How Do I Enter My Baseline Metrics in the Calibrate App?

Why Baseline Metrics Matter Before You Start a GLP-1 Program

Your baseline data is the clinical starting line. Without accurate numbers on day one, your Calibrate physician cannot safely select a starting dose of semaglutide or tirzepatide, cannot identify contraindications, and has no reference point for measuring progress.

The FDA-approved label for semaglutide 2.4 mg (Wegovy) specifies adult patients with a BMI ≥30 kg/m², or BMI ≥27 kg/m² with at least one weight-related comorbidity such as hypertension, type 2 diabetes, or dyslipidemia. [1] Confirming that threshold is the first thing your metrics accomplish.

What the Research Says About Baseline Data Quality

Poor baseline documentation is not a paperwork inconvenience. In the STEP-1 trial (N=1,961), participants who completed full baseline assessments, including fasting glucose, HbA1c, lipid panel, and anthropometrics, received protocol-consistent semaglutide titration that yielded 14.9% mean body weight loss at 68 weeks versus 2.4% in the placebo group (P<0.001). [2] Incomplete baselines in real-world programs are associated with slower titration and suboptimal outcomes.

The American Association of Clinical Endocrinology (AACE) 2023 Obesity Clinical Practice Guidelines state: "Comprehensive baseline metabolic assessment, including glycemic status, lipid profile, liver function, and blood pressure, should precede initiation of any pharmacological obesity treatment." [3] That guideline maps almost exactly to what Calibrate collects.

Clinical Significance of Each Metric

Each number your care team requests ties directly to a prescribing or safety decision.

Fasting glucose and HbA1c determine whether you have prediabetes or type 2 diabetes, which affects GLP-1 dose selection and monitoring frequency. [4] Liver enzymes (ALT, AST) screen for non-alcoholic fatty liver disease, which is present in roughly 25% of adults with obesity and may influence titration pace. [5] Blood pressure readings above 140/90 mmHg at baseline prompt additional cardiovascular risk stratification per the American Heart Association's 2017 Hypertension Guidelines. [6]

Step-by-Step: Entering Your Baseline Metrics in the Calibrate App

The process takes roughly 10 to 15 minutes on a smartphone. Follow these steps in order to avoid missing any required fields before your first provider video visit.

Step 1. Download and Log In

Download the Calibrate app from the Apple App Store or Google Play Store. Use the email address you provided during enrollment. Two-factor authentication is required on first login.

Once inside, you will see a dashboard with a prompt reading something like "Complete your health profile" or "Add your baseline data." Tap that card. If the prompt does not appear, manage to the bottom navigation bar and select "My Health."

Step 2. Enter Anthropometric Measurements

The app will ask for:

• Height (feet/inches or centimeters)
• Current body weight (pounds or kilograms, measured first thing in the morning, after using the bathroom, without shoes)
• Waist circumference (measured at the level of the umbilicus, not the narrowest point)

Waist circumference is not cosmetic data. Abdominal adiposity independently predicts cardiometabolic risk. The National Heart, Lung, and Blood Institute defines high-risk thresholds as greater than 40 inches (102 cm) in men and greater than 35 inches (88 cm) in women. [7] Your Calibrate physician uses that value alongside BMI to assess visceral fat burden before prescribing.

Weigh yourself on the same scale each time, ideally a digital scale accurate to 0.1 lb. Inconsistent equipment introduces noise into your progress tracking.

Step 3. Enter Blood Pressure and Heart Rate

You will need a home blood pressure cuff or a recent reading from a clinical setting (within 30 days). Sit quietly for five minutes before measuring. Take two readings, one minute apart, and enter the average.

Heart rate above 100 bpm at rest may flag sinus tachycardia, which is relevant because GLP-1 receptor agonists are associated with a mean heart rate increase of approximately 1 to 4 bpm in clinical trials. [8] Your provider may order additional cardiac evaluation if baseline resting heart rate is elevated.

Step 4. Upload or Manually Enter Lab Values

This is the step most users skip or delay, and it is the one most likely to slow down your first prescription.

If your primary care physician has ordered labs within the past 90 days, you can upload a PDF of the results directly in the "Labs" section of the app. Alternatively, Calibrate may direct you to a partner lab (Quest Diagnostics or LabCorp, depending on your location) for a baseline panel.

The standard Calibrate baseline lab panel typically includes:

• Fasting glucose
• HbA1c
• Complete metabolic panel (CMP), which covers liver enzymes and kidney function
• Fasting lipid panel (total cholesterol, LDL, HDL, triglycerides)
• TSH (thyroid-stimulating hormone) to screen for hypothyroidism, a common contributor to weight gain

The American Diabetes Association's 2024 Standards of Care recommend HbA1c testing for all adults with obesity or overweight, given that type 2 diabetes is present in approximately 11.6% of U.S. Adults and remains undiagnosed in an estimated 8.5 million of them. [4] Entering a normal HbA1c confirms GLP-1 safety; a high value changes the clinical approach entirely.

Step 5. Complete the Health History Questionnaire

After biometrics and labs, the app presents a structured questionnaire covering:

• Current medications (critical for drug interaction screening)
• Personal history of pancreatitis, thyroid cancer, or multiple endocrine neoplasia type 2 (MEN2), which are absolute contraindications to GLP-1 agonists per FDA labeling [1]
• Family history of medullary thyroid carcinoma
• Gastrointestinal history (gastroparesis, inflammatory bowel disease)
• Mental health history, because GLP-1 agents carry an FDA label update noting reports of suicidal ideation in some patients [9]

Answer every question. Skipping a contraindication screen does not make the contraindication disappear; it means your physician prescribes without complete information.

Step 6. Sync a Wearable or Health App (Optional but Recommended)

Calibrate supports Apple Health and Google Fit integration. Syncing allows automatic daily weight logging, step count, resting heart rate, and sleep duration to flow into your dashboard without manual entry.

Research from the National Institutes of Health supports the clinical value of continuous self-monitoring. A 2020 study published in Obesity (PMID 32372583) found that participants who tracked weight daily lost significantly more weight over 12 months than those who weighed weekly or not at all. [10] Daily syncing from a smart scale removes the friction of manual logging and captures trends your physician reviews before each check-in.

Step 7. Confirm Submission and Review With Your Provider

After entering all required fields, tap "Submit" or "Save Profile." The app will display a confirmation screen. Your assigned Calibrate physician receives a notification that your profile is complete and will review your data before scheduling or confirming your first video visit.

If any lab values fall outside normal ranges, your physician may message you through the in-app secure messaging system before the visit to request additional testing.

Common Errors to Avoid When Entering Baseline Metrics

Entering Weight at the Wrong Time of Day

Body weight fluctuates by 1 to 3 kg across a single day depending on food intake, hydration, and bowel habits. [11] Enter your weight first thing in the morning, after voiding, before eating or drinking. This matches the protocol used in clinical trials like STEP-1 and SURMOUNT-1, making your data comparable to the evidence base your physician references.

Using a Waist Measurement From Clothing Labels

Clothing waist sizes are vanity measurements. Pant waist sizes in U.S. Retail commonly run 1 to 2 inches smaller than actual anatomical circumference. Measure with a flexible tape measure placed directly on skin at the level of the navel, parallel to the floor, at the end of a normal exhale.

Uploading Labs Older Than 90 Days

Lab values older than 90 days may not reflect your current metabolic state, particularly if you have changed your diet, started new medications, or experienced significant weight change. The AACE 2023 guidelines recommend repeat baseline metabolic assessment if more than 3 months have elapsed since prior testing before initiating pharmacotherapy. [3]

Omitting Medications

Many users forget to list over-the-counter supplements, particularly those containing stimulants (synephrine, high-dose caffeine) or those that affect thyroid function (biotin at doses above 5 mg/day can falsely lower TSH readings). [12] List every substance, prescribed or not.

What Happens to Your Baseline Data After Submission

Provider Review and Dose Selection

Your Calibrate physician reviews your complete profile, typically within 24 to 48 hours of submission. They use your BMI, HbA1c, blood pressure, and lab values to determine:

1. Whether you meet FDA eligibility criteria for semaglutide (Wegovy) or, where available, tirzepatide (Zepbound)
2. Your starting dose (semaglutide typically begins at 0.25 mg weekly for 4 weeks before titration to 0.5 mg)
3. Any pre-treatment interventions needed (e.g., blood pressure control before GLP-1 initiation)

The SURMOUNT-1 trial (N=2,539) demonstrated that tirzepatide 15 mg produced 20.9% mean body weight loss at 72 weeks in adults with obesity. [13] Reaching that outcome safely required a structured 20-week titration period starting at 2.5 mg weekly. Your baseline metrics determine where on that titration ladder your physician starts you.

Tracking Progress Against Baseline

Every metric you enter on day one becomes the denominator for your progress calculations. At 4-week, 12-week, 24-week, and 52-week check-ins, your Calibrate physician compares new readings against those baselines to assess response.

A weight loss of less than 5% of initial body weight after 12 to 16 weeks on a stable dose is generally considered an inadequate response per AACE guidelines, and may prompt a dose increase or medication switch. [3] That judgment is only possible if the starting point is documented accurately.

Data Portability and Medical Records

Your Calibrate health profile, including all baseline metrics, constitutes part of your medical record. Under HIPAA and the 21st Century Cures Act, you have the right to request a full export of that data at any time. [14] The app provides a "Download My Records" function in the account settings menu.

How Baseline Metrics Connect to Your Four-Pillar Program

Calibrate structures its program around four domains: medication, food, sleep, and exercise. Each baseline metric feeds at least one of those pillars.

The table below maps each baseline metric to its clinical purpose and the program pillar it informs.

| Metric | Clinical Purpose | Program Pillar | |---|---|---| | Body weight and BMI | GLP-1 eligibility, dose selection, progress tracking | Medication, Food | | Waist circumference | Visceral adiposity and cardiometabolic risk | Food, Exercise | | Fasting glucose and HbA1c | Diabetes screening, GLP-1 safety | Medication | | Lipid panel | Cardiovascular risk stratification | Food, Medication | | Blood pressure | Cardiovascular risk, titration pace | Medication, Exercise | | Resting heart rate | Baseline cardiac function, GLP-1 monitoring | Medication, Exercise | | TSH | Rule out hypothyroidism as weight-gain driver | Medication | | Liver enzymes (ALT/AST) | NAFLD screening, titration safety | Food | | Sleep duration (from wearable) | Sleep disorder screening, metabolic impact | Sleep | | Step count (from wearable) | Physical activity baseline | Exercise |

Poor sleep is not just a wellness concern. Adults sleeping fewer than 6 hours per night show measurable dysregulation of ghrelin and leptin, the appetite-regulating hormones that GLP-1 agonists also target. A 2022 review in the Journal of Clinical Endocrinology and Metabolism found that sleep restriction increased ad libitum caloric intake by approximately 300 kcal/day in controlled conditions. [15] Your sleep baseline tells the coaching team where behavioral support is needed most.

Troubleshooting: If the App Will Not Accept Your Data

App Shows an Error When You Try to Save Weight

Check that you have selected the correct unit (lbs vs. Kg). The app defaults to lbs for U.S. Users. Entering "75" while the unit toggle is set to lbs produces an implausibly low weight that triggers a validation error. Switch the toggle to kg if you measured in metric.

Lab Upload Is Rejected

Calibrate accepts PDFs and JPEGs of lab reports. Screenshots taken on a phone are often rejected due to insufficient resolution. Download the official PDF from your patient portal (MyChart, LabCorp Patient, Quest MyQuest) and upload that file directly.

You Do Not Have Recent Labs

Message your Calibrate care team through the in-app secure messaging system before your first visit. They can issue a lab order through a partner laboratory, typically with results available within 48 to 72 hours. Do not attempt to estimate lab values or leave fields blank.

Wearable Sync Is Not Working

Go to your phone's Health app (iOS) or Google Fit (Android) and confirm that Calibrate has permission to read the relevant data types. On iOS, manage to Settings, then Privacy, then Health, then Calibrate, and toggle on all categories. On Android, open Google Fit, tap profile, then "Manage connected apps," and confirm Calibrate is listed and active.

Baseline Metrics at Follow-Up Visits: What Repeats and When

Entering baseline data is not a one-time task. The Calibrate protocol calls for updated metric entry at scheduled intervals. Repeat measurement timing is based on clinical evidence for minimum detectable change.

Body weight should be logged daily via wearable sync or manually, with a formal "weigh-in" at each 4-week coaching check-in. A 2021 meta-analysis in JAMA Network Open found that digital self-monitoring of weight combined with coaching feedback produced significantly greater weight loss than standard care at 12 months. [16]

HbA1c is typically repeated at 3 months and 6 months for patients with prediabetes or diabetes, consistent with the American Diabetes Association's 2024 Standards of Care recommendation for quarterly HbA1c assessment in patients on pharmacological treatment. [4]

Blood pressure should be re-entered at every visit if you have a baseline reading above 130/80 mmHg. Semaglutide reduces systolic blood pressure by a mean of 3 to 6 mmHg in patients with obesity, a clinically meaningful effect documented in the STEP-1 trial. [2]
