Measurable Outcomes
Related Protocols
Fiber Target (30-50g/day)
Aim for 30-50g fiber daily from diverse plant sources. Feeds gut microbiome, improves metabolic health, and is strongly linked to lower mortality risk.
Protein Target (1.6-2.2g/kg)
Hit 1.6-2.2g protein per kg bodyweight daily across 3-5 meals. The single most important nutritional target for muscle preservation, satiety, and healthy aging.
Fermented Foods for Gut Health
2-3 servings of fermented foods daily to boost gut microbiome diversity. Stanford research showed this increased microbial diversity and reduced inflammatory markers.
Ultra-Processed Food Swap
Replace one daily ultra-processed anchor food with a minimally processed alternative you still enjoy.
