Clinic Profile

Ameri-Cal Weight Clinic is a weight loss center with multiple locations across the Bay Area in California, including Fremont.

The clinic focuses on medically supervised outpatient weight loss programs. The research states that services include low-calorie meal plans, FDA-approved appetite suppressants, GLP-1 medications such as Semaglutide and Tirzepatide, B-12 shots, and Bio-Identical Hormone Replacement Therapy.

Ameri-Cal Weight Clinic emphasizes a personalized approach that combines nutrition, exercise, medication, and support.

The clinic operates on a drop-in basis, which means no appointments are necessary for initial or follow-up visits.

The research also states that Ameri-Cal Weight Clinic does not accept insurance programs directly, but patients may be able to seek reimbursement by submitting an itemized receipt to their insurer.

Background and History

Ameri-Cal Weight Clinic was founded in 2000 by Dr. Ronald T. Weiland.

GLP-1 Weight Loss
  • Lose pounds of fat every week
  • Money Back Guarantee
  • No membership or hidden fees! Everything you need is included
  • Start for just $179, no insurance required + free shipping

The research states that Dr. Weiland expanded the clinic from one site to seven weight loss centers in the Bay Area. After Dr. Weiland’s passing in 2014, his son, Ron Weiland, became the Clinic Director, and Dr. William Brown became the Medical Director.

The clinic’s philosophy, as described in the research, centers on behavior adjustment regarding food, regular exercise, and prescribed appetite suppressants rather than fad diets.

Services and Programs

Ameri-Cal Weight Clinic offers a comprehensive weight loss program.

The research states that the program includes:

  • Low-calorie meal plans
  • FDA-approved appetite suppressants such as Phentermine
  • GLP-1 medications including Semaglutide and Tirzepatide
  • Vitamin B-12 and Lipotropic injections
  • Bio-Identical Hormone Replacement Therapy consultations and treatments
  • Cosmetic injectables such as Botox Cosmetic, Dysport, Juvederm, and Restylane

The clinic states that GLP-1 medications are prescribed after a thorough medical evaluation. These medications are described as helping regulate blood sugar and appetite, reducing hunger, and improving satiety for sustainable weight loss.

The clinic also states that it does not use HCG-based protocols. The research notes that the clinic cites studies showing that HCG is no more effective than a placebo and that ultra-low calorie diets with HCG may pose health risks.

Verification Notes

The research states that while Dr. William Brown is named as Medical Director, detailed credentials are not readily available on the clinic’s website.

Specific pricing for Semaglutide is not clearly listed on the clinic’s website. The clinic states that its prices are competitive and that it does not use hidden add-on fees for dosage increases, but actual GLP-1 pricing is not publicly detailed.

The research also notes that external reviews appear limited beyond Groupon and the BBB profile.

The clinic states that it uses FDA-approved appetite suppressants and GLP-1 prescriptions, but the specific pharmacy and medication sourcing details are not clearly outlined on the main program page.
