Many people want to know. How many calories to lose weight?
Calories are the measure of energy in food. Scientifically speaking, one calorie is the amount of energy needed to raise the temperature of one gram of water by one degree centigrade. People need the calories derived from food to function. The body uses sixty to sixty five percent of the calories people consume to perform such bodily functions as breathing, digesting, purifying blood, heart beating and maintaining body temperature. It uses another ten percent to process the food consumed. Although the calorie-needs of individuals vary considerably depending on factors such as gender, body frame and the person’s activity level; people need approximately 1,200 calories simply to live. A calorie intake lower than 1,200 can decrease iron levels in the body and can lower the person’s metabolism. Still want to know how many calories to lose weight?
To determine how many calories to lose weight, first you should determine the amount of calories you need to maintain yourself at the present time. These basic calorie needs of people vary substantially depending on many things, including the person’s gender, body frame, age, activity level, current weight and height, and even the current climate when looking at how many calories to lose weight.
Smaller people and those living in warm climates need fewer calories to lose weight than larger persons or those living in cold climates. Also, younger persons need more calories than older people. Men need about five to ten percent more calories than women, however, pregnant and lactating women need about 300 to 500 more calories a day than what they usually consume when figuring up how many calories to lose weight.
Physical activity is another factor that determines the calorie needs of individuals. A person who leads a highly active lifestyle needs more calories than a person who leads a sedentary lifestyle. With all that said, how does a person know how many calories to lose weight and the exact amount of calories they should stick to in order to, safely and effectively, lose weight?
A doctor can provide advice on the best number of calories one should adhere to for losing weight and maintaining weight. However, knowing something about the calories found in different foods and how they work in the body, will help one in achieving how many calories to lose weight. Each food provides different amounts of calories. Carbohydrates and proteins contain about four calories for each gram of their weight. One gram of dietary fat contains about nine calories, and one gram of alcohol contains seven. This small example shows that alcohol and food containing fat has more calories, and a dieter should avoid them while dieting and even after dieting in order to maintain their weight.
However, dieting does not mean that one need only consume low-calorie food. A diet should be nutritious as a healthy diet plan will help one to lose weight in many ways. The foremost way a dieter accomplishes weight loss is through the person’s metabolism.
Metabolism refers to how each person’s body processes and uses the food they eat, and each person’s metabolism is unique. There are many vitamins and minerals needed to maintain the metabolism of the person, and a proper metabolism becomes jeopardized if the body is lacking in any of these vitamins and minerals. This, in turn, will affect weight loss negatively and could affect how many calories to lose weight. Secondly, poor nutrition will create digestive problems. The food one consumes will not be digested or assimilated properly as the digestive system needs vitamins and minerals. It also needs dietary fiber as dietary fiber aids in such things as cleaning up the gastrointestinal tract and prevents constipation and indigestion. Knowing the different food and their categories will help dieters immensely in losing weight.
The first category is empty-calorie food. Empty-calorie food is the worst food from the nutritional and calorie point-of-view. These food and drinks have many calories but little or no nutrients. They also offer no vitamins or minerals. Dieters should avoid food in this group such as candy, cookies, soda and energy drinks.
The next group is calorie-dense food. This category includes food that is high in fat calories and food that is high in fat and sugar. This includes food such as sausages, butter, mayonnaise and some other processed food. Food in this group is not recommended for weight loss.
The next group is negative-calorie food. Food in this group burns more calories during their processing than what they contain. This gives food in this category a natural fat burning ability and are excellent for weight loss. Most fruits and vegetables can be found in this group.
The last group of food is fat-burning food. This food is perfect for dieting too as it helps the body burn up fat. Food in this category includes olives, green tea, ice-cold water, spinach, eggs, beans and some fish.
In conclusion, the calorie needs of each person varies widely depending on many factors such as gender, age, body frame and activity level. Learning about how the metabolism works, and learning about the different groups of food and how they interact with the body will help an immense deal in one’s weight loss program. No weight loss plan would be complete without proper exercise, as well. Regular exercise will not only help burn calories and lose weight, but it will also improve one’s overall health. A doctor can help one in determining how many calories to lose weight and help to implement a diet plan, and a suitable exercise program one can handle.
