Protein is often called the “building block of life,” and for good reason. It plays a crucial role in building, repairing, and maintaining tissues in your body including muscles, bones, skin, and hair. But according to Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford Universities, many people underestimate the impact of low protein intake on their overall health.

In a September 26 Instagram post, Dr. Sethi highlighted that without sufficient protein, your body’s metabolism slows down, increasing the risk of weight gain. He explained that protein is not only essential for maintaining muscle mass but also plays a key role in regulating blood sugar levels, energy, and even mood.

Why Protein Matters for Weight and Energy

Dr. Sethi emphasized that protein helps maintain the body’s burn rate. Without it, metabolism slows, making it easier to put on extra weight. He further added that low protein can cause dips in blood sugar, which trigger cravings for sugary foods and result in fatigue throughout the day.

To stay healthy and maintain energy, he recommends consuming at least one gram of protein per kilogram of body weight daily, ideally spread across three meals.

6 Signs You’re Not Getting Enough Protein

In his video, Dr. Sethi listed six warning signs that indicate protein deficiency:

1. Cravings for sugary foods – A lack of protein causes blood sugar dips, leading to an increased desire for sweets.
   
   

2. Constant fatigue – Insufficient protein intake may cause blood sugar drops, leaving you feeling drained throughout the day.
   
   

3. Unexplained weight gain – Without enough protein, your metabolism slows, which can result in unwanted weight gain.
   
   

4. Weak immunity – Frequent colds and flu-like symptoms could mean your immune system is weakened due to low protein levels.
   
   

5. Hair and nail problems – Grittiness or brittleness in hair and nails can signal protein deficiency.
   
   

6. Mood swings – Protein is essential for neurotransmitter production (like serotonin and dopamine), and a lack of it can lead to irritability or mood changes.
   
   

Bottom Line

Protein is more than just a nutrient for muscle growth it’s essential for metabolism, immunity, mood, and overall well-being. If you’re experiencing fatigue, frequent illnesses, or cravings for sugar, it may be time to evaluate your protein intake.

Dr. Sethi advises aiming for a balanced diet with adequate protein to avoid these health issues and maintain long-term wellness.
