What was your diet/secret?
I need to lose ~50lbs

First, change what and how you eat. Eat 4-6 meals a day, spaced at 3-4 hour intervals (no longer). The meals should be smaller and should be healthy foods (low fat meats like fish, poultry and some cuts of beef, complex carbs like brown rice, whole grain breads etc..), no simple sugars, no high fat meals. Try to keep your meals to about 30g of carbs or less and 6g of fat or less. Make a fist, that should be the ammount of complex carbs you have at each meal/snack. Now hold your hand out flat, you can have poultry/fish servings the size of your palm from the base to the middle knuckle and red meat servings the size of your palm from the base to the first knuckle (the lowest knuckle where your fingers meet your palm). Your last meal of the day shouldn't contain any carbs or be very low in carbs. Think low-fat cottage cheese or Tuna for the last meal. You should also be eating 1 gram of protein per pound of body weight per day, spread out over each meal (use your target weight to calculate this, not your current overweight measurement).
Once a week have a meal or a snack where you eat anything you like. It helps keep burnout away.
Excercise. A lot. 30-40 minutes of cardio 5-6 times a week. Lift weights, 30 minutes of lifting three times a week (in addition to the cardio). Biking and eleptical machines are good cardio workouts and are easy on your joints (a big concern for us big guys).
Most importantly you have to stick to it. No rationalizing a donut or a snack at work. No being lazy and skipping a workout. I've skipped maybe four workouts (not counting a couple of trips out of town) in the last five months. After working out have a protein shake, I recommend Designer Protein w/ 1% or skim milk.
Once you get a month or two in it'll become habit and if you've stuck with it the results will keep you going. I steadily loose 2-4lbs. per week on this diet.
Oh yeah, I'm also using a thermogenic (Hydroxycut, Ripped Fuel, Diet Fuel, Xenadrine RFA-1). You should do about a month on (follow the directions, DO NOT overdose) and about a week off. Switch brands each time. If ephedra scares you then do some research on it. All the research I've seen has shown that if you're heart healthy to begin with and you don't abuse it (overdose) then you'll be fine. Stastically driving to work is more dangerous (for me) than taking ephedra.
One last thing, this whole proccess is much easier to follow if you have someone tracking you and making you accountable. It's not easy doing stuff like this alone. Tell yourself, if you give up then you're accepting that you're going to be fat for LIFE. This chance is your ONLY chance. Don't give yourself any other options. Loose the weight THIS time, or live with it FOREVER. That really motivated me.
Shutting up now.
