*LONG POST ALERT*
Some of the information in this thread has been good, and some not so good (IMHO). I am not a nutritionist or a doctor, but I am 6'0", and was able to go from 300lbs to 180lbs and keep it off for 11 years now (I'm 30). I was fat all my life and just got tired of it. On my my 19th birthday, naked in front of a mirror with a 54" waist I decided to change my life. Here's how I did it:
You must be willing to make permanent "lifestyle" changes for the weight loss to be permanent. Forget the idea of going on a 'diet', we are all on diets, they just suck!! My way of eating takes into account that there will be days that you eat everything you "shouldn't" be eating, but we gotta be real! Holiday parties, events, etc will always be a constant threat to any sound eating plan. The trick is to enjoy those "days off", and then get right back on track. One or two days a month of all-out eating will have little to no effect on your weight-loss goals.
Basic principles: These are not open to discussion or alteration. (In no particular order)
You will read the label of everthing you eat from now on. Check the calorie count on a Little Debbie or Hostess honey bun and you'll see why.
Any liquid you drink should be very low calorie or calorie free, period. Diet soda, water, crystal light, flavored waters, SKIM milk, diet snapple etc. A can of soda has @200 calories, about 10% of your days calories!!
You will no longer eat regular mayonnaise or salad dressing or butter under any circumstances, period. Lite or fat-free ONLY (preferably FF) PARKAY and I Can't Believe It's Not Butter brands make calorie butter free sprays that taste excellent!
You will never eat a hot-dog again, period. Fat-free dogs only.
You will use olive oil only. It has the "good fat" we all need.
You will no longer eat added table sugar in anything you eat, period. You will use Splenda brand sugar substitute. It's calorie free and tastes nearly like sugar. You will substitute Splenda for sugar in coffee, tea, cereal, baking cookies, cakes etc.
Eat EGGBEATERS instead of regular eggs. They have 1/2 the calories, zero fat and zero cholesterol.
Take Centrum Silver or another good multi-vitamin everyday.
You will limit the amount of packaged food you eat. If it comes in a box and can be heated and eaten in 10 minutes, it proabaly ain't so good for you.
Exercise MUST become part of your regular schedule. Aim for 2-3 days a week of 30-60 minutes of cardio. Do the elliptical for 20min, the bike for 20 min, and the treadmill for 20min. Whatever you choose, keep it varied and keep your heart up so you sweat! Basketball, jogging, exercise classes, it really makes no difference what you do as long as you are consistent. Pick up a copy of Men's Health for plenty of workout routines.
Some would say that 4-5 days a week of exercise would better, and they are absolutely correct. The problem is that it is hard to maintain that kind of regimen. I attempt to ask for a realistic amount of exercise that no one can say they do not have time to complete. Consistency is the key here!
Foods I eat in EXTREMELY limited quantity(1X a week or less)
Anything with lots of added sugar
Bread
Pasta
Rice
Potatoes
Any food high in saturated fat
Full-fat cheese
Foods I eat regularly
Oatmeal
Cold cereal with no added sugar
Chicken
Salmon
Turkey
Lean Ham
Beef or Turkey Jerky
Nutrition Bars
Reduced Fat Peanut Butter
Salad
Vegetables
Fruits
Almonds and Cashews
Skim milk
Tea/Coffee/Flavored water
Low fat cheese/salad dressing
Foods low in saturated fat
I do not count calories, I just eat normal sized servings of food and have huge salads almost everyday. I think that the best way to characterize my diet would be to call it a "low glycemic index" way of eating.

If you read the South Beach Diet, you will find it very similar to mine. Too bad I didn't write the book! If you need a regimen to follow, this book is pretty well balanced and the diet is easy to follow. Forget Atkins, it is just too restrictive and besides, it makes you constipated!
Of all diets to follow, I think Weight Watches is the most logical because you can eat anything you want, just not a plate-full of it!
Helpful Hints:
As for weight loss, you must make a monthly chart of your weight and your weekly goals. Weigh the SAME DAY AND TIME every week and RECORD YOUR WEIGHT. This process will force you to think twice before you eat too much when you know your weigh-in is only two days away. Put the chart on your refrigerator or desk at work so you see it a lot.
Aim to lose about 10 pounds a month the first two months and then about 6-8 for all subsequent months. If you follow everything I did, especially the working out, you will easily lose the first 20 pounds in two months.
Tell everyone you know you are on a diet. You wil be surprised how supportive they will be.
Tell your spouse, buddies or siblings to join you in your new way of eating. Challenge each other to see who can get in the best shape first, and wager some cash on it!!
Take that pair of pants that no longer fit and put them front and center in your closet. Try them on every week to see how close you are getting to wearing them again. This a great motivator!
Schedule your exercise the same way you would any other important meeting. What is more inportant than your health anyway?
Don't think of this as a diet. Think of it as preparation for old age! Sounds silly right? Well believe me, there are people who are 60 years old at my gym who are in significantly better shape than than most teens because they eat right and exercise regularly. You cannot wait until you are old to get in shape, by then it is too late!
No matter how much you stray from your new way of eating, remember that you can always go back. One day, two days or two weeks of binging on sweets and fatty foods is just a blip in time if you can maintain good eating habits for most of the time.
Give yourself time to lose weight. You didn't gain it overnight, did ya?
Plan a vacation to a place you would normally take your shirt off. You want some motivation, you got it!
Vary your exercise routine so you do not get bored. If not, the couch and remote will look more and more appealing as time passes.
Realize that you can go to parties, fast food restaurants, and even Tavern on The Green and not eat like it is your last meal. Just because everyone is gorging themselves doesn't mean you have to.
Purge your kitchen of all the no-no foods on the list. If it isn't there you can't eat it.
Eat breakfast. I know we have all heard this a thousand times but it is true. If you eat breakfast you will eat less throughout the day, and are therefore less likely to binge later.
This is most of what I have done and it works. I had gained about 40 pounds in the last 1.5 years after my marriage as my wife insisted on making three course meals on a daily basis. That led to less working out and before I knew it, I was up to 220 again. I realized I was back to pasta and rice almost daily, as well as rich desserts all to frequently.
On September 1st 2003, I started back on my eating plan. I have lost 25 pounds so far, and will have lost the last 15 by the time my birthday comes on Feb 7th.
I had been thin for so long that I figured I could eat like I used to, but I was just fooling myself. My wife now cooks only the foods I can eat so there is no temptation to stray. I can't wait to gat back into my waist 34 Levis!! (they are at the front of my closet to remind me!)
Good luck to all in the battle of the bulge and I would be happy to provide more info on my eating plan if desired.
