Major Jacob Frey has promoted his brother’s cancer-curing water-fasting retreat on Instagram …
Let’s investigate!
Who Are Asa and Joanna Frey, and What Is “Back to the Garden PR”?
Back to the Garden PR is an integrative health clinic and water‑fasting center based in Puerto Rico, founded and run by chiropractors Dr. Asa Frey and Dr. Joanna Frey. In their own materials and professional listings, the Freys present themselves as specialists in “integral health,” medically supervised fasting, and lifestyle‑based “disease reversal.”
Public profiles and the clinic’s website describe Asa Frey as a Doctor of Chiropractic educated at Boston University and Life University, with more than 15 years of clinical experience supervising thousands of water fasts. He is a member of the International Association of Hygienic Physicians, a fringe but organized network that promotes “natural hygiene” and water‑only fasting as a path to reversing chronic disease. The National Health Association, which runs a “Where to Water Fast” directory, lists “Back to the Garden PR – Asa and Joanna Frey, D.C.” as a fasting site in Puerto Rico, placing the clinic inside a small, self‑referential ecosystem of fasting providers.
Dr. Joanna Frey’s biography emphasizes a personal “awakening” around health and nature, followed by formal training in anatomy and physiology and an internship at TrueNorth Health Center in California, one of the best‑known water‑fasting clinics in the United States. She describes herself as integrating science, supervised fasting, and “education for a life aligned with nature,” and presents the Puerto Rico operation as both an outpatient clinic and a residential center for medically supervised water fasting and “integral health education.”
The Freys’ commercial footprint extends beyond the clinic’s exam rooms. They sell high‑ticket residential retreats such as week‑long stays at properties marketed as “La Casita” and “El Estudio,” with itemized packages that combine lodging, “clinical supervision,” and basic lab work for several thousand dollars per week. They also market multi‑month “Health Programs” priced around $2,800–$2,830, advertised as suitable for “children and adults in any state of health.” These programs bundle six clinical follow‑up visits (virtual or in person), individualized dietary plans, “supervised mimicking fasts,” ongoing education from the Freys, access to a WhatsApp “clinical support group,” and unlimited email contact with the doctors.
In parallel, the Freys run a subscription digital platform under the Back to the Garden brand. An app distributed through the major app stores offers more than 400–500 plant‑based recipes, cooking videos, educational talks, and “challenges” framed around the seven “pillars” of their integral‑health philosophy. The app and its membership tiers are administered by a corporate entity called Back To The Garden Chiropractic PC, using mailing addresses in San Juan’s Venus Gardens neighborhood. Clinic directories and satellite imagery, however, place “Clínica Back to the Garden PR” and the Freys’ chiropractic offices at a different medical complex and address, underscoring the distance between the brand’s polished online presentation and the patchwork of its on‑the‑ground operations.
Across these platforms, the Freys consistently describe themselves as having more than 15 years of experience “preventing and reversing chronic diseases,” including heart disease, diabetes, obesity, autoimmune conditions, skin problems, anxiety, and depression. Their marketing language leans heavily on “reversal,” “detoxification,” and “cellular regeneration,” and presents supervised fasting and strict plant‑based diets as powerful tools for transforming serious illness. What they do not provide is the kind of rigorous clinical data, transparent outcomes reporting, or independent oversight that would be expected if these claims were being made inside mainstream medicine.
The result is a profitable, tightly branded private health enterprise: a pair of chiropractors and their family‑run clinic, offering residential fasting retreats, intensive coaching programs, and a subscription content platform, all wrapped in the language of evidence‑based “integral health” and disease reversal—but operating largely outside conventional medical systems and without the guardrails those systems usually impose.
Back to the Garden PR claims they can reverse almost any disease as long as you can pay cash. The fact that Asa and Joanna Frey are listing “tipos de Cancer: in a list of disease they can reverse or cure, has no basis in science or logic.

The International Association of Hygienic Physicians —Snake Oil salesmen, or alternative healing?
The IAHP is a professional organization for doctors—primarily chiropractors and medical doctors—who practice "Natural Hygiene," a health philosophy centered on water-only fasting, nutrition, and lifestyle modifications.
Among other bogus claims made in this promo video, is the inclusion of a slide and excerpt where Joanna Frey states that water-fasting can cure certain types of cancer.
“Before fasting each visitor receives a detailed history, a comprehensive physical, psychological, and neurological examination”.
“We think this is by far the best strategy to build health, as well as reverse or prevent disease and the preponderance of the science strongly supports this idea as well”.
“Truly a paradise for fasting and evidence based heal re-integration”.
“Medically supervise water-only fasting has been proven to be safe and effective in the management of many conditions: High blood pressure and heart disease, diabetes, types of cancer, autoimmune diseases such as Lupus, Colitis, Arthritis, Asthma, Psoriasis, Hashimoto’s Thryoiditis, skin conditions, and many more!”
