Adopting the keto diet is a demanding regimen. It requires you to cut your consumption of carbohydrates down almost to zero. Considering carbs exist in most of the foods we consume in the form of sugars — it can be difficult to stick to the diet.
Normally, the energy that the body uses to function comes from carbohydrates. But while on a keto diet, this energy is instead derived from proteins and fats.
Preparing a proper keto meal isn't necessarily more difficult than preparing a normal meal.
