text: is it okay to loose body fat while having a cold? before i started my cold (4 days ago) my body fat was %18.18 and today it is %16.94. before i weighed 108 and now i weigh 105. i am 16 years old (august 25, 1989) and 5'3.  i havn't been eating anything i dont normally eat. i know the normal body fat for my age is 15-24, but going down almost 2% scares me... your cold would have nothing to do with losing that much body fat, my question to you is...if you are 16 why in the world are you measuring body fat? you are still growing, dont worry about your percentage. worry about taking care of yourself to get over your cold, and just stay healthy. my suggestion to you would be even though you are sick, try to eat as much protein as possible, even if its just chicken broth, your body needs protein to create more cells and keep your muscle rather than burn it during a temporary reprieve from eating.
