Understanding Keto Weight: Water Vs Fat

The keto diet is a popular choice for people looking to lose weight, but how do you know if the pounds you're shedding are water weight or fat? While both look the same on the scale, water weight and body fat are very different. Water weight tends to come and go quickly, while body fat builds up gradually over time. If you've experienced sudden weight fluctuations, you're most likely dealing with water weight, which can be caused by diet, hormones, or hydration levels. On the other hand, if your weight has been gradually increasing alongside changes in your diet and exercise habits, you may have gained body fat. This paragraph introduces the topic of distinguishing water weight from fat loss when following a keto diet and provides a brief overview of the key differences between the two.

Weight loss in the first week of keto is mostly water weight

The keto diet is a popular choice for people looking to lose weight. And it's true that many people notice dramatic weight loss in the first week of starting the diet. However, it's important to understand that this initial weight loss is mostly due to a loss of water weight, rather than fat loss.

When you restrict carbohydrates on the keto diet, your body rapidly burns through glycogen, which is the stored form of carbohydrates in your liver and muscles. Glycogen is bound to water, typically at a ratio of 3 grams of water for each gram of glycogen. So when you burn through these stored carbohydrates, the water is excreted in your urine or sweat, resulting in a rapid loss of water weight.

This water weight loss can vary depending on your size and how much water weight you're carrying. People with a higher overall weight initially tend to lose the most water weight in the first week, with some reports of up to 10 pounds or more. On the other hand, those with a lower initial body weight may only lose a single pound or two in their first week.

While some fat loss may occur during this initial period, it's unlikely that this is the main cause of the dramatic weight loss seen in the first week of keto. The larger you are, the more water weight you're likely to lose, and it's uncommon for much of this initial weight loss to be from fat.

However, once you enter ketosis, which usually happens within a week of starting the keto diet, it becomes much easier to utilise your own stored fat for energy, which is why the keto diet can be effective for weight loss. At this stage, your weight loss will probably slow down, but it's likely to be more fat than water that you're losing.

So if you're considering the keto diet for weight loss, it's important to understand that the initial rapid weight loss is mostly water weight. The true benefits of keto for weight loss will be seen in the subsequent weeks and months as your body adjusts to burning fat for energy.

Water weight tends to come on quickly

Water weight gain can also be the result of certain medications, or more serious health conditions such as heart failure, kidney disease, or deep vein thrombosis. If you suspect that your water retention is linked to an underlying health condition, it's important to consult a doctor.

If you've gained weight quickly, it's also possible that you've gained muscle mass, particularly if you're exercising regularly and performing resistance training.

There are a few ways to determine whether your weight gain is due to water weight or fat. One simple test is to press your index finger into the fat on the back of your hand. If it leaves an impression, it's likely that you're carrying water weight. Additionally, water weight often comes with puffiness and bloating, particularly in the abdomen, hands, and feet.

Body fat is stored throughout the body and doesn't fluctuate easily

Body fat is distributed across the body and is not easily affected by fluctuations. While weight loss can occur on the keto diet, it is important to understand that the number on the scale does not always accurately reflect changes in body fat. Weight can vary significantly due to factors such as food and water intake, muscle gain, and hormonal changes.

The keto diet is associated with rapid initial weight loss, which is primarily attributed to the depletion of glycogen stores and the subsequent loss of water weight. Each gram of glycogen is bound to approximately 3 grams of water, and the average human stores around 100 grams of glycogen in the liver and 350-700 grams in muscle tissues. As the body switches to burning fat for energy, it releases the water bound to glycogen, resulting in noticeable weight loss. However, this initial weight loss is mostly water-weight loss rather than fat loss.

The keto diet's restriction of carbohydrates leads to a decrease in glycogen stores, which can result in a loss of water through increased urination. This loss of water weight can be significant, ranging from 1 to 10 or more pounds during the first week of keto. The larger an individual is, the more water weight they are likely to lose at the beginning of the keto diet.

While the keto diet can lead to a reduction in body fat, it is not typically the primary cause of rapid initial weight loss. The scale, therefore, may not provide an accurate representation of how the body is responding to a change in nutrition, especially in the case of a low-carb diet like keto. Other factors, such as muscle gain and water weight fluctuations, can impact the number on the scale without reflecting changes in body fat.

Weight fluctuations throughout the day are normal

The food and drink you consume have weight, and this can cause your weight to increase slightly while your body processes and expels them. For example, consuming two cups of water or other beverages will increase your weight by about one pound. The calories in food are used to fuel your body's natural processes, and any waste products are processed and excreted in the form of urine and stool.

Exercise can also cause weight fluctuations. Intense cardiovascular activity can lead to fluid loss through sweating, resulting in temporary weight loss. Strength training, on the other hand, can cause muscle damage, swelling, and increased glycogen storage, which may lead to apparent weight gain after a workout.

Hormonal changes, particularly during a woman's menstrual cycle, can also impact weight. Many women experience weight gain and water retention during their period, with fluid retention typically peaking on the first day of menstrual flow.

Additionally, stress can affect weight by disrupting satiety signals and leading to cravings for processed and high-sodium foods.

To accurately track weight changes, it is recommended to weigh yourself at the same time each day, preferably first thing in the morning after a glass of water, as this helps to control variables such as food and fluid intake.

Weight loss slows down after the initial days and weeks of keto

After the initial rapid weight loss in the first week of the keto diet, weight loss will slow down. This is normal and to be expected. In the first week, people often lose a dramatic amount of weight, anywhere from 2-10 pounds, but this is mostly water weight.

After the first week, you can expect to lose a steady amount of 1-2 pounds per week on average. This is when your body moves into ketosis and starts to burn fat. You will also start to feel the benefits of keto, with fewer cravings and more energy.

After three months of following the keto diet, most people find that weight loss slows down even further, perhaps to 1-2 pounds lost every couple of weeks. This is because, by this stage, most of the weight loss will have already happened, and you may have reached your target weight. If you haven't, don't be discouraged; there are ways to improve your weight loss results.

Tips to Improve Weight Loss Results

• Recalculate your macronutrient intake: As your body weight and activity levels change, you will need to adjust your macronutrient targets accordingly.
• Increase your activity level: After three months, you may find that your physical activities are no longer challenging enough. Be sure to increase the intensity and difficulty of your workouts to continue challenging your body.
• Take body measurements: Remember that building muscle can change your body composition, and muscle weighs more than fat. Taking body measurements and calculating your body fat percentage will give you a more accurate picture of your progress than just weighing yourself.
• Be patient and consistent: Weight loss is not always linear, and there will be natural fluctuations. The key is to be consistent with your diet and exercise habits and give your body time to respond to the changes.

Other Benefits of Keto

Even if the number on the scale isn't changing as quickly as you'd like, remember that the keto diet has numerous other health benefits. These include increased energy, healthier hair, skin, and nails, and a reduced risk of chronic diseases. So, focus on these overall health improvements rather than just the number on the scale.
