Regular Exercise ‘Critical’ of Any Attempt to Lose Weight: Study
The American Heart Association says 150 minutes of weekly moderate exercise can improve blood pressure, cholesterol and insulin sensitivity even without major weight loss.
The American Heart Association released a new scientific statement emphasizing that physical activity improves cardiovascular health in people with obesity, regardless of whether they achieve significant weight loss.
Obesity now affects more than 40% of Americans, yet fewer than 15% of people achieve a "clinically significant" amount of weight loss through exercise alone, highlighting the gap between need and outcome.
The AHA recommends a minimum of 150 minutes of moderate-intensity aerobic activity per week, though meaningful weight loss typically requires higher levels between 225 and 420 minutes weekly.
Dr. Stacey Rosen, volunteer president of the AHA, noted many people face barriers like time constraints. "Addressing these barriers can help support healthier habits over time," Rosen said.
Damon Swift, chair of the AHA writing group, stated obesity treatment requires a comprehensive, individually tailored approach. "Treatment of obesity should be individually tailored," Swift said, to sustain long-term health improvements.
