Quick Answer: How Many Calories to Lose 1kg Per Week?
To lose 1kg per week, you need a total calorie deficit of 7,700 calories per week, which equals approximately 1,100 calories per day.
This can be achieved by:
Eating fewer calories
Increasing physical activity
Combining both for faster results
👉 This is the foundation of every daily calorie deficit to lose 1kg per week plan.
What Does “Calories to Lose 1kg Per Week” Actually Mean?
When people search for calories to lose 1kg per week, they’re really asking one core question:“ How do I create a calorie deficit that guarantees fat loss?”
Your body stores excess energy as fat. When you create a calorie deficit, your body uses that stored fat for fuel.
This process is known as:
fat loss through calorie deficit
energy balance weight loss
calories in vs calories out
Understanding this concept is critical because it applies to every variation of weight loss, including:
calories to lose 1kg per week female
calories to lose 1kg per week male
calorie deficit for beginners weight loss
The Science: Why 7,700 Calories = 1kg Fat Loss
The 7700 calorie rule is based on the energy stored in body fat.
1 gram of fat ≈ 9 calories
1kg of body fat ≈ 7,700 calories
This is why searches like:
how many calories equal 1kg fat
calories needed to burn 1kg fat
weekly calorie deficit for 1kg weight loss
all lead to the same conclusion.
However, real-world fat loss can vary slightly due to:
metabolism
water retention
hormonal changes
Still, this formula remains the most reliable guideline.
How to Calculate Your Daily Calories to Lose 1kg Per Week
To apply this correctly, you need to calculate your TDEE (Total Daily Energy Expenditure).
Step 1: Find Maintenance Calories
This is how many calories your body needs daily.
Step 2: Subtract 1,000–1,100 Calories
This creates your calorie deficit for 1kg fat loss per week
Example
If your maintenance calories are 2,400:
Target intake: ~1,300 calories
Daily deficit: ~1,100 calories
Result: ~1kg fat loss per week
