“Is it safe to stay in ketosis indefinitely?”

askdrandreaseenfeld

Is it harmful at all to stay in ketosis forever? Why is the scale not moving even though on the meal plan? And what about age and weight loss?

Get the answers in this week’s Q&A with Dr. Andreas Eenfeldt:

Can we stay in ketosis indefinitely?

I was watching the documentary, ‘The Skinny on Fat”, and one of the doctors said it’s not good to stay in ketosis indefinitely. Is this true? Or did I misunderstand?

There is no proof that it’s anything but healthy long term. However, most people end up dipping in and out of ketosis semi-regularly anyway, as it’s a hard thing to ALWAYS be in deep ketosis. So if being in ketosis forever has any negative unknown effects, it’s likely something that very few people are going to experience anyway.

Why am I not losing??

I am so confused! I am eating to the meal plans provided and I have not lost a thing. I know my body has changed as the pictures I take show it, but the scales are not moving and if they do it is up not down. I am so lost! Help!

Hi Leigha,

If your body is changing that’s a good sign! I would suggest first making sure you’re really keeping your carbs very low, second make sure you’re not eating more fat than you need to stay satisfied after meals, and third consider adding some intermittent fasting.

Here are many more tips if you want them:

Serious hair lost after 4 months on keto

Hi Dr. Andreas,
I have been loosing a lot of hair at the 4 months mark of my keto diet, which is very scary for a healthy 46 years old women. I don’t need to loose weight, my main reason to be on keto diet is to get rid of the pain in my body, as I feel that I have a lot of inflammation or I get inflammation muscles easily from activities.

Now, I have stopped the Keto diet due to the serious hair loss, even when I have been drinking bone broth together with lots of seaweeds a few times a week at least. Would you pleases let me know what I should do? I am back on my normal high-carb diet for two weeks now as I am on holiday, the hair lost seems to slow down.

If I go back to keto after 1-2 days of fasting, will I keep on losing a lot of hair again right away or it will start again after four months ?

Thank you and hope to hear your answer soon!

Hi Kamie,

Hair loss after four months is not entirely uncommon, and it’s normally a very temporary thing that you’ll completely recover from.

Does age have anything to do with a keto diet for weight loss?

I’ve been on a keto diet for 3 plus weeks and have been in low to moderate ketosis for at least 3 weeks. I have experienced the leg and toe cramps at night and have increased salt intake and have been using magnesium supplements to address the cramping issues. Although I can see less fat on my body, I have not experienced any weight loss. I have been intermittent fasting for 16-18 hrs. a day for 3 weeks. I would like to loose 40 lbs. I have listened to many of the Diet Doctors videos. I am 73 years old. Could this lack of weight loss have anything to do with my age? Any suggestions?

Hi Wanda!

Yes, weight loss can be more of a challenge with age, especially for women. It’s certainly not fair. It seems like you’re doing many things right, but perhaps you can find some useful tips here, beyond just being persistent:

    In regards to hair loss - my doctor put me on zinc tablets as I was experiencing the same issue - (it was actually occuring before I converted to LCHF, but I think I was not really paying much attention as I had other health concerns to concentrate on) although my blood markers didn't show that I was low in zinc. However, it completely fixed it. If I go off zinc for even a few weeks, my hair loss returns. I am pleased to report that all my other concerns have disappeared and all my markers are excellent. It was my own doctor who suggested I go low carb in the first place some 3 years ago, but I didn't do it in earnest until 18 months ago. That was when I found Diet Doctor, and I haven't looked back.

    I have been eating LCHF for almost a year now. Moderately, have lost 45 pounds, 15 inches off my waist, no hair loss as I take magnesium, zinc and a multi vitamin daily.
    My blood pressure dropped, my cholesterol fine and my endurance has surged. I have been sugar and gluten free for 242 days.

    Go plant based. It's far better for you and won't wreck your health long term like keto will.
  5. BobM
    Bg, there's really no evidence that "plant based" is better for you than anything else. For instance, in the Women's Health Initiative Dietary Intervention Trial, they took 49,000 women and put them into two groups. The control group ate whatever. The group under test ate less red meat (by 20%, a statistically significant amount), more fruits and vegetables, less saturated and total fat, and fewer calories. Yet, at the end of 8 years and 400+ million US dollars, there was no statistically significant differences between the two groups. And this includes cancer, which the study was specifically designed to test. (This is one of the ONLY two RCTs I know of that tested reduction in red meat and cancer, both of which indicated red meat did not cause cancer.)

    Your evidence that plant based is good for you?

    I just finished the 2 week challenge; followed it exactly. the food was great, completely satisfying and i was never hungry. BUT, I never got into ketosis! a few times the dipstick read "Trace" amounts. I do not need to lose weight. I am doing it for other health reasons. So, I am disappointed. What am I doing wrong?

    Pam,
    It may take a little longer to get rid of the carbs in ur liver. Once the carbs are depleted in ur liver, u will be good to go. Hang in there! U r almost there.

    Hello, my aunt is 79 years old and has high cholesterol and danger of some blockage in her veins. Is she a candidate for a Keto diet?

    Besides this, do you know if popcorn is permitted for snack?

    Thank you.

  9. Gentiann
    Popcorn is a high carb snack and should be avoided.
