7 Signs You Are In Ketosis

The Ketogenic Diet (also known as “keto”) has been all over social media.

You've probably seen ripped fitness models claiming that Keto gave them their physique, and the even more inspiration stories of normal people like you and me, who lost weight and reclaimed their lives through this diet called Keto.

If you're not sure what the Ketogenic Diet is, head on over to What is a Keto Diet? (Ketogenic Diet 101).  Over there I've detailed what exactly Keto is and isn't, given you meal plans, snacks, and answered all of your questions about the diet.

But let's say you've jumped into Keto with both feet, and now you want to know “Is this working?”

I don't blame you.

It can be hard to tell what's going on inside your body.

Are you in Ketosis?

Are you eating few enough carbs?

Are you shedding fat?

Well, there are 7 obvious ways to tell if you're in ketosis, without testing your blood or urine.

Here are the signs you're in Ketosis:

1. Weight Loss

Weight loss is the first and most obvious sign that you're in ketosis.

The weight loss happens for a variety of reasons, but it's important to note that it's very fast in the beginning.

This is because when you switch to a low-carb diet, your muscles start losing water.  Carbohydrates are what bind water to your muscles, so when you're not eating carbohydrates, your muscles start dumping them, and the attached water.

That's one of the things that causes Keto Flu (which you can read about in Keto 101), but drinking plenty of water and keeping your salt intake up will keep you hydrated and feeling healthy.

After the initial water leaving your body, then you'll start to see steady fat loss.

2. Little or No Appetite

When you stop eating carbs, something crazy happens:

You don't get hungry.

At least not as much or as often.

Instead, you will find that your levels of satiation from your meals require much less food because of the super high fat content.

Also, when you're in ketosis, your body does a better job of regulating the hunger hormones that make your brain tell your body it's hungry.

3. Clear Mental Focus and Energy

I love this particular perk of ketosis.

If you struggle with an afternoon crash, then ketosis could be your  miracle cure.  An afternoon crash is caused by your insulin levels plummeting – a result of your carbohydrate eating habits .  But when you're in ketosis, you don't have the crazy blood sugar rises and falls, and your brain has an endless supply of fat to fuel it.

Your mental focus and energy levels will become so much better if you're in ketosis, and it will be a noticeable difference.

4. Crushing Fatigue – Then Nothing

Hold the phone…

You mean to tell me that you can tell if you're in ketosis by if you're fatigued?

Yes.  Well, sort of….

When you cut out carbs intent on moving your body into ketosis, it takes your body a little while to catch up with what you're trying to do.  This process is called the Keto Flu.

I'm not going to lie, ti's not fun, but when the nausea, headaches, and fatigue subside, this is a good indicator that your body has crossed over into Ketosis.

If your Keto Flu symptoms aren't subsiding within a few days, this might be a good time to drastically increase your water intake and take some Exogenous Ketones.  This will help your body get into ketosis faster.  I get my MCT Oil Powder and Exogenous Ketones from Perfect Keto.

5. Digestive Upset

Everyone's digestive system reacts differently to a change in diet like cutting down on carbohydrates.  Yours could go one of these ways:

1. Constipation: You could go days without using the bathroom, but if it gets to be more than a few, please take a stool softener or add more fiber to your diet so you don't get “stopped up” for too long.
2. Diarrhea: Adding more fat to your diet can have an impact on your digestive system as well.  Your body will adapt in a bit, but if you want to keep from running to the bathroom every few minutes, try taking a fiber supplement.  (Please make sure you're drinking enough water, too!)
3. Nothing: Some people have no trouble, but I find that most do.

6. Bad Breath (Fruit Loop Breath)

Fruit loop breath is on almost unavoidable sign of Ketosis.

This stinky breath is caused by increased Ketones in your blood (a sign your keto diet is working), but there are a few things you can do:

• Brush your teeth more often
• Use mouthwash
• Chew gum
• Grin and bear it

For most people, the stinky breath goes away in a few weeks, so don't think the problem will be there forever.

7. Increased Ketones

You can actually test for ketones in your system a couple of ways:

With Urine Strips:

This sort of gross, but the biggest issue with testing your urine for ketones is that these strips, while cheap, are pretty inaccurate.

With A Glucose Meter:

This method is more expensive, but more accurate way to test for ketones, and if you're in ketosis is with a Glucose Meter.

Signs you are in ketosis can vary from person to person.

But, you'll most likely find that at least a few of these hold true for you.

In the beginning you'll lose a lot of weight, but then weight loss should level off into steady weight loss, between 1-3 pounds per week, depending on how your body responds.

You'll also have to tinker a bit with your carbohydrate levels.

Some can eat at the top of the limits (50g per day) while others eat 20g or less per day, and some even have 0 carb days.  The point is to get your carbohydrate levels to where your eating does not produce an insulin response, and leaves your body with elevated ketone levels – known as Ketosis.
