The standard Ketogenic diet is based on approximately 70% fat, 20% protein and 10% carbs, the decrease in carb intake makes your body enter in the metabolic state of ketosis by which your body turns fat into energy more efficiently using ketones. Ketones are produced in the liver from fat. In other words, your body doesn’t have any other option but burning fat all day to keep you working. Sounds like a good diet to lose weight as it relies mainly on fat burning.

Pros and Cons of the Keto Diet:


Among the benefits/ advantages, the Keto diet can:

  • Reduce blood sugar levels thanks to reduction in carbs intake.
  • Produce weight loss as body fat is used for energy supply.
  • Improve mental performance: ketosis results in a continuous flow of ketones to the brain consequently avoiding issues related to blood sugar spikes. This may improve your concentration and focus.
  • Help with diabetes: ketosis lowers blood-sugar levels and reduces the negative impact of high insulin levels.
  • Help normalize appetite: fat is naturally more satisfying and thus makes you feel full for longer.
  • Help reduce seizures in people with epilepsy, mainly children.


These are some side effects when entering ketosis, at least during the first period:

  • The “Keto flu”: you may feel tired and sick as your body now lacks sugar and uses fat to gain energy. These feelings might be persistent at the beginning and tend to disappear as your body adapts to ketosis.
  • Bad breath: also known as “keto breath”, it’s a typical sign of a ketosis state as you now have high ketone levels.
  • Increased heart rate: you may feel your heartbeat goes faster as you aren’t eating enough salt and you might be dehydrated. Try adding extra salt, magnesium and water.
  • Constipation: going keto implies a big shift in your daily intake, this may affect your digestive tract. Now, you’re eating less carbs and fiber and high amounts of fat. But, fear not, this only lasts for some weeks until your body goes through the transition.

Keep in mind that all these effects are quite normal and disappear in the short run.

Keto Diet and Physical Activity

What’s the keto diet like when you have to adjust it to your energy needs being an athlete?

Keep in mind that your body now is not receiving carbs so you can feel a bit tired and with low energy. Keto diet is based on low carb and little protein intake which are both essential to produce energy and build your muscles. When your body enters ketosis, it now uses ketones from fat as fuel source, this means a big change as carbs are the preferred element to boost energy.

That’s why it’s not recommended doing high intensity activities such as spinning, crossfit, running, kickboxing or jumping the rope as your performance may be limited due to lack of carbs. You rather choose yoga, pilates, or jogging instead. These activities will make you feel active and not tired so you’re not going to blame the keto diet for not moving your body. It’s important that you always include some physical activity in your life along with any nutrition plan.

Now, if you are an athlete and you need to be active and ready to run long distances or training hard, you can add more proteins and some more carbs to your daily intake. Be sure to talk to your doctor and coach to keep a balance between diet and training.
