About Dr. Caplan

A physician who takes the whole picture seriously

Dr. Benjamin Caplan, MD is a board-certified family physician
with more than two decades of clinical practice.

His work has moved across primary care, specialty medicine,
clinical research, digital health, and large-scale patient care
systems. The habit underneath it has remained remarkably
consistent: understand the patient before deciding what to do.

The Clinical Foundation

Family medicine is built around context

Weight, appetite, blood sugar, sleep, medications, mood, hormones,
cardiovascular risk, and daily life do not arrive in separate
boxes. They interact.

That is the lens Dr. Caplan brings to metabolic care. He trained
in family medicine at Tufts University School of Medicine and
Boston Medical Center, then spent more than two decades caring
for patients whose health rarely fit neatly into a single
diagnosis.

GLP-1 treatment is one clinical tool inside that larger picture.
The question is not simply whether a medication can be prescribed.
The question is whether it makes sense for this patient, at this
point in their health, with these goals and these competing
considerations.

The work that shaped this practice

Clinical judgment develops over time, across patients, research,
failures, difficult questions, and repeated follow-up.

Direct patient care

More than two decades of clinical medicine

Dr. Caplan’s foundation is conventional family medicine:
Williams College, Tufts University School of Medicine, and
family medicine training through Boston University and Boston
Medical Center.

CED Clinic has since served more than 30,000 patients, creating
years of experience with longitudinal care, complex medication
histories, treatment uncertainty, and the practical realities
of helping patients make decisions over time.

Research and evidence

Clinical curiosity with scientific discipline

Dr. Caplan has published in the New England Journal of Medicine
and serves as Principal Investigator on clinical research
studies.

He also maintains an extensive primary-literature research
library developed through years of evidence review. The purpose
is practical: to distinguish what is established, what is
promising, and what the available evidence cannot yet support.

Teaching and communication

Making complicated medicine understandable

Dr. Caplan delivered the first Cannabis Medicine lecture at
Harvard Business School and helped launch the school’s first
Cannabis Business Conference.

He is also the author of
The Doctor-Approved Cannabis Handbook, published by
Penguin Random House. Across teaching, writing, and clinical
practice, the goal is the same: give people enough context to
make better decisions without pretending complex medicine is
simple.

Clinical systems

Building care beyond the examination room

Dr. Caplan has helped build digital health, clinical education,
and data-informed care systems, including EO Care and other
healthcare technology initiatives.

He also serves in clinical leadership for The Commonwealth
Project, a program focused on senior care, access, outcomes,
and the challenge of making novel care models clinically
reproducible at scale.

A fair question

Why does a cannabis medicine background belong on a metabolic care page?

Because specialty cannabis medicine required years of working in
a clinical environment where enthusiasm often moved faster than
evidence, patients arrived with complicated medication histories,
and generic protocols routinely failed to capture the whole
picture.

That work sharpened a useful clinical habit: separate signal from
promotion, understand what the patient is actually trying to
accomplish, start thoughtfully, observe what happens, and adjust
based on the person rather than the protocol alone.

Metabolic medicine is a different field. The medications,
evidence base, and regulatory pathways are different. The clinical
discipline of careful evaluation and longitudinal follow-up,
however, transfers remarkably well.

Why Metabolic Care

Why add metabolic care to this practice?

After years of patient conversations, metabolic health keeps
recurring across many of the chronic problems people struggle
with: weight, appetite regulation, blood sugar, sleep, energy,
medications, and long-term function.

GLP-1 medications represent a meaningful advance in metabolic
medicine. Their value still depends on choosing the right patient,
understanding the indication, setting realistic expectations, and
staying engaged after the first prescription.

Much of the current GLP-1 marketplace is optimized for speed and
volume. This service is built for the patient who wants a physician
to slow down long enough to think.

What patients say about Dr. Caplan

“He was the first doctor I have seen in years who actually seemed
interested in understanding my situation rather than processing me
through a system.”

Patient, initial metabolic consultation

“I appreciated that he was honest about what the medication can and
cannot do. No overselling. No pressure. Just a real conversation
about what might actually work for me.”

Patient, ramp-up visit

“I had seen other telehealth services. This was different. There was
a clear sense that he had read my history, thought about my
situation, and had actual opinions about what I should do.”

Patient, maintenance care after transfer
