About Slowing the Clock
A practical health guide built on established research in longevity, fitness, and metabolic health. We translate evidence-based information into clear, honest guidance — designed to help you make informed decisions about your health. Written to inform, not to steer.
What's inside the guide
13 chapters covering everything you need to make a confident decision
How GLP-1 actually works — and why most people misunderstand it
The mechanism behind the drug, what it genuinely changes about hunger and appetite — and what it doesn't touch.
Chapters 1 & 2 — in plain English, no jargon
How much weight you can realistically expect to lose
Clinical ranges, realistic timelines, and why the dramatic transformations you've seen online aren't the norm.
Chapter 4 — the numbers behind the decision
Side effects, risks and what doesn't always come up in clinic consultations
The common ones, the less common ones, and the questions worth asking before you commit to anything.
Chapter 7 — what clinics don't always mention upfront
What happens when you stop — and why most people don't think about this until it's too late
The question nobody asks upfront — and why the answer should shape your decision from the very start.
Chapter 10 — the part most guides leave out
Most people wish they were better informed before they started.
This is that guide.
