I think what you should do now is to have a proper diet, especially something with high protein. Eat too much fat. Because I think you will never be fat, but the better and stronger one! Don't fall asleep after eating, that's not good.
So:
Your exercise should be done between 1 and 2 hours before meals. When eating, most nutrients will be absorbed by muscles, because you are exercising in front, and protein is the best nutrition for muscles. So as to achieve scientific and healthy obesity, that is, strong but not fat. But don't worry about building muscles. Its formation needs weight-bearing training.
Finally, I hope my answer can help you.
