I lost 10 kilograms in 12 weeks with the CSIRO well being diet. Look it up on the internet. It is red meat heavy, but if you substitute some of the meals with fish, chicken or soup it's great and you don't even know you're on a diet.
My wife lost 8 kilogram and she's looking great. Now if I can just grow some hair on my head .....
Also, golden rules, drink lots of water, exercise, look out for any change in health and play your TELE!
