The ketogenic diet, commonly known as the keto diet, is a low-carb, high-fat diet that aims to burn fat for energy instead of glucose. This shift in metabolism can be challenging to maintain, leading to the popularity of keto supplements. Keto Burn, for example, contains bioavailable BHB salts, amino acids, and L-citrulline to support nutritional ketosis, energy production, and appetite control. Additionally, keto gummies, pills, and powders are marketed to help keep the body in ketosis. These products often contain medium-chain triglycerides (MCTs) and exogenous ketones, which provide energy and facilitate the body's use of ketones. While these supplements claim to aid weight loss and enhance energy, it's important to consult a healthcare provider and maintain a balanced diet with whole, single-ingredient foods like meat, fish, eggs, nuts, and low-carb vegetables.

What You'll Learn
Ketogenic diets are low-carb, high-fat
There are several versions of the ketogenic diet, including the Standard Ketogenic Diet (SKD), which is a very low-carb, moderate-protein, and high-fat diet. The Cyclical Ketogenic Diet (CKD) involves periods of higher carb refeeds, such as 5 ketogenic days followed by 2 high-carb days. The ketogenic diet has been shown to be effective for weight loss and can also provide numerous health benefits. For example, it can lower blood sugar and insulin levels, improve insulin sensitivity, and reduce the risk of certain diseases like diabetes, cancer, epilepsy, and Alzheimer's.
When starting a ketogenic diet, it's important to ease into it and ensure you're eating until you're full, without restricting calories too much. It's also crucial to pay attention to your body's water and mineral balance, as the keto diet can affect these. Eating a variety of whole, single-ingredient foods is essential, including meat, fish, eggs, butter, nuts, healthy oils, avocados, and low-carb vegetables.
While the ketogenic diet has many potential benefits, there are also some risks to consider. For example, the high saturated fat content and lack of fiber can increase the risk of heart disease. Rapid weight loss on the keto diet can lead to muscle loss, and the low-carb nature of the diet can potentially cause cognitive decline. It is important to consult a healthcare practitioner before starting a new diet.

Ketosis: Burning fat for energy
Ketosis is a metabolic state where the body burns fat for energy instead of carbohydrates. Typically, carbohydrates in your diet provide most of the fuel your body needs. However, when you're in ketosis, your body becomes incredibly efficient at burning fat for energy. This is because, with a lack of carbohydrates, your body has to turn to an alternative fuel source.
The keto diet is a low-carb, high-fat diet that can cause your body to enter ketosis. This is because the reduction in carbohydrates means your body has to burn fat for fuel instead. The keto diet typically contains 70% fat, 20% protein, and only 10% carbohydrates. The high-fat content of the keto diet means that the body has plenty of fat to burn for energy.
To enter ketosis, you need to eat between 20 and 50 grams of carbohydrates each day. It usually takes around two to four days to enter ketosis, but this can vary depending on several factors. These include your carbohydrate, fat, and protein intake, physical activity level, metabolism, sleep health, and stress level. If you eat a high-carb diet before starting keto, it may take longer to reach ketosis as your body needs to exhaust its glucose stores first. Intermittent fasting can help speed up the process, as it involves eating all your food within an eight-hour window and fasting for the remaining 16 hours.
The keto diet has several potential benefits, including weight loss, increased energy, and the treatment of chronic illness. However, it can be challenging to follow and may cause side effects such as "keto breath" and constipation. It's important to note that keto supplements like gummies, pills, or powders don't put you in ketosis but can help keep your body in that state.

Foods to eat: Meat, fish, eggs, nuts
Meat, fish, eggs, and nuts are all foods that can be included in a keto diet.
Meat is considered a staple food on the keto diet. Poultry, for example, contains no carbs and is rich in B vitamins and minerals. It is also a great source of high-quality protein, which may help preserve muscle mass during a very low-carb diet. Grass-fed meat is preferable, as it has more omega-3 fats and conjugated linoleic acid (CLA) than meat from grain-fed animals.
Fish and seafood are excellent sources of omega-3 healthy fats, which may reduce inflammation and lower the risk of cancer, arthritis, and neurodegenerative diseases. Fatty fish like salmon, sardines, and mackerel are particularly high in omega-3 fats and may help manage blood sugar levels and lower insulin levels in people with diabetes. Frequent fish intake is also linked to improved brain health and a decreased risk of disease.
Eggs are another staple food in keto diets. They have been shown to trigger hormones that increase feelings of fullness. It is important to eat whole eggs, as most of an egg's nutrients are found in the yolk, including antioxidants that protect eye health.
Nuts are a great source of healthy fats, making them ideal for a low-carb keto diet. They are also rich in vitamins, minerals, fiber, and antioxidants, making them a well-rounded addition to your diet. Some of the best nuts to include are peanuts, pecans, almonds, and pistachios, which are high in healthy fats and low in carbs.

Foods to avoid: Fruit, sugar, beans, high-carb veggies
A ketogenic, or keto, diet is a high-fat, low-carb way of eating that shifts your body into a fat-burning state called ketosis. When your body reaches ketosis, it uses fat reserves for energy instead of carbohydrates.
Fruits
Fruits are not entirely off-limits on a keto diet, but most are high in sugar and carbs, so they should be avoided or at least consumed in moderation. Fruits have been selectively bred and, in some cases, genetically modified to be bigger, sweeter, and brighter, which means they contain more sugar.
Sugar
Sugar is not a keto-friendly ingredient. Excessive sugar intake has been linked to a higher risk of obesity, type 2 diabetes, heart disease, dental problems, metabolic syndrome, and inflammation. Sugar cravings can be hard to resist, especially when triggered by commercials or the sight and smell of carbohydrate-heavy meals. However, sugar cravings will likely subside within a few days of starting a keto diet.
Beans
While beans are rich in fibre, healthy fats, and protein, most types are too high in carbs to be suitable for a keto diet. A half-cup serving of beans can contain between 12 and 25 grams of net carbs. Black soybeans are a good low-carb alternative to traditional beans like pinto and black beans. Hummus, made from chickpeas, tahini, and olive oil, can also be consumed in small amounts on a keto diet.
High-carb vegetables
Although vegetables are an essential part of a keto diet, some contain too many carbs and should be avoided or consumed in moderation. Starchy vegetables, in particular, tend to have a high carbohydrate content.

Supplements: Keto gummies, pills, powders
The ketogenic diet is a low-carb, high-fat diet that causes weight loss and provides numerous health benefits. However, getting into and staying in ketosis can be challenging. This is where keto supplements come in—they claim to increase ketone levels, help achieve ketosis faster, and ultimately lead to weight loss.
Keto Gummies
Keto gummies are made with exogenous ketones, which are ketones obtained from an outside source. They are meant to supplement the ketones your body produces through the food you eat. While keto gummies may help the process of ketosis, they cannot put you into ketosis. Additionally, they may not help with weight loss. It is important to note that the effectiveness of keto gummies has not been scientifically proven, and they can be expensive. Furthermore, for those with Type 2 diabetes, high blood pressure, or kidney issues, caution should be exercised as the keto diet and keto gummies can lower blood sugar levels and cause dehydration.
Keto Pills
Keto pills claim to help sustain ketosis and weight loss. However, there is limited research on the efficacy of these supplements. One small study found that obese individuals on a low-calorie ketogenic diet who took a BHB salt supplement experienced enhanced ketosis, but it did not boost weight loss compared to those on the keto diet without the supplement.
Keto Powders
Like keto pills, keto powders typically contain some form of BHB. They may also include electrolytes to aid in hydration and ketosis maintenance. However, the Food and Drug Administration does not approve dietary supplements, so there is a risk of contamination or mislabelling with keto powder products.
Overall, while keto gummies, pills, and powders claim to aid in ketosis and weight loss, there is limited scientific evidence to support these claims. It is always recommended to consult with a healthcare professional before starting any new supplement or diet regimen.
