Hi,
What is it that you want to achieve? Do you eat too much, eat irregularly/on the go, eat out or get takeaways, hate fruit and veg, too busy to prepare food..? If you give us a few ideas about what your problems are then maybe we can help give you the inspiration you're after.
I did it when I had a lightbulb moment. I managed to wedge myself between my coffee table and tv unit and had to be rescued by my husband. That's pretty depressing (although now I think it's hilarious 
) So, I threw out the junk that was in my house - the chips, doughnuts, onion rings, crisps etc and ate what was left. I started eating breakfast, proper breakfast not crisps and dairy milk. Learned about portion sizes and started weighing my rice, pasta, potatoes etc. And I started walking, set a timer for 5 minutes and walked away from my house, when the alarm went off I turned round and walked back. Did that until it got easy then upped it to 7 minutes and so on. It sounds pretty dull but I eat more variety and am more adventurous with food now than I ever was before. Healthy eating can be delicious, inexpensive and simple to prepare.
To get going you could have a look at healthy versions of foods you really like, so you're not changing too much too quickly maybe you're just changing the salt/sugar/fat content, adding more veg or changing the preparation method. Sorry that's a bit vague but there's no point rattling on too much until we know what you're looking for!
