Hard-Boiled Eggs

Hard-boiled eggs remain the most nutritionally complete single-food snack, delivering 6.3 grams of complete protein per large egg (50 grams) with all nine essential amino acids. Two eggs provide 12.6 grams of protein for 154 calories and zero carbohydrates, offering a superior amino acid profile that surpasses every other single whole food on this list. The biological value protein score, the highest among commonly eaten foods, cements eggs as an anchor for any serious protein strategy. Each egg supplies 25% of the daily value for choline—critical for brain and liver health, yet over 90% of Americans fall short. Lutein and zeaxanthin protect against age-related macular degeneration, and selenium, riboflavin, and vitamin D round out the package. For GLP-1 users targeting 25–40 grams per snack, three to four eggs (18.9–25.2 grams) remain among the cheapest protein sources available.
