About ThinFastMD
What is ThinFastMD?
ThinFastMD is a physician-led medical weight loss practice with four clinics in Illinois, in Hinsdale, Arlington Heights, Brookfield and Rockford. It has offered medical weight loss since 1984 and says it serves patients across the Chicago suburbs and Rockford. It names Dr. Ehtesham Ghani as its medical director and founder. It has a 4.7 rating on Google from 38 reviews.
It offers GLP-1 semaglutide, weight loss injections, OPTIFAST and OptitrimMD meal replacement, prescription appetite suppressants, wellness and vitamin injections, medical monitoring, and programs for adolescents and for patients before or after bariatric surgery. The medications it names are semaglutide, Wegovy, Ozempic, tirzepatide, Zepbound, Mounjaro, phentermine, phendimetrazine, diethylpropion and metformin. It is open Monday to Friday, 8am to 5pm, and closed on weekends.
Its men's program begins with an in-person physician exam. It also offers telehealth. In its own words: "We also offer telehealth and online consults for follow-up convenience, plus options for men who prefer to start remotely."
This listing is for its Hinsdale office at 120 E. Ogden Avenue, Suite 120.
What does it cost?
The new patient visit is $159. That covers the consultation, physical exam, vitals, an in-office EKG and baseline lab work in one visit. It is a self-pay offer, so no insurance is required, and it is not billed to insurance. It is available to new patients age 18 and over, the certificate is valid for 30 days from issue, and it is not available to Medicare, Medicaid or other federal healthcare program beneficiaries.
Medication, meal-replacement products and ongoing program fees are not included in the $159. It does not publish prices for medication or the ongoing program. It also does not say whether insurance is accepted for ongoing care.
What should you ask before you book?
Ask who signs the prescription. It names Dr. Ghani as medical director, but it does not say which of its physicians prescribe at each clinic.
Ask whether the monthly program fee includes medication, and what the full program costs. Ask whether the medication is brand-name or compounded. It names Wegovy, Ozempic, Zepbound and Mounjaro, but it does not say whether any medication is compounded.
Ask what follow-up visits and lab work cost, and whether any of that is covered by insurance. Ask how a program is cancelled and whether there is a membership term. It does not publish cancellation terms.
If you want to start remotely, ask which states its telehealth serves. It does not say.
Who is it a good fit for?
This is a good fit if you want physician-supervised weight loss care that starts with an in-person exam, you are ready to pay cash for the visit and any medication, and you live near Hinsdale, Arlington Heights, Brookfield or Rockford. It may not suit you if you need the full price before booking or need insurance to cover ongoing care, since neither is published. Call (708) 485-4050 to ask the questions above before you book.
