The keto diet, as a rule, is very low in carbs, high in fat and moderate in protein.
When following a ketogenic diet, carbs are typically reduced to under 50 grams per day, though stricter and looser versions of the diet exist.
Fats should replace the majority of cut carbs and deliver approximately 75% of your total calorie intake.
Proteins should account for around 20% of energy needs, while carbs are usually restricted to 5%.
This carb reduction forces your body to rely on fats for its main energy source instead of glucose — a process known as ketosis.
While in ketosis, your body uses ketones — molecules produced in the liver from fats when glucose is limited — as an alternate fuel source.
