Thairath Online explains how to calculate the right protein amount based on your lifestyle and age for sustainable good health.

Getting to know "protein" What is it?

Protein (Protein) is a major nutrient composed of various amino acids. It functions in building and repairing tissues throughout the body—from hair, skin, muscles to enzymes and immunity.

If protein is lacking, the body weakens, wounds heal slowly, and muscle mass decreases. Protein sources are mainly divided into two groups for nutritional variety:

1. Animal protein This protein contains all essential amino acids and is easily absorbed by the body.

• Meat: chicken breast, lean pork, beef
• Seafood: tuna, salmon, shrimp
• Eggs: an affordable and high-quality protein source
• Dairy products: fresh milk, yogurt, cheese

2. Plant protein A good option for vegetarians or those wanting to avoid cholesterol.

• Soy and soy products: tofu, soy milk, tempeh (fermented soybeans)
• Legumes: red beans, mung beans, almonds,pistachios
• Grains: quinoa, oats, brown rice
• Certain vegetables: broccoli, spinach

Why calculate "how many grams of protein to eat daily"?

Eating the correct amount of protein for your body directly affects metabolism and weight control. Protein helps you feel full longer, reduces snacking, and preserves muscle mass. Insufficient protein causes the body to draw from muscle, impairing metabolism and causing fatigue.

Summary: How to ensure adequate protein intake

• Divide meals: spread protein intake over 4-5 meals (20-30 grams each). Avoid consuming it all at once, as absorption may be incomplete.
• Eat protein first: chew meat fully before eating rice or vegetables.
• Use supplements: add whey protein or high-protein milk on days you eat less meat.
• Choose softer foods: alternate with fish, steamed eggs, or tofu, which are easier to eat than tough chicken breast.
• Carry snacks: keep boiled eggs or nuts handy to accumulate protein throughout the day.

How to calculate protein intake based on body weight and lifestyle

The basic formula recommended by nutritionists is" Body weight (kg) x desired protein amount "Divided according to activity levels as follows:

1. General population

Those mainly working office jobs with little exercise.

• Calculation: Body weight (kg) x 0.8 - 1.0
• Example: A 60 kg person should consume about 48-60 grams of protein daily.

2. Those who exercise or want to control weight

People doing cardio (running, cycling) or wanting to build some muscle.

• Calculation: Body weight (kg) x 1.2 - 1.5
• Example: A 60 kg person should consume about 72-90 grams of protein daily.

3. Muscle builders

Those focusing on heavy weight training to increase muscle size.

• Calculation: Body weight (kg) x 1.6 - 2.2
• Example: A 60 kg person should consume about 96-132 grams of protein daily.

4. Older adults

Older people need more protein than working-age adults to prevent muscle wasting.

• Calculation: Body weight (kg) x 1.0 - 1.2

Caution: Excessive protein intake may harm health

Meeting protein targets benefits muscle building and weight loss, buttoo much of anything can be harmful.Especially if consumed excessively over time or incorrectly. Excess protein forces the kidneys to work harder to eliminate waste and may lead to fat accumulation if not fully burned.

Additionally, risks include dehydration, constipation, and bad breath from nitrogen breakdown. Therefore, protein intake should match body weight, with sufficient water and vegetables for safety.

In summary, eating the right amount of protein for your body is most important.

Appropriate protein intake is the foundation of good health. Knowing how to calculate it helps plan meals accurately without excess or deficiency. It is crucial to distribute protein evenly throughout the day rather than in a single large meal for optimal absorption.
