People who get surgery for that, like the gastric bypass surgery lose weight fast - that is a drastic measure though (however, it is one of the few things that can completely put diabetes into remission)
This is something I used and it worked out. If you want to lose weight and go on a diet, you probably wil need to work out in this routine.
Push ups x35
Stretches x20
Jump n' Jacks x35 that's what I did for 20 minutes every day.
Here's 3.
Eat in moderation.
Exercise 4x a week for 45 minutes Eliminate lots sugar and sodas.
