Weight Loss · Candidate Selection · May 2026

Are you a candidate for GLP-1 therapy?

The fastest way to know whether semaglutide or tirzepatide is right for you is the same way we figure it out at consultation: BMI, comorbidities, contraindications, labs, and goals. Here is the framework — including the patients we deliberately decline to prescribe for.

The Quick Answer

The two-minute self-assessment.

Before any of the nuance, the FDA-labeled criteria for the obesity indication of semaglutide (Wegovy) and tirzepatide (Zepbound) are clear. You are eligible if you meet either:

Tirzepatide is also FDA-approved for obstructive sleep apnea in adults with obesity (regardless of weight goals). Semaglutide is approved as adjunct therapy for type 2 diabetes and for cardiovascular event reduction in patients with established CV disease.

"FDA criteria are the floor. Whether a GLP-1 is the right tool for you depends on the labs, the comorbidities, the goals, and the alternatives we have not yet tried."
Yes vs. No

Who we say yes to — and who we say no to.

— Strong Candidates

Patients we readily prescribe for

  • BMI ≥ 30 with motivation for sustained therapy and lifestyle change
  • BMI 27–29 with at least one comorbidity (T2D, HTN, dyslipidemia, OSA, MASLD)
  • Type 2 diabetes with A1c > 7% on metformin alone
  • Established cardiovascular disease (semaglutide has SELECT-trial MACE benefit)
  • Obstructive sleep apnea with obesity (tirzepatide is FDA-approved for this)
  • Post-menopausal women with hormone-corrected weight that has plateaued
  • Patients who have lost weight previously and regained — including post-bariatric regain
— Decline / Defer

Patients we deliberately do not prescribe for

  • Personal or family history of medullary thyroid carcinoma (MTC)
  • Multiple endocrine neoplasia type 2 (MEN-2)
  • Active or recent pancreatitis
  • Severe gastroparesis (GLP-1s slow gastric emptying further)
  • Active eating disorder (anorexia, bulimia) — drug masks the disorder
  • Pregnancy, planning pregnancy in next 60 days, or breastfeeding
  • BMI < 25 with no metabolic disease — the risk/benefit does not favor drug therapy
  • Patients seeking short-term cosmetic weight loss with no plan for ongoing therapy or lifestyle anchors
  • Patients unable or unwilling to commit to baseline labs and follow-up monitoring
Screening Labs

What we order before the first prescription.

No GLP-1 prescription leaves the practice without a baseline panel. The labs serve three purposes: confirm eligibility, identify confounders, and establish a baseline against which response is measured.

TestWhy we order it
Comprehensive metabolic panel (CMP)Liver enzymes (ALT/AST), kidney function (creatinine, GFR), electrolytes, glucose
Hemoglobin A1cDiabetes status; baseline for tracking glycemic response
Fasting insulin + glucoseHOMA-IR calculation; identifies insulin resistance not yet meeting diabetes criteria
Lipid panelBaseline LDL, HDL, triglycerides; identifies dyslipidemia comorbidity
Thyroid panel (TSH, free T4, free T3, TPO)Rule out subclinical hypothyroidism that mimics weight resistance; document baseline for MTC risk discussion
Hormones — sex (testosterone, estradiol, SHBG, LH/FSH, progesterone in women)Hypogonadism caps weight-loss response; perimenopausal hormone shifts drive much of midlife weight gain
hs-CRPInflammatory burden; metabolic disease marker
Vitamin D, B12Common deficiencies; B12 absorption affected by metformin (often co-prescribed)
Pregnancy test (women of childbearing age)Required before initiation
DEXA or InBody body compositionBaseline lean mass and visceral fat distribution; tracks lean-mass preservation during therapy

If labs surface confounders (subclinical hypothyroidism, hypogonadism, B12 deficiency), we treat those first — often, weight starts moving before any GLP-1 is added.

Monitoring on Therapy

What gets checked and when.

04w

4-week check

Tolerability assessment, dose decision (escalate or hold), GI symptom audit. Telehealth.

12w

12-week labs

Repeat A1c, lipids, CMP. Body composition (DEXA or InBody). Adjust dose, titrate adjuncts.

24w

24-week review

Full re-evaluation. Are we hitting weight-loss target? Lean-mass preservation? Comorbidity remission?

52w

1-year strategy

Maintenance dose decision, taper-and-hold strategy, exit-plan refinement.

Patients on TRT or BHRT have hormones repeated every 12 weeks during the cut. Patients with diabetes have additional monitoring per ADA guidelines. Patients with prior pancreatitis history (a relative contraindication) have closer surveillance.

Special Populations

Cases that require extra thinking.

The Soft No

The patients we ask to start somewhere else.

Several patient profiles meet FDA criteria but get a different first-line recommendation from us:

None of these are permanent rejections. They are sequencing decisions. Sometimes the answer is "GLP-1 in three months, after we fix what's underneath."

Frequently Asked

Candidate selection, asked and answered.

I have Hashimoto's hypothyroidism. Am I disqualified?
No. Hashimoto's is not a contraindication. The MTC and MEN-2 contraindications refer specifically to medullary thyroid carcinoma — a rare cancer — and the genetic syndrome that predisposes to it. We screen family history at intake.
I had pancreatitis 10 years ago. Can I still do this?
Maybe. We review records, identify the cause (gallstones vs. alcohol vs. medication-induced vs. idiopathic), and discuss risk-benefit case-by-case. Single remote pancreatitis with a clear cause is often acceptable. Recurrent or recent pancreatitis is usually not.
Do you prescribe to patients without a high BMI?
Off-label prescribing for patients with BMI < 27 is rare and case-specific. We do not provide GLP-1s for cosmetic micro-weight-loss. Insurance will not cover, and the long-term risk-benefit calculation is unfavorable.
I'm pregnant — what about postpartum?
GLP-1s are contraindicated in pregnancy. Postpartum, we wait until breastfeeding has concluded (or the patient has chosen formula) before initiation. Pregnancy itself often shifts the metabolic picture; we re-evaluate everything 6 months postpartum.
I'm on Adderall / a stimulant. Does that change anything?
Stimulants suppress appetite. Adding a GLP-1 produces compounded appetite suppression and increased risk of inadequate caloric/protein intake. We can prescribe but typically dose conservatively and monitor protein adequacy carefully.
My family doctor prescribed it but won't manage it. Can you take over?
Yes, frequently. Transfers of care for GLP-1 management are routine. We obtain prior records, redo baseline labs (often we add tests primary care did not order), and continue therapy with our monitoring protocol. New-patient consultation is in-person at our Dalton clinic; subsequent visits can be telehealth across Georgia.
What does this cost out-of-pocket?
Drug cost is paid through your pharmacy and varies by insurance, manufacturer savings programs, and current pricing. The Limitless clinical management — consultation, labs, follow-up, peptide and hormone adjuncts — is membership-based or per-visit. Founding members lock pricing for 24 months. We provide a transparent quote during the consultation.

Editorial note. This article describes the candidate-selection framework Limitless Performance Medicine uses for GLP-1 / GIP therapy as of May 2026. All listed contraindications and screening recommendations follow current FDA labeling and standard endocrinology practice. Nothing here is a prescription or diagnosis. Individual decisions about weight-loss therapy require physician evaluation, lab work, and ongoing monitoring.

The right starting line is not the same for everyone.

Our consultation answers the candidate question on the basis of your labs, history, and goals — not a Google quiz. If a GLP-1 is right for you, we prescribe and monitor. If something else is the right first lever, we say so.
