For many years, health professionals have emphasized the advantages of consistent physical activity for weight management. However, the question remains: how much exercise is sufficient? A recent investigation led by Dr. Ahmad Jayedi from Imperial College London and Semnan University of Medical Science examined the connection between aerobic exercise and weight loss, providing insights for individuals facing obesity and overweight challenges.

Findings of the study:

The research involved a comprehensive analysis of 116 randomized clinical trials with a total of 6,880 participants, aimed at determining the impact of aerobic exercise on body weight, waist circumference, and body fat. The findings indicated that engaging in 30 minutes of aerobic exercise each week could result in an approximate weight loss of 1.15 pounds, a reduction in waist circumference of 0.56 cm, and a decrease in body fat percentage by 0.37%.

The study further suggested that 150 minutes of moderate-intensity aerobic exercise weekly could lead to significant reductions in waist circumference and body fat, with an average weight loss of 6.15 pounds. Notably, when participants increased their exercise duration to 300 minutes per week, the average weight loss rose to 9.24 pounds, accompanied by proportional decreases in waist size and body fat.

Many benefits of exercise:

Weight loss is a primary benefit associated with regular physical activity, but its positive effects extend beyond this. The study noted enhancements in both mental and physical well-being, as well as overall quality of life among participants who exercised regularly. Vigorous exercise proved to be more effective for weight loss compared to moderate-intensity aerobic activities. Additionally, reductions in visceral fat and changes in body composition occurred more rapidly with vigorous exercise, particularly when performed for longer durations each week. However, some participants reported minor issues, such as musculoskeletal discomfort in the knees and ankles, following vigorous workouts.
