One thing. Paleo has nothing to do with Ketosis. While meat and vegetables are encouraged and are the basis of the paleo food pyramid, carbs like from sweet potatos, honey, vegetables with higher amount of carbs and nuts are considered paleo. You can argue about what is paleo and what not, but carbs are considered totaly fine as long as they come from a good source. So if you did paleo and ended up in ketosis you pro…

I think your comment it accurate. As I mentioned doing paleo multiple times before I never reached ketosis. Cheat meals on the weekend aside, I also included sweet potatoe (after runs), honey and nuts (almonds, cashews). This last time around, where I experienced the change (I believe ketosis) I can basically say my diet consisted of: eggs, chicken (mostly dark meat), red meat, green leafy vegetables, and sometimes p…

I guess you can also look at ketosis as a state. Maybe paleo diet even gets you from time to time into ketosis without really intending to do so.

What I also wanted to say is that you can find sources for carbs in the paleo diet... especially if you do sports (and you did it actually as you mentioned)

This is freaking genius. Kudos. I wish I could upvote this 1000x.

Sorry for the crosspost/copy-and-paste:

For me personally this worked quite well for reducing bodyfat:

Intermitted fasting[1] and lifting weights 3 times a week[2] and being on a cutting regime[3] (cutting on the rest days with low carb and loading on the workout days wiht more carbs).

In the beginning IF was quite difficult but after a while the body get used to it and also I tend to have less cravings during the day. On the loading days/workout days I often have a hard time to get enoug calories because I feel full. I am using MyFitnessPal to track what I eat but it's more about the macros and not so much about the exact calories (but it's also good to get a feeling how much calories different kinds of food has)

One thing I've never been able to get a clear answer on, is when you "lose" fat, how long does it take for the number of fat cells to go down? As I understand it, at first fat cells just deflate (not the right word) are will easily plump up again and that's one reason why it's hard to keep weight off. What's involved in actually ridding the body of the extra cells (outside of mechanical means)?

Warning: unpopular opinion here. Long term low carb dieting and ketosis is not without risk. Yes, you will see weight loss, but what about other health markers? Check out some of the information here: http://nutritionfacts.org/topics/low-carb-diets/ What has worked for me was a plant based diet without added oil and processed foods: https://medium.com/@borkdude/tl-dr-of-my-long-term-weight-lo... Been doing that for five years now. Never hungry, still happy with it.

> As a backup mechanism your liver can also produce glucose by converting amino acids (muscle) and even fat, a process known as gluconeogenesis.

Just a quick note, and your explanation is fantastic otherwise: this isn't quite correct. The (human) liver doesn't use fat directly for gluconeogenesis. It's just not efficient for humans: We wouldn't gain enough energy from it. The liver uses fat indirectly through glycerol (which is a product of fatty acid catabolism), but it's important to draw a distinction here because this is why ketosis occurs - if the liver could efficiently break down fat directly, ketosis would never happen at all! Most tissues would much rather use glucose directly if it's an option.

While muscle breakdown occurs in small amounts normally it's mostly a last resort that occurs after an extended period of starvation. Which makes sense: You wouldn't want to break down the thing (skeletal muscle) you need to get more food except as a last resort. The amino acids involved in more typical gluconeogenesis largely come from other sources.

How does blunted insulin response feel? Is that as simple as feeling burnt out early?

Can you give a short overview of what you are eating and why? Just plants? Also including nuts? What about eggs? If you go full vegan it's not without risk either, you know.

There is an often-forgot other situation where your body needs some stored energy: sickness and accidents.

Does it really need stored energy? Parenteral nutrition in hospital works fine with plain glucose. One would assume you could just eat fruit (or drink soda, I guess) when sick, to get the energy you need right then.

Yes, your body can't carry that much energy in your blood - it gets shunted off to glycogen or fat quickly because if it didn't the chemistry would start to go horribly wrong.

You could maybe do what you suggest by just slowly sipping a glucose solution over the course of a few hours but it would be very inefficient.

I don't have a weight problem, I learned about ketosis researching natural ways for improving focus and concentration, and somehow came across "bulletproof coffee".

"Bulletproof Coffee"(TM) is snake oil stuff. It's based on the assumption that all other coffee on the market has mycotoxins, yet literally none of the brands in first world countries have them anyway. This was confirmed by tests.
