If you want some good "free" exercise...
Try squats and forward/sideways lunges.
Do a set of 10 each a few times a day or something. Very simple to do, regardless of your size, my bride-to-be knows ALL about lunges, hehe. It seems easy at first, but about 5 into it, and you'll be sweating all over. Burns a lot of calories too.
If your knees and feet can take it, try using a skipping rope on a daily basis. The first time you use the rope you'll probably only last 5-10 seconds, (that's what happened to me) but keep at it and a week later you'll be away laughing. Within a month you'll be able to go for 5 minutes and then think to yourself, "shouldn't I be tired by now?".
Food choices are the obvious key. Bacon and eggs are fine, depending on how you cook them. Grill the bacon (no butter or oil required) and boil the eggs (they retain more of their goodness that way).
No food is bad, just be mindful of how you prepare it and what other options you have.
You could have a couple of biscuits for a snack, or an apple... but which one WON'T you regret as soon as you've finished it, which will fill you up more, which will take longer to eat?
The way I stopped eating biscuits was to bake them... sounds odd doesn't it? Well, when you know what's in a cookie... a pound of butter and three cups of sugar... it really turns you off. Or simply don't buy them anymore.
Drink plenty of water.
Some people say that you shouldn't weigh yourself. This is true to a certain point. When you are as overweight as we are (I was 126kg in January), the easiest way to see progress is on the scale. You will be losing FAT, sure you'll gain muscle, but when you're 120kg+ the fat will drop off. Measuring is good, but it is very difficult to be consistent if you measure too frequently. Once a month should be sufficent to eliminate the uncertainties of the measuring tape (like where you put it around your body, how tight etc) it can be very innacurrate.
You're going very well though, keep at it!
