You should take your temperature– aim for waking temps at or above 98.0 (take before you drink anything).
The things that I have found raise metabolism (temps, energy, general well-being) are making sure I get 8+ hours of sleep, eating a lot of carbs like potatoes and rice w/ salt or eating a lot of fruit. I was low-carb before and this made me pack on some weight at first, but it did start making me feel better immediately and look better over time.
Best of luck!
