I know it's easier said than done for most of us, but excercise is the best way to loose weight.
Normally when people walk, they walk 10kms at a slow pace. Trust me this wont help you at all.
Our bodies are like cars, they spend most of their energy when work is done at a fast rate, like the car burns max fuel when the revvs are kept high.
Even if you can manage only a km a day, do it as fast as you can, brisk walk is anyday better than jogging. When jogging, you cover a lot of distance but it's like shifthing into 5th gear and cruising, your body isn't using much energy.
So no matter what cardio vascular excersice you do, do it as quickly as possible, but make sure you don't over do it.
How much weight you can lose also depends on your body type, there are three main types of body designs, if i can call it that.
1. Ectomorphs - these are the skinny kind of people who, no matter how much they eat have the ability to burn it all without much excercise. Eg: Basketball players
2. Mesomorphs - these are the medium sized people who have a body thats genetically inclined towards body definition. They can put on weight but can control it very easily. Eg: Gymnasts
2. Endomorphs - these are big guys, the Maybachs among human beings. They can put on a lot of weight in the shortest possible time and will have a hard time getting the fat out of their bodies. Eg: Sumo Wrestlers.
So for guys like you and me, excersice is not the only sollution, we also need to control our diet which unfortunately, we cannot

So, see what category you belong to, how many kgs overweight you are and go according to that.......best of luck.
Ok, now where r those weights of mine......... *
