Recommendation

The Recommended Dietary Allowance (RDA)
of protein varies throughout life

The Indian Council of Medical Research (ICMR) and the National Institute of Nutrition (NIN) have set the Recommended Dietary Allowance (RDA) for protein, ensuring that all population groups can achieve optimal health through balanced nutrition.

Table: Recommended Protein Requirements for Indians 2024 – ICMR-NIN

Additional protein requirement at 2nd and 3rd trimester over and above 0.66 g/kg/day for pregnant women with GWG of 10 kg and for lactating women are given. For GWG of 12 kg, see Table 5.2 in the Full version (https://www.nin.res.in/RDA_Full_Report_2020.html).

*For people consuming cereal-based diet with low quality protein, the protein requirements are 1 g/kg per day.

#Total protein required per day for 55kg body weights are given in column 3. For specific body weight one can calculate  from EAR column* that provides protein requirement for per kg body weight

$ Tolerable Upper Limits (TUL) indicates <15-40% of total energy from proteins.

Λ EAR: Pregnant women (during 2nd & 3rd Trimester) and lactating women (during 0-6 & 6-12 months) should additionally ake 7.6gm & 17.6gm and 13.6gm & 10.6gm of protein per day respectively.

Λ RDA: Pregnant women (during 2nd & 3rd Trimester) and lactating women (during 0-6 & 6-12 months) should additionally take  9.5gm & 22 gm and 17gm & 13gm of protein per day respectively. Additional protein recommendation of protein is for 10

Right Plan

Why Protein demands Are Personal

Your body’s protein needs aren’t static – they shift with your journey through life.

From childhood growth spurts to the golden years, from the demands of athletic performance to the recovery after illness or surgery, protein plays a starring role in keeping your body strong, resilient, and thriving.

Factors like age, physical activity, physiological changes (like pregnancy or ageing), and health conditions significantly influence how much protein your body requires. Whether it’s for building muscle, repairing tissues, boosting immunity, or simply staying energised, protein is the fuel behind the scenes.

For children, teens, expectant or nursing mothers, athletes, older adults, and those healing from illness, the demand is higher, and meeting these needs is key to long-term health and vitality.

Balanced Diet, Balanced Protein:
The Natural Approach to Meeting Your Need

For most healthy individuals, a well-balanced diet delivers
all the protein the body needs.

Animal-based foods like eggs, dairy, poultry, and fish are powerhouses of complete proteins.
On the plant side, nature offers an abundance – legumes, pulses, soy, whole grains, nuts, and seeds.
When paired wisely, these plant proteins come together to form a complete amino acid symphony, supporting strength, vitality, and overall well-being.

When Protein Needs a Boost:
Fuel the Gaps

There are times when reaching your protein goals through food just isn’t enough. Whether it’s due to increased physical demand (e.g., during intense physical training, growth spurts, or pregnancy), reduced appetite common in aging, illness, or post-operative phases), or dietary restrictions (e.g., veganism or food intolerances). These situations call for a little extra help to meet your nutritional needs.

That’s where protein supplementation steps in as a smart, supportive strategy. Whether it’s whey, casein, plant-based options, or specialised clinical nutrition formulas, these supplements help bridge the nutritional gap. They work behind the scenes to prevent muscle loss, strengthen immunity, speed up recovery, and maintain metabolic health. Understanding when and how to supplement starts with recognising the unique needs of each individual. While a food-first approach is always preferred, but when dietary sources fall short, supplements can offer targeted, measurable support to ensure optimal protein adequacy.

No More Protein Confusion

The Right Awareness of the Right Protein Plan
at the Right Time – Maximizes Impact

Protein requirements vary based on several key factors, including:

  1. Age: Older adults require more protein to prevent muscle loss and support bone health.
  2. Physical Activity: Active individuals or those who engage in intense exercise need more protein to support muscle repair and recovery.
  3. Medical Conditions: Conditions like surgery recovery, illness, or chronic disease may increase protein requirements.
  4. Lifestyle & Diet: If you follow a vegetarian or vegan diet, you may need to focus on plant-based protein sources to meet your nutritional needs.

    Check for certifications like FSSAI, NSF Certified for Sport, or third-party lab testing to ensure purity and label accuracy, essential for both athletic and clinical use
  4. Serving Size and Scoop Accuracy
    Ensure the scoop matches the listed serving size to avoid under or over-consumption.
Classification of Protein Deficiency
Lack of protein can be classified into two major forms – Kwashiorkor and Marasmus, each with its own story of struggle and symptoms.

Kwashiorkor:

  • Caused by severe protein deficiency despite adequate calorie intake.
  • Common signs – swelling (edema), low energy, irritability, and delayed growth.
  • Most Vulnerable – young children in areas with limited access to protein-rich foods.

Marasmus:

  • Caused by severe calorie and protein deficiency.
  • Common signs: Drastic weight loss, visible muscle wasting (as the body breaks down its own tissue for energy), and profound weakness.
  • Most Vulnerable: infants and young children in resource-limited settings.

How Severe is Your Protein Deficiency?

Protein deficiency isn’t one-size-fits-all – it’s measured in degrees. One of the most reliable indicators? Serum albumin levels, a vital marker that reflects the body’s protein status through the bloodstream.

  • Healthy range: Albumin levels between 3.5–5.0 g/dL signal balanced protein nutrition.
  • Mild Deficiency (3.0–3.4 g/dL)
    Subtle but serious – may cause fatigue, a weakened immune system, and slow muscle recovery. Often overlooked, but worth paying attention to.
  • Moderate Deficiency (2.5–2.9 g/dL)
    A deeper dip into deficiency – the body begins to show more obvious signs of imbalance, and health risks grow.
  • Severe Deficiency (<2.5 g/dL)
    Critical condition – marked by muscle wasting, drastic weight loss, and an increased risk of infections and other major health issues.

Low albumin levels can indicate poor protein intake or absorption and are commonly used in clinical settings to assess nutritional risk.

Common Signs (Across All Ages):

  • Edema (Swelling): Low protein levels disrupt fluid balance, leading to swelling in legs, feet, and hands.
  • Muscle Loss & Weakness: Inadequate protein intake causes the body to break down muscle for energy.
  • Weakened Immunity: Reduced antibody production and slower healing increase the risk of infections.
  • Hair, Skin, and Nail Problems: Thinning hair, brittle nails, and dry, flaky skin may result from poor protein intake.
  • Fatigue & Reduced Stamina: Low protein affects energy metabolism, leading to persistent tiredness and poor endurance.

Infants and Children:

  • Importance: Protein supports rapid growth, development, and a strong immune system in children.
  • Signs of Deficiency: Look outfor slowed growth, tiredness, trouble focusing, and a weakened immune system.
  • Recommendations: Ensure a balanced diet that includes age-appropriate protein intake through various sources like dairy, lean meats, and legumes in their diet.

ICMR 2024 Recommended Dietary Allowance (RDA):

  • 1–3 years: 12.5g/day
  • 4–6 years: 16g/day
  • 7–9 years: 23g/day

Adolescents & Young Adults:

  • Importance: Protein is essential for continued growth, hormonal changes, and muscle development during adolescence.
  • Signs of Deficiency: Look for delayed growth, muscle weakness, hair fall, frequent infections due to weakened immunity, and signs of anaemia such as fatigue, pale skin, or dizziness.
  • Recommendations: Include diverse protein sources like lean meats, dairy products, legumes, and nuts to meet growing needs.
  • ICMR 2024 Recommended Dietary Allowance (RDA):❖ Boys (10–18 years): 32-55g/day

    ❖ Girls (10–18 years): 33-46g/day

These values help support optimal physical and cognitive development during the adolescent years.

Adults:

  • Importance: Protein maintains muscle mass, supports metabolism, and aids tissue repair.
  • Signs of Deficiency: Watch out for signs like muscle loss, fatigue, and a weakened immune system.
  • Recommendations: Adults should aim for 0.8 grams of protein per kilogram of body weight daily, depending on activity level, as per ICMR guidelines.
  • ICMR 2024 Recommended Dietary Allowance (RDA):➢ Men: 54g/day

    ➢ Women: 46g/day

These requirements may increase depending on physical activity levels, health conditions, or during recovery from illness or surgery.

Senior Citizens:

  • Importance: With age, muscle loss (sarcopenia) is common, affecting mobility, bone strength, and independence. Protein is essential to preserve muscle, supports bone health, supports recovery, and preserves overall functionality.
  • Signs of Deficiency: Due to a lack of strength, there is a higher risk of falls, fractures, and slower recovery from illness.

Recommendations: Aim for 1 to 1.2 grams of protein per kilogram of body weight daily to maintain muscle health, as per ICMR guidelines.

❖ ICMR 2024 Recommended Dietary Allowance (RDA):
➢ Men 60+ years: 54g/day

➢ Women 60+ years: 46g/day
Small Protein Gap?

Be Alert. It Could Make a Big Impact!:

Protein fuels muscle repair, immunity, hormone regulation, and overall health. Even a small protein gap can have lasting effects, especially during critical stages of life.

During infancy, childhood, and adolescence, protein plays a vital role in growth, development, and immune health. A lack of protein in these stages can slow physical growth and impact brain development.

For the developing fetus, insufficient protein can hinder growth and raise the risk of complications such as preterm birth or low birth weight.

After birth, children are vulnerable to protein deficiency, leading to conditions like Kwashiorkor (swelling, lethargy) or Marasmus (wasting, stunted growth), often caused by diets low in protein despite high carbohydrate intake.

Marasmus is more common when calorie intake is severely limited, while Kwashiorkor is more linked to a lack of sufficient protein despite adequate calorie intake. This often occurs in diets based on carbohydrates (like rice or bread) without enough protein-rich foods like meat, dairy, legumes, or eggs. In many cases, home-cooked meals rich in carbs and low in protein can lead to insufficient protein intake, especially when transitioning from breastfeeding to solid foods.

Maintaining a protein-rich diet is essential for health at every stage of life.
While most individuals can meet their protein needs through a balanced diet, certain conditions can increase protein demands, making supplementation a valuable solution. These include:

  • Increased Physical Activity: Athletes or those in endurance/strength training need more protein for muscle recovery and growth.
  • Aging: Older adults may struggle to meet protein needs due to anabolic resistance and reduced appetite, leading to muscle loss (sarcopenia).
  • Acute Illness/Post-Surgical Recovery: The body demands a higher intake of protein during recovery, supporting wound healing and immune function.
  • Chronic illnesses: Conditions like cancer, COPD, heart failure, and liver disease can cause muscle wasting, requiring additional protein.
  • Renal Replacement Therapy: Dialysis patients lose amino acids and proteins during treatment and need higher protein intake from both food and supplements.
  • Malnutrition: Protein supplements help bridge dietary gaps in individuals with malnutrition or protein-energy malnutrition (PEM), particularly in clinical settings.
  • Pregnancy & Lactation: Increased protein needs for fetal growth and milk production may not always be met through food alone.
  • Post-Bariatric Surgery/GI Disorders: Conditions that limit protein intake or digestion, like reduced stomach capacity or malabsorption, may require supplements.
  • Poor Dietary Access/Food Aversion: Economic constraints, restrictive diets (e.g., veganism), or appetite loss (e.g., chemotherapy, depression) can reduce protein consumption.
  • Critical Care/ICU Patients: Aggressive nutritional support, including protein supplementation, is crucial to prevent muscle loss and support recovery
Indications and Benefits Across Stages:

During Physical Activity & Exercise:
How It Helps: Exercise causes tiny muscle tears, and protein helps repair them, speeding recovery, boosting growth, easing soreness, and enhancing performance.

Benefit: Ideal for athletes, fitness enthusiasts, and active lifestyles.

In Energy Deficiency (Low Carb Intake):

How It Helps: During low-carb diets or fasting, the body can use certain amino acids from protein as an alternative energy source. This makes protein supplementation crucial for maintaining energy levels.

Benefit: Supports low-carb lifestyles and fights fatigue from insufficient carbs.

For Vegetarians & Vegans:

How It Helps: Vegetarians & vegans may lack complete protein sources that provide all essential amino acids. Protein supplements, especially plant-based ones, help bridge this nutritional gap.

Benefit: Vital for vegetarians and vegans to get all essential amino acids for optimal health.

For Busy Lifestyles:
How It Helps: Protein supplements offer a quick, convenient fix for busy lives, irregular meals, or low protein intake.

Benefit: Ideal for busy professionals, travellers, and anyone needing a fast, efficient protein boost on the go.

During Recovery & Weight Management:

How It Helps: Protein supports muscle repair and tissue regeneration after illness, surgery, or injury. It also aids in weight management by enhancing fullness and preventing muscle loss during calorie restriction.

Benefit: Ideal for post-surgery recovery, injury healing, and preserving muscle during weight loss.
