I don't know if the search will bring them up but I've posted in a bunch of atkins/ketosis threads which are basically low/no carb diets and the best way to lose weight, fastest aswell.
1lbs a week is a rubbish target, firstly you shouldn't put a target on as you'll only miss it and feel like crap. Some weeks you'll lose 4-5lbs, others you'll lose nothing or put a couple on, thats life, ignore it.
On a low carb diet(assuming you move from a high carb one) you'll have massive and quick weight loss, its water weight, don't get put off when the weight loss slows. You can literally lose 8-12lbs in the first week or two as for every gram of carb your body stores, it stores 3grams of water, you'll also pee like a crazy person for the first couple weeks. Your body stores a lot of carbs in muscle and liver, and a big guy will have a lot of stored carbs.
No carb is incredibly hard, low carb is easier but very difficult to adjust to as most people are used to eating a lot of carbs as we've had it drummed into us for years fats are bad, carbs are healthy.
Its completely incorrect and opposite infomation, you will die without eating fats, they are completely essential, even the "bad" fats are required to live healthily, just in smaller quantities, carbs serve no essential purpose, you CAN live perfectly fine without them though its very hard to live without them on anything but a weight loss diet.
If you manage to go a week or two on very low carb, you'll actually find your hunger will drop off, carbs increase your hunger, protein and fat curb hunger, keep you full for longer and you don't get the sugar levels spiking as sugar is introduced and removed, thats the main cause for constant hunger we bigger guys tend to have. Once you get into the zone, my appetite just dissappears and weight loss becomes very much easier.
The key is, when you have carbs, have "good" carbs, low GI, things that don't spike your insulin levels and blood sugar levels, basically when that happens your body says, store fats, reduce fat burning, and eat, 3 things you don't want to do when losing weight at all. When you don't spike your blood sugar and don't produce insulin your body tells itself to burn fat, save nothing, keep burning, use everything it can and that it doesn't require outside food sources.
Drink loads of water, keep topped up with vitamin B12(all the b's) as the process your body creates energy to burn fat uses the b vitamins, running out reduces the amount of fat your body can burn.
Egg's are great, scrambled eggs on their own, on a slice of wholewheat bread, with chilli's, peppers, spinach or something stirfried in to make tastier egg meals. Egg's are fantastic for weight loss, good quality fats, filling, healthy, load of B vitamins, no carbs, taste good, relatively cheap, easy to cook, very quick to cook, basically good all around.
Look around some weight lifting/dieting sites, find ones you like with good advice, personally most diet/nutrition sites are filled with "fad of the month" diets, and most weigth lifting sights are filled with guys who have worked out and maintained healthy weights for years and tend to know what works, rather than what a house wife has done for 3 months.
As said before though, don't set targets, if you think you're going to lose 2lbs a week, and you don't, you'll feel crap, if you lose 4lbs and think you're doing great compared to 2lbs a week you thought you'd lose, then the next week you don't lose anything you'll feel like crap.
GO into it knowing some weeks will be good, others will be bad, eat well, do research, work out what food are good, read up on good/bad carbs and find some you like.
I always ate pizza, white bread, and that was about my diet, I never liked brown bread and it took a while of trying lots of different types before I found something healthy that I also liked. I like wheatgerm bread, Hovis, has that moist softness of whitebread but its far healthier. But in general I minimise the bread I eat.
Protein shakes aren't a bad idea, I found them easy, easy to flavour, quick to make/drink and also helps you have a small but nutritious hit of protein. I hate cooking 4-5 times a day in small amounts, so shakes let you do something small, quick, healthy inbetween meals.
And good luck.
