Has there been any more research into the long term health effects of Keto? I tried it years ago, but found it to be more of a pain than it's worth (I seem to have better luck with intense exercise 3x per week and avoiding sugar). And it seems like tons of meat and cheese is actually bad long term, in the sense it clogs your arteries or increases cancer risk. Atkins did not look like he was in good shape inside when…

Some epileptics do keto long term, so I imagine there must be information out there. Rather than searching for it in the context of weightloss, searching in the context of epilepsy might give better and more studied results.

For a nudge in that direction, here's info from my doctor's charity:

The digestibility of the carbs in sweet potatoes is highly dependent on the way they're cooked. Boiling them leads to a fairly low glycemic index and glycemic load, whereas baking them essentially turns them into candy: http://www.livestrong.com/article/295025-the-glycemic-index-...

It is also possible to reduce the glycemic index of food by ingesting acetic acid (apple vinegar). See: http://www.jbc.org/content/135/1/157.full.pdf TL;DR Apple cider vinegar will decrease the glycemic index of food by interfering with carbohydrate digestion.

Acetic acid is vinegar, not apple cider vinegar in particular.

He said eat normal and healthy, not eat low fat; low fat is also a fad diet. And yes, keto is a fad diet with no empirical evidence to support its claims, testimonials are not evidence. There was actually a recent scientific study done and it found keto claims lacking. I've done keto, I'm well aware of what it is, but the weight loss is far more likely to come from eating less than from not eating carbs because it's…

You're also neglecting another benefit of keto for maintaining a low-caloric intake, it encourages you to eat fat . Fat takes a substantially longer amount of time for the stomach to process, meaning you feel satiated for a longer period of time. Whenever I eat carbs I try to supplement them with a good amount of fat to avoid this, yesterday I had a 300cal snack of 5 saltines topped with roughly 3tbsp of peanut butte…

Normal and healthy diets are balanced; most people's diets are excessively heavy in carbs, so no, I didn't neglect that at all. People should eat less carbs and more fat until they're somewhat of a balance, going in either direction by cutting out one or the other is not eating healthy. Keeping your body in long term ketosis is neither healthy nor particularly pleasant. Yea, eating a pure carb snack is going to make you crash, so don't do that, eat something balanced and made of real whole food, not processed crap.

Fat takes a long time to digest in your stomach, as such you feel satiated for a much longer period of time. Butter can be used somewhat to sweeten coffee, and unlike using sugar won't invoke an insulin response and a subsequent crash.

Might as well use heavy cream. 20% or more, just an unsweetened version. Pity the diet trashed my liver long term. Not sure why (the actual dietetician had no idea either), but lab numbers do not lie. (Aspartate, alanine, cholesterol, no inflammation in CRP) It was the only thing effective so far. Long term was around 2 years thereof. Moral is, diet responsibly and pay for the metabolic panels when dieting.

What exactly did it do to your liver (what's the diagnosis so to speak), did you have alcohol, what carbs did you have, and how do you treat the issue now?

This has been scattered around the existing comments, but I'd be really interested to hear people who are keto comment explicitly on its perceived cognitive effects. I know a number of pretty successful scientists who have told me they feel that being keto provides them a significant performance advantage. I'm really interested in how it affects perceived energy, clarity of thinking, fatigue, and creativity. I'm gear…

I went through about 2 months of pure keto earlier this year. Small disclaimer, I generally follow a "warrior" diet and intermittent fasting. I think keto gave me a similar "sharp" awareness and energy. For whatever reason, not eating, while difficult at first, provided me with even more energy and clarity in the same way keto did. Even though I continued doing fairly intense workouts 3 days a week.

I also get a lot of mental clarity and alertness after extended periods of not eating, followed by tiredness and fogginess after a meal. This might be one reason why I'm underweight.

Unfortunately, a keto diet isn't really an option for me (vegetarian, and allergic to many vegetarian protein sources).

I wonder what the underlying science behind it is.

I appear to be one of those weirdos who reacts to something in bread but not celiac. I was watching that Michael Pollan series and he was talking about his theory that industrial bread was the problem and everyone would be fine if we went back to sourdough. Well this feels like one of those things that sounds good but has no substance, but clearly at this point I'm willing to try anything. There's a little bakery on…

Most bakeries use commercial yeast in addition to starter in what they call sourdough. If you haven't already been doing this, you need to ask if there's commercial yeast in their sourdough. You might need to shop around to find a bakery that does it pure. My partner has a similar condition (not celiac, not gluten sensitive, but 'something in bread' sensitive) and she found that sourdough from locally made starter wa…

It's hard to not start a starter with yeast and can be dangerous to not use a commercial yeast to keep a starter going. If the conditions are not right or it's not a safe yeast colonizing your starter it can be deadly.

I don't have a strong opinion about the origin of the starter. It will definitely influence the flavor of the bread but other than that I don't think the origin is important. More important is the rise times. A longer rise is more likely to convert more sugars and also more likely to give indicators of a bad batch.

During my faste days, wherein my caloric intake drops down to the two-hundreds I have experienced significant improvements in cognition. Specifically my awareness of my surroundings, ability to concentrate for long periods of time and short term memory recall improved noticeably. The first time it happened to me during one of my faste days it felt as though I had taken a powerful stimulant.

I've never tried keto, but I also get a lot of mental clarity and alertness after extended periods of not eating. It doesn't seem to make a lot of evolutionary sense.

I've been doing Keto since Feb 25 2016. My primary goal when switching over was weight loss, which turned out to be easy. I'm 25, male and was experiencing growing health complications related to obesity. I've lost well over 60 lbs since making the switch despite the fact that I maintain a primarily sedentary lifestyle though I now work out weekly as well as take bi-daily walks. There are downsides though. It's not c…

My biggest problem with keto was issues with getting enough potassium. There's no easy way to supplement it in the US, unless you get a prescription for supplements. I tried using No Salt, but I hate the taste. Lite Salt was tolerable, but I'd end up exceeding my recommended amount of daily sodium.

>And it seems like tons of meat and cheese is actually bad long term, in the sense it clogs your arteries This is an inaccurate conclusion based on old studies where the subjects underwent a high-carbohydrate high-fat diet. Recent studies on ketogenic diets (low-carbohydrate, medium-protein, high-fat intake) shows that dietary fats and dietary cholesterol barely make any sort of impact on the subject's cholesterol. R…

What you said about cancer risk or long term safety of the whole class of those diets. Especially anything related to mortality and morbidity endpoints.

Cholesterol numbers are nowhere near the end of story, they're just markers. Rat and mice studies are useless for this purpose.

Please correct me if I am wrong. Preferably with published larger studies. In humans.

Check out Keto Chow. https://www.thebairs.net/ I have no affiliation with them and don't drink it often but I can tell you that it tastes awesome.

tried it, tastes like garbage in my opinion. tried like 3 flavors

wow. it is literally one of the most delicious things I've ever consumed. Interesting how significantly tastes can differ.
