What Does It Take to Lose 1 kg of Weight?

To lose 1 kg of body weight, it’s generally estimated that you need to create a calorie deficit of around 7700 calories. The reason behind this is that approximately 7,700 calories are stored in each kilogram of body fat. In simple terms, you need to either burn 7700 calories more than you consume, or reduce your calorie intake while maintaining your energy expenditure.

How Many Calories to Burn to Lose 1 kg per Week?

To lose 1 kg in a week, you would need to create a daily calorie deficit of about 1000 calories. This can be achieved by a combination of dietary changes and increased physical activity. It’s crucial to note that a safe and sustainable weight loss plan should aim for a gradual reduction in weight, about 0.5 to 1 kg per week. Rapid weight loss may not be sustainable and can sometimes lead to health risks.

Depending on your baseline calorie needs, reducing your daily calorie intake by 500 to 1000 calories will help you achieve weight loss. For example, if your daily maintenance calories are 2500, cutting down to 1500-2000 calories per day would create the required deficit.

However, it’s essential to never drop below the minimum recommended intake (1200 calories per day for women, 1500 calories for men) unless under medical supervision. A balanced diet is key to maintaining your health during the process.

While it’s theoretically possible to lose 1 kg in a day through extreme measures like excessive calorie restriction or excessive exercise, this is not recommended. It is unsafe and unsustainable.

Sustainable weight loss is the healthiest approach to achieving long-term success.

How to Calculate Your Calorie Deficit to Lose 1 kg?

To calculate the calorie deficit required for losing 1 kg, you need to consider your current weight, activity level, and metabolic rate. For example, if your daily calorie expenditure is 2200 calories, and you reduce your intake by 500-1000 calories, you’ll be in a calorie deficit and can start working towards your weight loss goal. It’s essential to track your progress regularly with tools like the Weight Tracker to ensure that you’re on the right path.

How Many Calories Should You Eat to Lose 1 kg in a Week?

For most people, aiming to consume 500-1000 calories less than their maintenance level per day can lead to a weight loss of about 1 kg per week. However, it’s vital to maintain a balanced diet rich in nutrients, ensuring that you’re still meeting your body’s needs for vitamins, minerals, and other essential nutrients.
