Hi Fazloon, your weight gain in that 1 year is big. Try to think back what changed in your lifestyle, diet or health that could have led to this? That would be a good start. If you can figure out what changes in your lifestyle or diet that caused this weight gain, then you will know what to do to reverse that weight gain. If you cannot figure out what caused this sudden big weight gain, I suggest you consult a medical doctor or get a thorough medical check up, just to confirm that it is not caused by a health problem (such as glandular problems). Wish you the best in your efforts to have a healthy life.
