Unintentional Ketosis

Answered on September 12, 2014
Created July 30, 2013 at 9:20 AM

I've been paleo for about 7 months but recently cut out fruit (except berries) because I don't feel like it anymore.

Since that time, even though I have around 60g carbs a day on average including a small baked potato for lunch, I often have that metallic taste in my mouth, and am pretty sure I'm often in ketosis.

Is this even possible? I thought you had to eat under 50g carbs to go into ketosis? (per Sisson). I'm reasonably fit and am a healthy weight (161cm, 59.5kg female).

Sustained Fitness - Definitely not intense. I do 4 gym sessions a week. 2 are weight training, 2 are sprints.

I use a blood ketone meter to test ketosis. I don't do ketosis normally, this is just an experiment -- but the only way to know for sure is via blood levels. They are cheap (~$25), the test strips can be expensive if you are doing multiple per day

Yes you can and will go into ketosis if you are carb AND glycogen depleted due to intense exercise.

Yeah my fruit intake has gone down and my fat intake went up (not necessarily by coconut oil though...mainly butter).

Yeah I'm fairly active also, so maybe this is a factor. It would be interesting if someone like Sisson did an article on the different factors that can cause ketosis at different levels of carbs. I'd be interested to find out.

"Staying in ketosis for too long can cause ketoacidosis, which results in damage of the kidneys and liver." That is completely untrue. First of all, ketoacidosis only occurs in type 1 diabetics. Second, once the body achieves ketoadaptation, you can stay in ketosis indefinitely without doing damage to the body. There are cultures around the world that eat virtually zero carbs for the majority of the lives and are extremely healthy.

also, MCTs can induce ketosis. So if you recently started doing a coconut or MCT introduction that might also contribute.

You most certainly can go into ketosis with 50g of carbs, easily! It will be different for everyone, but I work out a lot too and I can go many days with well over 100g and stay in keto. I actually sometimes have to eat additional sweet potatoes and other high carb veggies just because I go into heavy keto.

Also if you work out on a very consistent basis then you could go a day-a few days eating 50g+ of carbs and still stay in keto without doing any cardio or weight training at all! Some peoples bodies recognize what is going on and will actually adapt to maintain a keto fueled lifestyle.

There are lots of ways to induce ketosis. I have been working on a high carb ketosis experiment for 6 weeks now. I have found that I can stay in ketosis (>= .75 mmol/L although usually my measurements are above 1.5) while consuming up to 90g carbs. So long as fewer than 25g come from sugary carbs and I consume 0g alcohol.

The trick for my experiment is that I am reducing my fat intake and focusing on consuming high protein and maintaining a slight caloric deficit (as best as I can manage). It is a variant of the PSMF.

So certainly you can be in ketosis while at 60g of carbs. Especially if you removed the sugary carbs you were previously consuming.

Whether you are in ketosis or not is unclear.

I'm pretty sure that I accidentally went into ketosis a few times on even higher carbs than that (around 100-150g). I am really active and do sprint workouts and 5+ mile runs fairly regularly so I wonder if you can go into ketosis if you burn all the carbs through exercise. Great question... I had been wondering the same thing!

Same thing happened to me, so I guess you can. Everyone has different needs for carb intake; Sisson's carb curve is just a guideline, it's not strictly true for everyone. So if you don't feed your body enough carbs, you will go into ketosis whether you want it or not.

If you're not trying to lose weight, I recommend you eat more carbs. Staying in ketosis for too long can cause ketoacidosis, which results in damage of the kidneys and liver.

If you dont feel like eating fruit, you can get your carbs from organic nut butters, sweet potatoes, tapioca, plantains, pumpkin, beets, cooked carrots, and even some white rice every once in a while. Try plantain pancakes, tapioca crepes, or almond-carrot cupcakes! All the recipes are online, and they're an awesome way to add carbs to your diet.

Much love(:
