How often you measure your body weight?

Yes I measure my body weight at least once every fortnight. I have light weighing machine at my home, so no need to go to railway station or any medical centre for checking. This keeps me health-concious. My weight differes between 1-2 kgs more or less. I control weight by balanced diet, pranayama, yoga, light exercise, walking etc. I give stress on food quality not quantity. It is spicy food which keeps us overweight. As it is tasty in eating, we eat without taking care of quantity resulting into overweight.
