Question: how many calories needed to lose 2 pounds per week?
Answer: 10 Ways to Lose 2 Pounds a Week. To lose one pound per week, you need to reach a total calorie deficit of about 3500 calories per week or 500 calories per day. To lose two pounds per week, you need to double that number. So you need to reach a 1000-calorie per day deficit or 7000 calories per week.
