MCT oil can help control the hormones responsible for hunger, specifically peptide YY and leptin. Controlling these hormones can reduce the urge to overeat, making sticking to your low-calorie diet much easier.
Most fats do not have much of an impact on your metabolic rate. Their thermic effect is very low, between 0 to 5%, which means digesting fat takes very little energy. However, because of how MCTs are digested, they increase your metabolism more than LCTs, and that can enhance weight loss.
MCTs are also lower in calories than regular fats. Where most fats contain around nine calories per gram, MCTs weigh in at eight calories per gram. This is a small saving but, if you replace some of your normal LCT fats with MCTs, you will save yourself a few calories without eating less, and that can help contribute toward fat loss.
As well as helping you lose weight, Onnit MCT oil may help you lose fat from your abdomen. Abdominal or belly fat is closely linked to a host of medical problems, including diabetes and heart disease. Using MCT oil appears to preferentially target belly fat, which is good news for both your appearance and your long-term health.
✅ Rapidly available source of energy – under normal circumstances, your body likes to use glucose for energy. This is especially true during exercise. However, glucose is a fast-acting fuel, and if you consume more than you need, any surplus is quickly and easily turned into fat. Glucose, which is derived from carbs, is also off the menu during the ketogenic diet.
Because MCT oil travels straight from your stomach to your liver, it is digested very quickly, which means it provides an immediate source of energy. In addition, unlike unused glucose, excess MCTs are not easily converted to and stored as body fat. Instead, they are mostly converted to ketones, and unused ketones are excreted via the urinary system. In other words, you pee them out!
As an added benefit, MCTs may also help increase exercise duration and performance. When your body uses carbs for fuel, your muscles produce lactic acid – the stuff that makes your muscles burn during a tough workout. Using MCTs for energy instead of carbs means less lactic acid, which could help you exercise harder and longer.
MCTs are also a great source of energy for your brain. When you eat carbs, your blood glucose levels rise and then fall, which can lead to things like brain fog and sugar cravings. In contrast, MCT oil provides a more stable source of energy which should improve brain function and enhance productivity.
Onnit MCT oil users report an increase in both mental and physical energy, with none of the peaks and troughs usually associated with using glucose for energy.
✅ Better gut and digestive health – your digestive system is the center of your body, responsible for every aspect of your health, from weight loss to disease immunity. Your digestive health is primarily determined by the bacteria in your gut, which can be helpful or harmful.
MCT oil increases good gut bacteria while decreasing levels of bad gut bacteria. This enhances general digestive health and, more specifically, enhances the health of your gut lining. A healthier gut lining makes it easier for your body to absorb and utilize nutrients. Better nutrient absorption means a better functioning body and immune system, as well as fewer digestive upsets, less bloating, and a reduced risk of weight gain.
✅ Better mental health – your brain is an amazing organ, but it’s also susceptible to a wide range of problems, from mood swings to depression to serious medical conditions like Alzheimer’s disease, Parkinson’s disease, epilepsy, and autism. Numerous studies have revealed that a low carb, low sugar diet supplemented with MCT oil can help with all aspects of mental health, including the control of diseases affecting the brain.
✅ Reduced risk of heart disease – heart disease is the leading cause of death in the developed Western world. Heart disease is characterized by partially or entirely blocked coronary arteries, which are the vessels that keep your heart supplied with blood. An unhealthy diet, being sedentary, smoking, and genetics can all increase your risk of developing heart disease.
However, MCT supplements like Onnit MCT oil have been shown to reduce many of the risk factors linked to heart disease, including increasing good cholesterol and reducing bad cholesterol. Losing weight is also a significant factor in reducing the risk of heart disease, and MCT oil has been revealed to be an effective weight-loss intervention – discussed above. MCT also has a pronounced anti-inflammatory effect. Inflammation increases the risk of heart disease.
How to use Onnit MCT oil

To get the most form Onnit MCT oil, it is important that you use it properly. According to Onnit, users should take one tablespoon (15 mL) one to four times daily.

Side effects
Onnit MCT oil is a natural supplement that offers a wide range of benefits, not just for keto dieters, but for anyone interested in improving their health. However, like any supplement, some users may experience unwanted side effects. Those side effects include:
❗️ Stomach upset – despite being a very pure product, Onnit MCT oil can cause gas, bloating, and diarrhea in some users. This is usually the result of consuming too much MCT oil too soon. If you experience any form of gastric upset, reduce your intake, and then reintroduce gradually after that. Start off with half a tablespoon twice per day and increase from there.
❗️ Fat gain – Onnit MCT oil can help you lose weight, but it’s important to understand that it still contains calories and a calorie excess can lead to fat gain. MCT oil contains 10% fewer calories than regular fat and is less likely to be converted to and stored as body fat. However, if consumed in excess, it could still contribute to weight gain. Avoid this problem by decreasing your intake of non-MCT fats and not exceeding the recommended daily dose.
❗️ Non-alcoholic fatty liver disease – MCT oils are processed in your liver. This should not present a problem if you have a healthy liver and do not consume excessive amounts. However, if you have an underlying liver condition or consume too much MCT oil for an extended period of time, you may increase your risk of developing non-alcoholic liver disease. Do not exceed the recommended dose and, if you have a history of liver disease, speak to your doctor before using Onnit MCT oil or any other MCT oil product.
