Calculate My BMI →What is Zepbound?
Zepbound is the brand name for tirzepatide, a once-weekly injectable medication made by Eli Lilly. It was FDA-approved in November 2023 specifically for chronic weight management in adults with obesity or overweight with health complications.
Tirzepatide works by activating two hormone receptors — GIP and GLP-1 — that regulate appetite, blood sugar, and fat storage. In clinical trials, patients lost an average of 15 to 22% of their body weight over 72 weeks, making it one of the most effective weight loss medications ever approved.
What BMI Do You Need for Zepbound?
The FDA approval specifies two qualifying pathways:
| Path | BMI Requirement | Additional Requirement | Qualifies? |
|---|---|---|---|
| Path 1 | BMI 30 or above | None — BMI alone qualifies | ✅ Yes |
| Path 2 | BMI 27 to 29.9 | At least one weight-related health condition | ✅ Yes, with condition |
| Not eligible | BMI below 27 | Any | ❌ No |
In simple terms: BMI 30+ qualifies automatically. If your BMI is 27, 28, or 29.9, you can still qualify — but only if a doctor has diagnosed you with at least one of the qualifying health conditions listed below.
What Health Conditions Qualify You at BMI 27?
If your BMI is between 27 and 29.9, you need at least one of these weight-related conditions documented by your doctor:
| Qualifying Condition | Why It Qualifies |
|---|---|
| Type 2 Diabetes | Excess weight drives insulin resistance — weight loss significantly improves blood sugar control |
| High Blood Pressure (Hypertension) | Losing 10% body weight can reduce systolic BP by 5–10 mmHg |
| High Cholesterol (Dyslipidemia) | Weight loss improves LDL, HDL, and triglyceride levels |
| Obstructive Sleep Apnea | Weight reduction often eliminates or significantly reduces sleep apnea episodes |
| Cardiovascular Disease | Excess weight is a major modifiable risk factor for heart attack and stroke |
Important: The condition must be formally diagnosed, not just suspected. Your doctor will need documentation in your medical record.
What BMI Means in Actual Pounds — Am I at 27 or 30?
Here is what BMI 27 and BMI 30 look like in real weight at common heights:
| Height | BMI 27 (Path 2 minimum) | BMI 30 (Path 1 minimum) | BMI 35 | BMI 40 |
|---|---|---|---|---|
| 5'2" | 147 lbs | 164 lbs | 191 lbs | 218 lbs |
| 5'4" | 157 lbs | 174 lbs | 204 lbs | 233 lbs |
| 5'5" | 162 lbs | 180 lbs | 210 lbs | 240 lbs |
| 5'6" | 167 lbs | 186 lbs | 216 lbs | 247 lbs |
| 5'7" | 172 lbs | 191 lbs | 223 lbs | 254 lbs |
| 5'8" | 177 lbs | 197 lbs | 230 lbs | 263 lbs |
| 5'10" | 188 lbs | 209 lbs | 243 lbs | 278 lbs |

How Much Weight Can You Lose on Zepbound?
Clinical trial results from the SURMOUNT program showed impressive outcomes:
| Zepbound Dose | Average Weight Loss | % of Body Weight | Trial Duration |
|---|---|---|---|
| 5 mg/week | ~35 lbs | ~15% | 72 weeks |
| 10 mg/week | ~46 lbs | ~19.5% | 72 weeks |
| 15 mg/week | ~52 lbs | ~22% | 72 weeks |
| Placebo | ~5 lbs | ~2.5% | 72 weeks |
For a 200 lb person, 22% weight loss equals 44 lbs — enough to drop from BMI 30 to BMI 23.4 at 5'8", moving from obese to normal weight. Results vary significantly by individual.
How to Get Zepbound — Step by Step
The Zepbound Approval Process
- 1Calculate your BMI. Use our BMI calculator to confirm you meet the 27+ or 30+ threshold before your appointment.
- 2Schedule a doctor appointment. Primary care physician, endocrinologist, or obesity medicine specialist. Telehealth services like Ro Body, Found, and Calibrate also prescribe Zepbound.
- 3Discuss your health history. Bring documentation of any qualifying conditions (diabetes, hypertension, etc.). Your doctor will review your full health picture.
- 4Prior authorization. If your insurance covers Zepbound, prior authorization is almost always required. Your doctor's office handles this — expect 1 to 4 weeks.
- 5Start at 2.5 mg/week. Dose escalates every 4 weeks: 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg. Most people reach maintenance dose at 10 or 15 mg.
Who Cannot Take Zepbound?
Even if you meet the BMI criteria, Zepbound may not be right for everyone. It is contraindicated for people with:
- Personal or family history of medullary thyroid carcinoma (MTC)
- Multiple Endocrine Neoplasia syndrome type 2 (MEN 2)
- Pregnancy or planning to become pregnant (must stop at least 2 months before conception)
- Serious hypersensitivity reaction to tirzepatide
- Type 1 diabetes (not approved for this use)
Side effects include nausea, vomiting, diarrhea, and constipation — most common during dose escalation and typically improving over time.
