Mr. Age is AgeGen's editorial character. Facts come from the protocol above.

Ingredients (1 serving)

  • Canned tuna in water — 150 g
  • Egg, hard-boiled — 1 large
  • Green beans, blanched — 80 g
  • Cherry tomatoes — 80 g
  • Black olives — 20 g
  • Mixed greens — 60 g
  • Olive oil + Dijon — 1 tbsp

Macros per serving

  • Calories: 390 kcal
  • Protein: 38 g
  • Fat: 16 g
  • Carbs: 18 g
  • Fiber: 5 g

Key micronutrients

  • Omega-3 EPA+DHA: ~1.5 g
  • Selenium: ~90 µg
  • Vitamin D: ~80 IU
  • Potassium: ~700 mg

Why it earns a spot in the rotation

  • Marine omega-3 without cooking. Canned tuna delivers roughly 1.5 g of EPA+DHA in one serving — the long-chain omega-3s most diets under-supply — with no pan and no technique.
  • High protein, moderate calorie. 38 g of protein in 390 kcal makes this one of the higher protein-to-calorie lunches in the rotation.
  • Mediterranean pattern. Olives, tomatoes, green beans, and olive oil bring monounsaturated fat and polyphenols alongside the protein.
  • Fast and portable. Everything assembles cold in minutes and travels well in a container.
