Citation please.
I am headed to the gym. It's pretty easy to find this I formation yourself of you are at the computer. I can post one of the many articles later tonight if you are too lazy to use Google.
Why should I Google? I'm a medical doctor trained in biochemistry. Like "Climate Change," I'd like to see where your getting your information from.
p.s. Not trying to be an asshole.
This blogger is one of the proponents of a keto diet and she explains a lot of the risks with links to the relevant research papers.

Adverse reactions are not the same thing as side effects. An adverse reaction is an, unwanted/unexpected and dangerous reaction to a therapeutic agent. In contrast, a side effect is a secondary, typically undesirable effect of a therapeutic agent. More simplistically, side effects are minor and adverse reactions are not. Side effects are typically what are reported in shorter-term studies, where as both side effects and adverse reactions are reported in the long-term ketogenic dietstudies (typically 6 months to 2 years, but any study that allows for keto-adaptation, which takes up to a month, can be considered long-term). This article is not a discussion regarding side effects, the list of which has some overlap with the list of adverse reactions (for example common side effects include minor gastrointestinal symptoms). This article is to draw attention to the documented adverse reactions, which include:
Gastrointestinal disturbances (diarrhea, vomiting, nausea, constipation, GER)
Inflammation risk
Thinning hair/hair loss
Kidney stones
Muscle cramps or weakness
Hypoglycemia
Low platelet count
Impaired concentration/cognition
Impaired mood
Renal tubular acidosis
Nutrient deficiency
Disordered mineral metabolism
Poor growth in children
Skeletal fracture
Osteopenia/osteoporosis
Increased bruising
Sepsis, infection, bacteria overgrowth
Pneumonia
Acute pancreatitis
Long QT intervals
Cardiomyopathy
Shift towards atherogenic lipid profiles (including hypercholesterolemia and hypertriglyceridemia)
Heart arrhythmia
Myocardial infarction,
Menstrual irregularities and amenorrhea
Death
That’s a long list. A long list of not-good things. And did you can’t that last one? Five scientific papers have reported deaths as an adverse effect from long-term ketogenic diets (here’s the citations: Stewart, et al., 2001, Kang, et al., 2004, Kang, et al., 2005, Bank, et al., 2008, Suo, et al., 2013 and make sure to check out the free PDF download of my Literature Review at the bottom of this post which contains details on all of the papers reporting adverse reactions). Two of these papers are case studies, and the other three are papers derived from two separate clinical trials, all studies in epileptic children. Some of the deaths can be attributed to extra complications from secondary conditions or accidents that befell the child during the course of the clinical trial; however, other deaths—most typically from severe infection or heart disease—are attributed directly to long-term ketosis.
It's a matter of weighing the risks and rewards. If you are an epileptic, diabetic, or you are obese, then sure, the risks of those adverse reactions to ketosis are worth taking. I mean.. you could die from those conditions too so you have to do something.
Then, lots of people can roll those dice and not experience the adverse reactions, but according to most of the research, the reason most participants drop out of trials is because of those adverse reactions. For every success anecdote, you can find a horror story.
Also, I suspect the average bloke doing this longterm is not in ketosis all the time. He's cycling in and out of it, maintaining it for a week or so until his will finally collapses and he eats a bag of chips. But every time you go through the process of going into ketosis, there is a short window in which your body begins to break down muscle to produce glucose to fuel your brain. Eventually it decides to switch to fat, and that's when you enter ketosis. But, holy fuck man, if you are cycling in and out of ketosis all the time, what is that doing to your muscles?? I am not sure I would want to fuck with that.
^^^ That should be the biggest concern for the dudes in this thread playing with this diet.
Then there is the performance issue. Your body performs best at lots of sports and activities by burning carbs. If you want to be a marathon runner or something, then fine, become a fat-burner. But if you want to do things like martial arts, gymnastics, weight lifting, sprinting, football, etc.. then wouldn't you rather perform better? What's the fucking point of a diet that makes you perform like shit at the activities you love most?
And muscle loss. How about: no.
If you really want to figure out how to lose weight, then you might want to listen to the natural body builders. Yeah, they compete in a beauty contest, but they have figured out over time how to cut enormous fat off the body with minimal muscle wasting. Many of them use ketosis, but short-term. Carb-cycling makes sense to me, and it's what I do naturally without even thinking about it.
The average guy who is not fat could do just fine by sticking with intermittent fasting (with fasted cardio about three or four days per week) and keeping track of his macros. On days he did his fasted cardio, he can probably get away with higher carbs to replenish his glycogen stores. On other days, drop the carbs and increase the fat a bit to keep your hormones balanced.
I would worry about the
kinds of carbs rather than just carbs. Carbs like sugars and alcohol will ruin you. Breads a little bit worse. Veggies and fruit are relatively good. For slow-burning carbs that help you in the gym and keep you full most of the day: oats and rice.
