That's almost impossible to answer without sufficient information. I can tell you how much calories you shouldn't be eating. I have read on a website that eating 3500 calories less per week will take off one pound. So that means eating 500 less calories each day of the week, which is very easy to do once you learn what foods you should be eating and what foods aren't so nice. It is also a good idea to burn off 250 calories with exercise everyday and get rid of the other 250 daily by eating right.
One pound is 3500 calories. 3500 x 25 = 87500 calories
It is simply not possible to lose 25 pounds per day.
To lose 25 pounds in five weeks, one should lose five pounds a week. This is equivalent to losing 0.71 pounds a day.
No, you cannot lose 25 pounds in one night. Unless you get liposuction or surgery at night and removed 25 pounds of your body.
1 pound of fat = 3,500 calories. So 25 pounds of fat is 87,500 calories. Remember, start slowly, keep EXERCISING, and don't go below the 2,000 calories per day mark (or starve yourself).
The number of miles a person must run to lose 35 pounds in 5 weeks depends a lot on the size of the person and the speed at which you run. Running at the fairly moderate pace of 5 MPH, a person who weighs 165 pounds will burn about 126 calories. You need to burn 3500 calories to lose one pound. This means that you'd need to run almost 28 miles in 5 weeks to lose one pound, and 35 times that, or about 972 miles, to lose 25 pounds. However, running will increase your overall metabolism so you won't actually need this many miles, and if you cut some calories out of your diet you will lose weight faster.
A pound of fat has 3500 calories. Most men require 2500 calories a day. So if you eat 1500 a day instead that's a 1000 kcal deficit. 1000 x 7 = 7000 deficit per week (7000/3500 = 2). You'll lose around 2 pounds of fat a week. At this rate it would take 25 weeks to lose 50 pounds (5 and half months). You'll loose it faster if you burn off extra calories through exercise.
25.
it is 25 calories
There are many factors involved. First of all, are you 25 pounds overweight? If you aren't, it would be dangerous to loose that much. If you work a safe diet and exercise plan, you should be able to lose 25 pounds in about six months. That is a rate of 1 pound every week. You are likely to lose more the first couple of weeks.
The average person burns about 100 calories per 1 mile they run. To lose one pound, you need to burn 3,500 more calories than you consume, which would also be 17,500 calories burnt to lose five pounds. This would take about 175 miles. Over a 7-day week, that is roughly 25 miles a day.
