Key Takeaway
Average weight loss on liraglutide 0.6mg. Covers realistic expectations at the starting dose, why significant weight loss doesn't occur at this level, and what to expect as you titrate up.
Average weight loss on liraglutide 0.6mg during the first week of treatment is 0 to 2 pounds. This isn't clinically significant weight loss, and it isn't expected to be. The 0.6mg dose is an introductory titration step, not a therapeutic dose for weight management. Any weight change at this level reflects reduced food volume and water fluctuations rather than meaningful fat loss. The real weight loss begins as you titrate upward toward the 3.0mg target dose.
Why Weight Loss Is Minimal at 0.6mg
Liraglutide works by activating GLP-1 receptors in the brain and gut, reducing appetite and slowing digestion. At 0.6mg, the level of receptor activation is low enough that the weight loss effect is barely detectable:
- The therapeutic dose for weight management (Saxenda) is 3.0mg daily, five times the starting dose
- Even the diabetes dose (Victoza) uses 1.2mg to 1.8mg, which is two to three times the starting dose
- At 0.6mg, the appetite-reducing signal is present but weak. Most patients still feel hungry at meal times.
- The gastric-slowing effect is minimal, so food moves through your system at near-normal speed
Think of 0.6mg as the warm-up lap before the race. The effort isn't wasted, but the results come later.
What the Scale Shows During Week 1
Based on clinical data and prescriber experience, the first week at 0.6mg typically produces:

| Category | Mean Body Weight Loss (%) | Detail |
|---|---|---|
| Tirzepatide | 22 | ~22% body weight at 72 wks |
| Semaglutide | 15 | ~15% body weight at 68 wks |
| Liraglutide | 8 | ~8% body weight at 56 wks |
| Retatrutide | 24 | ~24% in Phase 2 trial |
| Scenario | Approximate Weight Change | Frequency |
|---|---|---|
| No change | 0 lbs | ~40% of patients |
| Mild loss | -1 to -2 lbs | ~45% of patients |
| Slight gain | +1 to +2 lbs | ~15% of patients |
A slight gain isn't a bad sign. Normal weight fluctuations (water, sodium, menstrual cycle, bowel content) easily account for 1 to 2 pounds in either direction. This has nothing to do with the medication's effectiveness.
Putting 0.6mg in Context: The Full Treatment Picture
The real weight loss numbers come from the full-dose treatment period. Here is the trajectory patients can expect as they titrate:

|---|---|---|
| 0.6mg | 1 week | 0-2 lbs lost |
| 1.2mg | 1 week | 1-2 lbs lost |
| 1.8mg | 1 week | 1-3 lbs lost |
| 2.4mg | 1 week | 2-3 lbs lost |
| 3.0mg (months 2-6) | Ongoing | 4-8 lbs/month |
Over a full year at the 3.0mg target dose, the SCALE trial[1] showed average weight loss of approximately 8 percent of starting body weight, with some patients losing 10 percent or more. liraglutide 1.2mg weight loss average
Should You Track Weight During Week 1?
We recommend taking a baseline weight on the morning of your first injection and then not weighing yourself again until the end of week 1 or even week 2. Daily weighing during the 0.6mg phase can create unnecessary frustration:
- Normal daily fluctuations of 1 to 3 pounds mask any medication effect
- Seeing "no change" or slight gains can feel discouraging, even though they're completely normal
- Early fixation on the scale can set an unhealthy pattern for the rest of treatment
Instead, focus on adapting to the injection routine, managing any side effects, and building the eating and hydration habits that will support your weight loss at higher doses.

Frequently Asked Questions
- Should I be concerned if I don't lose any weight at 0.6mg?
- Not at all. Zero weight loss at 0.6mg is the most common outcome and says nothing about how you'll respond at therapeutic doses. The medication needs time and dose to reach its full effect.
- I lost 4 pounds in my first week on 0.6mg. Is that normal?
- Above-average first-week loss is possible, especially if you also made dietary changes or if you had significant water retention before starting. This early result doesn't necessarily predict faster-than-average long-term results, but it's a positive start.
- How does liraglutide 0.6mg weight loss compare to tirzepatide 2.5mg?
- Both are introductory doses, but tirzepatide 2.5mg (injected weekly) tends to produce slightly more noticeable appetite suppression than liraglutide 0.6mg (injected daily). At their respective therapeutic doses, tirzepatide produces significantly more weight loss than liraglutide. tirzepatide vs liraglutide
- Can I speed up the titration to get to a dose that actually works?
- Some prescribers allow faster titration in patients who tolerate 0.6mg very well. But the standard weekly increases exist for good reason. Rushing to 3.0mg increases the risk of severe nausea and vomiting that could cause you to stop the medication entirely. Patience during titration usually pays off with better long-term adherence.
