Try to research clean eating and really give it a try! One big mind changer for me was watching a documentary called "Fat, sick and nearly dead". It has a large emphasis on juicing, but I would apply that to fresh, whole foods as well. Changing to this way of eating gave me a renewed energy and motivation to continue changing. I also love blogilates on youtube! As for jogging - try listening to your favorite music - puts me in my own zone where others tend to dissappear! Good luck to you, you can do anything you set your mind to!
Try doing a 3 day juice detox, they are great to kick start a new healthy life style. When you have finished your detox, just simply eat healthy, and not too much, and exersize 5+ hours a week. If on some days you don't feel like leaving the house to exersize, look at a YouTube channel called blogilates, she has loads of work out videos you can do at home without any equipment and they are really fun and motivating too
