This question is about Running
Running fast or slow can lead to weight loss. Both moderate-intensity exercise and high-intensity exercise have been shown to lead to weight loss and running intensity should be individualized based on fitness level, age, weight loss goals, training frequency and other factors [ 1
Research suggests that 150-250 minutes of moderate-intensity physical activity each week will provide modest weight loss, while greater amounts (>250 minutes/week) have been associated with clinically significant weight loss [ 2 1
In conclusion, the more consistent you are with running (and the more your speed and distance improve) the more likely it is for you to lose weight [ 3
