Background and History

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

The research states that Dr. Weiland began with one clinic and expanded the business into seven weight loss centers in the Bay Area.

His philosophy focused on:

  • A calorie-deficit diet
  • Regular exercise
  • Prescribed appetite suppressants

The clinic’s approach is described as rejecting “fad diets.”

After Dr. Weiland’s passing in 2014, his son Ron Weiland became Clinic Director, and Dr. William Brown took over as Medical Director.

The research states that the clinic continues the same legacy of care and highlights real people who have achieved results through its programs.

  • I was fast to be seen. he explains and answers questions clearly. I will go again.
  • I went there once with my friend and we got pills to suppress hunger, but what we didnt know is the pills suppresses sleeping as well. We couln’t sleep with the pills that was given to us. We received a shot but that did not work either. I haven’t heard back from this business as to what they can do for us and group-on will not give me a full refund for this horrible business. I bought 2 group-on 1 for me and the other for my friend. I paid $158 for 2 and truly a waste of my time and money.

Pricing and Value Signals

The clinic states that its prices are fair, honest, and competitive.

The research states that Ameri-Cal keeps costs down by focusing on weight-loss basics and by not performing EKGs or blood workups, instead expecting patients to get those through their annual physical exams.

Initial Visit

The initial visit includes:

  • Physician consultation
  • Body composition data
  • Goal setting
  • Low-calorie meal plans
  • Four weeks of appetite suppressants or GLP-1 prescriptions

Optional injections available include:

  • Vitamin B-12
  • Lipotropic injections

  • Cash
  • Check

Pricing Notes

The website states: “Call for pricing details.”

A past Groupon offer, now expired, listed:

  • A four-week initial visit for $79
  • Follow-up visits at $150 per visit

The research notes that exact pricing for semaglutide and other GLP-1 medications is not clearly listed on the website beyond their inclusion in the initial program.

Verification Notes

The research highlights several gaps and caution points:

  • There is conflicting BBB information, with one listing showing an A+ rating and another saying the Antioch business is believed to be out of business
  • Specific pricing for semaglutide and other GLP-1 services is not fully detailed online
  • Detailed bios and credentials for medical staff beyond the founder, clinic director, and medical director are not readily available on the main website
  • Most public reviews found are older, largely from Groupon, so newer public feedback would provide a more current picture
