I don't know if it is possible, but I wanted to warn you against the pitfalls of such an aggressive plan.
Let's say you manage to succeed. Do you think you will be able to keep it off? Think about how hard you would need to work for it. Don't you think that, by the time your birthday comes, you would be in a constant state of craving that might become dangerous and ultimately lead to weight gain?
Let's say you do manage to succeed. How hard do you think that might be on your body? Don't you think this can be very detrimental to your general health? The only way you would manage is by spending a lot of calories while at the same time reducing your calorie intake through diet as well. Are you sure you want to expose your body to that?
Why not go for a more realistic 20?
