Does anyone know of a good diet assistant? Something that will help me reduce my appitite?

I have been trying to loose weight for months, I can never seem to loose more than five pounds. I am looking to loose at least 20 pounds. I diet and exercise, does anyone know of a good herbal supplement, pill, anything that will help me loose more? I eat lots of fiber, protein and drink a lot of water still not helping. thanks!

What would be careers related to diet and exercise?

I want to go back to school but I want to find a career that suits my interests. Diet, exercise, and nurtition has always been a passion of mine. I attempted to get a degree as a physical therapist assistant, but for several reason that just doesn’t seem like something that can happen.

I also considered the personal trainer idea, but my brother said that there’s no money in it, especially in this state (Michigan)

Anyways, does anybody have any ideas of what I can look into or how to go about choosing a career?

Thanks for any helP!
