Why we can make this promise
Built on your data, not guesswork.
We can guarantee a result because we actually measure it. Two scanners read your body and your food, the app builds your plan, and a real coach keeps you on it — answering your questions and adjusting the plan every week. Real data, real guidance, a real promise.

Your coach keeps you on track
They read your real numbers, answer your questions, and adjust your plan along the way — so you actually reach the goal.
Lower body fat in 100 days
Or your money back — and you keep both scanners.
Three streams of real data on you — body, food and activity — all read by a real coach. That's why the plan actually fits, and why we can stand behind the result.
Trusted by thousands of members.
A guarantee this bold only works if the system actually delivers. It does — here's the proof, from real customers and independent testing.
Works great and easy to use
Works really well and is easy to use through the app. The combination of the body scale and the food scale gives a great overview of where you stand and shows your improvements — plus good advice. Connected with Garmin, it's the perfect tool for losing weight and building muscle.
I LOVE their products!!!
I LOVE my products from Scanfit! I bought the bundle with the body scanner and food scale and use them every single day. Everything is collected in one place — weight, measurements, food and activity — which has genuinely saved me a lot of money on subscriptions. Can 100% recommend them! 🤩
Body Scanner and NutriScanner
A few days ago I received both my Body Scanner and NutriScanner Pro, and it lives up to everything that's promised. Super easy to set up and very user-friendly. I can warmly recommend both — whether you want to lose weight or simply follow your body composition.
Best purchase I've made in a long time
Best purchase I've made in a long time. Much better than all the weight-loss apps out there. It's simple and fast.
From the founder
"I put my coaches, my hardware, and my name behind this. If the system doesn't lower your body fat in 100 days, keeping your money would mean we didn't do our job. So you get all of it back — and you keep both scanners."
HansFounder, Scanfit
The numbers speak for themselves.
Here's what our members have achieved together with the system so far in 2026.
The only coaching that guarantees a result.
Most coaches work off what you tell them, and hope it works out. Ours work off your real, measured data — so the guidance is precise enough that we can put a guarantee behind it.
- Guides you from what you self-report
- No measured body-fat or food data
- Can't guarantee your result
- Guides you from measured body & food data
- Loses fat while keeping your muscle
- Lower body fat in 100 days — guaranteed
Most weight-loss coaching only tracks the scale. We track your muscle and body fat too — so your coach guides you to lose fat while keeping the muscle. Healthy loss, not just lower numbers.
The three data streams
Everything your coach sees about you.
Your body, your food and your activity — measured, not guessed. Together they give your coach the full picture.
The Body Scanner reads you
Body fat, muscle, visceral fat and 45 metrics — measured at 98% DEXA-grade accuracy. The number your guarantee is judged on.
The NutriScanner sees what you eat
Place your food on the scanner and it logs precise calories and macros in seconds — no guessing, no eyeballing portions.
Your workouts sync automatically
Connect Apple Health, Garmin or Health Connect and your steps and workouts flow in on their own — so the plan fits how you actually move.

A real coach reads it all — and tells you what to do next.
Body composition, food and activity all land in one place: with an experienced human coach. They look at your numbers, answer your questions, spot what's stalling, and adjust your plan — the real accountability that keeps you going.
Illustrative example of a weekly coach check-in. Your plan is built from your own data.
The deal, in plain English
If it doesn't work, you pay nothing.
We take all the risk. You keep the hardware either way.
All you have to do — and you don't have to be perfect:
Log ~90% of your meals. Not every bite, not perfection — just enough for your coach to guide you.
Eat the calories the plan gives you. A target calculated for your body — not a crash diet you have to white-knuckle.
Scan 3 times a week. A few seconds each time — that's how your coach tracks progress and the guarantee is measured, from day 0 to day 100.
A promise we can afford to make.
Thousands of members. 4.7 on Trustpilot. The system works — that's why we can stand behind it.

Questions, before you commit.
No. You need to log roughly 90% of your meals — enough for your coach to see the pattern. With the NutriScanner it takes seconds, and you don't have to be perfect. Real life happens; the plan is built to absorb it.
Yes — the coaching is what makes the guarantee possible. The scanners give the data and the app builds your plan; the coach reads your numbers, answers your questions, and adjusts the plan to keep you on track. Without a coach steering, there's no guarantee.
$266 today — $119 for the Body Scanner (NutriScanner free) plus 3 months of coaching upfront ($147). After that it's $49/mo, and you can cancel anytime, no contract. The 3 months upfront covers your full 100-day guarantee window.
If you followed the plan and your body fat isn't lower at day 100, you get a full refund of everything you paid — and you keep both scanners. There's nothing to trust: your numbers are measured, so we can't argue with the result. We just refund you.
You can still get a full refund — no hard feelings. The only difference is that since you did reach the goal, you'd send the scanners back. Either way, you're never stuck: don't hit the goal and you keep them; hit it and change your mind, just return them for your money back.
We only open a limited number of guarantee spots each month — 70 for July — so every member gets real coaching attention behind the guarantee. Once July's spots are filled, new sign-ups join the waitlist for the next month's opening.
100 days. A real coach. Zero risk to you.
Lower your body fat, or get every penny back and keep both scanners. The only thing you have to lose is the guesswork.
