## Summary

Field Notes / 13 slides NUTRITION What we know, what we don't.

Key sections include: Carbs, fats, protein — and the calorie controversy; Vitamins & minerals: deficiencies and limits; Calories in / calories out — with caveats; Blood sugar, insulin, and the metabolic narrative; Hyper-palatable, low-satiety — the dominant culprit?; The strongest evidence base in nutrition; Emerging evidence — less than once hyped; 1.2 – 2 g/kg for active adults; The new frontier — far from fully understood; Consensus on moderation — details contested.
