A common misconception The Fat Decimator Review is that there is a best diet out there for everyone, that through some tweak we can make everyone live longer and achieve maximum physical condition by feeding them the perfectly optimized diet. I imagine this as the food bar of the future that is closely related to meal bar often served in prison. This may be somewhat of an iron curtain type view but it is fueled by numerous people trying to determine what they need to eat to loose weight but still not taking action.
My simple answer is that diet depends. There are countless factors that go into choosing a healthy diet that maximizes a persons genetic profile and yes people respond to the same diet differently because of their particular genetic makeup. An Alaskan Native who's ancestors have been subsisting on a diet heavy in whale blubber for the last few thousand years will have substantially different requirements than a hunter gather from Papau New Guinea. It is asonine to think that everyone can thrive on a fast food standard American diet. It is not the least bit surprising that we are plagued by health problems that can be easily solved by diet.
