Excess body fat — particularly visceral fat — is brain-toxic. It produces inflammatory cytokines that cross the blood-brain barrier and accelerate cognitive aging. BMI is a crude metric, but it is a starting point. Use this calculator, then take the free Personalized Assessment to see your full metabolic risk profile.
Enter your height and weight to calculate your BMI and see what it means for your cognitive longevity and metabolic health.
BMI is a starting point. Here is what it actually tells you — and what it does not — about your cognitive longevity risk.
Visceral fat — the abdominal fat that surrounds your organs — is not inert storage. It is metabolically active tissue that produces chronic systemic inflammation.
BMI is a screening proxy — useful as a first filter, limited as a complete picture. It correlates with visceral fat burden at the population level, but individual variation is significant.
The free Personalized Assessment goes beyond BMI to assess your full metabolic and cognitive risk profile — in 5 minutes.
Each BMI range carries different implications for neuroinflammatory risk and metabolic health.
BMI is within a healthy range, but this does not automatically mean low visceral fat. Men with normal BMI can still carry significant central adiposity — particularly if lean mass is low. The Personalized Assessment provides a more complete picture. Focus on maintaining lean mass through resistance training and supporting metabolic health proactively.
Visceral fat accumulation is likely beginning to drive low-grade systemic inflammation. For men, this is the range where the neuroinflammatory burden starts to compound year over year. It is also the range where proactive intervention — protocol-level lifestyle change and, in some cases, clinical support — produces the best long-term cognitive return. Take the Personalized Assessment to assess your full risk profile.
At this BMI range, visceral fat burden is clinically significant. Systemic inflammation is likely elevated. Insulin resistance, hormonal suppression (particularly testosterone via aromatization), and sleep architecture disruption are common. The neuroinflammatory load is real and measurable. This is also the primary threshold for GLP-1 medication eligibility. A comprehensive 4M consult is the appropriate next step.
Visceral fat at this level produces persistent, high-load neuroinflammation. Metabolic syndrome, insulin resistance, cardiovascular risk, sleep apnea, and hormonal disruption are common. The good news: this is also where GLP-1 medications produce the most dramatic metabolic and inflammatory reduction — particularly when combined with the 4M protocol. Do not wait. Book a comprehensive 4M consult.
GLP-1 medications — semaglutide and tirzepatide — are powerful clinical tools for reducing visceral fat and restoring metabolic function. They are not a standalone fix; they are one lever within the 4M framework. If your BMI is 30 or higher (or 27 or higher with a weight-related comorbidity), GLP-1 therapy may be clinically appropriate for your protocol.
Final eligibility is confirmed through a comprehensive 4M consult with a contracted licensed telemedicine provider — not a BMI calculator. The consult reviews your full health history, metabolic markers, and whether GLP-1 therapy is appropriate and which agent fits your profile.

Answers to common questions about BMI and GLP-1 medication eligibility.
A BMI of 30 or higher generally qualifies adults for GLP-1 weight loss medication. A BMI of 27 to 29.9 may qualify with at least one weight-related health condition such as type 2 diabetes, high blood pressure, high cholesterol, or obstructive sleep apnea. Final eligibility is determined by a licensed physician during consultation.
BMI is calculated by dividing your weight in kilograms by the square of your height in meters (kg/m²). In imperial units, multiply your weight in pounds by 703, then divide by the square of your height in inches.
No. BMI is the primary screening criterion, but your physician will also review your medical history, current medications, existing health conditions, contraindications, and overall goals before prescribing GLP-1 medication. BMI is a first-pass indicator, not a final determination.
The WHO categories for adults are: underweight (below 18.5), normal (18.5–24.9), overweight (25.0–29.9), and obese (30.0+). Obesity is further divided into class I (30.0–34.9), class II (35.0–39.9), and class III (40+).
Yes. BMI does not distinguish between muscle and fat mass, so highly muscular individuals may have a high BMI without excess body fat. BMI also does not account for fat distribution or body composition. Your physician may consider additional measures like waist circumference alongside BMI.
GLP-1 weight loss medications are generally not prescribed for adults with a BMI below 27. If your BMI is in the normal or mildly overweight range, nutrition counseling, exercise, and behavioral support may be more appropriate. A physician can help you choose the safest and most effective path for your goals.
