How many cals. to lose 10 lbs in 10 days?

Answer 1

For you to lose 10 pounds in 10 days... really it will mostly be water weight. But aiming to lose 10 pounds of FAT in 10 days (a pound a day) requires you to burn an excess of 3500 calories each day.

To start, take your weight in pounds and multiply by 10 and that's how many calories you use to maintain your body on an average day with a weak metabolism (which you will have after starving for a week). Example: 150lbs X 10=1500 calories.

Now if you eat nothing, you will burn 1500 calories a day.

To reach the 3500 calorie deficit you need, you now need to workout to burn 2000 more calories.

Or.. you could each 1000 calories, and work off 3000. How ever you want to mix and match eating and workout to get -3500 for the day.

My suggestion is though to drink a lot.. a LOT of water. 64oz at least. And that will help flush your water weight too.

I mean, if you actually manage to burn 3500 calories in a day for 10 days AND keep up the water intake, you will likely lose more than just 10 pounds. But you might also get very sick. Your body isn't built to handle burning 2000 calories in a workout when its not eating any. And unless you're insanely obese, going past a 1000 calorie deficit is unhealthy.

Just ask yourself if these 10 pounds are worth your life. Good luck.
