How Do I Know If I’m in Ketosis?

For those of you looking to lose weight and get in shape, you might think that dieting sucks. But it doesn’t have to!

To be honest, it all depends on what type of diet you follow. If you’re on a dangerously low calorie diet which is virtually fat free, then of course you’ll feel awful and will wonder why you’re torturing yourself just to lose a few measly pounds. If however, you were able to find a diet which allowed you to be very generous with your calories, and to consume foods like steak, whole eggs, cream, salmon, and even bacon (in moderation) things wouldn’t seem so bad. With keto diets, that is exactly what you get, as they allow people to consume high amounts of healthy fats, and moderate amounts of protein, whilst keeping carbohydrate consumption low.

As we’ve said before on the Ketoship blog, the idea is that you force your body into ketosis, where it basically burns fat for fuel, rather than glucose. Generally it takes around 3 – 5 days to enter ketosis, but how do you know when you’re in ketosis? Well, here are some signs to look for.

Bad Breath

Though not a particularly pleasant side effect, those of you following a ketogenic diet should be pretty happy if your breath begins to smell, and you get a bad taste in your mouth. This is because ketosis causes bad breath, due to the fact that the excess ketones in your body contain acetone, which is expelled from the body in urine, and via the breath.


Fat Loss

When looking for signs that you may be in ketosis, fat loss is perhaps the most welcome of all. If you find that you’ve lost weight in a relatively short amount of time, you could very well be in ketosis. When in ketosis, the body burns fat for energy, rather than glucose. In the early stages, it will burn a fairly high amount of fat in a short space of time.

It is not uncommon to lose around 7 pounds per week on keto, for the first couple of weeks. Weight loss will eventually slow down and you may need to overcome a stall in your weight loss, but if you’ve lost weight and have stuck to the diet plan, this is a clear indication you are in keto.

Suppressed Appetite

Another thing to look for when trying to enter a ketogenic state, is a suppressed appetite. Ketosis has been found to suppress a person’s appetite, so you’ll be less hungry, and will feel full for longer. Frustratingly, we don’t know exactly why this is, though experts believe that it’s down to alterations to hormones and receptors in the body responsible for hunger, plus the increase in protein, which is thermogenic, so it is harder for the body to digest.

Increase in Energy Levels

When you begin making the transition over to ketosis, for the first few days you may well feel awful (something known as keto flu). This is because your body will have virtually no energy due to a lack of carbs, but it will not yet be in ketosis and so it can’t yet utilize your body fat reserves. You will feel tired, your head will hurt, you’ll have no energy, and all you’ll want to do is sleep. When you enter ketosis however, you will wake up full of life and vigour, and will have heaps of energy. When you wake up feeling this way, you will almost certainly be in ketosis.
