I'm not sure how much I should be eating to lose weight.

I'm a 21yr old male weight 155 lbs, 5 feet 8 inches and I'm trying to lose some weight I'm eating around 1500 cal a day but in some websites it says that I should be eating 2000, I have a sedementary life. Can someone tell me If I'm eating enough or should I be eating more.

People have different calorie needs based on their age, height and activity levels. The first thing you need to understand to lose weight is BMR or Basal Metabolic Rate. According to the BMR calculator, you need 1750 calories to maintain your weight. By eating 1500 calories a day (deficit of 250), you can expect to lose about half a pound a week. To lose one pound a week, you need a deficit of 350 calories, whether it be from lesser food intake or burning more from exercise. Hope this helps! Good luck.

BMR is what you'd burn in a comma and you probably aren't that sedantry! and you need a daily deficit of 500 to loose a pound a week. It isn't recommended that men eat any less than 1500 calories though. Putting your stats into phord (one of the more trusted calculators) your burning 2022 calories a day and should eat 1685 for healthy weight-loss.

Your Estimated BMR (calculated at http://phord.com/cc):
