How does keto work?

The keto diet has become very popular in recent years, with celebrities such as Halle Berry and Jenna Jameson (among many others) swearing by it. The keto diet is a high-fat, low-carb diet and is really what we can maybe consider an upgrade or supercharged version of previous low-carb diets. It has been shown to be a very effective method to lose weight and can also improve overall health. So how does keto work?

The standard American and Western diet has, for a long time, been high in carbohydrates, with saturated fats considered the foods to avoid. However, we now know that refined carbs such as white bread have their own issues. When you eat a meal high in carbs, these are converted into glucose, which your body uses as its standard fuel.

How the keto diet works is to switch your body’s main fuel source from glucose to fats. Since the keto diet involves eating low-carb foods, the glucose becomes unavailable as fuel, and when your reserves have been used up, the body and brain must find another source of fuel. Your liver begins to take fatty acids and converts them into ketones, which become the new fuel. The state where your liver is producing increased amounts of ketones is called “ketosis”.

The most obvious result of this is fat loss, which is why many refer to your body being a “fat-burning machine” while in ketosis, and weight loss can happen quickly. Some go on to stay on a keto-style diet for many years.

Just a few of the benefits of ketosis and the keto diet are:

- Feeling more full, and not needing to eat as many stacks, even while eating less calories than before.
- Weight loss – specifically fat loss rather than losing muscle mass.
- Higher overall energy and less fatigue, better sleep.

It is always advisable to check with your doctor before starting on a new diet like keto, since it makes big changes in the way your body works, but it is worth doing this because of the string of benefits and weight loss.

How long does it take keto to work?

If you are wondering how long it takes for the keto diet to work, and how long ketosis takes to kick in, you’re not alone. It is one of the most common questions we have received about the keto diet. It only takes about 1-3 days for ketosis to kick in, which means that your body has begun using fat and ketones instead of sugar as its fuel source – this is because you have cut out carbs and sugars, while increasing your intake of fats, such as eggs, meat, nuts, butter, olive oil, coconut oils etc. What does it mean to reach ketosis? In the first couple of days, your body and brain will work through the stored glucose reserves - when these have been used up, your body enters the state of ketosis, which means your liver increases the rate at which it produces ketones from fat, both from the foods you have eaten and from your own body fat, hence the weight loss that is seen with this method of dieting. The reason your liver increases ketone production is simply because it is a n...

How to know keto is working

If you are seeking to lose weight quickly, you might be in search of a diet tailored to that need. Once you begin to delve into the wide array of diet ideas out there, you are likely to find many options. One such option that has gained a lot of traction in the diet world is the keto (ketogenic) diet. What is the keto diet? This diet is based on the principle of ketogenesis which is the idea that the body gets the bulk of its energy from proteins and fats when they are converted by the liver into fatty acids and ketone bodies. Therefore this diet dictates that consumption of foods high in fat and protein (meats, poultry, cheeses, eggs, nuts, seeds, dark chocolate, unsweetened coffee/tea, low carb vegetables, and butter based products) is best for more efficiently converting food to energy, rather than intaking carbohydrates which break down and stored by the body.
