I am a diabetic since more than 20 yrs and I am 74 yrs old.There is a discussion that a diet with 60 to 70% fat can take care of diabetes since there is no need for insulin.I read some where that such high dietary fat may adversely affect the gut flora which may in turn impact the mental balance.Fears were also expressed that the capacity of the liver to maintain a balance among all harmones is impaired.How far are these assumptions valid?Kindly enlighten.Thank you for your response.
