What is Protein and Why is It Important?
A macronutrient, protein is composed of amino acids, which are sometimes referred to as the "building blocks of life."
It has a role in many body processes, such as:
• Muscle Growth & Repair: Microtears are sustained by muscle fibers during physical activity, particularly resistance training. Muscle growth results from protein's assistance in their repair and reconstruction.
• Enzyme and Hormone Production: A large number of protein-based enzymes and hormones, including growth hormone and insulin, control essential body processes.
• Immune Function: Proteins aid in the production of immune cells and antibodies, which guard against illnesses and infections.
• Cellular Structure & Repair: Protein is essential for the maintenance of the structure and functionality of skin, hair, nails, and organs.
• Nutrient Transport: Hemoglobin and other proteins carry oxygen throughout the blood, guaranteeing healthy cellular activity.
è “Protein is more than just a nutrient; it is the foundation of life, enabling countless biological processes to keep you healthy and strong.”
How to calculate your ideal protein intake?
You can use this easy formula to figure out how much protein you need:
1. First convert your weight from pounds to kilograms. So divide it by 2.205.
For Example, A person weighing 150 pounds = 68 kgs.
2. Multiply your weight (kg) by the recommended protein range:
1.0 g/kg for a sedentary lifestyle.
1.2–1.5 g/kg for a moderately active lifestyle (light exercise three–four times per week).
1.6–2.0 g/kg for a very active lifestyle (intense exercise five–seven times per week).
For example, for a person weighing 150 pounds (68 kg) and moderately active:
(68 kg × 1.4 g, moderate activity) = 95 g of protein per day
How much protein you need by age and weight?
Age, fitness objectives, and degree of activity all affect how much protein is
essential. This is the amount you should strive for:
Typical Daily Suggestions
Based on body weight and gender, health organizations like the National
Academy of Medicine suggest a baseline protein intake:
46 grams per day for female
56 grams daily for males
(The average sedentary adult with little physical activity is represented by these values.)
Protein Intake by Age (General Recommendations)
Children (4–13 years): 0.95 g per kg of body weight
Teenagers (14–18 years): 0.85 g per kg
Adults (19–64 years): 0.8 g per kg
Older Adults (65+ years): 1.0–1.2 g per kg (to prevent muscle loss)
Individualized Protein Requirements: There is no one-size-fits-all protein intake. Individual needs are influenced by various factors:
1. Age and Life Stage
- Children and Teens: Growth and development require higher protein intake.
- Older Adults: As people age, their muscle mass naturally decreases, so maintaining strength and preventing muscle loss require a high protein intake.
2. Health and Fitness Objectives
- Muscle Gain: Strength training in conjunction with higher protein promotes hypertrophy, or muscle growth.
- Weight Loss: By maintaining lean muscle mass and promoting satiety, or feeling full, protein can aid in weight loss.
3. Dietary Restrictions & Preferences
- Vegans and vegetarians: Must make sure they consume a variety of plant-based foods, such as legumes, nuts, and soy products, to ensure they get adequate protein.
- People with Medical Conditions: People with metabolic diseases or kidney disease may need to consume different amounts of protein.
- Pregnant & Breastfeeding Women: Increased protein supports fetal development and milk production.
- Elderly Adults: More protein can help prevent sarcopenia (age-related muscle loss).
- Individuals Recovering from Illness or Injury: Protein is essential for tissue repair and recovery.
- Athletes and Active People: Your needs for protein rise if you lead a physically demanding lifestyle or engage in regular exercise. According to the International Society of Sports Nutrition,
- For active people : 1.4 to 2.0 grams per kg of body weight.
- Power and Strength Weightlifters, sprinters, and other athletes: 1.6–2.0 g/kg
- Endurance athletes: 1.2–1.4 g/kg (runners, cyclists, etc.) For example, you might require 112–140 grams of protein per day if you lift weights and weigh 70 kg (154 lbs).

How Much Protein is Too Much?
Although protein is necessary, too much of it can put stress on the kidneys and liver, particularly in those who already have health issues.
Indications That You're Eating Too Much Protein
- Digestive Problems: diarrhea, constipation, or bloating
- Dehydration: The risk of dehydration increases because protein metabolism needs more water.
- Kidney strain: Overconsumption of protein can eventually cause kidney strain.
- Nutrient Imbalance: If carbohydrate intake is too low, an excessive protein intake may result in a decreased fiber intake.
- Up to 2.2g per kg is considered safe for athletes.
- Above 3.0g per kg may lead to health issues long-term.
Are You Getting Enough Protein?
Many people don't realize how much protein they need. These are typical
indicators of a deficiency:
Indications Your Protein Intake Is Inadequate
- Weakness and Fatigue of the Muscles: Strength loss and a delayed recovery
- Brittle Nails & Hair Thinning: Protein promotes the growth of both hair and nails.
- Regular Illnesses: Immune system weakness
- Hunger & Cravings: Protein controls hunger
- Slow wound healing: Protein is necessary for tissue repair
è Solution: If you notice these symptoms, increase your consumption of foods high in protein (see the list below)
Top 10 Protein Rich Foods
Animal-Based Proteins
1. Eggs – 6g per egg (Complete protein)
2. Chicken Breast – 31g per 100g
3. Salmon – 25g per 100g + Omega-3s
4. Lean Beef – 26g per 100g
5. Greek Yogurt – 10g per 100g

Pro Tip: Combine grains and legumes (e.g.,
rice + beans) for a complete amino acid profile.
Select high-quality sources of protein, including both plant-based and
animal-based sources.
Steer clear of too much protein to avoid nutrient imbalances and kidney stress. If you're unsure about your ideal protein intake, consult a healthcare professional or registered dietitian to tailor a plan that fits your lifestyle.
