“…The similarity in problems such as high protein and fat intakes was found among athletes from many countries. Based on the research data reported in the scientific literature, it has been stated that a diet high in protein and fat, but low in carbohydrates was adopted by professional athletes from countries such as Poland [ 15 , 16 ], Iran [ 17 ], Kuwait [ 18 ], England [ 19 , 20 ], Brazil [ 21 ], Greece [ 22 ], Australia [ 23 , 24 , 25 ], France [ 26 , 27 ] Finland [ 28 ], China [ 29 , 30 ], Ireland [ 31 ], Netherlands [ 32 ], Spain [ 33 , 34 ], the United States of America (USA) [ 35 ], South Africa [ 36 ], Canada [ 37 ].
