Benefits

Keto OS is designed around the ketogenic diet approach to weight loss.

A ketogenic diet is essentially a low carb, high fat and medium protein diet, which encourages the body to go into a fat burning state known as ‘ketosis’.

Keto OS uses ketones in their formula for two reasons; as a source of energy, and to elevate levels in the body to encourage fat burn.

This also means that you do not have to drastically cut carbohydrates from your diet to achieve ketosis.

Using Keto OS leads to the following benefits:

Fat Loss & Muscle Preservation

When trying to lose weight, it is important to ensure that the weight being lost is body fat  and not muscle mass.

Not only does losing fat over muscle mean you will look better, it also protects your metabolism from slowing down. (1)

Keto OS helps to burn fat by putting your body into a state of ‘ketosis’ within 30 minutes of taking the product.

Ketosis is a metabolic state that is characterized by an elevated level of ketones in body tissues. (2)

We produce ketones when we don’t have enough sugar to use for energy. We then require another source of energy to replace it, so the body uses fat for energy instead.

The liver turns available body fat into ketones (a type of acid) and releases them into the bloodstream. Once they are free flowing in the blood, muscles and other body tissues use them as a source of fuel. (3)

Simply put, ketones are naturally produced by your body as part of the fat burning process.

Furthermore, Keto OS includes l-leucine, a type of essential amino acid which has been proven to protect existing muscle mass while encouraging muscle gains. (4)

Basically, by using Keto OS, you are consuming ketones and fooling the body into a fat burning state whilst also protecting lean mass.

Supports Mood

As many as 16.1 million people in the US suffer from depression and low mood every year. (5)

In modern times we have busier, stressful lives which are taking their toll upon mood and general mental health.

If you are struggling to lose weight, this can understandably contribute to changes in mood and low self esteem.

Keto OS can help lift that low feeling and increase positivity.

It uses ingredients such as l-taurine, which are known for their beneficial impact upon the mood. (6)

Enhances Energy and Focus

Most people will experience fluctuations in energy and focus throughout the day, the most notorious of which is the mid-afternoon slump.

These fluctuations occur even if you are eating normally and not exercising. When you are trying to lose weight you may experience a more noticeable drop in both energy and the ability to concentrate on what you are doing for long periods of time.

Keto OS believes losing weight shouldn’t interfere with your productivity day to day. Their formula boosts energy and focus, enabling you to feel ready to tackle whatever your schedule has in store for you.

Improves Sleep Quality

Getting a good night’s sleep is incredibly important to our overall health.

Sleep is important to how our brain functions, including how nerve cells (neurons) communicate with each other. Sleep is also believed to play a role in the removal of toxins in the brain that build up during waking hours. (7)

Studies have shown the not getting adequate slumber time can decrease productivity, increase the chance of developing disease and also contribute to weight gain. (8)

Furthermore, lack of sleep can negatively affect mood and increase the likelihood of eating unhealthy snacks to boost energy levels. (9)

Usually when following a ‘ketogenic diet’, you must cut out carbohydrates to lose weight.

Carbohydrates facilitate the absorption of an amino acid known as l-tryptophan into the brain, which plays a role in the production of serotonin – a calming and sleep inducing neurotransmitter. (10)

Because of the elimination of carbohydrates in a regular ketogenic diet, followers often struggle to fall asleep.

Keto OS doesn’t require you to cut out anything from your diet to lose weight, enabling you to get a good night’s sleep and take advantage of ketogenic fat loss.

Ingredients

Beta Hydroxybutyrate (BHB)

BHB is simply the fancy name for the ketones contained in Keto OS.

BHB can come from two sources; either manufactured within the body, or by supplementation.

BHB made within the body is manufactured by the liver. It is a byproduct produced during the fat burning process and occurs when there is no carbohydrate (glucose) available for energy. (11)

Because the body needs a constant supply of energy the production of BHB and its role in creating fuel from fat is crucial to our survival. If we were unable to produce energy from fat stores, short term food restriction could have detrimental effects.

Taking a BHB (ketone) supplement is a great way to vastly increase the levels into the blood and enjoy the benefits of ketosis weight loss without having to undertake a ketogenic, low carb diet.

BHB supplementation has been clinically proven to increase fat oxidation and weight loss. (12)

L-Taurine

Taurine is an amino acid found in fish, dairy products and meat, as well as dietary supplements.

It is also found in the human body in our muscles, brain, eyes and heart. It is considered to be a ‘non-essential’ type of amino acid due to the fact the body can synthesise it on its own.

Taurine has antioxidant properties and is believed to help improve heart health. Normal taurine concentrations are also essential in the control of diabetes and its health consequences. (13,14)

For example, animal studies have discovered that sufficient taurine concentrations help to manage diabetes by lowering blood glucose levels and supporting insulin sensitivity. (15)

L-Leucine

L-leucine is an essential amino acid which cannot be produced by the human body. This means it must be consumed through the diet or supplements to ensure you are getting what you need.

L-leucine is found naturally in eggs, dairy, beans, soy products and meats. It has extensive health benefits and positive effects for weight loss.

It helps to maintain lean muscle mass, which is incredibly important for both the maintenance of the metabolism but also blood sugar levels. (16)

Studies show ingestion of leucine-enriched amino acids stimulates muscle protein synthesis to a similar extent in both young and elderly individuals. (17)

Inulin

Inulin is kind of soluble fiber present in thousands of plants, although Keto OS have chosen to extract theirs from chicory root.

It is similar to the effects of psyllium husk and other digestive boosters in that it supports the digestion and can help to lower cholesterol and blood glucose levels.

Soluble fibers such as inulin reduce LDL (“bad”) cholesterol. It interacts with absorption of dietary cholesterol and therefore can reduce the risk for heart and vascular related disease and metabolic syndrome. (18)

Furthermore, the carbohydrates contained within inulin cannot be broken down by our body and therefore will not cause insulin to be secreted or cause an increase in blood sugar. (19)

Caffeine

Caffeine is the most widely used legal stimulant drug in the world.

It is a chemical that affects the central nervous system and changes the way the brain and body work to create an boost of energy, alertness and focus. (20)

Caffeine wоrkѕ to increase the bоdу’s metabolic rate and ensures bоdу ѕtауѕ еnеrgizеd for lоngеr. (21)

Keto OS uses caffeine to give you the kick of energy required to to overcome any energy slumps caused by a change in lifestyle.

MCT Powder

MCT powder is a powdered form of medium-chain triglycerides, a kind of saturated fatty acid that is popular in an oil form, too.

As we have seen, the ketogenic diet is high in fat and low in carbohydrates, causing the body to have to switch to fat as a fuel source.

Most fats enter the liver slowly, whereas MCT fats can enter the liver rapidly and directly. This enables the liver to produce ketones quickly and more efficiently using MCT fats as the source. (22)

Therefore, consuming MCT fats gives the body an opportunity to rapidly produce ketone bodies as an energy source for both body and brain.

Side Effects

There are a few side effects to consider when using this product.

Many people experience the need to urinate more often as ketones have a diuretic effect. Therefore it is important to make sure you drink enough water when taking Keto OS.

Other possible side effects are tiredness, headaches, muscle aches and nausea.

Recommended Dosage

Dissolve one scoop or sachet into 12-16 oz of cold water and mix vigorously. You do not need to take Keto OS with food.

Summary

Keto OS is an unique supplement which aims to change your body’s preferred fuel source, eating away fat day by day without any drastic dietary changes.

The formula contains not only ketones, but also amino acids and fiber which have a range of health benefits outside of weight loss.

However, Keto OS is particularly expensive, $144 per month is not sustainable for most people.

That said, Keto OS will appeal to those who are interested in ketogenic weight loss but do not wish to restrict their diet completely.
