Lack of motivation

[Wisemon]

That's not true. And your case it's different from his; you have a base problem. The true 'lifelong war' is the person that was always fat, ever since his birth; and his is a time in his life where he feels unconfortable and makes a click and gains lots of weight. Once his problems go away, his overweight will go too.
(And I will like to chat some more, but I'm running out of credit).

The way I phrased it isn't how the Weight Watchers people phrase it, but it's the same sentiment. You have to stick with your diet for it to work. That's why it's called a diet.

when I'm stressed I like to eat, and I like to eat fatty stuff. Which is not so good

I have the same problem. I recommend Turkey Hill's Fat Free No Sugar Added Ice Cream, or just eat some pickles and carrot sticks.
