Monkey, if you want it bad enough, you'll lose the weight.
My situation was that my BMI was 31.2, so it transpired I had to lose 7kg in about 5 weeks.
Guess what, I did it, in fact when I got weighed by the local guy in DXB I'd lost 9kg.
I lived on Tuna salads, and egg noodles for 5 weeks.. I also walked for 2 hrs a day at every opportunity after buying a book on body building diets and fat loss.
So if you want to..you can do it.
Just my 7kg's worth.
