Dosing at Four Months
By week 16, most semaglutide patients are at 1.7 mg weekly (Wegovy dosing) or approaching the 2.0 mg maximum (Ozempic dosing) . This is a critical inflection point because:
- 1.7 mg is the second-to-last step on the Wegovy ladder
- Appetite suppression at this dose is considerably stronger than at 1.0 mg
- Metabolic effects on blood sugar and lipids are near their peak
- Weight loss rate is accelerating compared to earlier months

Four-Month Results Data
| Outcome | Typical Range at 4 Months |
|---|---|
| Total weight loss | 14 to 22 pounds |
| Body weight percentage lost | 6% to 9% |
| Waist circumference reduction | 2.5 to 4 inches |
| Systolic blood pressure change | 5 to 10 mmHg decrease |
| Triglyceride change | 10% to 20% decrease |
| Current dose | 1.7 mg weekly |
The STEP 1 trial showed approximately 8% to 9% body weight loss at week 16, with patients on the semaglutide 2.4 mg track . Patients at 1.7 mg are slightly behind that pace but well within the expected range, with additional weight loss expected as they reach the maintenance dose.
Side Effects at Four Months
Most patients are well-adapted to semaglutide by month four, but the 1.7 mg dose can bring some new considerations :
- Nausea: Brief recurrence with dose increase, typically resolving in 2 to 3 days.
- Constipation: May require ongoing management. Consider a fiber supplement plus 80+ ounces of water daily.
- Fatigue: Caloric deficit from reduced appetite can cause low energy. Ensure you are eating enough protein and healthy fats.
- Hair thinning: If present, it usually peaks around months 3 to 5 and resolves on its own. Biotin and a balanced diet support hair health.
- Muscle loss: Without adequate protein and resistance training, weight loss can include lean muscle mass. This is preventable with proper nutrition and exercise.
Strategies for Month Four Success
- Push protein to 100 to 120 grams daily. As your appetite decreases further, each meal needs to prioritize protein.
- Strength train consistently. At least 3 sessions per week focused on major muscle groups.
- Schedule a body composition scan. DEXA or InBody scans reveal whether you are losing fat vs. muscle.
- Review your supplement stack. At minimum: multivitamin, vitamin D, omega-3, and potentially collagen peptides.
- Set new goals. You have likely surpassed your initial goals. Work with your provider to set the next milestones Form Blends telehealth consultation.
