What is weight loss?
Body weight reflects a long conversation between your brain, gut, fat tissue and muscles. Hormones signal when you are hungry and when you have had enough. Your brain weighs those signals against your energy stores, mood and routine. Fat cells store energy and release it when needed. This system is designed to protect you, which is why weight can feel stubborn to change.
How your genes play a role
Many of the genes linked to body weight act in the brain, influencing appetite, cravings and satiety. Others shape leptin signaling or how fat is stored and released. Each variant usually has a small effect, and together they create tendencies rather than fixed outcomes. Sleep, stress, food environment and movement still have a meaningful influence.
Understanding your genetic tendencies can bring kindness to a topic that often carries blame. If you are more inclined toward strong hunger signals, for example, that knowledge may help you plan meals that keep you satisfied. Insight like this can guide more realistic expectations and better conversations with your clinician or dietitian. The aim is not a perfect number, but an approach that respects how your body works.

Genes we analyze
| Gene | Role |
|---|---|
| FTO | One of the most studied genes in body weight, linked to appetite and food intake. |
| MC4R | Encodes a brain receptor that helps regulate hunger and energy balance. |
| BDNF | Produces a brain growth factor that also plays a role in appetite regulation. |
| LEPR | Makes the receptor that allows the brain to respond to leptin from fat tissue. |
| PLIN | Codes for perilipin, a protein that coats fat droplets and controls how fat is released. |
Full panel: 14 genes
MC4R, FTO, TMEM18, SEC16B, NEGR1, GNPDA2, ATXN2L, SH2B1, BDNF, LEP, LEPR, PLIN, PPM1K, SLC39A8
Putting results to use
Many people use their results as a starting point for conversations with their clinician about:
Many people find that protein and fiber help them feel full for longer.
Activity that feels good is often easier to keep up than intense short-term plans.
Short sleep is linked to changes in appetite hormones, so rest is often part of the conversation.
Noticing stress-related eating can be a gentle first step toward steadier habits.
Questions
Do my genes mean I cannot lose weight?
No. Genes influence tendencies, not destiny. Many people with variants linked to higher weight still respond well to changes in eating, activity and sleep.
Is there a single weight gene?
No. Body weight is influenced by many genes, each with a small effect, along with environment and lifestyle.
How should I use these results?
Treat them as context. Sharing them with a clinician or dietitian can help shape an approach that suits your appetite and routine.
