Key points
Before you start, a provider runs a medical evaluation, in person or by telehealth, covering your health history, current medications and weight goals. Some providers order blood work to check metabolic markers.
Once you are approved, most telehealth programs ship the medication to your home.
Your first dose is the lowest available strength so your body can adjust gradually. Unsure whether you are eligible?

Read full altRx reviewFor most patients, week two is when reduced appetite becomes hard to miss. Leaving food on your plate may feel strange at first, and portions that once seemed normal start to feel like too much.
Many people say cravings for particular foods, such as sweets and processed snacks, fade sharply.
If nausea lingers, bland, protein-rich foods and good hydration usually help. Our guide to what to eat on GLP-1 medication has specific meal ideas.
The cheapest published plans, sorted from lowest price, with the terms listed under every price.
Many patients lose 3-5 pounds by the end of the first month, but the range is wide: some lose more, some less. The scale is only one signal.
Looser clothes, steadier energy and a calmer relationship with food are just as meaningful early on.
Keep in mind that you are still on the starting dose. Most of the speed-up in weight loss comes in later months as the dose increases.
GLP-1 medication is prescription-only: a licensed clinician has to decide it is appropriate, and it is not a fit for everyone. Side effects are possible, and they tend to show up in the first few weeks while your body adapts.
Results are usually best when the medication is paired with simple daily habits, such as balanced meals and regular movement.
For both safety and lasting progress, pick a provider that screens you properly before prescribing and keeps following up once treatment starts.
Month one is about laying groundwork, not a dramatic change. The medication needs time to build to effective levels, and the dose rises slowly on purpose.
The patients with the strongest long-term results pair medication with lasting lifestyle habits: regular movement, enough sleep, stress management and balanced eating.
To set up a routine, see how to exercise on GLP-1 medication. The medication makes these habits far easier to keep; it does not replace them.
