✅ Top Benefits of Protein

1. Builds and Repairs Muscle

• Essential for muscle growth, repair, and recovery — especially after exercise or injury.

2. Supports Weight Loss and Management

• Increases feelings of fullness, reducing hunger and calorie intake.
• Helps preserve lean muscle mass during weight loss.

3. Boosts Metabolism

• Protein has a higher thermic effect (your body burns more calories digesting it compared to carbs or fat).

4. Strengthens Bones

• Protein-rich diets are linked to better bone density and reduced risk of osteoporosis, especially in older adults.

5. Supports Immune Function

• Helps form antibodies and other immune system components.

6. Maintains Skin, Hair, and Nails

• Structural proteins like collagen and keratin are essential for healthy appearance.

7. Hormone Production

• Protein is needed to produce important hormones like insulin, growth hormone, and others.

8. Aids in Enzyme Function

• Enzymes (which drive nearly all chemical reactions in your body) are made of protein.

9. Stabilizes Blood Sugar

• Protein slows down the absorption of sugar, helping prevent blood sugar spikes.

💡 How Much Do You Need?

• General adult: ~0.8g per kg of body weight
• Active people: 1.2–2.2g/kg
• Older adults: May need more to prevent muscle loss
