Im new at this

Hi everyone,
I joined ages ago but never tried this before.
So my story is that I just keep eating and eating, and off course, putting on weight.
the worse thing is that I know what Im doing wrong but I just cant stop. I buy fruits and they just sit there until they rot and then out to the trash they go.
Chips and cake are my weakness. To my credit I haven't bought these guys for while now but I I dream about them all the time. Especially Lays bar-b-que flavor chips.

Now I have come to the point where enough is enough. Even my fat jeans don't fit me anymore.
I want to try and loose at least 50lbs and keep it off.

Any tips and help would be greatly appreciated.
thanks
Asfia
