Field notes

A short, honest read on what the evidence means now.

These are not exhaustive reviews. They are decision-oriented translations with the signal and the uncertainty kept in the same frame.

01Emerging obesity medications

GLP-1 & the new energy-balance era

What nutrition becomes when medicines take on energy balance.

Read field note 02Ultra-processed foods

Beyond the dogma on UPF

From category-level concern to testable mechanisms and defensible guidance.

Read field note 03Personalized & precision nutrition

Where foods, devices & AI converge

Turning individual variation into decisions without turning noise into certainty.

An occasional letter from Robert on a paper, argument, or change in the landscape that deserves a slower and more careful read.
