Alright, first step to losing weight is asking how much you want to lose. Determine if you want to look completely different, or stay around the same area, if you know what I mean. After you determine this, proceed to the fun stuff. Now, before you read this, you must realize that this is to be done after injecting a few horse tranquilizers.
If you are going for it all and want to lose a lot of weight, I would start by chainsawing off your left arm. Why your left arm, you say? More people are right handed, so you should save this arm. With the reduction of only one arm, that's a good 10 pounds. And you still can function the other! You can still fap, you can still shake hands.
If you want to go slowy, I suggest cutting off one finger a day from your left hand. After this, you may move to your toes on your left foot. This is for the turtle weight losers.
Now, what if THAT isn't enough? I suggest taking off your left leg. This will help drastically. Especially if your left arm is already gone.
Trust me, follow these steps and you will have a lot less body weight.
