Medical Weight Loss in Walnut Creek, Supervised Week by Week
Medical weight loss at Aesthetx Haus is a GLP-1 (tirzepatide) program run by Desirée Antonelli, MSN, FNP, a Family Nurse Practitioner with more than 15 years in healthcare. The weekly check-ins are complimentary. Nobody starts without a screening, and nobody is promised a number on the scale.
What medical weight loss looks like here
Wellness at Aesthetx Haus is medically supervised, which is a plain description rather than a slogan. Every plan starts with a consultation and a review of your medical history to confirm GLP-1 medication is appropriate for you. If it is not, your provider says so.
Once you start, you check in every week. That is where dosing gets adjusted, side effects get handled early, and the plan changes when your life does. The check-ins are complimentary, because a weight loss program without them is a prescription and a hope.

Weight loss reviews from Walnut Creek clients
"Desiree was amazing. I have been to several weight loss clinics and walked out not feeling like I got what I was looking for or talked out of what I really was interested in - but Desiree was very knowledgeable and walked me through the whole process step by step. I felt like I knew her my whole life."
"I have been working with Desiree for weight loss for about 3 months now and I can honestly say this was the best decision I have made with my healthcare. Desiree listened to the goals I had and advised on the best treatments for me. If you are looking for a provider that will really listen and help, Aesthetx Haus is the place to go."
"I originally went to a different med spa, but after a terrible experience, I came across her for a second opinion, and she has truly been a godsend. Desiree made me not lose hope, and I am so grateful to have found such a wonderful, trustworthy injector. What I really appreciate about her is her honesty."
Questions
Medical weight loss questions, answered
Still unsure? Book a consultation, and our team will answer anything this page does not.
How much does medical weight loss cost in Walnut Creek?
The cost of medical weight loss depends on whether you choose the GLP-1 program monthly or as a three-month package, and on anything you add, such as B12 or peptide therapy. Your provider gives you the exact cost at your consultation, before any treatment is booked, and the weekly check-ins are complimentary. Most GLP-1 prescriptions for weight loss are not covered by insurance, so plan on self-pay, and financing through Cherry is available.
What is GLP-1 and how does it work?
GLP-1 (glucagon-like peptide-1) medications like tirzepatide help regulate appetite, blood sugar and metabolism. They are prescribed as part of a supervised weight loss plan and given as a weekly injection.
How much weight can I expect to lose?
Results vary significantly with individual factors, adherence and lifestyle. We do not promise a specific outcome. We build a plan around your goals and support you toward them safely.
How long do I stay on the medication?
That is a decision made with your provider based on your goals, progress and response. Some clients use GLP-1 for a defined period. Others use it for longer-term maintenance.
Is medical weight loss covered by insurance?
Coverage varies by plan. Many GLP-1 prescriptions for weight loss are not covered and require self-pay. Cost and options are walked through at consultation.
What are the side effects?
Common ones are mild nausea, digestive changes and fatigue, especially when starting or increasing a dose. Weekly check-ins exist to catch and adjust for these. More serious side effects are rare and are discussed at consultation.
Do you accept new medical weight loss patients?
Yes. The first step is a consultation to confirm the program is right for you.
Can I finance medical weight loss?
Yes, through Cherry. A soft credit check shows the plans you qualify for without affecting your score, from interest-free payments to monthly installments up to 60 months.
