A ketogenic diet is free from any side effects and completely safe for fat loss purposes. However, when it comes to long-termfitness goals, one must recognise that the Keto diet depends upon the Ketosis state which is a high metabolic state. This cannot be maintained on a long-term level. By doing so, it creates a perfect opportunity to lose body fat by converting fat into an energy source. This is purely natural without the use of any supplementation. However, to reach such a stage one has to sustain the Ketosis state.
