The scales aren’t moving.
You’re changing your habits, but your weight stays the same. It’s hard to stay motivated when your efforts seem to make no difference.

Your effort matters. Your appetite, metabolism and daily life matter too.
I’m making changes.
Cravings are hard to manage,
even when I’ve eaten.
The urge to eat returns, sometimes just after a meal. It occupies your thoughts and makes everyday choices harder.
I lose weight.
Then it comes back.
You’ve lost weight before, only to see it return. Feeling that you have to start all over again is discouraging.
I don’t want to spend
my life dieting.
Counting, weighing, avoiding certain foods… You want to lose weight without every meal becoming a restriction.
Your biology helps guide your next steps.
Your blood holds clues to how your body handles energy and fats. Explore them with four drops at home and reveal the invisible in you.

A few things to know.
Who is Weight Loss for?
For adults who want to understand their metabolic health and personalise food and activity choices for weight loss. The plan connects appetite, blood sugar, fat metabolism and muscle preservation. Explore our plans ↗
Do I need a biological twin before ordering?
No. You can get started with your kit. Your NutriCheck results enrich your twin alongside the personal information and existing results you choose to share.
How does the annual commitment work?
Optimal and Optimal Plus cover 12 months of Premium access. At the displayed monthly rates, the total commitment is €478.80 for Optimal or €1,078.80 for Optimal Plus. Your payment schedule is shown at checkout. Baseline includes three months of Premium with no subscription.
What is the difference between a complete test and a follow-up?
Your first complete test establishes a starting point. Follow-up tests focus on tracking changes and do not repeat the entire initial panel. They help your twin and guidance evolve with you. Members can buy follow-up tests separately for €49–€79, depending on the panel.
How does the molecular layer differ from the blood panel?
Your blood panel contains the named laboratory analyses shown above. Metabolomics, lipidomics and proteomics add complementary molecular information, including research-based insights. The pathways shown in the twin illustrate connections, rather than the complete list of tests.
Will this test tell me exactly how much weight I will lose?
No. Your results help personalise guidance and follow changes in your biology. Weight change depends on many factors, including habits, health, treatment and individual response. The plan does not guarantee a rate or amount of weight loss.
Does this replace medical care?
No. NutriCheck supports understanding and informed everyday choices. Discuss symptoms, treatments and medical decisions with your healthcare professional.
