Keto Diet: How Does It Work?

The keto diet is a low-carb, high-fat diet that has gained popularity for its ability to induce quick weight loss. The diet works by changing the way the body burns energy, shifting from carbohydrates as the primary fuel source to dietary fat and the body's fat storage, which produces ketone bodies. This state, known as ketosis, can be challenging to achieve and maintain due to the restrictive nature of the diet. While the keto diet has been shown to be effective for weight loss and managing certain health conditions, it also has potential drawbacks and risks, including nutrient deficiencies, dehydration, kidney problems, and increased cholesterol levels.

The keto diet changes the way your body burns energy

Instead, the body uses ketone bodies, a type of fuel that the liver produces from stored fat. This process is called ketosis, and it is the state in which the body burns fat for energy instead of glucose. Ketosis can be reached in a few days to a week or longer, depending on factors such as physical activity level and previous diet composition.

On a keto diet, the body draws its energy from dietary fat and the body's fat storage, which produces ketone bodies. The keto diet, therefore, changes the way the body burns energy by shifting the body's dominant fuel source from glucose to ketones.

The keto diet helps people lose weight

Ketosis is a metabolic state where the body burns fat for energy instead of glucose. The keto diet is high in fat, moderate in protein, and low in carbohydrates. The standard keto diet consists of 70% to 80% fats, 10% to 20% proteins, and 5% to 10% carbohydrates. To maintain ketosis, one needs to keep their daily carb intake to around 20 to 50 grams. This can be challenging as it means cutting out bread, cereal, grains, and significantly reducing fruit and vegetable intake.

The keto diet also leads to weight loss because it is a very low-calorie diet. By eliminating food groups and reducing calorie intake, people lose weight. However, this can also lead to nutrient deficiencies, and it is important to ensure adequate nutrient intake while on the keto diet.

While the keto diet can be effective for weight loss, it is not without its drawbacks. It is a very strict and restrictive diet that can be challenging to stick to. It can also lead to side effects such as "keto flu," which includes symptoms like nausea, constipation, headaches, and fatigue. It is important to consult a healthcare professional before starting the keto diet to ensure it is safe and appropriate for your individual needs.

The keto diet is strict and restrictive

The keto diet is strict in that it requires careful monitoring of food intake to ensure the body achieves and maintains ketosis. This metabolic state, ketosis, is when the body burns fat for energy instead of glucose. Even small amounts of carbohydrates or excess protein can prevent the body from reaching and sustaining ketosis. Therefore, the keto diet is restrictive in terms of food choices and requires dedication to tracking food intake.

The high-fat nature of the keto diet can be challenging for some people. The diet includes foods such as oils, butter, avocado, nuts, red meat, fatty fish, cheese, and eggs. While these foods can be enjoyable, the diet limits or eliminates legumes, fruits, starches, and other favourite foods. The keto diet can also be more expensive than a typical diet due to the cost of these foods.

In addition to the restricted food choices, the keto diet may also lead to social restrictions. Eating out or attending social gatherings where food is involved can be challenging when adhering to the keto diet. It may require asking for menu modifications or explaining one's dietary restrictions, which some may find awkward or uncomfortable.

Furthermore, the keto diet can be difficult to sustain due to its stringent food restrictions. Many people may find it hard to stick to the diet long-term, and there are concerns about the potential for yo-yo dieting if the diet is not maintained consistently. The keto diet is intended to be a short-term solution for weight loss, followed by the adoption of healthier eating habits to maintain results.

The keto diet can cause side effects like 'keto flu'

The keto diet can cause side effects like keto flu.

The keto diet is a very strict, high-fat, low-carbohydrate diet. While it is considered safe for most people, it can cause some unpleasant side effects, known as the "keto flu". The keto flu is a collection of symptoms experienced by some people when they first start the keto diet. This includes headache, brain fog, fatigue, irritability, nausea, difficulty sleeping, and constipation. These symptoms are caused by the body adapting to a new diet consisting of very few carbohydrates.

The keto flu is not a recognised medical condition, and its causes are not well understood. It may be related to a detox factor, carb withdrawal, an immunologic reaction, or a change in the gut microbiome. The symptoms of keto flu can vary from person to person and can range from mild to severe. For some people, the transition to a ketogenic diet may be especially difficult, while others may not experience any side effects at all.

The good news is that the symptoms of keto flu are usually temporary and will disappear within a few days to a few weeks as the body adapts to the new diet. There are also some things you can do to alleviate the symptoms:

• Increase your salt and water intake: Losing salt and water is responsible for many keto flu symptoms, so increasing your intake can help reduce them.
• Eat more fat: Eating more fat can help reduce symptoms by ensuring you're not hungry and have ample energy.
• Take it slow: If you're still feeling off after increasing your water, salt, and fat intake, try slowing down the transition to a ketogenic diet by consuming slightly more carbs.
• Avoid strenuous exercise: Trying to do too much in the early stages of the keto diet can worsen keto flu symptoms.
• Get plenty of rest: Fatigue and irritability are common symptoms of keto flu, so make sure to get enough sleep.

While the keto flu can be unpleasant, it's important to remember that it's not contagious or dangerous. By taking some simple steps to alleviate the symptoms and giving your body time to adjust, you can successfully get through the keto flu and experience the benefits of the keto diet.

The keto diet can be costly

One way to save money is to buy in bulk. Purchasing nuts, seeds, shredded coconut, and cooking oils in larger quantities can help reduce expenses. Additionally, buying meat, vegetables, and avocados in bulk and freezing them for later use can also be cost-effective. Shopping for seasonal and locally grown vegetables can also help reduce costs, as they tend to be less expensive than out-of-season produce.

Another strategy is to opt for cheaper protein sources such as eggs, canned fish, and cheaper cuts of meat. Planning meals in advance and preparing simple meals with boiled eggs, shredded chicken, and simple salads can also help stick to a budget. It is recommended to skip the packaged keto-friendly foods, as they tend to be expensive and highly processed.

While the keto diet may require a higher upfront cost for ingredients like almond flour and erythritol, these ingredients last a long time and can be used in multiple recipes. Additionally, cooking at home instead of eating out can result in significant savings.

It is worth noting that the keto diet is not just about saving money but also about investing in one's health. The diet may lead to health improvements, which can reduce healthcare costs in the long run. However, it is always recommended to consult a healthcare professional before starting any new diet, especially one as strict as keto.
