Wegovy starts at 0.25 mg once weekly, increasing every 4 weeks through 0.5, 1.0, 1.7 to 2.4 mg (maintenance). Common side effects typically ease as doses rise gradually. Wegovy is not suitable in pregnancy and may be unsuitable with certain medical conditions—your clinician will advise.
Mounjaro is generally well-tolerated, but as with all medications, side effects can occur. The most common are mild to moderate and typically improve over time as your body adjusts. They include:

Here's how you can expect your journey to go
Everyone’s story is different, and that’s exactly how it should be. We’re here to make sure you never walk it alone.
In the first month, your body adjusts to GLP-1 as doses increase gradually (titration). Appetite often reduces within weeks, though weight loss may be modest. Mild side effects such as nausea are common but usually ease. The main goal is safe tolerance and preparing for steady progress.

Visible Weight Loss and Momentum
By three to six months, many see 5–10% weight loss. Reduced appetite makes smaller portions natural, and clothes begin to fit differently. Confidence grows as progress becomes visible, while healthy behaviours start to feel easier to maintain consistently with support from coaching and the app.

Early side effects typically settle as your body adjusts.

Frequently Asked Questions
Got questions about Wegovy? We've got all the answers for you here
What is Wegovy?
Wegovy (semaglutide) is a FDA-approved drug in a class of medications called glucagon-like peptide-1 receptor agonists (GLP-1s for short). Wegovy is clinically proven to help with weight loss. In a clinical trial, people who combined Wegovy with lifestyle changes lost an average of 15% of their body weight on average in 1 year.
How do you take Wegovy?
Wegovy comes in a prefilled injection pen. You administer the injection under the skin of your stomach, thigh, or arm once a week. While a routine injection may sound intimidating, the Wegovy pen uses a tiny needle designed to minimize discomfort. You’ll also receive clear instructions on using the injection pen, and your Weightless support team can offer additional advice.
What is Wegovy’s dosing?
Wegovy dosing starts out low, then gradually increases over the first few months until a steady dose is reached. If prescribed, a clinician will work with you to find the schedule and dosing that’s right for you. As an example, your provider may start you out on the lowest dose, 0.25 mg injected once weekly for the first month and slowly ramp you up to the maximum dose of 2.4 mg once weekly over the course of several months. This will depend upon your specific situation and your provider’s guidance.
How quickly do people lose weight with Wegovy?
In the STEP 4 clinical trial, people who combined Wegovy with a healthy diet and exercise lost an average of over 4% of their body weight by eight weeks. Those who reached a steady dose of 2.4 mg per week lost an average of 10.6% of their body weight in the first 20 weeks of treatment—and over 17% of their body weight within 68 weeks. Everyone responds to Wegovy differently, and if prescribed, your Weightless support team will work with you to get the best results for you.
