It is expensive but seems very thorough. The initial £299 is for the tests. This involves a glucose monitor which is ‘connected’ to them, eating the supplied muffins for breakfast and lunch on first day then doing a blood test at a set time. Also a poo test, which is made easier with everything supplied in order for the minimum of fuss! After these have been analysed (few weeks) a very comprehensive set of results are issued. After this the monthly plan begins, which involves an app in conjunction with your test results. I now now my blood sugar response is poor and my blood fat is bad. My gut microbiology is ok compared to a high percentage of the population. Food scores are personalised so I know what to eat. Not everything we think of as good is for everyone and conversely with food we think of as bad.
I’m only a few days in so can’t say what, if any, impact it’s having but reviews are mostly good.
