Question 1

How much protein do I need per day?

Accepted Answer

The RDA minimum is 0.8 g/kg body weight for sedentary adults. However, active individuals need more: 1.2-1.4 g/kg for moderate exercise, 1.4-1.7 g/kg for athletes, and up to 2.2 g/kg for bodybuilders or those doing heavy resistance training.

Question 2

When should I eat protein?

Accepted Answer

Distribute protein intake evenly across meals (20-30g per meal) for optimal muscle protein synthesis. Post-workout protein (within 2 hours) is beneficial but total daily intake matters most.

Question 3

Can I eat too much protein?

Accepted Answer

For healthy individuals, high protein intake (up to 2.2 g/kg) is generally safe. However, those with kidney disease should consult a doctor before increasing protein. Very high intakes (>2.5 g/kg) offer no additional benefits.

Question 4

What are good protein sources?

Accepted Answer

Complete proteins include meat, fish, eggs, dairy, and soy. Plant proteins like beans, lentils, quinoa, nuts, and seeds are also excellent. Aim for variety to get all essential amino acids.

Question 5

Is plant protein as good as animal protein?

Accepted Answer

Both are valuable. Animal proteins are complete (contain all essential amino acids), while most plant proteins are incomplete. Combining different plant proteins throughout the day ensures you get all essential amino acids.

Question 6

Do I need protein supplements?

Accepted Answer

Most people can meet protein needs through whole foods. Supplements like whey or plant-based protein powder are convenient options for athletes or those struggling to meet targets through diet alone.

Question 7

Does protein help with weight loss?

Accepted Answer

Yes. Protein increases satiety, preserves lean muscle during calorie restriction, and has a higher thermic effect than carbs or fats. Aim for 1.2-1.6 g/kg when losing weight.

Question 8

How much protein should older adults eat?

Accepted Answer

Adults over 65 may benefit from higher protein intake (1.0-1.2 g/kg) to prevent muscle loss (sarcopenia) and maintain strength and function.
