Ketosis for those of you who don’t already know is essentially your body running on fat for fuel instead of glucose. This type of ‘fat fuel’ is known as ketones and has proven to be a much cleaner fuel source compared to glucose.
When you are making the decision of switching your fuel source from sugar-based to fat-based your body will need time to adjust.
This article will inform you on which factors will affect the length of time it takes for you to enter ketosis.
Quick Over-View of the Ketogenic Diet:
The Keto Diet is a diet that is growing huge following in today’s society – and rightfully so!
As you can tell from this website we are huge fans or its benefits particularly in how it can treat adults and children on the Autism Spectrum.
I have written an article on ‘how a ketogenic diet can help with autism’ if you would like to learn more. 🙂
It basically is a cousin of fasting, as the two achieve similar goals in how it can benefit the body. Both we will cover in today’s article so keep reading if you want to find out more.
How to enter ketosis:
The only ways you can benefit from ketosis is to enter ketosis. You can enter ketosis by dramatically lowering your carb intake; this can be done in 1 of 2 ways:
- Through fasting i.e. not eating for a length of time.
- Through eating low carb.
This is generally the quickest way for people to enter ketosis however it is the trickier of the two as it requires abstaining from food entirely.
Most people shy away from fasting as a means of entering ketosis as they are afraid of starving themselves. Fortunately, I’m here to tell you that this couldn’t be further from the truth.
If you watch Dr. Fung’s YouTube videos he goes into superb detail on the difference between lowering caloric intake and fasting. Incredibly it is in the lowering of calories that causes starvation-mode in the body.
The body, determined to keep homeostasis, will continue to lower your Basal Metabolic Rate (BMR) when you cut calories which leads to lack of energy, drop in body temperature etc. THIS is starvation mode.
Fasting on the other hand does not do this at all and amazingly it has been proven that your BMR actually increases by the 4th or 5th day of a prolonged fast.
So how long does it take for your body to enter ketosis when fasting?
It usually takes your body at least 12 hours before your body has burnt up all its sugar and glycogen stores in the liver. If you are already fat-adapted i.e. your body is used to burning fat for energy (maybe you do fasts on a regular basis) you can probably activate ketosis faster than a non-adapted person. Some people who have insulin-resistance might need longer for their bodies to eventually kick into ketosis.
If you’ve decided that maybe fasting isn’t for you right now don’t despair!
There is another method of achieving ketosis without having to eat nothing for a few days and that is through eating low carb.
There are lots of low-carb diets out there but none quite like Keto.
The Ketogenic Diet, as I have said before, is a cousin of fasting, so it will give you all the benefits that fasting does for you. The reason why I would recommend Keto over fasting would be because fasting is something you can’t do long term ( you can’t fast for the rest of your life I mean) but with keto you can.
There are loads of yummy keto foods out there that make choosing keto a very easy thing to do. However, with keto it will take a little longer for your body to kick in to ketosis – but once your in ketosis your there for as long as you continue your keto journey.
If you want to get started on your ketosis journey here is a 28 day program that can help you lose weight, gain energy and can help you feel amazing.
So how long does it take for your body to enter ketosis when eating low-carb?
It usually takes around 1-2 weeks of eating keto ( 75% fat, 20% protein, 5% carb) to properly enter ketosis.
This is due to the fact that while fasting, you are eating NO CARBS – because you’re eating nothing at all! Whereas eating low carb, as the name indicated you are eating A SMALL AMOUNT OF CARBS.
Entering ketosis is going to do your body wonders for those of you who don’t know it yet! I am super excited for you guys, whether you are choosing to do fasting or eat low carb both are fantastic for getting your body and your health in the best shape of you life.
