I had that test done. The disclaimers and warnings left me a bit sceptical (while taking the test). The test giver could not explain why I need to sign a disclaimer and what the potential cause of death would be from...
That's why I wanted to use the formula and do the math myself. That test left me feeling dazzled. The other thing about it is that your calorie needs will change as you loose weight, so unless you are willing to keep spending that money, it is good to have a formula that works.
I decide to start at 1200 for 6 days and keep adding 200 per week until I get the results I need for 2lbs weight lost per week.
So far, so good. And I've flushed my system of sugar cravings in the process.
