Answer:
The success (attain and maintain reduced weight for 3 to 5 years) of non-surgical weight reduction programs has been reported to be approximately 5% for adults
Step-by-step explanation:
The prevention of unwanted weight gain from excess body fat is the most essential component of an effective weight-management program. The basic principle of weight gain is that energy intake is greater than energy expenditure. This occurs when the diet contains more energy than is expended. Therefore, the excess energy is stored as adipose fat tissue.
Energy expenditure by the body daily, is mainly due to the basal metabolic rate, thermal effect of food, and effects of physical activity. Of these three main processes of energy expenditure, the greatest portion of energy expenditure by most adult humans is for basal metabolism. This is the energy spent in maintaining all involuntary processes in the body such cellular activity, respiration, and circulation at rest, awake, and in a non-absorptive state.
An effective program for weight loss would include control of total energy intake, increased physical activity, modification of food habits and lifestyle change strategies. Surgical weight-reduction has proven to be more successful than non-surgical methods for people who are severely obese. The success or failure of a weight-reduction program is measured by the maintenance of weight loss over a period of between 3 to 5 years and above. If weight loss is maintained over this period, it considered successful, if not, the program is considered to have failed.
The success (attain and maintain reduced weight for 3 to 5 years) of non-surgical weight reduction programs has been reported to be approximately 5% for adults.
