Medical Weight Loss in Neenah, WI
Supervised, and out of pocket.
A clinical programme run by an Obesity Medicine Certified nurse practitioner — labs, dosing and review every eight weeks. Not a prescription handed over at a counter.

Be clear before you book
Two things people should know first.
We do not bill insurance.
Out of pocket only, for consultations, labs, medication management and follow-ups. No exceptions, and no surprise at the desk.
This is not body contouring.
Weight loss changes the number on the scale. Body contouring changes one treated area and leaves your weight alone. People book the wrong one, are disappointed, and do not come back — so we would rather say it here.
How the programme runs
Four stages, then a rhythm.
- 01
Consultation
History, goals, and whether this is the right programme for you at all. $50, credited to your account.
- 02
Labs & review
Bloodwork read before anything is prescribed, so dosing starts from your numbers rather than a protocol.
- 03
Your dose
Set for you and titrated deliberately. Starting low is what keeps side effects manageable.
- 04
Every 8 weeks
Weight, dose, side effects and what is actually happening between appointments.
The medication
Semaglutide, prescribed and monitored.
The GLP-1 most people arrive asking about by name. It has its own page because the questions about it are specific.
Common questions
Asked before starting.
Do you take insurance?
No. This programme is out of pocket only, and we say that plainly rather than at the end of a consultation. If insurance coverage is essential for you, a primary care route is the better starting point and we would rather you knew that before booking.
Do you accept insurance for medical weight loss?
No. Medical weight loss at Illumatox is out of pocket only — we do not accept or bill insurance for any part of it, including labs and follow-ups. It is worth knowing that before you book rather than after.
Is this just a prescription?
No, and a programme that is only a prescription tends not to hold. The medication is one part alongside nutrition and habit work, reviewed every eight weeks. What people keep after they stop is the part that was not pharmacological.
Who supervises the programme?
Kayla Lenzner, MSN, APNP, FNP-C, who is Obesity Medicine Certified. That certification is specific additional training in weight management, and it is the reason this is a clinical programme rather than a med-spa add-on.
Will body contouring do the same thing?
No, and confusing the two is the most expensive mistake people make here. Venus Bliss reduces fat in one treated area and tightens skin over it; it does not change your weight. Weight loss changes the number and not the contour. They solve different problems and are not substitutes.
How quickly will I lose weight?
Steadily rather than dramatically, which is the point — the reviews are every eight weeks because that is the timescale on which real change is visible and sustainable. Anyone promising a specific number by a specific date is guessing.
The other half
Protein and resistance training.
Rapid weight loss takes muscle with the fat, and muscle is what keeps metabolic rate up afterwards. This part is in the programme rather than mentioned at the end of it, because it decides whether the result holds.
