Keto Weight Loss: How Much Can You Lose In 2 Weeks?

The ketogenic diet, commonly referred to as the keto diet, is a low-carb, high-fat diet that encourages the body to enter a state of ketosis. In this metabolic state, the body burns fat for fuel instead of glucose, which can lead to rapid weight loss. Weight loss on keto varies from person to person, but generally, if you maintain a daily caloric deficit of around 500-700 calories, you can expect noticeable weight loss after anywhere from 10 to 21 days. However, it is important to understand that many of the early pounds lost will be water weight. After the first week or two, the weight loss rate may slow down as your body adapts to the diet. According to some sources, the average weight loss after the first week of keto is between 2-10 pounds, while others state that a safe average loss is around one to two pounds per week. One person on Reddit reported losing 13 pounds in two weeks.

Weight loss varies depending on factors like starting weight, body composition, and activity levels

The keto diet is a low-carb, high-fat diet that encourages the body to enter a state of ketosis, where fat is burned for energy instead of glucose. This metabolic state can lead to rapid weight loss as the body starts to use stored fat for energy, reducing body fat. However, it's important to note that weight loss is not linear and can vary from person to person.

Generally, if you maintain a daily caloric deficit of around 500-700 calories, noticeable weight loss can be expected after 10 to 21 days. Initial weight loss on the keto diet is often water weight, and after the first week or two, the weight loss rate may slow down as the body adapts to the diet.

Larger individuals tend to lose more water weight when starting the keto diet. Therefore, it is unlikely that the initial weight loss is due to fat loss. After the first week, weight loss usually continues at a steadier pace of about 1-2 pounds per week. This is also when the body enters ketosis and starts burning fat, which means you're losing fat at this stage.

According to studies, most people experience peak weight loss around the five-month mark. Dedication to the keto lifestyle can result in weight loss of up to 30 kilograms (66 pounds) by this point. Most doctors agree that losing about one to two pounds per week is sustainable and healthy. As you get closer to your ideal body weight, your body adapts, leading to a slowdown in weight loss progress.

It's important to remember that even if the scale doesn't show significant changes, your body composition may still be changing, and you could be losing fat. Additionally, non-scale victories (NSVs) such as improved energy levels, better sleep, enhanced mental clarity, reduced inflammation, and better skin health are also important measures of success on the keto diet.

Weight loss is not linear, and some may see results sooner

Weight loss on the keto diet varies from person to person and is dependent on several factors, including size, water retention, metabolism, diet adherence, and health conditions. While the keto diet is known for its ability to induce rapid weight loss, it is important to understand that this is not a linear process, and results may vary. Some individuals may experience weight loss sooner than others, while others may take a few weeks to see noticeable changes.

During the initial phase of the keto diet, the weight loss observed is primarily due to the depletion of water weight. Carbohydrates bind to water in the body, and when carb intake is restricted, the body eliminates this stored water, resulting in a rapid drop in weight. This water weight loss can range from 2 to 10 pounds during the first week of keto. However, it is important to note that this is not indicative of fat loss.

After the initial water weight loss, the rate of weight loss typically slows down to a steadier pace. At this stage, the body enters ketosis, a metabolic state where fat becomes the primary source of fuel. This transition from burning glycogen to burning fat may take a few days to a week. During this period, individuals may experience a reduction in cravings and increased energy levels. The weight loss during this phase is more likely to be from fat loss and can be sustained over a longer period.

While some people may experience rapid weight loss in the first few weeks, it is not uncommon for weight loss to slow down or plateau after the initial phase. This is because, as your body adapts to the diet and loses weight, it becomes more challenging to continue losing weight at the same rate. Additionally, as you get closer to your ideal body weight, your body begins to adjust, leading to a slowdown in weight loss.

It is important to remember that the keto diet is not just about weight loss. Non-scale victories, such as improved energy levels, better sleep, enhanced mental clarity, reduced inflammation, and better skin health, are also essential measures of success. These benefits may have a significant impact on overall health and well-being, even if they are not directly related to weight loss.

Initial weight loss is often water weight

When starting the keto diet, people often experience rapid weight loss in the first week. This is mostly due to a loss of water weight, which is encouraged by the diet's low-carb, high-fat strategy. Carbohydrates require water to stay in the body, and when you lower your carb intake, your body releases a lot of water weight. This is because glucose is stored as glycogen in your muscles, and glycogen binds to water. For each gram of glycogen stored in your body, it has 2-3 grams of water attached.

When you start the keto diet, your body will burn through its glycogen reserves before using fat. Once it runs out of glycogen, the water that was needed to store it gets eliminated. This loss of excess water is what causes the sudden and dramatic weight loss in the first week of the keto diet. Although this is not fat loss, it does mark the transition of your body into ketosis, which is when your body starts to burn fat for energy instead of glucose.

After the first week, your weight loss will not continue at the same pace. Instead, you can expect to lose a steady amount of between 1-2 lbs on average per week, which adds up to a significant amount over three months. After the first week, once you've used up your glycogen stores, your body will move into ketosis, and you'll begin to burn fat. Although the rate of weight loss may slow down, this is when you'll really start to notice a difference in your body.

Weight loss may slow as the body adapts to the diet

Weight Loss May Slow as the Body Adapts to the Keto Diet

While the keto diet can lead to rapid weight loss in the first week, this pace is unlikely to continue. After the initial period, the rate of weight loss may slow down as your body adapts to the diet. This is because the initial weight loss is mainly due to a loss of water weight, not fat.

During the first week of the keto diet, the body uses up all its glycogen stores for fuel before it starts burning fat. Glycogen binds to water, so when these stores are depleted, the water attached to it is eliminated from the body. This leads to a sudden and dramatic weight loss. However, this is not fat loss.

After the first week, you can expect to lose a steadier amount of weight, averaging 1-2 pounds per week. This is the time when your body is getting fat-adapted and switching from burning carbs to burning fat. While the rate of weight loss may slow down, this is when you will really start to notice a difference in your body. You will gradually become leaner and your body will start to change shape.

How to Keep Losing Weight

Even though weight loss may slow, there are some things you can do to keep the weight loss going:

• Calculate your macros: Figure out your personal keto macros using a keto calculator. This will give you a nutritional target based on your body composition, making it easier to enter and stay in ketosis.
• Increase physical activity: While exercise is not necessary for weight loss on keto, it can help burn more calories, build muscle, and improve your metabolic health.
• Adjust your activity level: As you lose weight, your physical activities may become less challenging. Be sure to increase the intensity of your workouts to meet your new fitness level.
• Recalculate your macros: After a few months on the keto diet, you may need to recalculate your macro amounts as your body composition and activity levels change.
• Focus on non-scale victories: Besides weight loss, the keto diet can bring other health improvements, such as increased energy, better sleep, reduced inflammation, and improved skin health.

The keto diet is not suitable for everyone

Firstly, the keto diet is not recommended for pregnant or breastfeeding women. This is because cutting out entire food groups can make it difficult to obtain the necessary nutrients for a healthy pregnancy and breastfeeding journey. For instance, fruits, vegetables, and whole grains are essential sources of folate, B vitamins, and choline, which are all vital for a growing baby. Additionally, breastfeeding women require more calories than pregnant women, and restricting their intake could negatively impact their milk supply.

Secondly, individuals with eating disorders or a history of disordered eating patterns should refrain from the keto diet. The restrictive nature of the diet may trigger unhealthy patterns and negatively impact overall health. Research suggests that non-diet approaches or less restrictive diets are more suitable for this group.

Thirdly, those with adrenal issues, hypothyroidism, or no gallbladder should also avoid the keto diet. The diet's high-fat content may be problematic for those without a gallbladder, as they may struggle to produce enough bile to break down fats adequately. For those with hypothyroidism, the keto diet's restriction of carbohydrates can interfere with the conversion of the inactive thyroid hormone T4 into the active hormone T3, potentially worsening symptoms.

Furthermore, the keto diet may not be advisable for people with digestive disorders, particularly those with irritable bowel syndrome (IBS) or chronic constipation. Low-carb diets tend to be low in fiber, which is crucial for maintaining regular bowel movements and supporting the health of the gut microbiome.

Lastly, children and teens should not follow the keto diet unless prescribed and closely monitored by a healthcare provider. They require a balanced diet to support their growth and development, and the keto diet may cause nutritional deficiencies. Adolescent females may experience changes in their menstrual cycle or delayed puberty due to the very low-carb nature of the diet.

It is always advisable to consult a licensed healthcare provider or dietitian before starting any restrictive diet like keto to ensure it is safe and suitable for your individual needs.
