Calories are basic units of energy that come from the proteins, carbohydrates and fats present in your body. Burning or metabolizing these substances produces energy that helps the body function. So, while exercise to burn calories is an effective way to control your weight and lead a healthy life, there are limitations on the daily number of calories you should burn. Getting rid of 1,000 calories a day is safe and healthy, as long as you consume enough calories to maintain basic bodily functions. If you burn 1,000 calories per day and do not eat enough, your body can not sustain itself. As always, consult your doctor before starting any diet or exercise program.
Basal metabolic rate
Each day your body burns a large amount of calories just to maintain its basic bodily functions such as breathing, circulation and immune function. This basic metabolic function is your basal metabolic rate or BMR (for its acronym in English). Most adults burn at least 1,000 calories per day, only through their BMR, which accounts for 60 to 75 percent of the total daily calorie burn. Walking, talking, working and other normal bodily functions add to your total calorie burn, with more than 1,000 per day.
Exercise
While your body easily burns more than 1,000 calories per day on your own, it is possible to burn an additional 1,000 calories through rigorous exercise. Many professional athletes burn 1,000 calories per day through multiple daily training and training regimens. Done in the right way, burning an extra 1,000 calories a day can be safe and healthy. However, participation in this type of intense activity for several days in a row can stress your body and should only be done under the supervision and guidance of a trained professional.
Minimum intake
While you can burn an additional 1,000 calories through exercise, you may be hungrier and consume more food, thus avoiding the burning of calories. To maintain your current weight, you must consume a greater amount of the calories you burn. Eating fewer calories than you burn can contribute to healthy weight loss, but there are limitations. Health experts recommend that men consume at least 1,500 calories per day, and encourage women to consume at least 1,200 calories per day. Because these caloric minimums do not account for excess exercise, men and women who burn an extra 1,000 calories daily should increase their minimum intake accordingly.
Considerations
There are 3,500 calories in a pound of fat. If you eat 1,000 fewer calories than you burn per day, you will lose two pounds of fat per week. Although it is considered a healthy weight loss rate, it is in the upper limit. If your goal is to lose weight, carefully control the relationship between calories burned and calories consumed. On the other hand, if weight-loss exercise is combined with a limited diet, make sure that the calories you eat contain a balance of nutrition that includes protein, dairy, fruits, vegetables and whole grains.
