FREE online diet program?

I am looking for a free online diet program. Does acai berry or apple cider vinegar work? I have no willpower. I have a small trampoline that I am going to put together today. Supposed to be good exercise without all the jarring on the knees and hips. I do not want a diet plan that is foo foo food either. I am 62 and 60 overweight. HELP SOMEONE!!!
