In general, if you cut 500 to 1,000 calories a day from your typical diet, you'll lose about 1 pound (0.5 kilogram) a week. It sounds simple. However, it's more complex because when you lose weight, you usually lose a combination of fat, lean tissue and water.
How much weight can you lose on 500 calories a day for 2 weeks?
Decreasing your overall calories by 500 to 1,000 calories per day will turn into a weight loss rate of one to two pounds a week. Focus on nutrition, not calories. But you should keep in mind that nutritious, fresh foods are healthier than processed “diet” foods.
