Energy balance
A daily caloric deficit of 500-1,000 kcal (low-calorie diet) produces a weight loss of 0.5-1.0 kg per week and up to 10% body weight over 6 months.
To lose weight steadily, reduce your daily calorie intake by 500 to 1,000 calories compared to what you normally eat. This moderate deficit typically results in losing 0.5 to 1.0 kg per week. Over six months, this approach can help you lose about 10% of your body weight. Focus on sustainable habits rather than extreme restriction.
