Why Some People Find The 'Keto Diet' Simply Unbearable (And Totally Not Worth It)

For me, it was a lot worse than just feeling hungry.

I've been on a diet since I was a teenager.

Sometimes, it's the latest and trendiest — like the keto diet I tried recently, or maybe Atkins or Paleo or Slim Fast or South Beach Diet I tried in the past.

Other times, it's been something of my own devising, like the summer I subsisted on little more than Diet Coke and Granny Smith apples (which I do not recommend).

Each time I've kept thinking that if I could just shed a few pounds, I'd feel so much better — not only in my clothes, but in my soul.

But when trying to eat according to a ketogenic meal plan, I quickly learned that I was not going to feel better on this diet (and ended it fast enough to avoid a full-blown "keto flu").

The keto diet side effects I experienced were bad, especially the keto-related irritability — which isn't talked about enough.

Think of keto as a ramped-up version of the high-protein, low-carb Atkins Diet. The idea is that by starving your body of carbohydrates, you go into a metabolic state known as "ketosis," where your body starts to burn fat instead of the sugar it usually gets from carbs.

According to one popular keto diet website, that means eating less than 50 net grams of carbs a day (though 20 to 30 net grams is considered deal). This is equivalent to eating one medium apple per day.

Ketosis, as defined by WebMD, "is a normal metabolic process, something your body does to keep working. When it doesn't have enough carbohydrates from food for your cells to burn for energy, it burns fat instead. As part of this process, it makes ketones.

"If you're healthy and eating a balanced diet, your body controls how much fat it burns, and you don't normally make or use ketones. But when you cut way back on your calories or carbs, your body will switch to ketosis for energy."

On the keto diet, I was hungry all the time. But like so many other women, I thought it would be worth it.

I felt sure that if I lost a bit of weight, I'd swan around without a care in the world, nary a self-conscious thought. I'd ooze newfound confidence, self-esteem and charisma. I'd be a funnier, prettier version of myself. For the first time ever, I'd wear skinny jeans and shorts that are actually short!

This thinking was nonsense, of course, yet that didn't stop me from dreaming skinny dreams.

In this respect, I'm not at all unique.

It's said that half of all American women are on a diet at any given time, and many of us are perennial dieters. Deprivation is the mainstay of our existence, from the time we have our first period to the time we have our last — and maybe even after.

It is the language in which we are fluent, the creed to which we are devout.

We may lapse, but we get back on the wagon time and time again, never relinquishing our faith that a better, thinner existence is waiting for us on the other side.

I know that I am more than the size of my jeans.

I should know better than to let a billion-dollar industry poke holes in my self-esteem. I should just eat and drink and be merry, because I am not at all merry when I am on a diet.

And I was certainly not merry when side effects of the ketogenic diet kicked in.

In general, entering ketosis is safe. However, WebMD cautions that high levels of ketones in the body can lead to dehydration, and can even change the chemical make-up of your blood.

One case study published in the Journal of Investigative Medicine explains that, "in face of stress, the harmless 'dietary ketosis' can lead to profound acid-base disturbances due to massive overproduction of ketone bodies that overwhelms the acid buffer system of the body."

After beginning a keto diet, signs your body is in a state of "full" ketosis include bad, fruity-smelling breath and urine, as well as a cluster of symptoms referred to as keto flu, which include: "brain fog, headache, chills, sore throat, digestive issues, dizziness, insomnia, irritability, and more."

Registered Dietitian and Counselor Audrey Tait says these symptoms are a natural byproduct of going keto.

"Brain fog happens when the body does not get enough of the right kind of carbohydrates," Tait explains. "The best sources of carbohydrates are whole grains, fruits, vegetables, legumes, and milk. The carbohydrates get broken down in the body into glucose. This glucose is used for energy to do work and energy for the brain."

Once the initial fog subsides, ketosis is said to actually improve brain clarity and overall energy levels, but I never made it to that point.

In addition to being used for weight loss, the ketogenic diet is believed by many to offer health benefits for people with certain medical conditions, including type 2 diabetes and epilepsy.

One article from Harvard Medical School explains as follows:

"We have solid evidence showing that a ketogenic diet reduces seizures in children, sometimes as effectively as medication. Because of these neuroprotective effects, questions have been raised about the possible benefits for other brain disorders such as Parkinson's, Alzheimer's, multiple sclerosis, sleep disorders, autism, and even brain cancer. However, there are no human studies to support recommending ketosis to treat these conditions ...

"A ketogenic diet also has been shown to improve blood sugar control for patients with type 2 diabetes, at least in the short term ... However, there is no long-term research analyzing its effects over time on diabetes and high cholesterol."

RELATED: What Happened When I Tried The Keto Diet

As I quickly discovered, the ketogenic diet is not for wimps. It is an extreme and notoriously difficult diet to follow.

Being on a restrictive keto diet for a long time could potentially mess with your metabolism, not to mention your cholesterol levels, since you essentially gorge on fat all day long.

A keto diet may also come with a host of unpleasant, even dangerous medical issues, including:

  • constipation
  • hypoglycemia
  • vitamin deficiencies
  • kidney stones
  • balance issues
  • loss of bone density
  • headaches
  • lightheadedness
  • menstrual irregularities
  • dehydration
  • As mentioned above, I've tried other high-fat, low-carb diets in the past, and they were predictably hellish-but-doable.

    This time (maybe because I'm over 40 and 20 pounds heavier) was different.

    From day one, keto turned me into a monster.

    My irritability was intolerable. When I wasn't frantically Googling how to make keto "bread" (using fairy dust and a dozen eggs) and racking up my grocery bill with obscure ingredients like xanthan gum and psyllium husk, I paced the kitchen like a Bengal tiger.

    Whoever dared come too near risked getting mauled to within an inch of their life.

    Needless to say, my family was terrified. Even the dog gave me a wide berth.

    Across the dining room table, my husband shot my son a look of solidarity, as if to say, "Don't worry, kid, we will get through this dark time together. Your mother will come back to us ... Like she always does. In the meantime, we must exercise great caution. We must be strong and stick together."

    It's no exaggeration to say that my hunger consumed me.

    I foraged cupboards, looking for anything I was allowed to have. It wasn't long before rich slabs of brie and rashers of bacon lost their luster and I learned that the rich buttery goodness of butter is only at its best when it is slathered on something other than thin air.

    Although some report feeling satiated on a keto diet, I felt the complete opposite. When I wasn't eating, I was dreaming about eating. I had trouble thinking of anything else.

    Tait confirms that experiencing this kind of extreme irritability is not uncommon.

    But the worst part of the ketogenic diet wasn't even the carb withdrawal.

    After the first week of torture, I'd dropped a measly 2 pounds. A of couple days later, I bounced back to my starting weight. A few days on, I was down 4 pounds.

    By the end of the second week ... right back where I started.

    It felt like that bastard scale was playing me.

    RELATED: Details About The Rumored Smelly Side Effect Of The Keto Diet

    Although most people manage to lose weight quickly on keto, I was not most people.

    Maybe I was eating too much protein or too many veggies — who knows? But one thing had become abundantly clear: I'd never feel happy on keto.

    In addition to being hungry all the time on the ketogenic diet, I had no energy to exercise.

    Although the feeling of running on empty is supposed to pass after a while, I wouldn't know, because I never made it that far. I lasted just over two weeks.

    All told, I lost not a single pound ... or maybe I lost a couple. By the time I quit, it didn't matter.

    That final night, I celebrated the end of keto with a generous glass of Riesling and promptly kissed those theoretical lost pounds goodbye.

    If only I could eat what I should, when I should — they call that "intuitive eating".

    But food is never just food, is it?

    It is a missile. It is a grail. It's those damn skinny jeans.

    My mother, who dislikes cooking intensely, once wished for a pill humans could take to avoid meal prep. At first the thought depressed the hell out of me because what's a life without food? Without all the smells and textures, the smorgasbord of tastes and the ritual of eating together ...

    But after all the years I've spent obsessing about food, I must admit that pill is looking more appealing. I wish someone would hurry up and invent it already.

    In the meantime, I will hold out for the next faddish diet and pray that it's kinder than keto.

    What Happens to Runners on a Ketogenic Diet?

    Think of this article as a Rorschach test. I'll describe some data from a recent experiment; you decide for yourself what meaning to extract from it. This, as far as I can tell, is the only safe way to write about low-carb, high-fat (a.k.a. ketogenic) diets for endurance athletes, without getting bogged down in endless debates about your motives, word choice, and sanity. So here goes nothing!

    The study in question, newly published in Medicine & Science in Sports & Exercise, comes from a group at the Sports Performance Research Institute New Zealand at Auckland University, led by doctoral student David Shaw. It's not a perfect study, but it has some notable strengths compared to a lot of diet-related research: a randomized trial with strict dietary control, and a 31-day period to adjust to the unfamiliar diet. And it tackles a very simple but athletically important question: do you get faster on a ketogenic diet, which is designed to teach your body to rely almost exclusively on fats and ketones (a supplementary fuel that your body produces in the near-absence of carbohydrate)?

    Some details: the study started with 10 trained male endurance athletes, all sub-3:30 marathoners running more than 30 miles per week, none with previous experience on a ketogenic diet. Two of them failed to stick to the study's conditions, so the final analysis includes 8 subjects. All of the subjects, in randomized order, completed two 31-day protocols: one consuming their normal diets, the other on a ketogenic diet, with a series of performance and physiological tests before and after each 31-day block. 

    The normal diets for these particular people averaged 42.9 percent carbohydrate, 38.5 percent fat, and 18.6 percent protein. The prescribed targets for the ketogenic diet were less than 50 grams per day of carbohydrate, 15 to 20 percent of calories from protein, and 75 to 80 percent from fat. The subjects were given free coconut oil, olive oil, LCHF cereal, and discounted fruits and vegetables, and their dietary reports were carefully monitored. They ended up averaging 34 grams of carbohydrate per day (4.1 percent of their calories), with 77.7 percent of their calories from fat and 18.2 percent from protein. Regular blood and urine tests confirmed that the subjects were indeed consistently in ketosis.

    There were two basic assessments. One was a progressively accelerating treadmill test, which allowed the researchers to measure VO2max at exhaustion, and also to assess efficiency at a range of different speeds as the treadmill accelerated. The other was a plain old run to exhaustion at pace equivalent to 70 percent of VO2max, which the subjects could maintain on average for about four hours (so, in other words, significantly slower than marathon pace, which is typically somewhere around 80 percent of VO2max). During the run to exhaustion, they either received a carbohydrate-based sports drink (during the normal diet trial) or an artificially sweetened drink with the same number of calories from coconut oil (during the ketogenic trial).

    In the efficiency test, there was no difference between the diets at the lower speeds corresponding to below about 60 percent of VO2max. Once the pace picked up to above 70 percent of VO2max, however, the runners on the ketogenic diet became significantly less efficient: they needed more oxygen and more energy to sustain a given pace. Their VO2max itself—that is, the maximum amount of oxygen they could use per minute—stayed the same on both diets, but the speed they could run at while consuming that oxygen was lower on the ketogenic diet.

    Interestingly, that echoes what Kieran Clarke, the co-developer of the ketone ester drink sold by HVMN, told me last year: "As soon as you're up to 75 percent of your maximum workload," she said, "I wouldn't even go near a ketone."

    That makes the run to exhaustion extra-interesting, because it was at 70 percent of VO2max, right around the threshold where efficiency seems to start suffering. So here's the Rorschach part of the article. On the left, you've got the before-and-after results for each of the eight subjects on their habitual diet (plus the average results with standard deviations shown); on the right, the same thing for the 31-day ketogenic diet.

    So what's the verdict? The statistical analysis tells us that time to exhaustion was similar in both conditions: the average times before and after the ketogenic diet were 239 and 219 minutes, respectively, with a p value of 0.36. Three of the subjects lasted longer; five gave up sooner. The variation is much higher than after the habitual diet: some seem to have thrived, others tanked.

    The big question is how much we can or should read into those results. Would the three people who got better have shown similar results in another test a week later? A month later? How about the five people who got worse? Or is it just random scatter, since time-to-exhaustion tests are very sensitive to small perturbations in how you're feeling?

    The researchers offer one speculative answer to this question. You can divide the subjects into two groups based on their respiratory exchange ratio (RER) at the end of the VO2max test. The RER is the ratio between exhaled carbon dioxide and inhaled oxygen, and (with a few caveats) it tells you what mix of fat and carbohydrate you're burning: a value of 0.7 corresponds to pure fat, 1.0 corresponds to pure carbohydrate, and greater than 1.0 suggests you're going so hard that you can't supply oxygen quickly enough and are adding a significant amount of anaerobic energy.

    After 31 days of ketogenic diet, all the subjects had ramped up their fat-burning abilities (which is good), but had also lost some of their carbohydrate burning abilities (which is not good, particularly at near-maximal intensities where you're consuming energy very rapidly). In their post-keto VO2max test, 4 of the subjects had a final RER above 1.0, suggesting that they could still access carbohydrate and anaerobic energy at a reasonable rate, while the other 4 had a final RER below 1.0. Those with the lower RER were the ones who subsequently struggled in the time-to-exhaustion test: their average time decreased significantly by 237 to 174 minutes, and they had higher lactate levels at the end of the test. In contrast, those with the higher RER had lower lactate levels and no significant change in time to exhaustion (increasing from 241 to 265 minutes).

    Again, this is a highly speculative suggestion. The interpretation of RER at high intensities is problematic, and combing through post-hoc sub-groups of 4 people is a good way of finding patterns that don't really exist. But it's an idea to file away for future investigation: could a simple measurement of RER at VO2max give you a quick and reliable way of predicting who's likely to perform well or poorly once they've adjusted to a ketogenic diet?

    One final historical note: it's interesting to see how many echoes there are here from Stephen Phinney's 1983 paper on four weeks of ketogenic diet for cyclists, which has near-scriptural status in the ketogenic community. In Phinney's study, fat-burning was ramped up but high-intensity power was throttled: he noted "a severe restriction on the ability of subjects to do anaerobic work." In a time-to-exhaustion test, there was no significant change on average (147 to 151 minutes), but huge individual variations: one of the five subjects improved from 148 to 232 minutes, another decreased from 140 to 89 minutes. Shaw's new results seem surprisingly similar.

    To sum up the key points from the inkblot: at speeds faster than 70 percent of VO2max (i.e. well below marathon pace), efficiency was significantly impaired on a ketogenic diet. At speeds slower than 60 percent of VO2max, efficiency was unchanged. Right at 70 percent VO2max, time to exhaustion was unchanged on average—but the individual results in the graph above suggest the possibility of a more nuanced picture. You can decide which dot you think you'd be.

    Kourtney Kardashian Details Her "Strict" Approach to the Keto Diet

    Kourtney Kardashian is generally known to fans as a disciplined eater, having discussed her weekly fast and her firm anti-dairy stance in the past. But she's also opened up about relaxing that plan when life circumstances require it.

    On her new lifestyle website Poosh, she described how her approach to restrictive dieting dovetails with her opinion that it must be balanced in order to work — and be sustainable.

    "I cheat twice a day with a little something sweet after lunch and dinner," she said. "But when I did the Keto diet, I was very strict six days a week and my cheat day was on Sundays."

    And — in keeping with Kardashian M.O. about most things — she didn't do cheat days halfway. "I'd go to the farmers market before church and get a matcha latte and chocolate croissant from Alfred's, and then after church, I'd head to Soho House for their buffet (all-you-can-eat waffles with butter and syrup)," she wrote. "On my recent trip to Turks, we had a handful of junky foods, like Double Stuf Oreos and Cheetos for all of us to snack on."

    How A High-Fat Keto Diet Could Affect Your Gut Microbiome

    Keto fast became the flavour of the month (well… the past year), but now science is set to rock the diet staple off its perch.

    According to the latest research from the Gut Medical Journal, a high-fat diet may affect the gut microbiome in a less than favourable way.

    With the ketogenic diet working with a 60 to 70 per cent high-fat diet ratio in order to propel the body into ketosis (a process that breaks stored fat into molecules known as ketones to generate energy), the results of this new study are not looking good for keto fans.

    While proven by science to be effective for weight loss, in this new study, researchers assigned 217 healthy 18-35 year olds to a low fat (20 per cent), moderate fat (30 per cent) and high fat diet (40 per cent) over six months and found that those on the high-fat diet not only experienced a change in the bacterial communities (microbiome) of their gut but showed increased biomarkers of inflammation.

    To look deeper into the negative impact, they conducted a faecal test to look at the diversity of gut microbiota and also measured the blood before and after to determine inflammation levels.

    The results found after six months, the high-fat dieters microbiomes had a decrease in the beneficial bacteria said to produce short-chain fatty acids—the molecules responsible for helping regulate inflammation in the body and protect the cells that line the intestines.

    In contrast, those who ate a low-fat diet showed an increase in the same beneficial bacteria after six months. Whereas, the high-fat diet group only increased the bacteria levels associated with those who have type 2 diabetes.

    Yikes! Even more worryingly, their research determined high fat as 40 per cent, while the ketogenic diet works on a 60-75 per cent fat ratio… so, reading between the lines… you can only wonder what the effect on a keto devotees gut could be.

    Following a keto diet currently and unsure whether to be pro high-fat diet or not? While the microbiome research is up to date, according to Harvard University the verdict on its long term effects are yet to be determined. Which means, for now, the best way to give your gut some love according to Harvard? Skip the daily B.L.A.T (Bacon, lettuce, avocado and tomato sandwich) and stick to a wholefood Mediterranean diet high in colourful fruit and veg, lean meats, fish, wholegrains, nuts, seeds, olive oil and good old H20.

    After all, you know what they say… happy gut, happy mind!

    Weight loss diet: Man followed this keto style meal plan and lost belly fat for a six pack

    Reddit user 'Noahistheguy' posted the before and after weight loss images to his account.

    He proudly showed off a new, drastically different physique.

    Almost unrecognisable, he now boasts six pack abs - plus a smile.

    Wearing the same shorts, they looked far, far tighter in the before picture.

    Weight loss diet plan: How men shed belly fat and 3.2 stone for six pack abs

    The 25-year-old man detailed exactly how he lost the weight.

    Initially the dieter weighed 15 stone, or 210lbs. Now, he weighs a much lighter 11.7 stone.

    So what weight loss rules did he follow? The young man wrote that he went though "five months of 1500 calories a day, HIIT sprints, gruelling workouts, and not eating after 7 pm."

    It seemed that he followed a keto style, low-carb weight loss diet, as he detailed what he ate in one day.

    He revealed that for breakfast he ate "10 egg whites with a little salsa and 1/2 cup of oatmeal with 1/2 cup of frozen berries."

    As a mid morning snack he had a protein bar before having a protein heavy, low fat lunch of "10 oz chicken breast and as much broccoli as (he) wanted".

    As an afternoon snack he had a protein shake before having "4 pieces tilapia, 1/2 cup of quinoa, unlimited asparagus, and 1/2 an avocado" for dinner.

    He also imparted some secondhand weight loss knowledge.

    "A wise man much buffer and more tan than I'll ever be once told me, 'if it tastes good, spit it out.' Best weight loss advice I've ever gotten," he wrote.

    He is not the only internet user to lose a huge amount of weight following a weight loss diet plan.

    Size 20 woman shows off weight loss on Save Money Lose Weight – but can’t stick at keto diet

    A WOMAN who tipped the scales at nearly 20 stone was shocked to discover she'd lost more than a stone in just 28 days while following the vegan keto diet.

    Holly, 30, had ballooned to a size 18-20 from a size six to eight, after her partying days of drinking and kebabs saw her reach 19st 1lbs.

     Holly had a BMI of 44.4, and weighed more than eight stone above her recommended weight

    Standing at 5ft 5ins, insurance worker Holly had a BMI of 44.4, and was more than eight stone heavier than the recommended weight for her frame.

    She's the latest participant to appear on ITV's Save Money Lose Weight, which this week road tested the vegan keto diet, combining two popular diets already on the market.

    Holly, from King's Lynn, said her love of stodgy food was partly to blame for her weight.

    She said: "I guess like a lot of carbs, I eat a lot of toast.

     She used to be a size six to eight, but was now a size 18 - 20

    "And the fact I eat at weird times is where I struggle.

    "Maybe a little bit of portion size, living on your own is quite difficult to make the right amount.

    "And then you feel like you've just got to eat it all.

    "I tend to snack more when I'm sad or if I'm feeling a bit emotional. So that does tend to be a trigger for me, eating stuff that I shouldn't.

     Holly, middle, said portion control was hard as she lived on her own

    Starting off her 28-day diet, Holly's food for the next month involves a lot of vegetables, seeds, nuts and tofu, with Holly admitting she "doesn't really know what it is".

    She is restricted to 20-50g of carbs and 1700-200 calories a day, saying: "Apparently I'm going to wee oil and I may be constipated for a little while.

    "But apparently after that it's all smooth sailing."

    On the menu are dishes such as zucchini Alfredo, cauliflower soup and steamed spinach, lemon poppy seed muffins and chia and almond butter pudding, which she says is like "fruity Weetabix".

     The aim of the diet is for Holly's body to enter ketosis

    Testing her urine at the beginning of the experiment – which is how she can tell if her body is in ketosis – she measures just above negative, acknowledging she's "got a long way to go".

    As the weeks go on and Holly has very little carbs, her body goes into ketosis, were it burns fat instead of glucose.

    But the diet begins to take its toll, with Holly reporting flu-like symptoms, often known as the Keto-flu.

    She perseveres until the end, despite saying: "Being vegan is fine, you can still have your carbs, but adding keto is just impossible.

     Holly says her partying lifestyle was partly to blame for her weight gain

    "Although I'm in ketosis there's no option for you to be able to go out have a drink, have food, your social life just crumbles."

    When it came to that all-important weigh in, Holly was shocked to discover she'd lost a whopping 1st 6lbs, dropping down to 17st 9lbs.

    She lost five inches from her waist, but most importantly the diet cost her £281.88 for the month - £14.09 for every pound lost – meaning the diet was ranked second overall.

    Holly said: "In 28 days, yeah I'm happy with that.

    "To lose that much around my waist, I'm really pleased with that."

    But when asked if she'd continue, she said: "You couldn't pay me to continue with the diet. I just can't handle any more seeds.

    "I'm sorry vegan keto, it's goodbye from me."

     Despite the good results, Holly says she wouldn't continue with the diet
