It really only takes about 5 minutes to put your food in to my fitness pal each day. Pretty much every food is easy to search in there and if you are making the same meals frequently you can save them.
If you aren't going to figure out where you are at in the first place there's not really a good way to tell you how to move forward.
There are a billion different juice and smoothie recipes out there. Since you don't have any specific nutrition goals in mind you may as well just go try a bunch of them out and see what you like.
My smoothie recipe is pecans, chia seeds, baby spinach kale and chard, almond milk. You blend these together first. Add a heaping tablespoon of coconut oil, avocados, blueberries, blackberries, strawberries and ice. This along with some extra fat and protein and a multivitamin covers your bases pretty well for pretty much all of your micro nutrients and gives a good base for macros.
Don't be scared of weights, start with some light dumbells or just a bare barbell. Do squats deadlifts bench and overhead press. Hell 15 lb dumbells will turn in to a 300 lb squat in no time.
