Could be normal. Sounds like your brother has a super fast metabolism, so it may be just that you have a RELATIVELY slower metabolism.

However, if you are really concerned, you can have your doctor check your thyroid gland. You may have an underactive thyroid, or hypothyroidism, which slows down your metabolism.

I think it's ok to have slow metabolism. Just eat what you need.
