I have to reduce over 20 kgs in a month ? can anyone help me?

Standard weight depends upon the height. So, first decide- what should be your weight according to your height? Then decide how much you have to reduce? Without knowing this basic fact, any action to reduce 20 kgs suddenly will be risky. If you are overweight try to reduce it slowly and gradually. Avoid oily, greasy, spicy and junk foods. Take proper diet on proper time. Make a routine and follow it strictly. Do'nt try dieting. Take a gl of luke warm water, pore juice of one lemon, mix 1 table spoonful of honey and drink it daily morning empty stomach. No need of heavy exercise, just half an hour walk before sunrise will be sufficient.
