Built from 100 lbs of personal experience.
When Andrew Luu’s first son was born, he was 250 lbs, on three blood pressure medications, and facing a potential hypertensive emergency. A photo of himself holding his 6-day-old son hit him hard — he might not be around to watch his kid grow up. Something had to change.
As an engineer and project manager, Andrew dug into the root cause. The problem wasn’t willpower or laziness — it was a broken feedback loop. Our bodies are supposed to signal when we’ve eaten enough, but modern life breaks that signal. Fix the loop, and the weight takes care of itself.
He built a simple daily system: weigh in, let math cut through the noise of the scale, and get positive coaching every step of the way. Over three years he lost 100 lbs and kept it off — no strict diet, no gym routine. His transformation was so profound that he left his job to build Luuze, so anyone could do what he did.
Lose Weight Without the Frustration.
Weight naturally fluctuates by 2–5 lbs due to water, food, and hormones — none of which is actual fat.
Luuze uses a trend weight algorithm to cut through that noise and show you what’s really happening. It’s the same math-based insight that Andrew Luu used to lose over 100 lbs himself — and the reason he built Luuze: so anyone can do it, for free.
