My friend keeps asking me to register the challenge with her, the package seem very attrative, pay only $85 for a package worth more than $200 and heard that can loose up to 8 kg in 7 days! Is it so effective? Can someone who has took part in the challenge share your experience? I would like to know more...

Dear florenceX, It's a pitty there are so many scam artiists around, to rob the blind! believe me, I know, because i quite often loose 2.5kg in one days work out! In fact I have just reduced my incredible 98kg of solid muscle, down to a nice acceptable 78kg in 16 weeks.
So a little eye opener for all the unknowledgable, is that 8kg of liquid is the only thing you are going to lose, and soon after they have taken your cash, you will probably put 10kg back on. There is only one way to lose weight and keep it off, and that is to change your eating habits, ensure your macronutrients are well balanced in your favour!
If your over weight, reduce your fat intake to around 15% , the government recommendation is around 40% protien 30%carbs and 30% fat, this in my opinion is still to high for the average lazy bones, keep fat down between 15 and 20% and exercise for 2 x 15 minutes if you have never exercised for a long time. take it slowly and you will see results within 10 days, you will have to increase your carbs.
Don't increase protein unless you intend to do weights, weights are also good for fat burning, but you need to exercise many muscle groups, squats with very little or no weight at all, is good, if you first get approval from your local GP if taking up exercise, heart failure can happen to anyone, if they have never been cleared for activity.
One doesn't even need a gym, try walking over the road bridges several times a day, this will also get your metabolic rate up, its important to sweat, once your sweating, your actually burning fat. rather than carbohydrates, around 45% of your maxium heart beat is enough to start with.
Believe me all diets work!! but they are all scams to take your money, all individuals will lose liquid first, and this can easy be up to 10kg in weight, then you have to start burning the fat. and FAT takes time, more than double the time of carbohydrates, which have 4 calories per gram, Fats have 9prgrm
