Study shows that physical activity is better for health than weight loss – 06/23/2022

The number of obese people has increased significantly in recent decades. Along with this came weight loss methods, dieting and weight loss efforts.

However, according to a review article published in the magazine iScienceUsing it to treat obesity, which focuses not on weight loss but on physical activity and physical conditioning, is more effective for health.

Obesity, weight loss and physical activity

As I said, the authors believe that both obesity and weight loss efforts are on the rise around the world, however, these efforts are contributing more to the weight gain and the accordion effect, which is a major health risk and They are also associated with frustration.

As part of weight loss programs, we have physical activity exercises, which are traditionally used in these cases to reduce calorie intake, while the main benefits of physical activity for health, which are in weight. Do not depend on the reduction, are on the left. .

With that in mind, researchers Glenn A. Geiser, author The big lie: the truth about your weight and your healthAnd Siddhartha S. Angadi of the University of Virginia in the United States of America tried to understand whether weight loss should be the mainstay of obesity treatment.

They compare the effectiveness of physical activity or cardiovascular fitness (or cardiovascular fitness, which means the ability of the circulatory and respiratory systems to deliver oxygen to the muscles to produce energy during physical activity) to reduce the risk of stroke. Do it with weight loss. Mortality rate and heart disease.

To do this, he wrote a review article and concluded that physical activity exercise as part of a strategy is more effective than focusing on weight loss.

5 Reasons to Focus on Neutral Obesity Treatment

The authors of the study reached their conclusions and suggested the treatment of obesity, which is guided by weight neutrality based on the following reasons.

1- The risk of obesity-related deaths is reduced or eliminated by physical activity or the exercise of good physical condition.

Generally, it is said that high body mass index (BMI) (greater than 25 kg / m²) increases the risk of death.

However, apart from knowing the flaws in this index (such as not taking into account differences in body composition and not providing information on the distribution of body fat), the relationship between BMI and mortality is not so clear. As some studies show. Used in reviews.

While some indicate a higher risk of death for adults in the entire BMI range of more than 25 kg / m², others indicate a lower risk in those considered overweight, or BMI values. They range from 25 kg / m² to 30 kg / m². In addition, in the elderly, BMI associated with low mortality rates is generally seen in the overweight category.

In studies that included cardiovascular fitness, low physical fitness was associated with a higher risk of death, regardless of BMI. Similarly, epidemiological studies show that exercising significantly reduces the risk of BMI-related deaths or heart disease.

2- Physical activity and fitness improves cardio metabolic health regardless of weight loss.

The authors show that physical activity and fitness can contribute to an improvement in cardio metabolic markers, including heart disease, hypertension, and type 2 diabetes, as well as, but independently, weight loss.

Furthermore, he noted that reducing calories more than physical activity is more effective in reducing body fat reserves, but such a restriction is not sustainable in the long run.

3. Weight loss, even if deliberate, is not significantly associated with a lower risk of death

Although some studies suggest that deliberate weight loss through calorie restriction may reduce the risk of death, others ignore this association.

That is, deliberate weight loss does not appear to be associated with a lower risk of death.

Furthermore, the pursuit of weight loss traditionally involves a reduction in calorie intake and an increase in physical activity levels, so it is not clear whether weight loss-related mortality studies have been successful. This weight is actually the main factor of these results. .

4- Increased fitness or physical activity is associated with a greater risk of death than deliberate weight loss.

On the other hand, there is more conclusive evidence that good physical condition can reduce the risk of death.

5- The accordion effect is associated with many health problems.

Weight cycling, or accordion effect, is when a person loses weight and then regains it over and over again, in a vicious cycle. Its effects have been debated for years.

Although some studies show that there is no risk to health, others suggest that the effects of accordion cause health problems such as obesity, increased risk of death, heart disease and Adults with type 2 diabetes and arterial disease have side effects. Coronary

The study helps to understand the concept of “fat, but healthy”.

Finally, the authors make it clear that they do not want to discourage weight loss, but suggest obesity treatments that guide weight loss and lead to better health outcomes, primarily in physical activity and fitness. Focuses on improvement.

He also acknowledges the limitations of the review studies, but despite the shortcomings, believes that the evidence can help clarify the controversy surrounding the notion of “fat but healthy”, referring to those who Overweight or obese in terms of BMI, but healthy in point of view. From a cardiometabolic point of view.

This topic deserves further investigation and I hope that such studies can help reshape obesity and lead to more humane and respectful treatment.

Bon appetit!
