Why Weight Loss on GLP-1 Takes Time

GLP-1 medications work by:

• Reducing appetite
• Slowing digestion
• Improving blood sugar control

This leads to steady and sustainable weight loss, not rapid crash dieting.

Week-by-Week GLP-1 Timeline

Week 1: Getting Started

• Mild side effects (like nausea) may begin

No major weight loss yet—this phase is about adjustment.

• Slight drop in weight (water + calorie reduction)

You may lose 0.5–1 kg, depending on diet.

---

Weight loss becomes more noticeable.

What Affects Your Results?

Not everyone loses weight at the same speed.

Key factors:

• Diet quality
• Protein intake
• Physical activity
• Dosage progression
• Sleep and stress

GLP-1 is a tool—not a magic solution.

---

Common Mistakes That Slow Progress

• ❌ Eating too little (causes fatigue)
• ❌ Skipping protein
• ❌ No physical activity
• ❌ Expecting instant results

---

When Do Results Slow Down?

Weight loss may slow after 3–4 months due to:

• Body adaptation
• Reduced calorie deficit

This is normal and called a plateau.

---

How to Maintain Progress

• Increase protein intake
• Add light strength training
• Adjust calorie intake carefully
• Stay consistent

---

The Takeaway

GLP-1 weight loss is:

• ✔ Gradual
