Introduction To Weight Loss

Whether you are trying to lose five pounds or over 50, the same laws of physics simply determine whether or not you will lose weight and the speed of your weight loss will happen. Remember these simple instructions and putting them into practice can lead to weight loss, without the aid of special diet plans, books or medicines.

Our weight is determined by the amount of energy that we have in food, and the amount of energy spent on the activities of our day. The energy is measured in calories. If the weight is constant, probably taking the same amount of calories burned each day. If you are gaining weight slowly over time, it is likely that their caloric intake is greater than the number of calories you burn through their daily activities.

Everyone is in controlling the amount of food he or she consumes each day, so that the caloric intake is something that we can control. For further extent, we can control our production of energy, or the number of calories burned each day. The number of calories burned each day depends on:

* Our basal metabolic rate (BMR), the number of calories burned per hour, simply by being alive and the maintenance of bodily functions,
* In addition to our level of physical activity.

For some people, because of the genetic (hereditary) or other factors, the resting metabolic rate may be slightly higher or lower than average. Our weight also plays a role in determining the amount of calories burned at rest - we need more calories to maintain their body in its current state, the highest weight of his body. A 100 lb person requires less energy (food) to maintain their body weight for a person who weighs 200 pounds.

Lifestyle and work habits in part to determine the number of calories you need each day. Someone whose job is to work heavy physical naturally burning more calories in a day than someone who sits at a desk most of the day (a sedentary). For people who do not have jobs that require intense physical activity, exercise or increased physical activity can increase the number of calories burned.

As a rough estimate, an average of 31-50 year-old woman who leads a sedentary lifestyle needs about 1800 calories a day to maintain a normal weight. A man of the same age need about 2200 calories. Participation in a moderate level of physical activity (exercise 3-5 days per week), requires about 200 extra calories per day.
