The total minimum weekly exercise duration recommended for effective weight management is 300 minutes. This guideline is supported by a substantial body of research that indicates higher levels of physical activity contribute more significantly to the prevention of weight gain and the maintenance of weight loss. Engaging in 300 minutes of moderate-intensity aerobic activity each week can help create the calorie deficit necessary for weight loss and long-term weight management by promoting increased energy expenditure.

Additionally, studies have shown that while lower durations of exercise, such as 150 minutes, can be beneficial for overall health and can assist in weight loss, they may not be sufficient for those who are looking to manage their weight more effectively, especially after significant weight loss. Thus, aiming for 300 minutes allows for more flexibility in incorporating different types of activities, which can enhance overall fitness and prevent plateaus in weight loss efforts.
