While protein is essential for the body, excessive intake can strain the system and cause issues like constipation, thirst, bad breath, weight gain, and fatigue

Protein is essential for a healthy body, but consuming it in excess can lead to health issues. Clinical and sports nutritionist and diabetes educator Rajat Jain explains that while protein plays a vital role in building and repairing the body, too much of it can put unnecessary pressure on the system. Overconsumption can lead to symptoms such as constipation, constant thirst, bad breath, weight gain and fatigue. He also shared five signs of excessive protein consumption and their solutions.

Digestive Problems

Consuming too much protein, especially from animal sources, can lead to constipation or bloating, particularly if fibre intake is low.

Solution: Add fibre-rich foods such as vegetables, fruits and whole grains to your diet to support healthy digestion.

Constant Thirst

High protein intake puts pressure on the kidneys, which can cause dehydration and make you feel constantly thirsty.

Solution: Drink plenty of water and keep your protein intake within the recommended range which is 1.2–2 grams per kilogram of body weight.

Bad Breath

A diet high in protein and low in carbohydrates may push the body into a state of ketosis, where fat is used for energy. This process can cause unpleasant breath.

Solution: Balance your diet by including complex carbohydrates like oats and sweet potatoes.

Unwanted Weight Gain

While protein is important, it also contains calories. Overeating protein may result in excess calorie intake, which gets stored as fat.

Solution: Be mindful of your total calorie consumption and match your protein intake to your energy requirements.

Fatigue or Slow Recovery

A diet focused only on protein and lacking in carbohydrates or healthy fats can reduce energy levels and slow down muscle recovery.

Solution: Eat a well-balanced diet that includes the right mix of protein, fats and carbohydrates to support overall health.

Benefits of Protein

Protein plays a key role in building and repairing cells, supporting muscle strength, boosting metabolism, and enhancing immunity. It helps you feel fuller for longer, contributes to weight control, and promotes healthier hair, skin and nails. In short, consuming the right amount of protein supports an active and healthy lifestyle.

However, if you’re experiencing any of the symptoms mentioned above, it may be time to review your diet and ensure you’re not overdoing it. Moderation and balance are key to maintaining good health.
