Okay so I've done a lot of research on this, one of the most important things is DO NOT starve yourself. That won't lead to sustainable wait loss. Also, excercize is really only a small portion of it. The main things is cutting out fats and more importantly, sugars. That means getting rid of all that hyper processed junk and switching to a more natural diet. When possible, maximize all natural ingredients. For ideas, I highly recommend checking out the books Everyday Detox and No Excuses Detox. While some of the stuff is quite frankly gross, it can give you some ideas about switching to a mostly or all natural diet. Hope this helped!
