberman, positioning it as an optimized nutritional tool.
The appeal of the David Bar lies in its exceptional macronutrient profile. Each bar is engineered to contain a significant amount of protein (28 grams) for a relatively low caloric count (150 calories), while also being sugar-free. This fits squarely within Attia's nutritional philosophy, which prioritizes high protein intake for muscle maintenance and overall health, especially as one ages. The protein-to-calorie ratio is designed to be highly efficient, making it a convenient way to meet daily protein targets without excess calories.
The Role of EPG in David Bars
An interesting and debated aspect of the David Bar is its use of a unique ingredient: esterified propoxylated glycerol, or EPG. This modified plant fat is mostly undigested by the body, allowing the bar to achieve a low-calorie count despite having a satisfying mouthfeel. This technological approach to calorie reduction is a key feature of the bar, though it has drawn some criticism from those who prefer less-processed, whole-food ingredients.
The Nutritional Philosophy Behind Attia's Choices
Beyond a single product endorsement, Attia's recommendation stems from a broader nutritional framework that emphasizes several key pillars of health and longevity. Understanding these principles provides a deeper insight into his preference for bars like David's.
- Prioritizing High Protein Intake: Attia is a vocal advocate for higher protein consumption than the standard Recommended Dietary Allowance (RDA). He suggests aiming for around one gram of protein per pound of body weight for active individuals to support muscle mass, which he considers a critical indicator of long-term health. Protein bars serve as a practical tool for individuals to hit these high daily targets, particularly on busy days.
- Focusing on Protein Quality: The type of protein is also important. Attia emphasizes high-quality sources rich in essential amino acids. Animal-based proteins like whey and casein are particularly valued for their bioavailability and ability to stimulate muscle protein synthesis effectively. This is why he favors whey isolate in his protein powder and protein bars that use a similar quality protein system.
- Monitoring Caloric Intake: While protein is paramount, Attia also believes in managing overall caloric intake to maintain a healthy body composition. Bars that provide a high protein dose with minimal excess calories, like the David Bar, align with this goal by helping to control overall energy balance.
- Avoiding Refined Sugars and Junk Food: A cornerstone of Attia's nutrition is the elimination of highly processed foods, refined sugars, and excessive fructose. Protein bars that are low in sugar or use alternative sweeteners fit into this guideline, in contrast to many conventional snack bars loaded with sugar and corn syrup.
Comparison of Protein Bars Endorsed by Peter Attia and Others
| Feature | David Bar (Attia's Endorsement) | Quest Bar (Honorable Mention) | RXBar (Whole-food alternative) |
|---|---|---|---|
| Protein (per bar) | 28g | High protein (varies by flavor) | 12g (average) |
| Calories (per bar) | 150 kcal | ~200 kcal | ~210 kcal |
| Sugar | 0g | 1g (some flavors) | High, from dates |
| Key Ingredients | Whey, egg white, EPG fat, artificial sweeteners | Milk protein isolate, whey, fiber, erythritol | Dates, egg whites, nuts |
| Processing Level | Ultra-processed | Processed | Minimally processed |
| Primary Benefit | Maximum protein-to-calorie ratio | Balance of protein, calories, and fiber | Clean, whole-food ingredients |
Other Considerations and Perspectives
While the David Bar is the most direct recommendation, Attia's broader principles can lead to the consideration of other options. In an informal analysis, Quest Bars have received an honorable mention for their high protein-to-calorie ratio and fiber content. However, it is the underlying nutritional principles that matter most, not just a specific brand.
It is also essential to consider the opposing viewpoints regarding highly processed protein bars. Critics argue that bars using synthetic fats like EPG and artificial sweeteners, as seen in David Bars, are a departure from whole-food nutrition and may have unforeseen health effects. A more conservative approach, championed by some longevity experts, might favor less-processed options, even if they have slightly less efficient macronutrient profiles.
Conclusion: Making Informed Protein Bar Choices
Ultimately, the choice of protein bar depends on an individual's specific needs, dietary priorities, and comfort with processed ingredients. For those seeking maximum protein efficiency in a low-calorie, zero-sugar format, the David Bar is a direct recommendation from Peter Attia. However, his broader nutritional framework highlights the importance of high-quality protein, a priority that can be met through a variety of products or whole foods. Regardless of the brand, the takeaway from Attia's approach is to use protein bars strategically as a convenient way to boost your overall protein intake while minimizing junk food and excess calories. Always prioritize whole-food protein sources when possible, and evaluate supplemental options based on their ingredient quality, macronutrient profile, and overall alignment with your health goals.

A Quick Guide to Choosing a Protein Bar
- Evaluate the Protein-to-Calorie Ratio: The goal is to maximize protein intake relative to calories. Opt for bars with a high protein percentage to meet your daily targets efficiently.
- Prioritize High-Quality Protein: Look for ingredients like whey isolate, egg white protein, or other sources with a high Protein Digestibility Corrected Amino Acid Score (PDCAAS).
- Check Sugar Content: Avoid bars with high amounts of added sugar, corn syrup, or other sweeteners. Low-sugar or zero-sugar options are preferred.
- Consider Ingredient Processing: Decide whether you prefer a minimally processed, whole-food bar or are comfortable with highly engineered, low-calorie ingredients like EPG.
- Match to Your Goals: Choose a bar that fits your specific needs, whether it's a post-workout recovery snack (higher carbs acceptable) or a low-calorie protein boost (David Bar style).
