Green lentils?

My mom makes this great lentil soup...I was wondering if green lentils are healthy? I want to eat that soup for a whole week I can never get sick of it it's verrry delicious it's actually called "lebanese lentil soup"...if anyone has tried it I would like to know if you can actually lose weight off it if you were to eat it for a whole week. Please, I need your help!
