Start an activity that does not require extra equipment because the student is actually doing the work. You can conduct as much research as you want but that doesn't mean the student will actually do the activities.
Watch motivational videos and search for some workouts specifically for your problem. What I would suggest is to get a fitness trainer but if that is out of the budget, get in groups and do sone exercises with your friends and share exercises to do together. It's more fun that way. Or if your an introvert use dance fitness it's kinda fun or zumba, which is kinda the same. Eat healthier and more meat as it helps you to be full. Remember with reward comes patience, the more you push yourself the better you get it.
It ain't easy, trust me.
