RED-S in Male Athletes: The Clinical Differential Most Sports RDs Are Missing
The literature, the screening tools, and the practice patterns around Relative Energy Deficiency in Sport are heavily female-coded. The male phenotype is real, prevalent in endurance and weight-class sport, and routinely misdiagnosed as "overtraining" or "low T from age." Here is the male-RED-S workup — the symptom cluster, the four-biomarker primary panel, the differential against primary hypogonadism and overtraining syndrome, and the energy-availability prescription that actually reverses it.
Iron-Status Workup in Female Athletes: The Ferritin → Transferrin Saturation → Reticulocyte Hemoglobin Protocol
Most labs flag iron deficiency only at the rickets-era hemoglobin threshold. By then the athlete has been performance-decremented for months. The fix is a three-marker primary panel — ferritin + transferrin saturation + reticulocyte hemoglobin — read against hs-CRP and the contraceptive method, with an every-other-day supplementation protocol that absorbs better than daily dosing.
Menstrual Cycle and Contraceptive Status Charting in the Female Athlete Intake: What the Sports RD Should Capture and Why
Most sports nutrition intakes capture menstrual status as a single "regular / irregular" checkbox — and never ask about the contraceptive method. That isn't a clinical record. Here is the chart structure I use for every female-athlete intake, with the eight fields per cycle history, the contraceptive cross-reference, and the SOAP block that makes downstream biomarker interpretation defensible.
Co-Treatment Documentation With Athletic Trainers: What the Sports RD Should Send, Receive, and Chart
Most sports dietitians work alongside athletic trainers on the same athletes — and most of those co-treatment relationships run on hallway conversations and group texts. Here is the documentation protocol that turns the AT-RD relationship into a clinical record both sides can defend, with the specific fields to capture and the cadence that keeps it working.
Supplement Reconciliation in the Sports Nutrition Intake: A Clinical Documentation Protocol
Most sports nutrition intakes capture supplement use as a single free-text line. That isn't reconciliation — it's stenography. Here is the clinical protocol I use to chart every product an athlete is taking, with dose, form, third-party testing status, interaction risk, and a defensible plan recommendation.
Calsanova Coach vs Registered Dietitian: Which One Is Right For You?
Calsanova's marketplace has two kinds of professionals: Registered Dietitians for clinical care and Certified Calsanova Coaches for performance accountability. Here's how to figure out which one fits what you actually need.
Becoming a Calsanova Coach: The Path, The Scope, The Earnings
Calsanova's Certified Coach tier is a non-RD performance-coaching pathway with a defined scope of practice, a 6-module curriculum, and a marketplace built for performance — not clinical care. Here's what the path looks like and what you'd earn.
Why We Built a Non-RD Coach Tier
Calsanova's marketplace started as an RD-only platform. We added a Certified Coach tier this year. Here's why — and what it means for the way the platform works.
Member Compliance Auditing in Sports Nutrition: Reading Food Logs Against Weight, Performance, and Body Composition Trends
Food logs lie. Body data does not. Performance data does not. A defensible sports nutrition prescription triangulates all three every two to four weeks — the compliance audit framework that turns the visit from a data-reconciliation exercise into a clinical-reasoning conversation.
Pre-Consult Intake Design for Sports Dietitians: The Data That Should Be Captured Before Session One
The first 45 minutes of a new-patient consult are usually wasted asking questions an intake form should have already answered. Here is the field-by-field framework for a sports nutrition intake that arrives at the first session pre-loaded — so the visit is for clinical reasoning, not data entry.
Insurance Reimbursement for Sports Nutrition: CPT Codes, Documentation, and the Medical Necessity Argument
Most sports dietitians leave money on the table by treating their practice as cash-only. Here is the framework for billing 97802, 97803, and G-codes in a sports nutrition workflow — including the documentation patterns that survive a payer audit and the cases where insurance reimbursement is the wrong play.
Hydration Status Assessment in Clinical Workflow: Reading the Markers That Actually Mean Something
Hydration is the fourth noisy clinical input in any sports nutrition workup — after RMR, body comp, and exercise energy expenditure. Here is the multi-marker framework a sports RD can use to read urine, body mass, and thirst data without getting fooled by any single number.
Interpreting RMR Tests in Sports Dietetics: When to Trust the Number, When to Ignore It
Indirect calorimetry RMR tests look definitive on the page. They are not. Here is the framework a sports RD can use to read RMR results in a clinical chart — including the pre-test conditions that invalidate a result, the prediction-equation reconciliation pattern, and the documentation note that holds up under audit.
Body Composition Reports as Bayesian Priors: Handling DXA, BIA, and Skinfold Noise in Clinical Workflow
DXA, BIA, and skinfold reports are likelihoods, not facts. Here is the Bayesian framework a sports RD can run in a clinical chart — including a worked example, a documentation pattern, and the three habits that separate clinicians who treat numbers as evidence from those who treat them as truth.
Estimating Exercise Energy Expenditure: When the Wearable Number Lies
Wearable kcal estimates are the most error-prone input in any sports nutrition calculation. Here is a three-method triangulation a sports RD can run without doubly-labeled water — and the documentation pattern that holds up under audit.
Screening Athletes for Low Energy Availability: A Clinical Protocol
Energy availability is the most under-screened clinical variable in sports nutrition. Here is a three-layer protocol a sports RD can run on a 100-athlete roster without burning out.
SOAP Notes for Sports Dietitians: What to Document, What to Skip
Clinical documentation is the single most under-taught skill in sports dietetics. Here is a working framework for writing SOAP notes that hold up in an audit and actually reflect your clinical work.
How AI Is Transforming Sports Nutrition
From automated meal planning to real-time food recognition, artificial intelligence is reshaping how dietitians fuel elite members. Here is what the shift looks like in practice.
A Dietitian's Guide to Macro Tracking for Athletes
Macro tracking is the backbone of performance nutrition. This guide covers how dietitians set targets, monitor compliance, and adjust macros across training phases.
Why HIPAA Compliance Matters for Nutrition Professionals
If you handle protected health information as a dietitian, HIPAA applies to you. This article breaks down what compliance looks like and why your software stack matters.
Building a Sports Nutrition Private Practice
More RDs are going into private practice to work with members directly. Here is what it takes to build a sustainable sports nutrition business.
The Business Case for AI in Your Dietetics Practice
AI is not just a clinical tool — it is a business multiplier. Here is how AI-powered workflows translate into more clients, less admin time, and higher revenue per RD.
