BMI,weight and height

Since yesterday I carried some baggage to the automobile trunk, I feel sharp pain on my back gradually becoming worse.
This kind of dysfunction must be caused by too much body weight, BMI number now is 28, ideal is 22 and 25 at the most.

I shall loose my weight in a month till 25, just by refraining from eating too much that enough according to my experience last year.
After loosing weight I would be able to keep a distance from all the diseases for geriatric.
