Keto Questions: How Long Does It Take to Go Into Ketosis?

How Long Does It Take to Go Into Ketosis?

So, you’ve decided to try the ketogenic diet and are wondering exactly “how long does it take to go into ketosis”?

In a nutshell – it takes a few days if you strictly adhere to a ketogenic diet meal plan. If you deviate and eat sugary foods, high carb snacks or get your macros off, you’ll likely not hit ketosis – ever.

Our bodies are said to enter ketosis at the point when blood sugar levels are low and liver glycogen are no longer available to produce glucose as a fuel for cellular energy production. At this point, not only is the body doing the natural thing, and burning off fat, it’s also powering up the brain with a super efficient fuel.

Making changes to your diet, regardless of ketosis, are a step in the right direction.

To achieve ketosis, you’ll want to have a ketogenic diet plan and adhere to it strictly. I recommend following the keto IN FIVE plan for the first 30 days.

And, to confirm you are actually in ketosis, and not just following a diet fad, you can pick up some ketone strips, a blood glucose monitor or a ketone breatholizer to test your ketone levels efficiently.

Why Try the Ketogenic Diet?

Why in the hell do you want to be on a ketogenic diet since it’s so different than how you’ve been eating in the past?

Why do you want to give up Cheetos, cheesy popcorn, corn dogs or chocolate pie for dessert?

Because, take a look at your waist line.

Take a look at your cholesterol levels, your pre-diabetes determination… yeah, that’s why.

Your body and your brain are a wreck.

You don’t sleep well at night… and you can’t fit into the clothes you wore when you were 20 or 30.

There’s a reason why you are out of shape and experiencing brain and body fatigue and unlimited levels of frustration.


Your Body is Not Burning Fat Properly

Each meal is going in (finding a home in your fat cells) and not coming out.

Extremely high levels of sugars in food are making your insulin levels spike all day… basically, your chemical make-up at the molecular level is a disaster.

The keto diet may be tough for some people to start, but it can have a positive effect on your body and your brain for the long term.


The Benefits of the Keto Diet

Instead of writing down all the positives of the keto diet, I’m just going to quote a lot of studies. Why re-write everything when the researchers have so eloquently explained everything?

The classic ketogenic diet is a high-fat diet developed in the 1920s to mimic the biochemical changes associated with periods of limited food availability (Kossoff, 2004). The diet is composed of 80–90% fat, with carbohydrate and protein constituting the remainder of the intake. The diet provides sufficient protein for growth, but insufficient amounts of carbohydrates for the body’s metabolic needs. Energy is largely derived from the utilization of body fat and by fat delivered in the diet. These fats are converted to the ketone bodies β-hydroxybutyrate, acetoacetate, and acetone, which represent an alternative energy source to glucose. –

Ketone bodies, including β-hydroxybutyrate, that are produced during consumption of the ketogenic diet may serve as an alternative source of energy in states of metabolic stress, thus contributing to the neuroprotective activity of the diet. In fact, β-hydroxybutyrate may provide a more efficient source of energy for brain per unit oxygen than glucose (Veech et al., 2001). –

The ketogenic diet may also protect against various forms of cell death. –

It has long been recognized that the ketogenic diet is associated with increased circulating levels of ketone bodies, which represent a more efficient fuel in the brain, and there may also be increased numbers of brain mitochondria. It is plausible that the enhanced energy production capacity resulting from these effects would confer neurons with greater ability to resist metabolic challenges. Additionally, biochemical changes induced by the diet – including the ketosis, high serum fat levels, and low serum glucose levels – could contribute to protection against neuronal death by apoptosis and necrosis through a multitude of additional mechanisms, including antioxidant and antiinflammatory actions. –


Final Thoughts:

Being in ketosis can have drastically positive benefits to your body, brain and mood. But, before you start a new diet to help reverse the negatives of a high carb, high sugar diet, be sure to consult with your doctor or nutritionist.

Drastically altering your diet shouldn’t be taken lightly, yet making changes to eliminate sugars and carbs are a positive step in the right direction regardless of achieving ketosis.

I started this website because I love the ketogenic diet and intermittent fasting lifestyle. My favorite way of eating is to eliminate as many carbs as possible from my diet, eat lots of greens, and real food, forego anything that comes in boxes or is manufactured or produced in a factory or made from chemicals that mean absolutely nothing to the average person. I’m recommending products in this article that have affiliate links and will pay me a small commission if you purchase something to help you along with your keto diet. I always recommend products I think will be beneficial, based on other people’s reviews of the products or my personal research on the efficacy of the product, for your ketogenic diet journey.
