While the keto diet has gained popularity for its potential weight loss benefits, there are some potential dangers to be aware of. These include adjusting diabetic medication due to low blood sugar, excessive intake of saturated fats increasing the risk of heart disease, and potential side effects such as low blood pressure, kidney stones, constipation, and nutrient deficiencies. It is important to consult with a healthcare professional before starting any new diet to assess whether it is suitable for your individual needs and health conditions.
Understanding The Keto Diet
The ketogenic diet, commonly referred to as the “keto diet,” is a high-fat, low-carb diet that has gained significant popularity in recent years for its possible weight loss benefits. However, what many may not know is that it was initially developed to manage epilepsy in children, and research on its effectiveness for obesity or diabetes is limited. The primary goal of the keto diet is to achieve ketosis, which is a metabolic state where the body breaks down fat for fuel instead of glucose from carbohydrates. Achieving ketosis requires eating about 75% of calories from fat, 5% from carbohydrates (20-50 grams per day), and 15% from protein. It typically takes about 72 hours to enter ketosis.

Recommended foods include fatty fish, eggs, dairy products, meat, butter, oils, nuts, seeds, and low-carb vegetables. On the other hand, fresh fruits and vegetables, whole grains and low-fat dairy are restricted since they contain more carbohydrates. It’s essential to note that keto-branded products and supplements are unnecessary since you can obtain all nutrients needed through whole foods.
Potential dangers of the keto diet include adjustment of diabetic medication due to low blood sugar; excessive intake of saturated fats raises the risk for heart disease; low blood pressure; kidney stones; constipation; nutrient deficiencies; increased risk of heart disease; social isolation or disordered eating. Not safe for those with conditions involving pancreas, liver, thyroid or gallbladder.
To better understand how this works in practice – imagine you’re used to consuming an average American diet rich in carbs and sugars. Suddenly switching your daily caloric intake to 75% fat could result in various short-term side effects as your body adjusts.

Switching from a carb-heavy diet to one high in fat can result in various short-term side effects as the body adjusts.
Short-Term Side Effects
The switch from using glucose as an energy source to burning ketones as its primary energy source (ketosis) can result in short-term side effects commonly known as the “keto flu.” These symptoms may include fatigue, headaches, brain fog, nausea, irritability, constipation, and weakness. Fortunately, these side effects are temporary and usually subside within a few days to a week.
Imagine your body is a car that has been running on gasoline for years. Switching to ketones as your primary fuel source would be like converting this gas-guzzling car into an energy-efficient electric car. During the conversion process, you may encounter some problems such as unfamiliar controls or touch screens and require some time to learn how to utilize all the new features effectively.
Another potential short-term side effect is hair loss–a common concern among those practicing keto. While many blame the keto diet directly for hair loss, it’s often a result of rapid weight loss itself rather than the diet. When coupled with inadequate micronutrient intake (especially biotin and zinc), hair loss becomes more prevalent. The best way to counteract this is by ensuring a safe calorie deficit and sufficient micronutrients, such as collagen supplements, consuming bone broth and green vegetables rich in biotin.
It’s also important to incorporate plenty of fiber-rich foods into your meals, such as chia seeds or flaxseeds since low-carb diets tend to be low in fiber content; although this can cause minor diarrhea initially. Drinking enough fluids is equally important since dehydration can worsen these digestive symptoms.
Now that we’ve covered some of the short-term side effects commonly experienced while adjusting to the keto diet let’s take a closer look at one particular symptom: keto flu.
- A 2019 review in The Lancet found that people who consumed a low-carb diet had a 20% higher risk of stroke than those who consumed a balanced diet.
- A study in the Journal of American Heart Association (2019) revealed that individuals following low-carb diets, including keto, have an increased risk (18%) of developing atrial fibrillation – a common heart rhythm disorder.
- According to the US National Institute of Diabetes and Digestive and Kidney Diseases, approximately 15% of people on ketogenic diets experience kidney stones – a rate almost double that of the general population.
Keto Flu
As with any drastic dietary change, the keto diet comes with a set of side effects that can be alarming for beginners unfamiliar with this way of eating. One of the most common side effects is ironically called the keto flu. This generally refers to the body’s response to carbohydrate restriction and shift towards using ketones as fuel.
During this transition, which typically occurs within the first week, individuals might experience fatigue, headaches, dizziness, nausea, difficulty sleeping (insomnia), or decreased athletic performance. These temporary symptoms have drawn comparisons to flu-like symptoms – hence the name – and can feel overwhelming at times.
I recall feeling lethargic and irritable when I first attempted a ketogenic diet several years ago. My body was taking time to adjust to the metabolic switch from carb-burning to fat-burning. It took about five days before my energy levels increased and began feeling like myself again. However, not everyone experiences keto flu symptoms; some adjust without any issues.
To help alleviate such symptoms, consider consuming foods that are rich in electrolytes – such as sodium, magnesium, and potassium – staying hydrated and active while your body adjusts.
Digestive Issues
While some individuals on a ketogenic diet report an improvement in digestive health issues such as acid reflux or Irritable Bowel Syndrome (IBS), it may pose problems for others. One primary cause for concern is constipation, as the lack of fiber and high-fat intake may lead to infrequent bowel movements.
Think of your digestive tract like a conveyor belt; it keeps things moving smoothly unless there’s no traffic jam ahead. In simple terms: less fiber = lesser bowel movement = discomfort.
However, this issue can be mitigated by increasing fiber content through sources like leafy vegetables, nuts & seeds, flaxseeds etc., drinking plenty of water and staying active. It’s also important to increase fiber intake gradually to avoid shocking your body with an abrupt change in diet. If constipation persists, medical intervention may be necessary.
Another digestive issue some individuals may encounter on a ketogenic diet is diarrhea. This could occur due to the sudden increase of MCTs or medium-chain triglycerides. These are commonly found in coconut products or bulletproof coffee – a staple beverage on the keto diet.
Now that we’ve discussed two common side effects of the keto diet, it’s time to delve into more serious risks associated with this way of eating.
Potential Serious Risks of Keto Diet
While the keto diet has been gaining popularity among people looking to lose weight or manage certain health conditions, it’s essential to weigh its potential risks and side effects. Like any other dietary plan, the body reacts differently, and some individuals may experience severe symptoms while on the diet.
One of the most alarming risks associated with the keto diet is that it tends to increase bad LDL cholesterol levels and triglycerides in the blood, which can lead to heart disease. Additionally, research highlights potential nutrient deficiencies, kidney stones, liver problems and imbalanced blood sugar levels as other hazards associated with this diet.
However, some studies have proven effective for managing seizures in children with epilepsy; there isn’t enough scientific evidence supporting its effectiveness in treating obesity or diabetes. Therefore referring to a healthcare professional before adopting this sort of eating behavior is highly recommended.
Let’s go further into detail on how adhering strictly to the keto diet could increase one’s risk of developing heart disease.
Heart Disease
While initially marketed for managing seizures in children with epilepsy, nowadays many people take up the ketogenic diet in pursuit of weight loss. However, due to its drastic change in macronutrient proportions (high-fat intake), it has potential long-term dangers if followed strictly without correct supervision or nutritional balance monitoring.
When following the keto diet long term, it might result in elevating the concentration of bad LDL cholesterol. A high-fat consumption intake leads to an accumulation within arterial walls increasing a person’s propensity towards experiencing blood clots, heart attacks or strokes hence leading them down a path towards cardiovascular disease.
Furthermore, keto also restricts consumption of fruits and vegetables important for cardiovascular protection and chromium-rich whole grains known for promoting healthy insulin regulation [If you want me to explain more about this point please let me know].
It’s essential to remember that while brief periods of following the ketogenic diet may cause weight loss and temporarily lower blood sugar levels, it is not sustainable for a long-term. It may ultimately lead to weight regain and ultimately cardiovascular health issues if followed incorrectly.
While picking up any diet or lifestyle change, careful examination of its pros and cons should be done before adopting it – in that vein, it’s best to know your body’s nutritional requirements well, the fundamental science around how different diets affect metabolism; talk to healthcare professionals while making informed choices towards your health goals.
Nutrient Deficiencies
While the keto diet appears to have several health benefits, it can also lead to some severe side effects. One of the most significant potential adverse effects of following the keto diet is nutrient deficiencies. When you significantly restrict your carbohydrate intake and rely primarily on fats, it can limit your vitamin and mineral intake.
For example, cutting out fruits and whole grains – which are generally restricted on the keto diet – could lead to a lack of essential nutrients like Vitamin C, folate, and potassium, all of which are necessary for good overall health. Additionally, lacking these vitamins might cause other symptoms, such as fatigue and irritability.
Some essential minerals commonly found in carbohydrate-rich foods are calcium and magnesium. A decrease in these minerals from limiting carb-rich foods can lead to fatigue, cramps, bone degradation, and even impaired heart function. It’s important to note that incorporating keto-friendly food sources rich in calcium and magnesium can help alleviate these deficiencies.
On top of this, fiber consumption is often lower on a ketogenic diet which can result in digestion issues or constipation.
Although short-term studies indicate some tremendous weight loss benefits behind keto diets for specific populations, long-term risks should not go unnoticed as the consequences of chronic ketosis begin to reveal themselves.
Long-term Consequences of Keto
Originally designed as a therapeutic intervention for epilepsy treatment in infants and children, the ketogenic diet has become popular for its rapid weight-loss effects. However, there are several long-term concerns associated with following the diet past an initial weight-loss period.
Consuming substantial amounts of dietary fat especially those high in saturated fats- might cause problems with heart health if sustained over time. Elevated levels of ‘bad’ cholesterol can accumulate in arteries due to excessive saturated fat consumption increasing plaque formation and ultimately resulting in cardiovascular disease. It’s important to consider the impact eating an unbalanced amount of saturated fat could have on your overall health.
Long-term adherence to a ketogenic diet has shown to increase bone loss due to acidic urine from increased protein intake. A higher risk of developing osteoporosis can result from chronic acidosis and calcium deficiency.
The keto diet relies heavily on animal proteins and fats, which is associated with gut microbiome disruption leading to inflammation, bowel disturbance, and even mood changes. Incorporating plant-based fats such as nuts, seeds, avocados and non-starchy vegetables might help alleviate some potential gut-related side effects.
For example, former keto adherent Angela Mavridis suffered from bloating, constipation, diarrhea and gut pain while following the keto diet. After consulting with a licensed nutritionist, she realized that reintroducing whole food carbohydrates showed vast improvements in her gut health while still maintaining her weight loss results.
While the short-term gains of rapid weight loss from following the keto diet sound promising, it’s crucial to weigh these short-term rewards against the long-term risks. As always, it’s essential to consult with a doctor or registered dietitian before embarking on any new dietary plan.
Tips to Alleviate Keto Side Effects
While the ketogenic diet has become increasingly popular over the years, it does not come without its fair share of side effects. The “keto flu” is a widely known obstacle that many experience when they begin the diet. It refers to a cluster of symptoms such as nausea, headaches, fatigue, dizziness, irritability and constipation that are initially caused by dehydration and later muscle breakdown for energy as the body transitions to ketosis. Fortunately, there are several ways you can alleviate these side effects:
One effective way is by making sure you stay hydrated throughout the day. You can add mineral-rich foods or supplements (like magnesium) to your diet that will aid hydration. Electrolyte drinks are also commonly used in the keto community.
Another way of avoiding the pesky keto flu is by gradually transitioning into ketosis rather than abruptly cutting out carbs and entering ketosis. This will give your body ample time to adjust to the changes and prevent you from feeling its adverse effects.
Dietary fiber helps combat constipation, which is a common issue experienced when on a low-carb, high-fat diet like this one; ensure you get enough dietary fiber from vegetables and unrefined grains like oats – coconut flour is a popular addition to baked goods.
Insufficient intake of sodium and potassium causes dehydration which leads to fatigue, weakness, lightheadedness among other symptoms; replenishing electrolytes through bone broth or salt pills help stabilize these levels.,
However, if you’re still struggling with side effects even after implementing these measures, it’s always best to consult with your healthcare professional for personalized guidance.
While personal experiences shed light on how individuals respond differently to keto diets’ side effects – from mild symptoms to severe ones – expert views on this subject cannot be ignored either.
Expert Views Vs. Personal Experiences
Experts have mixed opinions on the ketogenic diet. On the one hand, it’s considered a powerful tool for reducing seizures in epileptic patients and a safe approach to fast weight loss. It is like how chemotherapy can damage healthy cells in addition to cancer cells; while keto might cause some undesirable side effects, the results seem worth it.
On the other hand, many health professionals warn about several potentially dangerous side effects that come with following this diet long-term. For instance, consuming high levels of saturated fats from animal sources may lead to cardiovascular disease and increase the risk of heart attacks. Experts also caution that keto diets’ impact on immune system weakening could make an individual more susceptible to infections.
Overall, while personal experiences provide unique insights into what life is like on a ketogenic diet, it always helps to consult with health professionals so you can make an informed decision that aligns with your health goals and commitment.
Frequently Asked Questions (FAQ)
What are the possible side effects of following a strict ketogenic diet?
Common side effects of a strict ketogenic diet include the infamous “keto flu” with symptoms such as headaches, fatigue, and irritability. Additionally, constipation, bad breath (known as keto breath), nutrient deficiencies, and potential changes in cholesterol levels are also possible. In rare cases, individuals may experience a condition called ketoacidosis if they have uncontrolled diabetes or are following an extreme version of the diet. While these side effects can be temporary and manageable, it is crucial to approach the ketogenic diet with caution and consult a healthcare professional before embarking on it.
Are there any potential health risks associated with a long-term keto diet?
Yes, there are potential health risks associated with long-term adherence to the keto diet. A key concern is nutrient deficiency, as the diet severely limits carbohydrate intake and can result in inadequate consumption of important vitamins, minerals, and fiber. Studies have also linked long-term ketosis to an increased risk of heart disease, due to higher levels of cholesterol and saturated fat intake.

Are there any specific groups of people who should avoid or be cautious with the keto diet?
Yes, there are specific groups of people who should avoid or be cautious with the keto diet. Pregnant or breastfeeding women, individuals with kidney disease or liver dysfunction, and those with certain metabolic disorders like porphyria should avoid the keto diet due to potential health risks. Additionally, children under the age of 18 should undergo careful supervision if considering this diet as their bodies have different nutrient needs for proper growth and development. According to a study published in JAMA Pediatrics in 2019, following a ketogenic diet for epilepsy treatment can lead to slower growth rates in children. It is always important to consult with a healthcare professional before embarking on any dietary changes, especially in these specific cases.
What are the potential long-term consequences of following a keto diet?
The potential long-term consequences of following a keto diet include nutrient deficiencies, increased risk of heart disease, and gastrointestinal issues. Since the diet restricts carbohydrates, it can lead to a lack of important vitamins and minerals found in fruits, vegetables, and whole grains. Moreover, a high intake of saturated fats from sources like bacon and butter may raise cholesterol levels and contribute to heart problems. Additionally, the drastic change in eating habits can disrupt gut health and cause digestive discomfort. Studies have shown that while the diet may lead to initial weight loss, its sustainability and safety over time are still uncertain. (Source: Harvard Health Publishing)
Can a keto diet lead to nutrient deficiencies or other imbalances in the body?
Yes, a keto diet can potentially lead to nutrient deficiencies or imbalances in the body. The focus on high-fat and low-carbohydrate foods may limit the intake of important micronutrients like vitamins C, D, and E, as well as minerals such as magnesium and potassium. Additionally, a study conducted by the National Institutes of Health found that participants following a ketogenic diet had increased levels of plasma homocysteine, which is associated with cardiovascular disease. It is crucial to ensure proper supplementation and a variety of nutrient-rich foods to mitigate these risks when following a keto diet.
