Lose the fat.Get the body you
actually want.
We analyse your body composition, then build a plan to strip fat while keeping the muscle you’ve earned, designed specifically for you.
WHAT YOU’RE ACTUALLY BUYING
You’re not buying a diet. You’re buying a different life.
Getting lean isn't just about looking good in a mirror. A leaner, stronger physique changes how you look, how you feel, and how the world responds to you. Here's what you're actually buying:
- Look better in clothes - and out of them
- Walk into any room with quiet confidence
- More strength and more energy, every single day
- Protect your long-term health
- Add measurable years to your life (the research is below)

What is KEPT Lab?
KEPT Lab gives you a personalised body-composition analysis and a recomposition plan built around your unique frame, age, and goals. The aim is simple: lose fat while keeping the strength and muscle you've built, without drugs or crash diets.
Who is this for?
Anyone who wants to lose fat for their health or how they look and is tired of generic, one-size-fits-all plans. Whether you're just starting or already training, we build the plan around your current composition and where you want to get to.
What exactly will I receive?
A detailed breakdown of your current body composition, a realistic before-and-after of your potential, and a step-by-step recomposition plan covering training, nutrition targets, and how to track your progress.
How accurate is the analysis?
We combine your photos, measurements, and inputs with composition models and human review to estimate your body-fat range, muscle distribution, and frame. It isn't a clinical DEXA scan, but it's accurate enough to build and adjust a plan that genuinely works.
What do you actually measure?
Your body-fat range, lean-mass distribution, your frame and somatotype, and key proportions, plus how your metabolism and habits factor in. Together these set realistic targets for your recomposition.
Do I need a gym, DEXA scan, or special equipment?
No. Everything is done from home using a few photos and simple measurements. No DEXA, no InBody machine, and no gym membership required to get your analysis.
What does the recomposition plan include?
Your training approach to preserve strength while losing fat, a daily protein floor and calorie target, and a week-by-week structure so you always know your next step.
Is the plan actually tailored to me?
Yes. Two people at the same weight can need completely different plans. Yours is built from your composition, training history, schedule, and goals, never a generic template.
Do I have to follow a strict diet?
No extreme cuts and no banned foods. We set a protein floor and a sensible calorie target you can hit with food you actually eat, so the plan is something you can stick to.
How do I get started?
Start your plan, enter a few details, and submit your photos and measurements. We handle the analysis and send your breakdown and plan back, all without you leaving home.
How long until I get my analysis?
Your analysis and plan are typically ready within a few days of submitting everything we need.
Can I use this alongside my current training?
Absolutely. If you already lift or run, we build around it, adjusting your volume and nutrition so you keep your strength while the fat comes off.
How much does it cost?
It's $97 per year, one membership covering your analysis and plan, with no hidden fees.
Is it a one-time fee or a subscription?
It's a yearly membership at $97/year, and you can cancel anytime.
What if it isn't right for me?
If the plan isn't a fit, reach out to our team and we'll make it right. We'd rather you be happy than locked in.
Is my data private and secure?
Yes. Your photos, measurements, and results are private to you, handled securely, and used only to build and refine your plan.
What happens to my photos?
They're used solely for your analysis. We don't sell them, publish them, or share them with third parties.
Do you share my information?
Never. Your information is never sold or shared. It stays between you and our team.
Will tracking my body make me obsessive?
Most obsession comes from not knowing where you stand. Clear numbers and a real plan usually do the opposite, replacing guesswork and anxiety with direction.
Why focus on body composition instead of the scale?
The scale can't tell fat from muscle. Two people at the same weight can look and feel completely different. Composition is what actually changes how you look and perform.
Why does keeping my strength matter so much?
Losing fat by also losing muscle leaves you smaller and weaker, not leaner. Our entire approach is built to strip fat while protecting the strength you've earned.
Why not just take Ozempic?
GLP-1s can drop weight, but a large share of that is muscle, and it often returns once you stop. We focus on a sustainable change in composition that holds without a prescription.
Can I really get results without drugs?
Yes. The fundamentals, enough protein, smart training, and a manageable deficit, work. Our job is to make them specific to you and easy to follow.
What if I have a lot of fat to lose, or only a little?
The plan scales either way. Whether it's your first 30 pounds or the last stubborn 10, the targets and pacing are set to your starting point.
Can I talk to a real person?
Yes. Our care team is reachable from your dashboard and by email at hello@keptlab.com whenever you get stuck or have questions.
What if I get stuck on my plan?
Message us. We'll help you troubleshoot and adjust so a tough week doesn't derail your progress.
How often can I update my plan?
As your body changes, resubmit your photos and we'll refresh your analysis and adjust your targets so the plan keeps pace with you.
