Key Takeaway
What is the average weight loss on semaglutide 1.7mg? Learn about realistic results at this dose level, clinical trial data, and how 1.7mg compares to other semaglutide doses.
The average weight loss on semaglutide 1.7mg is approximately 10 to 13% of body weight when patients stay at or pass through this dose level during the standard titration period. For a 220-pound person, that translates to roughly 22 to 29 pounds. This dose sits just below the full maintenance dose and delivers substantial appetite suppression and metabolic improvement.
Where 1.7mg Fits in the Dosing Schedule
Semaglutide 1.7mg is the fourth step in the five-dose titration ladder used in the Wegovy clinical program. Patients typically reach this dose at week 13 and remain on it through week 16 before potentially moving to 2.4mg.
By the time patients arrive at 1.7mg, they have already been on semaglutide for three months. Their GI systems have adapted to the medication, appetite suppression is well established, and meaningful weight loss is already underway. The 1.7mg dose amplifies these effects and brings patients close to the full therapeutic ceiling.
1.7mg delivers 71% of the maximum 2.4mg dose. In pharmacological terms, the dose-response curve for semaglutide begins to flatten at higher doses, meaning much of the medication's weight loss effect is already active at 1.7mg.
Clinical Trial Weight Loss Data
The STEP trials did not publish separate endpoint results for the 1.7mg dose because it was a transitional step, not a maintenance dose. But we can extract useful data from the weight loss curves published in the trial results. For a complete cost breakdown, see our cheapest GLP-1 without insurance.

| 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 |
Weight Loss Trajectory at Week 16 (When 1.7mg Ends)
In STEP 1[1], the published weight loss curve shows that by week 16, when participants were completing their time at 1.7mg, average weight loss was approximately 10 to 11% of baseline body weight . This means:
- A 200-pound patient had lost roughly 20 to 22 pounds
- A 250-pound patient had lost roughly 25 to 28 pounds
- A 300-pound patient had lost roughly 30 to 33 pounds
Patients Who Stayed at 1.7mg
Real-world data from prescribers who maintain patients at 1.7mg as a long-term dose (rather than titrating to 2.4mg) suggest that final weight loss plateaus around 11 to 14% for most individuals over 6 to 12 months . This is lower than the 14.9% average at 2.4mg from STEP 1, but still represents clinically significant weight reduction that exceeds most other available medications.
Comparison Across Dose Levels
| Semaglutide Dose | Approximate Weight Loss (% of body weight) | Approximate Pounds Lost (220 lb patient) |
|---|---|---|
| 0.25mg (4 weeks) | 1 to 3% | 2 to 7 lbs |
| 0.5mg (4 weeks) | 3 to 5% | 7 to 11 lbs |
| 1.0mg (4 weeks) | 5 to 8% | 11 to 18 lbs |
| 1.7mg (4+ weeks) | 10 to 13% | 22 to 29 lbs |
| 2.4mg (maintenance) | 14 to 17% | 31 to 37 lbs |
What Drives Individual Variation at 1.7mg
Not everyone loses the same amount at 1.7mg. Several factors explain the spread in results:
Check your GLP-1 eligibility
Use our free BMI Calculator to see if you may qualify for provider-reviewed GLP-1 therapy.
Try the BMI Calculator →- Starting weight: Patients with higher baseline BMI tend to lose more total pounds but may see a similar percentage loss
- Dietary adherence: Semaglutide reduces appetite, but patients who also focus on protein intake and caloric awareness tend to outperform those who don't
- Physical activity: Adding 150 or more minutes of moderate exercise per week amplifies weight loss at every dose level
- Metabolic health: Patients with type 2 diabetes tend to lose less weight than non-diabetic patients on the same dose, likely due to insulin's fat-storage effects
- Duration at 1.7mg: Patients who remain at 1.7mg for 8 to 12 weeks instead of the standard 4 weeks often achieve more weight loss at this dose than those who titrate up quickly
- Genetics: GLP-1 receptor polymorphisms and individual gut hormone profiles influence how strongly a person responds to semaglutide at any dose
Maximizing Your Results at 1.7mg
If you're at the 1.7mg dose, here are evidence-based strategies to get the most from it:
- Prioritize protein: Aim for 30 grams of protein per meal. This preserves muscle mass and enhances the satiety effects of semaglutide protein recommendations on semaglutide
- Control portions even when not hungry: At 1.7mg, appetite suppression is strong. Make sure you're still eating enough to meet nutritional needs (at least 1,200 calories per day for women, 1,500 for men)
- Add resistance training: Weight training 2 to 3 times per week helps preserve lean muscle mass, which is critical for long-term metabolic health during rapid weight loss
- Track your progress weekly: Weigh yourself on the same day each week under similar conditions. A weekly average smooths out daily fluctuations
- Stay hydrated: Aim for at least 64 ounces of water daily. Dehydration can stall weight loss and worsen constipation, a common side effect at this dose

Frequently Asked Questions
- Is 1.7mg of semaglutide a high dose?
- It's the second-highest dose in the Wegovy titration schedule. At 1.7mg, you're receiving 71% of the maximum dose and most of the medication's appetite-suppressing and metabolic effects are already active.
- How much more weight will I lose if I go from 1.7mg to 2.4mg?
- On average, patients who titrate from 1.7mg to 2.4mg lose an additional 3 to 5 percentage points of body weight over the following months. For a 220-pound patient, that could mean an extra 7 to 11 pounds. Individual results vary significantly. semaglutide 2.4mg weight loss average
- I am losing weight well at 1.7mg. Should I still increase?
- Not necessarily. If your current rate of weight loss is meeting your goals and you're tolerating the medication well, staying at 1.7mg is a valid option. Discuss your trajectory with your prescriber.
- Why did my weight loss slow down at 1.7mg?
- Weight loss naturally decelerates as your body adapts to a lower caloric intake and your metabolic rate adjusts to your smaller body size. This isn't a sign of medication failure. It's a normal physiological response. Increasing activity or refining dietary habits may help restart progress.
- Can I stay at 1.7mg permanently?
- Yes. There's no requirement to reach 2.4mg. Many prescribers maintain patients at 1.7mg long-term when the dose provides adequate weight management and metabolic improvement. semaglutide 1.7mg how long to stay on
