Start with what people ask most

Confused by all the GLP-1 noise? You're not alone — start with the questions everyone asks.

What is a GLP-1 medication?
GLP-1 drugs (like Ozempic and Wegovy) mimic a natural hormone that regulates appetite and blood sugar. They reduce hunger signals, slow digestion, and produce significant weight loss in most users.
Are GLP-1s safe?
For most people, yes — but it's a smart question to ask. Serious side effects like pancreatitis are rare; the common ones are nausea and stomach upset during the first weeks, and they usually fade. Your prescriber screens your history first — that screening is the safety system working.
How much does a GLP-1 cost per month?
Brand-name GLP-1s cost $900–$1,350/month without insurance. Telehealth programs with compounded semaglutide run $149–$399/month. Insurance coverage varies widely — many plans cover GLP-1s for diabetes but not weight loss.
What are the side effects?
The most common side effects are nausea, vomiting, and diarrhea — especially during dose escalation. Most improve after 4–8 weeks. Serious side effects (pancreatitis, thyroid risk) are uncommon but real.
Am I eligible for GLP-1 medications?
You likely qualify if your BMI is 30+, or 27+ with a weight-related condition like high blood pressure, prediabetes, or sleep apnea. Eligibility is broader than most people realize.
Which GLP-1 program is best?
It depends on your budget, insurance, and how much support you want. Ro Body leads for insurance navigation; Found for medication flexibility; Hims/Hers for lowest upfront cost. We've scored all 9 providers.
How long until I see results?
Most people lose 2–4 lbs in month 1 as doses are lowest. By month 3 results accelerate. Clinical trials show 10–15% body weight loss over 68 weeks on semaglutide at full dose.
Does insurance cover GLP-1s?
Coverage depends heavily on your plan and diagnosis. Most plans cover GLP-1s for type 2 diabetes (Ozempic, Mounjaro). Coverage for obesity/weight loss (Wegovy, Zepbound) is improving but still inconsistent.
What happens when I stop taking it?
Most people regain a significant portion of lost weight after stopping — studies show two-thirds regain within a year. Tapering slowly, maintaining protein intake, and strength training can help limit regain.

How GLP-1 medications work

GLP-1 receptor agonists mimic a natural hormone your body already produces. Here's what they do, in three steps.

01

Reduce appetite signals

GLP-1 medications act on receptors in the brain's hypothalamus, reducing hunger and food cravings. Most patients report a significant decrease in the mental "noise" around food.

02

Help you feel full longer

They slow how quickly food leaves your stomach, so your body tells your brain "I'm satisfied" sooner — and you simply eat less without white-knuckling it.

03

Steady your blood sugar

Steadier blood sugar means steadier energy and fewer cravings between meals — a quieter background hum instead of the constant pull toward food.
