The NASA workout

What do you do next?
After the initial test, it's recommended that you get retested after three months as most clients see visible results in this time period.

Plus, if your aim is to lose weight for a specific occasion or date, the programme allows you to accurately calculate daily weight loss so you can work out the exact timescale it will take to lose a specific amount of weight.

Proof it works!
'This machine cost me a lot of money; it was either going to make us or break us,' said Kevin Reynolds. 'I went purposely into ketosis by going on the Atkins diet to see if the machine works,' he says.

'I tested myself pre-Atkins and it showed that I was an 83 per cent carbohydrate burner. I knew that if this machine worked, it should show that I burn 100 per cent fat when I went into ketosis.' He continued, 'I went into ketosis, monitoring myself with ketosis urine dipsticks, and retested. My results showed that I was now a 100 per cent fat burner.'

Reynolds says, 'I was also able to accurately predict my weight loss for the following week; I knew I should be approximately 11 stone 2 pounds, and the following week I was 11 stone, 2 pounds and 10 ounces.' He concludes, 'that experiment proved to me that this machine was worth its weight in gold.'
