This is going to sound extremely boring, but: just drink a lot more water than you have been. Try that for a couple of days. Then see if, all other things being equal, you don't feel more energetic.
You'll most likely lose some weight along the way. Like I said, it's a very boring solution (surprisingly hard to do it, too, if you're not used to drinking water a lot) without the bells and whistles of diets. Think of going to the hospital and being replenished with an IV. Think of dogs, so full of energy, constantly lapping up water (and constantly having to be taken for walks or go outside so they can pee...). It helps energy levels a lot because you can be mildly dehydrated and not really know that you are.
