1 more please-
I am in the same boat as you.... With less time.
I have heard that 1 kilo per week is a healthy weight loss- so 10 kilos in 11 weeks may be do-able.

I don't think I could stomach the shakes as I am a sooky when it comes to taste.

I am looking into light n easy.
It is quite pricey.

Another option is to use a calorie counter on the computer or iPhone and exercise more frequently.
