Hi Porkchop!
Welcome to the 100lb club - we all understand what it is like to need to lose 100lb or more. I know it seems an overwhelming task, but it can be done - there are a lot of people who have lost 50, 100, 180lb who still hang around here to offer valuable support and advice.
My advice is:
Focus on small targets and just aim for each one of them - it will soon add up! Take one day at a time, one meal at a time .
Write down everything you eat and the calories (or points if you decide to do weightwatchers) - it can be a real eye opener!
Get as much help and advice as you can here and by general reading - decide on a plan that you feel you can stick to and that is not too restrictive.
Some people prefer to take it slow and make small changes week by week, others prefer to launch into it all straight away - decide which you prefer and work it into your plan.
Start to exercise - however short to start with, just start moving a bit more.
Drink lots of water!
That's enough to get you started and get those pounds dropping off!
Good Luck
