Protein First: How Meal Sequence Flattens the Post-Meal Curve

Eating protein and fiber before carbohydrates measurably lowers the glucose spike from the same meal. The order of your plate is a free intervention.

One of the most reliable findings in continuous glucose data is also one of the easiest to act on: the order in which you eat a meal changes the spike it produces.

Same meal, smaller spike

When protein and fiber come before the starch, the carbohydrate is absorbed more slowly. The result is a flatter, lower glucose curve from an otherwise identical plate.

  • Protein/fiber-first meals produced lower peak glucose
  • The post-meal curve was flatter and returned to baseline sooner
  • No change in calories or ingredients required
The cheapest metabolic intervention is free: eat the salad and the protein first.

Built into the app

HealthOS scores each meal against your real response and suggests small, concrete swaps — more protein, more fiber, a different order — rather than another wall of numbers.
