What is "Daily Calories"?

Daily calorie targets should be based on maintenance first, then adjusted for fat loss or muscle gain.

Example: A calorie target fails more often from being unrealistic than from being mathematically off by a small amount.

什么是米夫林-圣焦尔方程？

米夫林-圣焦尔方程于1990年开发，目前被认为是计算基础代谢率（BMR）最准确的公式。它得到美国营养协会的推荐。

计算公式

👨 男性：BMR = 10×体重（公斤）+ 6.25×身高（厘米）- 5×年龄 + 5

👩 女性：BMR = 10×体重（公斤）+ 6.25×身高（厘米）- 5×年龄 - 161

什么是TDEE？

TDEE（每日总能量消耗）是您每天消耗的总卡路里数。它通过将BMR乘以活动系数来计算。

Activity Multipliers

Activity LevelMultiplierDescription
久坐（很少或不运动）1.2Desk job, no exercise
轻度活动（每周运动1-3天）1.375Light exercise 1-3 days/week
中度活动（每周运动3-5天）1.55Moderate exercise 3-5 days/week
活跃（每周运动6-7天）1.725Hard exercise 6-7 days/week
非常活跃（每天剧烈运动或体力工作）1.9Very hard exercise or physical job

健康饮食建议

  • ✓避免极端卡路里限制（保持至少80%的TDEE）
  • ✓摄入足够的蛋白质（每公斤体重1.6-2.2克）
  • ✓保持充足水分（每天至少2升水）
  • ✓食用富含纤维的食物

Scenario 1

Run a realistic baseline first

Result

See the first decision threshold quickly

A rough baseline is better than guessing.

Scenario 2

Change one major variable

Result

Watch how decision quality changes

Structure often matters more than the headline number.

Scenario 3

Use a more conservative assumption

Result

Stress-test the plan before committing

Conservative assumptions usually create better real-world plans.

Decision rule

Cash flow and sustainability usually matter more than optics.

How much is really affordable?

Best for

When approved amount and healthy amount are not the same

Watch for

Maximum eligibility is rarely the same as safe capacity.

When timing or conditions change the answer

Watch for

Delay can become more expensive than expected.

Decision rule

Prepared structure and consistency usually beat perfect timing.

Expert Tip

Long-term diet success usually comes from starting with a modest deficit, not the lowest number you can tolerate. When progress stalls, adjust activity and tracking accuracy before slashing calories again.

常见问题

What should I look at first in this calculator?

Start with the assumption that changes the result most. This tool is most useful for setting a decision baseline, not pretending the first number is perfect.

What is the difference between BMR and TDEE?

BMR (Basal Metabolic Rate) is the minimum calories your body burns at rest. TDEE (Total Daily Energy Expenditure) is your total daily calorie burn including BMR plus daily activities and exercise.

What is the Mifflin-St Jeor equation?

The Mifflin-St Jeor equation, developed in 1990, is currently considered the most accurate formula for calculating BMR. It is recommended by the American Dietetic Association.

📌 Key Takeaways

  • 📌Calorie goals should usually be based on TDEE, not BMR
  • ⚖️A 300-500 calorie deficit is often easier to sustain than a crash diet
  • 🏃If activity changes, old calorie targets can become inaccurate fast
  • 🥗Calories work better when paired with protein and sustainable meal structure

📊 The Science Behind Calorie Calculation

What is BMR (Basal Metabolic Rate)?

Basal Metabolic Rate (BMR) is the minimum number of calories your body needs at complete rest for basic life functions like breathing, temperature regulation, and cell activity. Simply put, it's the energy you burn in 24 hours while doing nothing. This calculator uses the Mifflin-St Jeor equation, currently recognized as the most accurate BMR calculation method.

What is TDEE (Total Daily Energy Expenditure)?

TDEE is your total daily calorie expenditure, combining BMR with daily activities and exercise. It's calculated by multiplying BMR by an activity factor based on your lifestyle. Knowing your TDEE helps you set accurate calorie goals for weight loss (eat less than TDEE), maintenance (eat TDEE), or weight gain (eat more than TDEE).

💡 Activity Factor Guide

  • • Sedentary (1.2): Office work, little exercise
  • • Light (1.375): Light exercise 1-3 days/week
  • • Moderate (1.55): Moderate exercise 3-5 days/week
  • • Active (1.725): Hard exercise 6-7 days/week
  • • Very Active (1.9): Physical job or training twice daily
