Is it wrong if I have low body temperature?

How low? A temperature slightly, up to 1 degree F, lower than the "normal" is okay if you have no symptoms.

Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
