I don't have a named plan, but in the course of changing everything I've:

+ cut out blatant sugars (splenda in my coffee, fruit instead of sweets)
+ switched to non or low fat products (soups, canned products, dairy, etc.)
+ substitute soy for milk (part milk allergy, part calories)
+ cut down on calories and sodium- aiming for 1200-1400 calories. Sometimes I fall short and need to start calorie counting, but otherwise it's pretty easy.
+ Cut portions down to size.
+ Cut out white rice and bread (I love brown rice and flax bread)
+ Substitute tofu noodles for regular noodles.
+ I stay away from spaghetti sauce for lack of control.
+ Snack with veggies with salad dressing, fruit, hummus, etc.
+ Eat before 8-9pm at the latest.
+ Cut out soda and fruit juice (high sugar)

I count calories. 1800 a day. I also try and stick close to the American Heart Assc. plan. So 5 fruits and vegetables, stay low fat, eat fish one to two times a week and sometimes I go one day vegetarian. I also will treat myself once a week but you need to be careful with that. It can send some into a binge and has me a time or two. I like to still count calories on that day and just allow myself the normal 2700 calories they say a man should eat. That gives me 900 extra to play with.

gosh...I have tried so many things and they were all crap!!! (meaning: it didn't work for me)

BUT...one thing that seems to be a constant...that pops up in almost every weight loss success story is the ONE THING I hav'nt done...keeping a food/exercise journal...

so that is my new plan...a journal tracking my eating habits , calories, carbs, protein and fat....I will also track my success and I will be able to see ON PAPER what is working and what is not...I will also be tracking my exercise.

also I am eating more high nutrition low cal foods like veggies and fruits and lean protein and whey protein.

I don't do a formal plan. I watch sodium, animal protein, and try to eat only healthy things. I fall off the wagon sometimes like everyone else.
