Welcome, Rakgadi.

I imagine you'll have heard of Professor Tim Noakes from Cape Town? His Real Meal Revolution website was the first low carb resource that I was ever referred to. His work has since gone a long way to absolutely changing my life.

12kg in 3 months is a steep challenge, but not impossible. I managed an average of 1kg/week for about 8 months for a while there, but then I had a lot more to lose in the first place as well. I'm sure you'll give it your best shot.

Good luck to you in reaching your goal.
