Key takeaways
  • FDA approval requires BMI ≥30, or BMI ≥27 with weight-related comorbidity
  • Candidacy is not just BMI—your clinician evaluates health history, medications, and goals
  • Realistic expectations matter: GLP-1 medications are tools, not magic solutions
  • PEAK evaluates every patient face-to-face before prescribing

FDA candidacy criteria for Wegovy and Zepbound

Both Wegovy (semaglutide) and Zepbound (tirzepatide) are FDA-approved for chronic weight management in adults who meet specific criteria:

BMI of 30 or higher (obesity)
If your BMI is 30 or above, you may qualify for GLP-1 medication as part of a structured weight management plan that includes reduced-calorie diet and increased physical activity.

BMI of 27 or higher with at least one weight-related comorbidity
If your BMI is between 27 and 29.9, you may qualify if you have at least one of the following conditions:

These are FDA criteria. Insurance plans may have additional requirements, such as documented lifestyle modification efforts or step-therapy protocols requiring you to try other medications first. At PEAK, we handle these requirements and manage prior authorization submissions for you.

BMI is a starting point, not the whole story

BMI is an imperfect tool. It doesn't account for muscle mass, body composition, or metabolic health. Your clinician will consider your full health picture—not just a number on a chart—when determining whether GLP-1 therapy is appropriate.

What the clinical evaluation includes

At PEAK, candidacy is determined through a face-to-face consultation with a clinician. This is not a questionnaire you fill out online. It's a medical evaluation.

Health history review

Your clinician will review your medical history, including:

Physical examination

Your initial visit includes a physical exam, baseline vital signs (blood pressure, heart rate), and body composition analysis using a Styku 3D body scan. This gives your clinician a detailed picture of your muscle mass, body fat percentage, and metabolic health—not just your weight.

Lab work

Baseline labs are ordered to assess thyroid function, kidney function, liver enzymes, lipid panel, hemoglobin A1C, and other metabolic markers. This ensures there are no underlying conditions that would make GLP-1 therapy unsafe or ineffective.

Goal-setting conversation

Your clinician will ask about your weight loss goals, your motivations, and what success looks like to you. This is where realistic expectations are established. If you're hoping to lose 50 pounds in 3 months, your clinician will help you understand what's clinically realistic—and what's not.

GLP-1 medications work best when patients understand they're one tool in a broader plan—not a shortcut or a replacement for lifestyle changes.

Setting realistic expectations

Clinical trials show average weight loss of approximately 15% with Wegovy (68 weeks) and up to 22.5% with Zepbound (72 weeks), when combined with lifestyle modifications. But "average" means some patients lose more, and some lose less. Individual results depend on adherence, metabolic response, nutrition, physical activity, sleep, stress, and genetics.

Here's what GLP-1 medications do well:

Here's what they don't do:

At PEAK, we're transparent about this from the first visit. If you're looking for a prescription-only solution, GLP-1 therapy probably isn't the right fit. If you're ready to pair medication with real behavior change, we can help you build a plan that works.

What "success" looks like

For some patients, success is losing 40 pounds. For others, it's getting off diabetes medication, improving sleep apnea, or finally feeling in control of food cravings. Your clinician will help you define success in a way that's meaningful and achievable for your situation.

Who is not a candidate for GLP-1 medications

Certain conditions make GLP-1 medications inappropriate or unsafe. Your clinician will not prescribe Wegovy or Zepbound if you have:

Additionally, if your BMI does not meet FDA criteria and you do not have documented weight-related comorbidities, your clinician will not prescribe GLP-1 medications for weight loss. This is not gatekeeping—it's practicing within FDA-approved indications and insurance coverage rules.
