Metabolic Myths
Evidence over noise

Metabolic health, separated from the misinformation.

Insulin resistance, blood sugar, GLP-1 medications, metabolic syndrome — there's a flood of confident, contradictory advice out there. We trace each claim back to the peer-reviewed research and tell you what the evidence actually supports.

Sourced, and labelled

We name every source, and we tell you what kind of evidence it is — a trial, an observation, or a mechanism in mice.

We show the disagreement

Where the science is genuinely contested, we say so — and explain what's settled versus what's still being argued.

Plain language, no hype

Written to inform a decision, not to sell a supplement or a fear. We tell you what the evidence means for you.

What we cover

Four areas where the gap between the research and the advice is widest. Answers are published as we finish them.

Insulin Resistance

What it is, how it's actually measured, and which interventions hold up.

Blood Sugar & CGMs

Glucose spikes, continuous monitors, and what the data does and doesn't tell you.

GLP-1 Medications

Semaglutide, tirzepatide and the rest — benefits, risks, and the open questions.

Metabolic Syndrome

The cluster of risk factors, the real numbers, and what moves them.

Myth, examined
“Eating late at night ruins your metabolism.”
No — but it does make you hungrier

Two randomised trials published on the same day, in the same journal, appear to disagree. Read together they settle it: the same calories don't count for more after dark, but a late schedule leaves you hungrier, and that is how it gets you. Night shift workers are the exception.

The evidence we weighed

1Vujović et al., Cell Metabolism 2022 — same meals, four hours later: hunger up, energy expenditure down.
2Ruddick-Collins et al., Cell Metabolism 2022 — calories moved around the day: no difference in weight lost.
3Xie et al., BMC Endocrine Disorders 2024 — why night shift workers are a separate case.

We publish our rules so you can hold us to them.
