Physical activity can reduce poor health consequences of obesity. Guidelines for obesity management should focus on weight loss through increased physical activity not dieting.
Studies have shown that repeated weight loss is associated with adverse health outcomes.
A recent study revealed that increased exercise and improvements in fitness levels will help you avoid obesity-related health risks and mortality.
The Centers for Disease Control and Prevention (CDC) states that 42.4% of American adults were obese in 2017–2018, a marked increase from 30.5% in 1999–2000.
Now, a recent review examines how to reduce the risk of obesity-related health conditions and premature death. It compares the effectiveness of physical activity and cardiorespiratory fitness with that of weight loss. Cardiorespiratory fitness is defined as a component of physiologic fitness that relates to the ability of the circulatory and respiratory systems to supply.
The study results are featured in the journal iScience.
The overall study found that improvements in cardiorespiratory fitness and physical activity tend to reduce the risk of cardiovascular disease and mortality due to obesity.
“Unhealthy weight loss practices are much more common among persons with a high BMI who also attempt weight loss more frequently. We contend that it is entirely plausible that [many] of the health risks associated with obesity are due to the adverse effects of weight cycling. Weight cycling is associated with increased mortality risk, and weight cycling is more prevalent among persons with obesity,” the article’s co-author, Dr. Glenn Gaesser said.
