though I havent read the book, I read a study myself that said all weight loss is is calories in vs calories out.
I was told by my doctor that I would die by my mid 40's or have to be on maintenance drugs for the rest of my life, I was 303, and this was on August 31 2009.
Now, as of today I am 270 lbs, well on my way downward in weight.
I didnt eat any fancy foods, healthy foods, whole grain, or any of that. I tried that once and so hated my life I failed over and over to lose weight.
Instead I simply ate less of what I like, and made sure to calculate calories as well as I can and I started doing a little bit of exercise, about 300 calories a day (easy to do, just some small amount of walking).
I dont even need the exercise, I lost nearly 15 lbs without exercise. It is all calories in and calories out.
What I also hate is these advertisements where they argue "lose 20 lbs in a month!"
The first 20lbs is easy, just put the fork down and don't eat so much.
Its the next 20 thats hard.
