Do you have a hard time gaining/retaining weight? If so just have to make sure you're Including weight training in your work out regimen. Also make sure you're eating more calories. There are plenty of vegan foods especially nuts and seeds that can assist you with that but you also need to know what you're allergic to. It can be healthy and still break you out if you're allergic.

Yes its hard, since like everything healthy i eat, like it dont full me, like still hungry, will look to calories healthy acne free foods,
