Exercise only facilitates weight loss, actual weight loss comes from a healthy diet.
Only one thing you got to remember, burn more calories than you eat = weight loss.
Also weight lifting is a must when getting fit or trying to lose weight, id suggest getting a small dumbell set from decathlon or something and doing some compound weight routines 2-3 times a week.
All these machines are a waste of money, all you need is a good pair of running shoes and a park. If you dont like running outdoors then all you need is a tredmill and a dumbell set.
Also get your metabolism up, read up on nutrition and healthy diets.
Remember to eat a big breakfast followed by a meal every 3 hours, adjust your calorie intake according to the ammount of exercise you do.
And lastly don't over do it, remember to have at least a couple of rest days each week with plently of sleep.
