This is the only diet besides the rather extreme Cyclical Ketogenic Diet that has produced veins across my abdomen, which is the last place I lose fat . Physical activity, such as walking, is important for weight control because it helps you burn calories. If you add 30 minutes of brisk walking to your daily routine, you could burn about 150 more calories a day. Of course, the more you walk and the quicker your pace, the more calories you'll burn.
