Awesome. I think if you modify what you were diong you coud easily feel full and not exausted.
First off.....that is way too much whey protein.....get rid of 4 to 5 of those 6 scoops and fill it with real food. You could use cottage cheese or yogurt in place of it and feel fuller.
see this is interesting. I feel fuller when I have a whey shake before a meal.
Now....out of any food in the world.....per calorie nothing fills me up more than an apple. Make sure you are eating the skin though because it has a ton of fiber that will slow digestion giving you energy over a longer period of time (feel free to correct me if i am wrong anyone

).
You're not wrong if you feel fuller after eating an apple. You're a lot different from me, though. I'm hungrier if I eat an apple than I am if I eat nothing at all. Nothing makes me hungrier than an apple. If it works for you though, go for it. I wish it did the same for me as it does for you.
In place of another one of those protein shakes you can eat some nuts. Why? Because you aren't getting any fat in that diet!!!! Your body is going to make you hungry because you are depriving it of necessities. Fish oils are great too.....mayswell add a few too each of those fatless meals

.
Fish oils and fatty nuts can indeed help some folks with satiety - but watch it - nuts are high in calories, and they add up fast.
Another replacement for all that whey would be a banana! If i was you i would eat a banana, apple, and an orange everyday. Throw a tablespoon of peanut butter on your banana and you have a healthy snack at under 200 calories.
Peanut butter on a banana makes for a fructose, starch and fatty snack that's LOADED with calories. It may fill YOU up, but it may not fill up the OP. Generally, sugars and fats with low protein does not induce much satiety.
I am no doctor or anything but you gotta make a diet that is sustainable for you and not forget about fruit and fat. Heck....I am popping 5 fish caps to go with my brown rice, brocolli, and Tilapia cuz there is isn't much fat happening.
I do generally agree with you regarding the fats - and it's good of you to share your experience. Taiyed, out of curiosity, have you ever been fat before? I wonder if it's different for former fatties than it is for those who have never been fat?
michelleshonk, start weighing your food. Track your intake and report back your total calories, and grams protein, carb and fat.
Also, I highly recommend avoiding starches and sugars for the first meals of the day - they stimulate too much appetite in many of us. I'd also suggest you concentrate your food into three or at most four meals a day, with no snacking. Let yourself feel FULL when you eat. Then brush your teeth and wait until you're actually hungry again to eat another MEAL. Snacking never lets your body know it's been fed, and you'll just stay hungry all day.
I know I have a rep for being anti-cardio, and I'm afraid I don't much care for it, but walking is good for you. Intense cardio isn't a great idea while you're fat though - it can overstimulate appetite, it doesn't burn all that much, and if you're doing something like jogging, it's really hard on your joints. Get some dumbbells up to 30 lbs in 5-lb increments and use those to train at home. They won't cost you much and you'll get a lot more out of that than you will any cardio programme.
