Have you talked to your Dr about a lifestyle or diet plan that works specifically for you? That could be a game changer. Lots of great advice on this thread but also vastly different. Some people can't tolerate fruits/veggies, others need a lot of protein, blood-sugar/cholesterol/triglycerides/etc should all be taken into consideration. Regardless of how you choose to alter how & what you eat, upping your activity level is necessary as well as being mindful of why you're eating (truly hungry, bored/stressed, it's noon, therefore "time" for lunch, etc).
