– A dieta cetogênica é uma dieta rica em gordura e pobre em carboidrato, menos de 50g/d de carboidratos e mais de 75% de gordura. As dietas cetogênicas demonstraram o aumento no consumo de gorduras durante as atividades físicas e diminui o consumo energético de carboidratos, principalmente ao realizarem atividades de baixa intensidade. Portanto, essa dieta potencialmente pode ser indicada com o objetivo de evitar o esvaziamento glicogênico e aumentar o desempenho ou então reduzir a fadiga durante as atividades.
– Segundo os especialistas em nutrição esportiva esta dieta permite a perda de gordura corporal, mantendo a estrutura muscular construída pelo treinamento, sem prejudicar a performance. Entretanto, algumas diretrizes atuais não recomendam esta dieta para atletas de elite até que existam mais evidências sobre os efeitos colaterais e eficácia.
