Fixed-resistance training machines consist of any of the devices you see on the gym floor that limit your range of motion in a determined path. The benefits of using these machines are that you can push or pull a lot of weight with less risk of injury in a predetermined, limited path. Theoretically, you can isolate whichever muscle(s) the machine is designed to target with less joint pain or irritation due to tendonitis in any stabilizer muscle(s). Of course the downside is that the stabilizer muscles will not be strengthened as much as would be the case free-motion resistance training.
Free-motion resistance training consists of any exercise such as free weights (i.e., dumbbells, barbells), flex bands, cables, bodyweight, etc. that does not limit your range of motion and is not restricted to a certain movement path. The benefits of this type of training is that you can strengthen not only the prime mover muscles but also the stabilizer muscles and you'll have the ability to perform a movement pattern unique to your joint movement. This type of training corresponds to how your body moves in life and is therefore conducive to functional training.
Which type of training type is better for you? The answer is that both can be good for the reasons previously stated. Consider incorporating both types of training techniques in your workouts. One strategy you might want to try is super-setting the fixed-path weight machine exercise with a free-path exercise. This allows you to push/pull a relatively heavy weight to target the prime mover muscle followed immediately with a free-motion movement to further fatigue the muscle along with surrounding stabilizer muscles.

"Motivation is what gets you started. Habit is what keeps you going."
The journey from fat to fit involves three major elements: resistance training, stretching and cardio training.

Ideally you should feel fairly hungry before you eat (i.e., 7 on a hunger scale of 1 to 10) and about 80% full after you eat (i.e., 2 or 3 on a hunger scale of 1 to 10). It is generally recommended you should eat some food every three to four hours to keep your blood sugar level fairly steady. Maintaining a steady blood sugar level is important since a low blood sugar level encourages a ravenous appetite and tends to lead to overeating.
Everything you need to know including recommended exercises and healthy foods to eat to get in better shape is nicely summarized in this graphic:
