Cardio exercise will also increase the amount of calories your body uses during and immediately after exercise. Choose some kind of mild cardio exercise that you dislike the least and do it six days a week. Brisk walking is a good way to start. Walking for weight loss is very effective when done properly and it is sustainable long term. 'Brisk' means walking at a 4 mph pace. Slowly work up to that pace and then slowly increase your distance. If you want to use that form of mild cardio to lose body fat, you will need to average walking from 3 to 6 miles daily at that pace. Ideally (for maximum effect), walk before your first meal of the day. Don't worry if you are not able to do that, you can still achieve good results. You do not have to do your entire daily walking at once and you can split it up into more than one walk.
