OP, I would ask this; why did you work out at all to begin with? Just stopping all of your activities make me think you were doing them for the wrong reasons to begin with. You must find your motivation to do what you do. If you choose to do nothing then you will reap the consequences of that decision. You say you have low energy? Well duh! You were very active now you are not at all. What do you think will be the result? Find you motivation. When you get tired of being tired then you will do whatever motivates you, bike, run swim or whatever. You probably don't need a doctor, you need a mirror. What kind of person do you want to be? Overweight, lazy and low energy? If you choose to do nothing, then nothing is what you will get. As someone who has lost 30 pounds and re-amped myself physically, this is just my 2 cents...
