I've had to learn that there is a difference between gaining mass through fat, protein, and now what appears to be gaining mass through sulfur oddly enough.
I've learned and studied that sulfur is a substance that helps to 'bind stuff' and proteins together, so may turn out to be just as important as some healthy fats and proteins in maintaining a beautiful weight and body mass.
When I consumed fats to gain weight mainly, then it made my face a bit fat. But now as I'm using a sulfur-based supplement, some healthy fats, and only some protein, it appears to be a good new step in the right direction.
