About Doc's Diet
What is Doc's Diet?
Doc's Diet is a cash-pay medical weight loss practice founded in 1999 by Daryl J. Wilkins, D.O., an osteopathic physician trained in internal medicine. Weight loss is the main work of the clinic. It offers a Personalized Care Program, weight management programs in California, and Vitamin B-12 injections, and it also sells vitamins and blood pressure cuffs. The clinic has offices in Linden, Turlock and Tracy.
The prescribers listed are Daryl J. Wilkins, D.O., and Bill Chapman, PA-C. The medication named is phentermine, a controlled prescription appetite suppressant. The clinic does not mention hormone therapy or peptide therapy. Google shows a 4.8 rating from 28 reviews. In its own words: "Your healthy weight is closer than you think."
What does it cost?
New patients pay $105 for the first month. Return patients pay $95 per visit. Each visit includes a focused examination, a Vitamin B-12 injection and phentermine, so the visit price includes the medication. Most patients come monthly, though it is not required. It accepts cash, debit and credit only, with no insurance or checks.
It is not clear whether the first-month $105 covers a different exam than the $95 return visits. The clinic does not publish membership terms or cancellation rules, so ask for both before you pay.
What should you ask before you book?
Ask which prescriber you will see, Dr. Wilkins or Bill Chapman, PA-C, and who signs your prescription. Ask whether the phentermine is brand-name or compounded, and which pharmacy fills it. Ask what lab work or follow-up costs beyond the visit price, and whether the clinic offers GLP-1 medicines such as semaglutide or tirzepatide.
Ask whether telehealth visits are available, since the clinic does not say. Ask which days each office is open, because the posted hours conflict. Ask how cancellation works and whether any fee applies if you stop coming.
Who is it a good fit for?
This is a good fit if you want an in-person, cash-pay visit with a physician or PA-C for medical weight loss, and you are comfortable paying for each visit yourself. If you need insurance billing, telehealth, or a medication other than phentermine, call and ask before you book.
