What You Might Experience:
- Appetite changes: Many people report feeling full faster or having less interest in food within a few days.
- Mild nausea or bloating: These are common and often pass as your body adjusts.
- Energy shifts: Some feel more energized from eating less, while others may feel slightly tired.
✅ Tip: Stay well hydrated and eat smaller, more frequent meals to ease digestion.
Week 2: Adjusting to the Medication
By the second week, your body is beginning to adapt. You might start to notice more consistent appetite suppression and small changes in your eating habits.
Possible Developments:
- Weight changes: Some users begin losing a few pounds due to reduced calorie intake.
- Improved portion control: You may feel satisfied with less food and fewer cravings.
- Mild GI side effects: Nausea, burping, or constipation can still occur but are usually manageable.
✅ Tip: Avoid greasy or heavy foods which can trigger nausea. Stick to protein-rich meals and whole foods.
Week 3: Seeing Early Progress
By week 3, the medication is often working more effectively. You may find your food preferences shifting and your overall calorie intake significantly lower than before.
What You Might Notice:
- Weight loss of 3–7 lbs (1.5–3 kg) is not uncommon by this point.
- Steadier energy levels as your blood sugar stabilizes.
- Better food awareness and less emotional eating.
✅ Tip: Start tracking your progress in a journal or app—weight, mood, appetite, energy levels, etc.
Week 4: Building a Routine
By the end of your first month, you’ll likely feel more comfortable with the injection process and your body’s response to the medication.
Common Experiences:
- Improved satiety: Most people eat 30–50% less without feeling deprived.
- Confidence boost: Early success on the scale can be highly motivating.
- Side effects diminish: Nausea, if present, tends to lessen or resolve entirely.
At this point, your doctor may assess whether to increase your dose to 5 mg for continued progress, depending on how your body has responded.
✅ Tip: Don’t rush to increase your dose. Let your body fully adjust before moving up.

It’s important to remember that side effects vary from person to person. Here are some you may experience:
