📐 计算公式
Daily Protein (g) = Weight (kg) × Activity Factor (g/kg)
Activity Factor: Sedentary 0.8 / Light 1.0 / Moderate 1.2 / Intense 1.6 / Athlete 2.0💡 计算原理
- •Protein is a fundamental building block for muscles, skin, hormones, and enzymes.
- •Adults need at least 0.8g/kg of protein, increasing with exercise levels.
- •For muscle building, 1.6-2.2g/kg is recommended; for weight loss, 1.2-1.6g/kg helps preserve muscle.
- •1 gram of protein provides 4kcal of energy.
- •20-40g of protein per meal is optimal for muscle protein synthesis.
- •Leucine-rich foods (whey, eggs, chicken) are more effective for muscle building.
❓ 常见问题
Q. How much protein should I eat daily?
A. General adults need 0.8-1.0g per kg of body weight. Active individuals need 1.2-2.0g/kg. For muscle building, up to 1.6-2.2g/kg is recommended.
Q. Can eating too much protein be harmful?
A. For healthy individuals, up to 2.0g/kg is safe. However, those with kidney issues should consult a doctor. Excess intake may lead to calorie surplus.
Q. Can I eat all my protein in one meal?
A. Research shows 20-40g per meal is optimal for muscle synthesis. While more can be absorbed, distributing across meals is more efficient.
Q. When should I eat protein after exercise?
A. Within 30 minutes to 2 hours post-workout is ideal, but total daily intake matters more. Consistent intake is key over timing.
Q. How can vegetarians get enough protein?
A. Use tofu, lentils, chickpeas, quinoa, and nuts. Combining various plant proteins ensures all essential amino acids are consumed.
