I've been researching a lot on Ketosis and the Ketogenic diet and I have found out a ton of facts I didn't know.
I have also found out about carb ups, now I know right off the bat some people might think "just an excuse to cheat" or "it will slow down my weight loss" but I have read over and over again that carb ups are be helpful in some occasions.

Refill leptin levels which are crucial for contineous fat-loss, stabilize to normal T4-T3 conversion, which make the thyroid work at the normal and not lazy phase.
The metabolic rate drastically slows down if there is no carb up once in a while. Thus, fat-loss will discontinue after a certain amount of time.
Genetics and your body works goes into play here. I'm 18 years old, but it is still hard for me to lose fat. I do want to start crossfit, hiking, and 10 mile longboard ride again. I won't do a carb up for a long while because I do not have much to lose, but for people who have 100+lbs, this might be something to look into!

I've started cycling through the phases for just this reason. Phase 3 starts the process of increasing carbs. I've discussed it on a variety of threads.

When you read Dr Chanh Tran Tien's book (I have the older ebook and the new hardcopy) you see he talks mostly about short-term weight losses...not bigger losses like I'm working on. In the short-term (20-30 lb losses), you add carbs before the body starts reacting strongly to the carb restriction. My thyroid levels started showing the stress by November (testing was in December). I had started in August.

There are MANY places to find info on ketogenic diets and thyroid
Some of my favorites include Dr Cate Shanahan,
Paul Jaminet (PerfectHealthDiet.com)
Chris Kesser
Lyle McDonald briefly discusses it in his book (and cycling onto more carbs) but doesn't explain the science like some of the other folks do.
Another great website I've just started reading is called outsmartdisease.com

I've never seen any research to indicate this is true. The body can only slow down the metabolism so much.

A "Carb Up" might benefit a dieter for a number of reasons but continued fat loss isn't one of them.

Sluggish thyroid can cause slower metabolism
Thyroid is a "responsible party" for metabolism regulation

This article is really cool!

I'm not disputing that metabolic slow down happens. I'm only suggesting that the research I've looked at says it is 10-15% maximum. While this is not insignificant it is hardly drastic and certainly it cannot stop fat loss from occuring.

Interesting info Grazi - thank you so much.

I know I have been poking along in my losses lately and it's nice to think about options available to switch things up.

My personal trainer lady with 14% body fat just today suggested how to deal with stalls. She mentioned tricking the body at times and changing things up either with different exercise or nutritional patterns can prompt changes. So, your info comes in Divine Timing.

I've always suspected a slow thyroid but never went for testing. How do they do it? If blood testing, I'm out.

Thank you.

Ketogenic dieting long term can have some negative health consequences, especially in women. No argument there.

I was only disputing the fat loss halting.

You don't lve in a woman's body!

I unfortunately, learned this the hard way...

so, what are the long term consequences of a ketogenic diet, and how long could a person be on a ketogenic diet before these negative consequences are incurred? I cannot find a solid answer from my research, and when I began this diet I questioned my coach about this very question and was not given any negative response. The response I was given centered around the health benefits of giving the pancreas a rest. I am particularly interested because I have a long way to go!

Well I read online that a lady was in this diet for 2 years and suddenly developed a rare lover disease that killed her

Liver, sorry about that

Spent 52 weeks on it...monitored by my doctor with blood tests every three months. She was not my coach so I specifically reviewed EVERYTHING I was doing with her and specially said ketogenic diet. She was not concerned for my health and was excited for me and my success. In fact, we had a discussion about how ketogenic diets help epilepsy patients.

The comments on this board concerned me too (although perhaps valid in other people's health concerns due to their own personal physiological makeup, obviously with her approval and monitoring not a concern for me) which is why I had a discussion with her. Her, my doctor kept my health monitored and continually told me I was doing the right thing and everything was fine. If you are concerned, I encourage you to see your doctor. If only to tell the people off line who express concerns "I'm monitored by my health care provider, thanks".

Ishbel,

As I read through the threads, I always hear a lot of wisdom in your posts. Thank you.

Lexi -- I like the sound of rare lover disease more than liver disease! It brought a smile to my face!
