Hey there, and
A lot of people combine the concepts of volumetrics into other plans, like Calorie Counting (I consider myself one of them...I love getting a big plate of food by filling up the plate with veggies and other low-calorie wonders). So look around.
We have forums by age range and amount to lose, also. Look around, settle in, and get to posting.
Can't wait to get to know you better!
