Physical workout enhances the rate of weight loss more than a diet; says a new study from the University of Colorado Anschutz Health and Wellness Center (AHWC) at the CU Anschutz Medical Campus.

Exercise Helps in Weight Loss
Questions such as why many struggles to lose weight over a long time was addressed in this article. The study proved that those who were able to maintain their weight engage in physical exercise and not reducing their energy intake. This further makes clearer the close link between exercise and weight loss. According to Danielle Ostendorf, Ph.D., a postdoctoral fellow at the CU Anschutz Health and Wellness Center.
The study revealed the secret behind successful weight loss as exercise or physical activity rather than dietary intake restrictions. These group of individuals described as “successful weight loss maintainers”, maintain reduced body weight through regular exercise. They lose at least 30 pounds and maintain it for a longer time such as one year or more.
Below are some of the major finding:
Weight loss maintainers consume and burn more calories each day about 300 Kcal per day more than those with moderate body weight control. And for individuals who are overweight, there is no significant difference recorded.
It was noted that a greater number of calories burned such as 180 Kcal/ day are burnt through physical exercise. Compared with individuals with normal body weight and those that are obsessed, it is a higher number. weight-loss maintainers burn much energy through physical activity more than individuals who are overweight no matter the amount of energy spent while carrying around the large body mass.
Evidently, weight-loss maintainers count a greater number of steps on a daily basis like 12,000 steps demonstrated every day. Individuals with moderate body weight count at least 9,000 steps while those who are overweight demonstrate about 6,500 steps per day.
From the findings, it was concluded that weight-loss maintainers consume the same quantity of calories as individuals who are overweight and those with moderate body weight. However, they avoid weight regain by involving in a physical workout; Victoria A. Catenacci, MD, a weight management physician and researcher at CU Anschutz Medical Campus said.
Successful weight-loss maintainers are compared to normal body size and overweight individuals. The Obsessed individuals have a body weight of about 213 pounds while the successful weight-loss maintainers recorded a body weight of about 150 pounds.
This study used the gold standard doubly labeled water method to measure the total energy expenditure in individuals with reduced body weight. Researchers were able to record each individual’s energy expenditure through urine samples between one to two weeks duration. These individuals were given a dose of doubly labeled within this period. A doubly labeled water is a form of water which its oxygen and hydrogen have been replaced with uncommon isotopes of this element solely for tracing purposes.
Measuring the daily energy expenditure from doubly labeled water also gives an accurate estimate of energy intake in individuals with normal weight. Previous studies made use of a questionnaire or diet diaries for data recording but all these have limitations and can never be accurate.
Resting metabolic rate was also measured on each individual to record the total energy expenditure at rest and that expended during a physical workout. Studies conducted in the past used individual reports or activity monitor in measuring physical activity. These techniques do not provide an accurate result.
Generally, physical activity is linked to weight loss. The above findings are consistent and accurate.
