How to Lose Weight with Calorie Counting

Weight loss ultimately comes down to one principle: consuming fewer calories than you burn. This is called a calorie deficit. Let's understand how to do this effectively and sustainably.

Understanding Calorie Deficit

Your body burns calories in three ways:

  • BMR (Basal Metabolic Rate): Calories burned at rest (~60-70%)
  • Physical Activity: Exercise and daily movement (~20-30%)
  • TEF (Thermic Effect of Food): Digesting food (~10%)

Calculate Your TDEE

TDEE (Total Daily Energy Expenditure) is how many calories you burn daily. A simple formula:

  • Sedentary: BMR × 1.2
  • Light Activity: BMR × 1.375
  • Moderate Activity: BMR × 1.55
  • Very Active: BMR × 1.725

Setting Your Deficit

  • Mild (250 cal/day): Lose ~0.25 kg/week
  • Moderate (500 cal/day): Lose ~0.5 kg/week
  • Aggressive (750 cal/day): Lose ~0.75 kg/week

Tips for Success

  1. Track everything you eat - even small bites count
  2. Weigh food when possible for accuracy
  3. Don't drink your calories (avoid sugary drinks)
  4. Prioritize protein to preserve muscle
  5. Be patient - sustainable loss is 0.5-1 kg per week

Remember: Consistency beats perfection. It's better to maintain a smaller deficit long-term than crash diet and give up.
