Body Weight Loss And The Importance Of Metabolic Function

Successful body weight loss is dependent on the body’s level of metabolic function. In every day life, a healthy diet delivers thousands of calories from foods, and an active body uses most of them to function. Some people, however, eat too much or exercise too little. A person who has consumed more food energy than he or she has burned in caloric intake, will keep the excess calories in body fat.

To reduce body fat, or experience body weight loss, a person needs to expend more energy than the amount taken in as food. Healthy eating is a requirement in the process of raising metabolism levels and in maintaining a high level of operation.

Metabolic Function

Because Metabolic Function is so important for body weight loss, a person should have a clear understanding of the overall process.

Metabolic function, or metabolism, is the total sum of all the chemical reactions that go on in living cells. Energy metabolism includes all the reactions by which the body obtains and uses energy from food. If energy intake exceeds the body’s energy requirements, the result will be weight gain. This is why metabolic function of the body is essential for body weight loss.

Many fad diets emphasize fasting or low calorie intake. Metabolism slows during this process in an effort to conserve body tissues. The body begins to reduce the energy output to conserve fat and lien tissue. The lien tissues (muscles) shrink in mass and perform less metabolic work. The metabolic function is at a low, and weight loss slows due to the metabolic function factor.

Raising Metabolism Levels

In order for a person to establish an approximate food or energy intake level, he or she must eat a set number of calories per day. For example, if a person desires to eat 2000 calories a day and not gain weight, the metabolism level needs to be set for 2000 calories per day. This is done by eating 2000 calories per day for a given period of time. The time period will vary per individual depending on body structure and body weight. Some people may reach the desired calorie level in two to four weeks, while others may take as long as one to two months.

Body Weight Loss

Once the metabolism level is set for the 2000 calorie per day diet, or the desired calorie goal level, the individual can maintain a set body weight with proper nutrition and exercise or begin to experience body weight loss. This is done by lowering the calorie intake for a given period of time while exercising and following a healthy weight management plan.

The higher the metabolic rate and the higher the energy output of physical activity, the higher the metabolism will be. An individual burns close to 75% of calorie intake on a daily basis. Physical activity and healthy eating will increase daily calorie expenditure.           

As a result, body weight loss will take place as it is dependent on the metabolic function.
