Keto Esters: Weight Loss Miracle Or Myth?

Ketone esters are supplements that claim to put your body into ketosis without following a ketogenic diet. When in ketosis, the body burns fat for fuel instead of carbohydrates, which can result in weight loss. However, ketone esters are not a magic bullet for weight loss. While they can increase ketone levels in the blood and suppress appetite, they also contain calories and may not affect appetite as much if consumed after a meal. Additionally, ketone esters can be expensive and may cause side effects such as nausea and dizziness. More research is needed to fully understand the weight loss benefits of ketone esters.

Ketone esters are unlikely to lead to weight loss

Ketone esters are supplements that can be consumed as drinks, pills, or drops. They are designed to put the body in ketosis without following a keto diet. While in ketosis, the body burns fat for fuel, which is usually reached by following a high-fat, low-carb diet or through fasting. However, despite ketone esters' promise of weight loss, they are unlikely to lead to it. Here's why:

Firstly, ketone ester drinks are not low-calorie. Adding these drinks to your diet without cutting calories from other meals can hinder your weight loss goals. For example, a new brand of keto ester drink contains 210 calories. Consuming this drink without reducing calories from other meals may lead to weight gain rather than weight loss.

Secondly, while ketone esters may suppress appetite, they also inhibit fat breakdown. Ketone supplements can raise blood ketone levels, which, in excess, triggers a healthy person's feedback mechanism to slow down the production of ketones. As a result, taking ketone supplements may prevent body fat from being used as fuel, at least in the short term.

Thirdly, ketone esters contain calories. With around four calories per gram, the same as carbs or protein, ketone ester supplements are not ketogenic as they prevent the body from producing its own ketones and provide a source of calories. To maintain ketosis, multiple servings of these supplements are needed throughout the day, which can be costly.

Lastly, there is limited research on the effectiveness of ketone esters for weight loss. While ketone esters may help induce ketosis, it is unrealistic to assume that they can maintain ketosis alongside an unsuitable diet. Weight loss is a complex process influenced by various factors, and relying solely on ketone esters without addressing dietary habits is unlikely to lead to significant or sustainable weight loss.

While ketone esters may offer some benefits, such as improved athletic performance and cognitive function, the available evidence suggests that they are not a magic bullet for weight loss. A well-rounded approach to health and weight management involves a balanced diet, regular exercise, and addressing any underlying health conditions or lifestyle factors that may impact weight.

Ketone esters can suppress appetite

Ketone esters are supplements that claim to put your body into ketosis without following a ketogenic diet. When in ketosis, the body burns fat for fuel, which is usually achieved by following a high-fat, low-carb keto diet or through fasting.

In addition to potentially suppressing appetite, ketone esters offer several other benefits. They can provide increased energy, improve mental clarity, enhance cognitive function, improve muscle recovery, and increase athletic performance.

However, it is important to note that research on ketone esters is limited, and they may have unpleasant side effects such as nausea and dizziness. They are also expensive and may not be necessary for weight loss or overall health. As with any supplement, it is always a good idea to consult with a healthcare professional before incorporating ketone esters into your routine.

Ketone esters are expensive and unpleasant-tasting

Ketone esters are expensive. The first two brands to hit the market in 2018, KetoneAid and HVMN, cost $94.95 and $99 respectively for three servings. A 2021 article in Business Insider describes them as "costly".

They are also known to be unpleasant-tasting. GQ's Brennan Kilbane described the taste of HVMN as "like a mixture of vodka, tequila, vegetable oil, and battery acid". Business Insider reporters Melia Robinson and Erin Brodwin tried HVMN and said: "It caused our eyes to tear. We gagged, loudly." Another reviewer said: "I have never tasted gorilla urine, but I imagine that it tastes better than this product."

However, some people are willing to overlook the taste due to the benefits of the product. One reviewer said: "no one in their right mind would drink this if it didn't provide results!" Another said: "Works Great. Taste terrible. no one in their right mind would drink this if it didn't provide results!"

The taste of KetoneAid Pro KE4 has improved but is still not "up to the standards of something that you would purchase from your local juice bar". The flavour is named "Very Scary Cherry".

Ketone esters can help with muscle recovery after exercise

Ketone esters are a popular dietary supplement that can help with muscle recovery after exercise. They are especially beneficial for those who need to limit their carb intake but still need energy to get through the day.

One of the drawbacks of entering ketosis is fatigue, which is one of the many symptoms that low-carb dieters will likely experience. Ketone esters offer an antidote to this fatigue. On a biochemical level, ketone esters can bypass the brain's blockage of the path to using sugar for energy, which offers a variety of benefits.

A study by Vandoorne et al. (2017) found that ketone monoester, when taken with a standard post-exercise recovery beverage, enhances the post-exercise activation of mTORC1, a mechanistic target of rapamycin complex 1, which is a key regulator of skeletal muscle protein synthesis following exercise.

Another study by Poffe et al. (2019) showed that ketone monoester supplementation blunted overreaching symptoms during endurance training overload. The researchers put subjects through an increasingly difficult 3-week period of high training intensity and volume to induce a state of non-functional overreaching and limited recovery. The subjects who received ketone supplementation were observed to increase their overall food intake in proportion to their training, voluntarily ingesting more carbohydrates over the course of the study. The researchers concluded that ketone esters ingested after exercise and before bed improved test subjects' ability to recover during heavy training.

Ketone esters can be consumed in various forms, such as drops, pills, or drinks. They are generally safe according to the FDA, but some people may experience negative side effects such as nausea or dizziness.

Ketone esters can improve cognitive function

Secondly, ketone esters can help reduce inflammation in the brain, which is often associated with various neurological disorders and cognitive impairments. By reducing inflammation, ketone esters may help improve cognitive function in conditions such as Alzheimer's disease, epilepsy, and dementia.

Thirdly, ketone esters can protect neurons from damage caused by hypoglycemia (low blood sugar) and oxidative stress. This neuroprotective effect is due to their ability to stimulate mitochondrial ATP production and reduce the production of reactive oxygen species (ROS).

Additionally, ketone esters can improve cognitive function by serving as an alternative fuel source for the brain. The brain typically relies on glucose for energy, but in states of low glucose availability, such as during fasting or calorie restriction, ketone esters can provide an alternative fuel source, helping to meet the energy demands of the brain.

Furthermore, ketone esters can improve cognitive function by enhancing the production of certain neurotransmitters, such as aspartate and glutamate, which are essential for proper brain function.

Lastly, ketone esters can positively impact cognitive function by
