I have an allergy to fruit and i eat so much junk food but i am still losing weight!?

See Allergist: It is unlikely that you are allergic to all fruit so seeing an Allergist for further workup and testing would be beneficial to determine exactly what you are and aren't allergic to. A diet heavy in junk food provides little nutrition. Would suggest substituting more vegetables, lean meats, and once seen by Allergist, fruits. To gain weight safely, working with a nutritionist can be helpful.
