The ketogenic or keto diet is a very low-carb, high-fat diet. The goal of the diet is to lose weight without hunger or cravings. The diet aims to put your body into a state of ketosis, which is a metabolic state where your body burns fat for fuel. While the keto diet can lead to short-term weight loss, it is not recommended for long-term weight loss due to possible health risks, including nutritional deficiencies. To achieve ketosis, one must restrict their carbohydrate intake to less than 20-50 grams of carbohydrates per day. This can be challenging as it involves cutting out grains, starchy vegetables, alcohol, and sugar. As a result, some people turn to keto supplements or keto pills, which are said to help the body achieve ketosis more quickly and efficiently. However, there is limited research on the effectiveness of these supplements, and they may have unintended consequences for your health.

What You'll Learn
Ketone supplements can reduce symptoms of the keto flu
The keto flu is a collection of symptoms experienced by some people when they start a ketogenic diet. The symptoms can include headache, weakness, irritability, constipation, nausea, and vomiting. The keto flu is caused by the body adapting to a new diet consisting of very few carbohydrates. This drastic reduction can come as a shock to the body and may cause withdrawal-like symptoms.
Ketone supplements can help reduce the symptoms of the keto flu. Ketone supplements can mimic ketosis and raise blood ketone levels without changing your diet. This reduction in appetite can be beneficial when nausea from keto flu makes it difficult to eat. However, ketone supplements may not affect appetite as much in people who have recently eaten a meal.
In addition to ketone supplements, there are other ways to reduce the symptoms of keto flu. Staying hydrated by drinking lots of water can help prevent dehydration, a common issue when starting a keto diet. Getting enough sleep and rest can also help combat the fatigue caused by keto flu. Finally, eating more salt or drinking sports drinks that are high in electrolytes can help replace lost electrolytes and improve symptoms such as fatigue, muscle cramps, and body weakness.

Ketone supplements may decrease appetite
Ketone supplements have been shown to decrease appetite, which may help with weight loss. In a study of 15 people of normal weight, those who drank a beverage containing ketone esters experienced 50% less hunger after fasting overnight than those who drank a sugary drink. This appetite-suppressing effect was attributed to lower levels of the hunger hormone ghrelin between two and four hours after drinking the ketone ester drink.
However, ketone supplements may not affect appetite as much in people who have eaten a meal beforehand. Studies have observed higher blood ketone levels in those who did not eat before taking a ketone supplement compared to those who did. Since elevated ketones are associated with reduced appetite and lower ghrelin levels, ketone supplements may only be beneficial during a fast, such as in the morning, rather than after a meal containing carbohydrates.
In other words, taking a ketone supplement after a carbohydrate-containing meal will still raise blood ketone levels but not as high as if you had fasted, suggesting that your body uses fewer ketones as fuel since there is more available glucose from the carbohydrates. One small study found that exogenous ketone supplements reduced appetite for over four hours, which may be promising for weight loss. However, more studies are needed before ketone supplements can be recommended for appetite control.
While ketone supplements may decrease appetite, their potential weight loss benefits are unknown. Therefore, ketone supplements cannot be recommended for weight loss at this time. In fact, some evidence suggests that they may hinder weight loss.

Ketone supplements are expensive
The cost of ketone supplements is further compounded by the fact that they are not a one-size-fits-all solution. They should be taken as part of a comprehensive strategy that also includes a balanced diet, frequent exercise, and healthy lifestyle choices. Additionally, the effects of ketone supplements only last a few hours, requiring repeated doses throughout the day to maintain ketosis. This can further increase the financial burden, as well as the risk of side effects.
It is also worth noting that the Food and Drug Administration (FDA) does not regulate dietary supplement claims as rigorously as pharmaceutical drugs. This means that supplement companies are not subject to the same strict processes to prove their effectiveness, purity, or marketing claims before entering the market. As a result, some claims made by ketone supplement companies may overstate the benefits of their products.
While ketone supplements may provide certain benefits, such as improved athletic performance and reduced appetite, their high cost is a significant factor to consider.

Ketone supplements may mess with your metabolism
Ketone supplements are thought to mimic ketosis and raise blood ketone levels without the need for dietary changes. However, they may mess with your metabolism in several ways.
Firstly, ketone supplements can cause an electrolyte imbalance. Electrolytes are vital for the proper functioning of muscles and the maintenance of a normal heart rhythm. An imbalance can be particularly harmful if you have a kidney condition that already affects your body's ability to maintain balanced electrolyte levels.
Secondly, ketone supplements can lead to hypoglycaemia or low blood sugar. This is dangerous if you have diabetes and take medications that lower blood glucose levels. The extra ketones from supplements may lead to hypoglycaemia, resulting in fatigue and lethargy.
Additionally, ketone supplements can heighten the dehydrating effects of a keto diet, making you more prone to dehydration. Dehydration is serious and can lead to lightheadedness, kidney injury, or kidney stones. It may also increase the risk of cardiac arrhythmia as electrolytes are necessary for a regular heart rhythm.
Furthermore, ketone supplements may prevent body fat from being used as fuel, at least in the short term. The purpose of the keto diet for weight loss is to produce ketones from stored fat. However, if your blood ketone levels become too high, your body has a feedback mechanism that slows down ketone production. As a result, taking ketone supplements may hinder weight loss efforts.
Lastly, ketone supplements can be expensive, and there is limited research on their long-term effects. They may also have unpleasant side effects, such as nausea, vomiting, diarrhoea, and stomach discomfort.
In conclusion, while ketone supplements may offer some benefits, it is important to be aware of their potential impact on metabolism and overall health. It is always recommended to consult a doctor or healthcare professional before taking any supplements.

Ketone supplements may cause digestive issues
Ketone supplements are available in the form of either ketone salts or ketone esters. Ketone salts are made by adding artificial ketones to electrolytes such as sodium, calcium, magnesium, and potassium. These are usually found in drink form or in powders or pills. Ketone esters are the purest form of ketones and therefore the most potent. They are also expensive and have an unpleasant taste.
Ketone supplements can cause digestive issues, including stomach distress and increased bowel movements. They can also cause an electrolyte imbalance, which can be harmful if you have a kidney disease that already affects your body's ability to maintain balanced electrolyte levels. Electrolytes are vital for your muscles to function properly and for your heart to maintain a normal rhythm.
In addition to digestive issues, ketone supplements may also cause other side effects such as nausea, diarrhea, and stomach discomfort. These side effects are more common with ketone salts than with ketone esters.
