My doctor put me on a diet and at least for me, when a professional tells me I must do something, it carries more weight on me than my own decision about it.
What he told me was to stop eating bread and potatos, and focus on meat and plant matter. (I believe it is called the akins diet)
However, over the last three weeks, I am down two pant sizes. Even better, this diet is easy as there is plenty of yummy nonbread things in the world. Second, this doesn't require much in the way of special planning. I just replace bread or potato based side dishes with something else, such as cheesy brocali. Thirdly, there are plenty of things at restaurants I can eat with no special fuss.
I like stuff that requires no work since I am already a very busy person.
Of course weight loss will slow down, the first few pounds are always the easiest, but this is something I think I can actually do and maintain discipline on (and I am bad with discipline when it comes to food)
