  • According to the information provided, Ameri-Cal Weight Clinic specializes in medically supervised weight loss treatment through an outpatient program. This includes a low calorie diet, FDA approved appetite suppressants, GLP-1 drugs such as Semaglutide and Tirzepatide, B-12 injections, and Bio-Identical Hormone Replacement Treatment.

Background and History

  • Ameri-Cal Weight Clinic was started in 2000 by Dr. Ronald T. Weiland.
  • The research shows that Dr. Weiland grew the clinic from a site to seven weight loss centers in the Bay Area. After Dr. Weiland passed away in 2014 his son Ron Weiland took over as Clinic Director.
  • The clinic focuses on changing behavior around food, exercising regularly and using suppressants.

Services and Programs

Ameri-Cal Weight Clinic has a weight loss program that covers everything you need.

The program is made up of things, including:

  • 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

Ameri-Cal Weight Clinic says that they only prescribe GLP-1 medications after a thorough medical evaluation. These GLP-1 medications help with things like regulating blood sugar and appetite, reducing hunger and making you feel full which is good for weight loss.
