Keto Weight Loss: When Does It Start?

The ketogenic, or keto, diet is a low-carb, high-fat way of eating that has been adopted by many looking to lose weight and improve health. The keto diet helps to significantly reduce weight within a relatively short period of time. Typically, people will start to lose weight straight away when they start the keto diet, with anywhere between 2-10 lbs of weight loss expected after the first week. However, this initial weight loss is not due to losing fat but rather water, as the body expels water bound to glycogen stores. After the first week, weight loss will continue at a steadier rate of 1-2 lbs per week.

Weight loss is mostly water weight initially

When starting the keto diet, it's common to experience rapid weight loss in the first week. This is mostly due to a loss of water weight, as your body releases and excretes the water that was bound to glycogen stores in your muscles and liver. The larger your body, the more water weight you're likely to lose initially. This can result in a weight loss of anywhere from 1 pound (0.5 kg) to 10 or more pounds (5 kg) within the first week.

The keto diet is a high-fat, low-carb diet, which typically involves limiting your carb intake to 50 grams or fewer per day of total carbs, or 20-25 grams or fewer of net carbs (total carbs minus fiber). When you restrict carbs on keto, your body rapidly burns through glycogen, and after your glycogen stores are depleted, you shift to burning fat.

The shift from burning glycogen to burning fat, known as ketosis, usually takes less than a week, but it can take longer for some people. During this transition period, many people notice dramatic weight loss, which is mostly due to changes in water weight. The glycogen stored in your muscles and liver is bound with water, typically at a ratio of 3 grams of water for each gram of glycogen. When you burn through these stored carbs, the water is excreted in your urine or sweat.

While this initial weight loss is mostly water weight, it's important to note that once you enter ketosis, it becomes much easier to utilize your own stored fat for energy, which is one of the reasons why the keto diet is advantageous for weight loss. In the short and medium term, weight loss on keto usually occurs at a steadier pace of about 1-2 pounds per week. This is the time when your body is getting fat-adapted and actually burning fat, so the weight loss is likely to be more fat than water.

A safe rate of weight loss is between one to two pounds per week

The keto diet is a low-carb, high-fat diet. When starting the keto diet, people often experience rapid weight loss in the first week or two, which is mostly due to a loss of water weight. After this initial period, weight loss typically occurs at a slower, more steady pace of about one to two pounds per week. This rate of weight loss is considered safe by the National Institutes of Health.

During the first week of keto, the body burns through glycogen stores, which are bound to water. As a result, people often see a quick drop in weight on the scale, which can be anywhere from a few pounds to as much as ten pounds. However, this initial weight loss is not a result of fat loss. It is only when the body enters ketosis, typically within a week, that it starts burning fat for energy.

Once the body is in ketosis, weight loss will likely slow down, but it will be more fat than water. On keto, people strictly limit their carb intake, which can be challenging to maintain. It is important to plan meals and snacks in advance to stay on track. Additionally, focusing on carbs and having an accountability partner can help with sticking to the diet.

While the keto diet can lead to rapid weight loss, it is not meant to be a long-term solution. It is important to consult with a healthcare professional before starting any new diet, as keto may not be suitable for everyone. Overall, a safe and healthy rate of weight loss is about one to two pounds per week, which can be achieved through the keto diet with proper planning and accountability.

The keto diet is not meant to be done long-term

The keto diet is a popular weight-loss strategy, but it is not intended to be a long-term solution. While it can lead to rapid weight loss, there are several reasons why it is not sustainable or safe for extended periods.

Firstly, the keto diet is highly restrictive and difficult to follow. It involves drastically reducing carbohydrate intake to around 20-50 grams per day, which means cutting out many foods such as fruits, dairy, starchy vegetables, whole grains, and legumes. This can lead to nutrient deficiencies over time, as fruits and vegetables are excellent sources of vitamins and minerals. The diet also requires a high intake of fat, with up to 90% of daily calories coming from fat. This includes saturated fats from oils, lard, butter, and cocoa butter, which are encouraged in high amounts. Such a high-fat diet may increase the risk of heart disease and other health issues.

Secondly, the keto diet can be challenging to stick to due to its restrictive nature. It may not be compatible with everyone's lifestyle or food preferences, and it can be difficult to maintain the required level of restriction. Relaxing the rules or transitioning to a more relaxed form of keto can lead to weight regain, creating a yo-yo pattern that is frustrating and linked to a higher risk of early death.

Thirdly, the long-term effects of the keto diet are not yet fully understood. While it can lead to rapid weight loss, there may be negative consequences that are not yet known. Some studies suggest potential problems, such as metabolic dysfunction and an increased risk of certain health conditions. Additionally, the keto diet may affect athletic performance, as the body is in a more acidic state during ketosis, which may limit its ability to perform at peak levels.

Finally, the keto diet can be unsafe for individuals with certain health conditions, such as kidney disease. It is important for anyone considering the keto diet to consult with a doctor and a registered dietitian to ensure it is safe for their individual circumstances. Overall, while the keto diet may be effective for short-term weight loss, it is not designed or recommended as a long-term solution due to its restrictiveness, potential health risks, and lack of long-term research.

The keto diet is a high-fat, low-carb diet

The ketogenic diet, or keto for short, is a high-fat, low-carbohydrate diet. It typically limits carbohydrates to 20-50 grams per day, with some people aiming for even fewer than 20 grams. This is a very low amount of carbohydrates, as some people on a standard diet may consume 20 grams of carbs in a single meal.

On the keto diet, fat becomes the primary source of fuel for the body instead of carbohydrates. This shift in metabolic state is called ketosis. Ketosis burns through the body's glycogen stores, which are bound with water, leading to a rapid loss of water weight when starting the keto diet. This can result in frequent urination and increased thirst. While this initial weight loss is mostly water weight, some studies suggest that the keto diet may be advantageous for continued weight loss.

The keto diet is high in fat, with some sources recommending 165 grams of fat in a 2,000-calorie diet. This fat can come from animal proteins such as meat and poultry, as well as fatty fish like salmon, sardines, and mackerel. Cheese is also commonly consumed on the keto diet, as are eggs. Some healthy unsaturated fats that are allowed on the keto diet include nuts, seeds, avocados, tofu, and olive oil. However, the keto diet also encourages the consumption of saturated fats, such as oils, lard, butter, and cocoa butter.

The keto diet is quite restrictive and may be challenging to follow, especially when eating at restaurants. It is also associated with several risks, including an increase in "bad" LDL cholesterol, nutrient deficiency, liver problems, kidney problems, and constipation. Therefore, it is important to consult a doctor and a registered dietitian before starting the keto diet.

It can take as little as a week for your body to enter ketosis

The ketogenic diet is a low-carb, high-fat diet that has gained popularity for its weight-loss benefits. While the diet was originally devised to help treat epilepsy, many people are turning to it to lose weight.

When you start the keto diet, it can take as little as a week for your body to enter ketosis, a metabolic state where your body uses ketones, broken down from dietary or stored body fat, as its primary source of fuel. This shift from burning glycogen to burning fat usually takes less than a week and can result in dramatic weight loss during the transition.

During the first week of keto, many people experience a rapid drop in weight, often attributed to the loss of water weight. This is because carbs need water to stay in your body, and when you lower your carb intake, your body releases a lot of water weight. For example, each gram of glycogen, the stored form of glucose, is stored with 2 to 3 grams of water. As your body burns through its glycogen reserves, the water that was bound to it is excreted through urine or sweat.

However, it's important to note that this initial weight loss is not fat loss. The fat-burning benefits of ketosis typically kick in after the first week or two, leading to steadier weight loss. At this point, your body is getting fat-adapted, and you'll be burning fat instead of carbs for energy. A safe average loss is around one to two pounds per week.

While keto can be an effective way to lose weight, it's not meant to be a long-term diet. It's always a good idea to consult your healthcare provider before starting any new diet, especially one as restrictive as keto.
