Hi Changing

Welcome to the forum.
I have found that the best thing I could do is to keep track of my
calories, (as much as I didn't want to!) By doing that, I was able to see and get comfortable with knowing what a portion or serving size really is. Surprisingly enough, a serving size is NOT the entire can of pringles like it used to be for me
Since I've been losing and watching my
calories & portion size, I do find that I am hungry about every two hours. So I just make sure I have snacks (fruit, power bars, etc) with me. If I eat about 200
calories or so, I'm good until the next "meal" and I don't binge eat anymore because I haven't starved myself all day.
As for starting back at square 1, you're not. You're 14
pounds lighter then you were at your heaviest - you didn't gain it all back and then some.
As for what SS said regarding the amount of food you'll be having and the
calories burned, I guess it depends on your total daily intake...but based on your current weight, you could eat 2352
calories to maintain, 1852 a day to lose 1
pound a week, and 1352
calories a day to lose 2
pounds a week - not counting your excercise. Do you have any idea how many
calories your current plan will give you?
Good luck and this is a great place to start your journey!
