I am hoping to help my sister who has experienced chronic fatigue for five years. She has been seeing a GP but has shown no great improvement in energy levels (spends majority of time in bed) and developed greater health problems with a large weight gain (approx 20kg in one year) and associated issues with being overweight. Am interested in suggesting to her the 12 week fast 800 diet to reduce her weight but should she be doing the clever guts diet first to treat her gut? At the moment her exercise capabilities are also limited due to low energy levels. Has anyone else suffered from chronic fatigue and had good results following these diet recommendations? Are there any recommendations for a GP who has assisted with this program /or the testing or helped someone else with chronic fatigue and had positive results within Perth, Western Australia. Is testing for individual diets now available within Perth/Australia or if not when will this be available. Thanks.
