This comprehensive guide explains the expected timeline for weight management using liraglutide, commercially available as Saxenda, and provides actionable strategies for monitoring progress and establishing realistic goals. Liraglutide, a glucagon-like peptide-1 receptor agonist (GLP-1), influences appetite regulation through pathways in the brain and gut. Essentially, it aids in diminishing hunger, promoting a feeling of fullness, and facilitating smaller portion sizes, which simplifies adherence to a reduced-calorie diet.
How Liraglutide Works
Liraglutide belongs to a class of medications that act on appetite-regulation pathways in the brain and gut. In plain terms, it may help reduce hunger, increase fullness, and support smaller portions, which can make a calorie-reduced plan easier to follow.
Initial Weeks: Subtle Changes and Dose Adjustment
Most people don’t feel dramatic changes overnight. During the first 1-2 weeks, many individuals report subtle changes in appetite and earlier satiety as their dose is gradually increased. During the first few weeks-especially while moving up the dose-expect small, gradual shifts in appetite and portions. Some people notice less snacking or fewer cravings in the evening.
Liraglutide is started low and increased stepwise to a maintenance dose. Mild, temporary digestive symptoms can occur as your body gets used to the medicine; your care team may suggest pacing your dose increases and simple diet adjustments to stay comfortable.
Early wins might look like one to three pounds off over a few weeks, steadier meal timing, or improved control around trigger foods.

Weeks 3-8: Noticeable Changes Begin
With consistent use and lifestyle alignment, noticeable changes-like easier portion control and a slow downward trend on the scale-often begin to appear. Some people starting losing weight in the first 2 to 4 weeks after starting treatment with Saxenda. In studies, significant weight loss of at least 5% was seen after 8 weeks of treatment.
Around 16 Weeks: Reassessment Point
Clinicians commonly reassess results at this point. If you have not lost at least 4% of your body weight at this time, your doctor may tell you to stop taking it. There are other options for weight loss, including different medicines and weight loss surgery.
Everyone responds differently to liraglutide. Your results may vary based on individual factors such as biology, nutrition, and lifestyle.
Long-Term Treatment: Sustaining Weight Loss
After one year of treatment in adults, 85% of patients treated with Saxenda lost weight (an average of 21 lb. [9.5 kg] weight loss, or 9.2% of their weight).
If you stop treatment with Saxenda you will likely regain your lost weight. However, research has shown that if you stay on treatment, your weight loss can be maintained.

Factors Influencing the Timeline
Several factors can influence how quickly you start seeing results.
Dose and Titration
Liraglutide is started at a low dose and gradually increased to a maintenance dose. During the first few weeks, especially while moving up the dose, expect small, gradual shifts in appetite and portions.
Diet and Exercise
Compounded liraglutide reduces appetite, but weight loss results also depend on your eating habits and physical activity. Those who follow a calorie-conscious diet and incorporate regular movement tend to see faster, more consistent results. Even small lifestyle changes-such as increasing protein intake or taking daily walks-can support weight loss and promote long-term success. Saxenda should be used in combination with a reduced calorie diet and regular physical activity.
Consistency in Medication Use
Taking compounded liraglutide daily, as prescribed, is key to achieving sustainable weight loss results. Missed doses or interruptions in treatment can slow progress. For the best results, stick with your medication schedule and maintain sustainable lifestyle habits that support your treatment.
Individual Response
Everyone responds differently to liraglutide. Your results may vary based on individual factors such as biology, nutrition, and lifestyle. Some people respond quickly to compounded liraglutide, while others see gradual progress. Factors like age, genetics, hormone levels, and metabolic rate all influence how quickly weight loss occurs. If results seem slow, it doesn’t mean compounded liraglutide isn’t working-it just may take longer for your body to adjust.

Maximizing Effectiveness
To maximize the effectiveness of your compounded liraglutide weight loss treatment, pair the medication with sustainable habits that support your body’s response to the medication:
- Be consistent with your injections: Taking compounded liraglutide at the same time every day helps maintain steady levels in your system.
- Follow a balanced, nutritious diet: Prioritize lean proteins, fiber-rich foods, and healthy fats to stay full and promote fat loss.
- Stay active: Aim for at least 150 minutes of movement per week to enhance results. Even a short daily walk can make a difference.
- Stay hydrated: Drinking plenty of water reduces nausea and supports digestion while taking compounded liraglutide.
- Check in with your provider: Regular check-ins allow for adjustments to your dosage and treatment plan, ensuring long-term success.
Potential Side Effects
Compounded liraglutide, like any medication, may cause side effects, especially during the first few weeks of use. Most are mild and temporary, improving as your body adjusts. Common side effects include:
- Nausea
- Vomiting
- Diarrhea or constipation
- Indigestion and bloating
- Fatigue
- Injection site reactions (mild redness, itching, or swelling)
If side effects feel severe or don’t improve over time, talk to your provider-they may adjust your dose or recommend ways to ease discomfort.
Comparing Liraglutide to Other Medications
Compounded liraglutide, semaglutide, and Tirzepatide are all GLP-1 medications, but they’re not identical. Each works differently and has its own dosing schedule, effectiveness, and FDA-approved uses for weight loss.
- Compounded Liraglutide: A once-daily injection, compounded liraglutide mimics the GLP-1 hormone to reduce appetite and slow digestion. It was the first GLP-1 medication approved for chronic weight management and typically leads to 5-10% total body weight loss over time.
- Semaglutide (Wegovy®): A more potent GLP-1 agonist, semaglutide is taken once weekly and results in higher average weight loss (10-15%) than compounded liraglutide. Wegovy® is specifically FDA-approved for weight loss.
- Tirzepatide (Zepbound®): This once-weekly injection is a dual agonist, targeting both GLP-1 and GIP receptors to enhance weight loss results. Studies show that Tirzepatide can lead to 15-20% total body weight loss.
Important Considerations
- Saxenda® (liraglutide) injection 3 mg is an injectable prescription medicine used for adults with obesity or overweight (excess weight) who also have weight related medical problems, and children aged 12-17 years with a body weight above 132 pounds (60kg) and obesity to help them lose weight and keep the weight off.
- Possible thyroid tumors, including cancer. Tell your health care professional if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer.
- Stop using Saxenda® and call your healthcare provider right away if you have severe pain in your stomach area (abdomen) that will not go away, with or without vomiting.
- Saxenda® can increase your heart rate while you are at rest.
- Diarrhea, nausea, and vomiting may cause a loss of fluids (dehydration) which may cause kidney problems. It is important for you to drink fluids to help reduce your chance of dehydration.
- Stomach problems, sometimes severe, have been reported in people who use Saxenda®.
- Call your health care provider right away if you have any mental changes that are new, worse, or worry you
- Saxenda® may increase the chance of food getting into your lungs during surgery or other procedures.
