Walking can support weight loss, but there is no single number of daily minutes that guarantees a result. Your starting activity level, walking intensity, eating pattern and consistency all affect what happens over time.
For a beginner, the practical goal is to build enough walking to matter without making week one so aggressive that the routine disappears by week two.
TL;DR: Walking can help with weight loss by increasing the amount of energy you use, but there is no single number of walking minutes that guarantees results. Adults are advised to get at least 150 minutes of moderate-intensity aerobic activity each week for general health, and weight management may require more activity depending on your eating pattern, starting point and individual response. If you're new to exercise, start with short walks and build gradually rather than trying to hit a large weekly target immediately. [1]
