I have been eating nothing but boiled beans with vegetables for the past 3 days is that good ?

I've decided to only eats beans boiled with veggies for about six months or until I lose about 10 lbs.So far I've had split peas,lentils and black eye peas.Tasted really good,want to stay away from meat. Could I stay eating like this for a long period of time,are their any side effects from eating this way?
