is there any spells or something that I can use to gain weight? why? because I am underweight and I am in need of some body weight with stuffing my face with food. My folks wont approve of a 15 year girl under the knife for putting on weight.
You can write your own spell,and ask your prefered deity,or the watchtowers to help you regain health.
From a non-magickal perspective,search online for gaining meal plans.Try out the 'Myfitnesspal' app,which helps you track your food intake day by day.
If you have a serious eating disorder,consult with a doctor and therapist.
