Welcome to the huff and puff room. Glad you are wanting to make positive changes.
First off, start slow. Don't look at the 30lbs but set small goals for yourself like 4-5lbs per month so it will be effective weight loss. If the goal is only to lose weight I would do a lot of cardio but again start slow. If you can run one mile do that 3-4 times the first week then try to add a little more the second week and so on. If you want to lift I would do high rep lower weight stuff to work out.
Also, the died is important here. Most Americans eat too many carbs, as you've probably heard, so you may want to scale them down and add more fruits and vegies which have a different carbohydrate then breads.
This is a start and more can be added. Be patient, it's a process but a rewarding one. God bless.
