text: For a more accurate estimation, you can go to menshealth.com. You can compute your calorie needs per day depending on your weight and activity level. I think the calculator is under the title "Lose a pound per week."\n\nHere's the link:\nhttp://www.menshealth.com/cda/tools.do?tid=calorie.counting\n\nSo based on your weight and activity level (I used the "no exercise" option), you need around 1980 calories per day to maintain your current weight. And less 500 calories per day for weight loss.
