A coach that stays for the years after weight loss
LeKEEP by Oma Talk is ongoing coaching for self-regulation, for people keeping weight off after a programme or after stopping weight-loss medication. It is virtual care that continues at home after the clinic has done its part. It remembers what you said you would do, sees from your own scale and watch how it is going, and comes back at the moment that helps. Built with the clinicians who treat the problem.
A few months ago we talked about walking to the station a few times a week. How has that been going?
Slipped the last couple of weeks. I think I forget in the morning rush.
Fair enough, mornings are busy. Want me to ping you the next few days as a reminder?
Could you do it the evening before? Then I can plan for it.
Sure. I’ll check in tomorrow evening.
The perfect support is not always affordable at scale
After a weight-loss programme, and faster after stopping GLP-1 medication, most people regain. Sustained one-to-one coaching prevents it, and it costs one person’s time per person supported, every month, for years. So it gets rationed into a few intensive weeks and stops roughly when the long work starts. What is left is a leaflet, a discharge sheet and a number to call.

Coaching that adapts to the scale
Users talk to an avatar by video, with audio and chat as alternatives. A Bluetooth scale and a wearable supply weight, activity and sleep automatically, ambient monitoring that asks nothing of the person beyond stepping on the scale. Short optional questions cover appetite, mood, stress and motivation in the moment.
The coach starts conversations as well as answering them: check-ins, reminders, and a word when the scale has drifted over a longer period. Weekly cycles adapt on their own to what the data shows, for as long as the coaching is needed.
Weight is stable. The coach works on appraisal and on keeping what works.
A self-regulation cycle starts: a short weekly goal-setting session, and brief daily check-ins on planning and reflection.
The coach escalates, draws on what has worked for that person before, and signposts health care or community services.
Weekly regain, measured against baseline.
A real weekly appointment. An early word when the weight starts to creep. A coach who talks like a dietitian, not an app.
What keeps a conversation useful, month after month?
LeKEEP runs on the Oma Talk engine. Four parts of it do the work that a human coach would otherwise have to do from memory.
Nobody has to ask how the week went
Ambient monitoring: a Bluetooth scale and a wearable supply weight, activity and sleep. Short optional check-ins cover appetite, mood and stress in the moment.
A commitment made in March might make sense to talk about in June
Every conversation is parsed for what was agreed and what the person said they would do. It comes back when it is useful, which may be tomorrow or in two months.
The right conversation, at the right moment
A journey state machine tracks daily, weekly and monthly cycles and decides what the next conversation is about. What the person wants to talk about is still theirs to bring.
The part that proposes and the part that permits are separate
A control layer blocks, flags or passes every recommendation before anyone hears it. Review agents score each conversation for safety and fidelity to the evidence, and a person is brought in when one is needed.
Built with the people who treat the problem
The technology came out of a Copenhagen and Oxford research programme established in 2023 with a seed grant from the Novo Nordisk Foundation. Endocrinology, general practice, health economics, statistics and trial methodology are in the room.
In our own work, coaching people through each stage of the self-regulation cycle produced greater weight loss than self-weighing alone, in a standalone app with no in-person contact.
LeKEEP is evidenced the way digital therapeutics (DTx) are, on two tracks: a behavioural concept trial in adults recently stopping GLP-1 treatment, and supervised product pilots with real users. A randomised controlled trial follows once both have reported. The clinical research stays under university and hospital governance, so the product is evaluated by people with no commercial stake in the result.

As part of your service, extending your offering
LeKEEP is delivered through weight-management services as part of their home-based healthcare. It is a hybrid care model: the service keeps the relationship, LeKEEP supplies the ongoing coaching at home, and a staff dashboard hands a clinician the transcript and the data when something needs a human decision. Remote care operations get a patient in the home who is actually being followed.
Licensed through an API, on European infrastructure, built against the AI Act, GDPR and NIS2. LeKEEP never discusses medication, which keeps it clear of prescribing decisions.

Run a weight-management service?
We are looking for pilot partners in Denmark and the UK who see people finishing a programme or coming off medication, and who are building out their home-based and digitally enabled care. Backing the work rather than running a service? Write to us too.
