Be careful of doing such an extreme workout. Burning 900 calories a day is very healthy but your intake should be about/over 1500 calories a day.
The risks are that you might lose a lot of weight really fast and as soon as you eat some chocolate or you simply go over your low calorie daily intake you'll put all the weight back in no time.
ok to lose weight u need to burn more calories then you are consuming.. if you eat 1200 calories and only burn 100 then your total for that day is still +1100 . see what i mean? so you must burn an amount greater then 1200 calories in order to lose weight.. i dotn know how to measure calories burned but i would guess about 2 hours exercise a day would be enough
If you are eating 1500 calories a day you will lose 1 lb. if you are eating 1200 calories you will lose 1.6 lbs.
The ONLY way someone can lose weight is to burn more calories than you consume in one day...the average female eats 1200-1400 calories a day and sitting in the office or just standing up will burn calories but not as many as when you are active , exercising burn 5x the calories than doing nothing at all. so the more calories burnt the less weight.
depending on your weight you will burn more or less calories, but a male weighing about 150pounds should burn around 600-800 calories.
You have to jog or run for a long time to burn that much.
eating the same amount of calories that you burn in a day will make your weight stay the same, to lose weight burn more calories then you eat and to gain weight eat more calories then you burn
Yes the longer and harder you play the more calories you'll burn. You burn about 15 calories an hour just sitting, so if your running around a court swatting a ball you probably burn somewhere around 600 calories an hour plus it builds up your metabolism which means you'll burn more calories sitting or sleeping. So YES you will lose weight playing tennis.
if you do that, you will die. your body needs aleast 1200 calories a day in order to keep your matabolism up. if you eat less then that your matabolism will slow down and you will gain weight. there are tons of websites that you can enter your weight and your goal weight into and it will tell you how many calories you should eat a day and how many you should try to lose.
You will not lose weight (body fat) if consume as many calories as you burn. You will also not gain any body fat.If you eat 2000 calories a day, and go to the gym and burn 2000 calories doing various exercises, you WILL lose weight. This is because your body constantly burns calories to keep you alive. You burn then when you walk around, when you sit on the couch, when you sleep, even when you chew more food and digest. But if the sum of your workout calorie burn, and you daily natural calorie burn adds up to 2000 calories, and that's what you consumed that day, your weight will remain constant.
Caloric needs are based on activity levels, I would suggest 1200 calories per day and increase your exercise to burn off excess weight.
somewhere between 700 and 1200 calories depends on weights you use and how into it you are as well as if you try to take break in between when your not supposed to
It all depends on you body and how much exericse you are doing. If you consume that many calories (which, for the average person, is considered "dieting"), you need to exercsie to burn off calories to lose weight.
