there are 3500 calories in a pound. to lose 5 pounds you would need to reduce your weekly caloric intake by 3500x5=17500 calories (check my math there, i did it in my head.) so if you re eating 2000 calories a day, according to my math, you couldn t lose 5 pounds in a week because you re only eating 14000 calories a week anyway. you d have to not eat at all, and exercise.
About 2,700 a day! You should burn 300 more calories then you intake a day to lose 2 Ibs. a week, so you would have to do an extra 700. If you want to lose weight, the maximum calories you are eating a day should be 1,600! Preferably 1200-1500 or 1300-1600 if you are a guy. It would be really difficult to burn nearly 3,000 a day unless you are really active.
3500 calories = 1 pound.IF you were to burn 500 calories per day, every day for a week, then you would lose only one pound. So, to lose 5, you need to burn 2500 per day. That s a tremendous amount of energy you d have to exert in combination of cutting back on the diet.
well you can t eat 2000 calories a day AND burn 3000 calories a day. i would shoot for 500 calories a day, thats a good cardio workout.and if you start to get hungry, eat small snacks high in protein.
3000 calories= one pound
it would be very difficult to lose that much weight while eating 2000 calories a day. try 1400 instead.
