Yes, 7-8 km of daily walking can help you lose weight, especially if you combine it with a healthy diet.
A low-impact aerobic exercise like walking can boost your metabolism and enable you to burn more calories.
The number of calories you burn when walking depends on a number of factors, including weight, pace, and the surface you're walking on.
However, it's important to remember that how many calories you consume and burn ultimately determines how much weight you lose.
Even if you walk frequently, you could not lose much weight if you're taking in more calories than you're expelling.
Consistent exercise and a wholesome diet must be combined in order to achieve weight loss objectives.
