What is the Keto Diet and How Does the Keto Diet Work?
The ketogenic diet, more simply known as the keto diet, is a very low-carb, high-fat diet which shares many similarities with the Atkins and low-carb diets. This change in diet forces your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates in foods such as grains, legumes, vegetables, and fruits, the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat. This reduction in carbs puts your body into a metabolic state called ‘ketosis’. When this happens, your body becomes incredibly efficient at burning fat for energy.

Burning fat seems like an ideal way to lose pounds. But getting the liver to make ketone bodies is tricky since:
- It requires that you deprive yourself of carbohydrates, fewer than 20 to 50 grams of carbs per day (keep in mind that a medium-sized banana has about 27 grams of carbs).
- It typically takes a few days to reach a state of ketosis.
- Eating too much protein can interfere with ketosis.
Because the keto diet has such a high-fat requirement, followers must eat fat at each meal. To have a proper keto diet plan, expect to have a daily intake of a 2,000-calorie diet, which can consist of 165 grams of fat, 0 to 40 grams of carbs, and 75 grams of protein. However, the exact ratio depends on your particular needs and your fitness goals.
When you reach a state of ketosis, your body will have:
- A higher metabolism
- A suppressed appetite.
- Increase in muscle mass
- Fat as a source of rich fuel
- Better mental clarity
