Would you rather learn to accelerate and control an unstable mass in free space when your body is weak and your nervous system like a sponge, or after you've actually built enough strength to hurt yourself?
This is one of the absolute most deleterious notions in the fitness industry. The truth is, things should go the other way. Only once you've progressed past the beginning stages as a lifter, and developed some coordination with basic lifts, should machines become a consideration.
Learn to move your body dynamically in free space. Unless you have some kind of disability that prevents it, which I assume you would have mentioned.
Also, eating less than 1000 calories per day is not a good idea. As you begin to learn some basics about feeding yourself appropriately, that will become obvious.
Best of luck.
