Heart & Cardiovascular

Neutral Pathway
0/ 100

No direct primary biochemical modulation of heart health; pathway is neutral for Macro Meal Sequencing (Fiber First, Protein Second, Carbs Last).

Brain Longevity & Cognition

No direct primary biochemical modulation of brain longevity; pathway is neutral for Macro Meal Sequencing (Fiber First, Protein Second, Carbs Last).

Metabolic & Glycemic Health

Foundational Target (65-100)
89/ 100

Eating soluble and insoluble fiber first coats the duodenal mucosa in a viscous mesh, slowing carbohydrate diffusion; consuming protein and lipids next triggers cholecystokinin (CCK) and GLP-1 secretion to delay gastric emptying before carbohydrates reach the jejunum.
