Keto Diet: How It Works And What It Burns

The keto diet is a low-carb, high-fat approach to weight loss that is widely popular but challenging to follow. It involves a metabolic state called ketosis, where the body burns fat for energy instead of glucose. Normally, the body uses carbohydrates from dietary sources like starches and sugars, which are broken down into glucose and used as fuel. However, when carb intake is very low, the body switches to burning fat, producing compounds called ketones, which become the main energy source. The keto diet typically consists of 70% to 80% fats, 10% to 20% proteins, and only 5% to 10% carbohydrates. This shift in metabolism is believed to aid weight loss, increase energy, and potentially treat chronic illnesses like epilepsy, type 2 diabetes, and heart disease.

Ketosis is a metabolic state where the body burns fat for energy instead of glucose

Ketosis is achieved by following a low-carb, high-protein diet, which is typically called a keto diet. The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates. To enter and stay in ketosis, you need to stay under 50 grams of carbohydrates per day. This is equivalent to around three slices of bread, two bananas, or one cup of pasta.

The keto diet has many possible benefits, including potential weight loss, increased energy, and the treatment of chronic illnesses. Research has shown that ketosis may have several health benefits, including weight loss, reduced hunger, and the treatment and management of diseases such as epilepsy, Alzheimer's disease, and type 2 diabetes.

However, the keto diet can be challenging to follow and may produce side effects such as ""keto" breath, constipation, and fatigue. It is also important to note that ketosis can become dangerous for people with diabetes when ketones build up, as it can lead to dehydration and a change in the chemical balance of the blood. Therefore, it is always recommended to consult a healthcare provider before starting any new diet, such as the keto diet, to ensure it is safe and suitable for your individual needs.

Ketogenic diets are high in fat and protein and low in carbohydrates

Ketogenic diets typically consist of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates. To enter and maintain ketosis, a person needs to stay under 50 grams of carbohydrates per day. This amount can vary depending on body size, with some people needing a more restricted diet to produce enough ketones. Ketosis usually takes two to four days to achieve, but it can take longer for some individuals.

The keto diet is often challenging to follow, as it requires a significant reduction in carbohydrate intake. However, it has been shown to be effective for weight loss and can provide other potential health benefits, such as increased energy and improved neurological conditions. Additionally, ketogenic diets may improve overall health and boost weight loss by increasing the body's fat-burning capabilities.

While the keto diet can be beneficial, it is important to note that it may also lead to side effects, such as "keto flu," constipation, and bad breath. It is always recommended to consult with a healthcare professional before starting any new diet, especially one as restrictive as the keto diet.

Ketosis can be achieved by eating fewer than 50 grams of carbohydrates per day

Ketosis is a metabolic state in which the body uses fat as its main fuel source instead of glucose. This process occurs when the body doesn't have enough carbohydrates to burn for energy. Typically, the body breaks down carbohydrates into glucose, which is then used as fuel. The liver stores the rest and releases it as needed.

When your carb intake is very low, these glucose stores are drained, and since your body doesn't have enough carbs to burn for energy, it burns fat instead. As your body breaks down fat, it produces a compound called ketones, which become your body and brain's main source of energy.

The keto diet is a popular weight loss program that promotes ketosis. In addition to helping you burn fat, ketosis can make you feel less hungry and help you keep muscle. For healthy people who are not pregnant, ketosis usually occurs after 3-4 days of eating fewer than 50 grams of carbohydrates per day. This amount of carbohydrates is equivalent to about three slices of bread, two bananas, or one cup of pasta.

To achieve ketosis, it is recommended to reduce your carb consumption to 50 grams or less per day. However, the exact carb limit can vary from person to person. In addition to reducing carb intake, increasing physical activity can also help induce ketosis. Exercise helps reduce the body's stores of glycogen, a form of glucose. Normally, eating carbs restores glycogen levels, but on a low-carb diet, these stores are not sufficiently replenished, encouraging the body to turn to fat as a source of fuel.

Intermittent fasting can also help achieve ketosis. This involves eating all your food within an 8-hour window and then fasting for the remaining 16 hours of a 24-hour period. Additionally, increasing your intake of healthy fats, such as avocados, avocado oil, and fatty fish like salmon, can help induce ketosis.

Ketosis has several potential health benefits, including weight loss, increased energy, and the treatment of chronic illnesses such as epilepsy, Alzheimer's disease, and type 2 diabetes. However, it is important to note that the keto diet can be challenging to follow and may produce side effects such as "keto" breath and constipation.

Ketosis may cause side effects such as keto flu, bad breath, and constipation

Ketosis is a metabolic state in which the body burns fat for energy instead of glucose. While it can be beneficial for weight loss, increased energy, and treating chronic illnesses, it can also lead to some side effects. One of the most well-known is the "keto flu," which includes symptoms such as an upset stomach, headache, fatigue, and sugar cravings. These symptoms typically arise within the first few days or weeks of starting a ketogenic diet and can range from mild to severe. They are believed to be caused by the body's withdrawal from carbohydrates and the subsequent shift to burning fat for energy.

Another common side effect of ketosis is bad breath, often referred to as "keto breath." This occurs when the body reaches a state of nutritional ketosis, and the liver produces a ketone called acetone. Acetone enters the lungs and is exhaled, resulting in a distinctive odour. While this side effect can be unpleasant for those experiencing it and those around them, it is a sign that the body has reached a fat-burning state.

Additionally, constipation is a known side effect of ketosis. This is often due to the reduction in fluid intake and the decrease in insulin levels that occurs during ketosis. However, this can be managed by increasing water and electrolyte intake, particularly sodium and magnesium, which can help with constipation and other keto flu symptoms.

While ketosis can lead to these side effects, they are usually temporary and can be alleviated by making sure to stay hydrated, increasing salt and water intake, and gradually reducing carbohydrate consumption.

Ketosis can be measured through blood, breath, or urine tests

The keto diet is a low-carb, high-fat, and moderate-protein diet. It is a natural metabolic state that your body enters when following a very low-carb diet or during starvation. When on a keto diet, your body will enter a state of ketosis, where it will burn fat for fuel. Ketosis can be measured through blood, breath, or urine tests.

Measuring Ketosis Through Urine Tests

Urine strips are a cheap and convenient way to test for ketosis. They are typically used by people with type 1 diabetes to determine if they are at immediate risk of diabetic ketoacidosis, a potentially life-threatening condition. Urine strips can be purchased over-the-counter at pharmacies and supermarkets, as well as online. They are relatively inexpensive and typically expire within three to six months after opening. To use a urine strip, you collect a urine sample in a small container, immerse the strip into the sample, and then compare the colour of the strip to the colour chart on the packaging. The darker the colour, the higher your ketone levels. However, it is important to note that urine ketone testing is not as accurate as blood ketone testing, as the levels of ketones in the urine will usually only reflect the level from a few hours previously. Additionally, the concentration of ketones in urine can be influenced by external factors such as hydration.

Measuring Ketosis Through Blood Tests

Ketone blood meters are a reliable and accurate way to measure ketone levels in the body. They are originally designed for people with type 1 diabetes but are also used by those following a ketogenic diet. Blood strips can be found at most places that carry urine strips, but a meter is needed to read the blood strips. Blood strips are more expensive than urine strips, costing around $1 per strip, but they last longer, with a typical expiry date of 12-18 months. To use a blood ketone meter, you load the lancet with a needle, insert a blood ketone strip, prick your finger to draw blood, and then let the strip come in contact with the blood. A preferable blood level of ketones for dietary ketosis is 0.5-3.0 mmol/L (9-54 mcg/dl).

Measuring Ketosis Through Breath Tests

Breath tests for ketosis are less common but can be useful for those who are uncomfortable with blood tests. One such meter is the Biosense Ketone Breath Meter, which can provide a fairly accurate approximation of your blood ketone levels.
