Restarting the keto diet can be a great way to lose weight, but how long it takes to lose 20 pounds will depend on several factors. The keto diet is a high-fat, low-carb diet that can lead to weight loss by switching the body to a state of ketosis, where it burns fat for fuel instead of glucose. The time it takes to enter ketosis varies, but it usually takes anywhere from 2 to 7 days. During the first week of the keto diet, people often experience rapid weight loss due to the loss of water weight, which can range from 2 to 10 pounds. After the initial week, weight loss typically occurs at a steadier pace of about 1 to 2 pounds per week. According to a keto diet expert, if individuals stay at a calorie deficit and consistently follow the diet, they can expect to lose 10 pounds or more in the first month. However, it's important to note that weight loss varies depending on factors such as starting weight, age, body fat percentage, and activity level. To maximize weight loss on the keto diet, it's crucial to plan meals, manage electrolytes, and ensure a consistent calorie deficit.
| Characteristics | Values |
|---|---|
| Weight loss in the first week | 2-10 pounds |
| Weight loss after a month | 10 pounds or more |
| Weight loss after 90 days | 20-25 pounds |
| Weight loss rate | 1-3 pounds per week |
What You'll Learn
The importance of planning meals
Planning meals is an essential part of the keto diet. The keto diet is a high-fat, low-carb, and moderate-protein diet. It is important to plan meals to ensure that you are eating the right balance of foods and staying within the strict dietary requirements.
Planning meals can help you to stay organised and ensure that you are getting all the nutrients you need. It can also help you to save time and money by cooking in bulk and reducing food waste. Planning meals in advance can also help you to stick to the keto diet and avoid making less healthy choices.
When planning keto meals, it is important to focus on high-fat, low-carb foods. This includes foods such as eggs, meats, dairy, and low-carb vegetables. It is also important to avoid high-carb foods such as bread, pasta, rice, potatoes, and sugar.
There are many resources available to help with keto meal planning, including online tools, calculators, and recipes. It is also a good idea to consult with a healthcare professional or registered dietitian to ensure that you are getting all the nutrients you need and that the keto diet is safe for you.
Sticking to a keto meal plan can help to simplify your keto journey and set you up for success. It can also help you to lose weight and improve your health.

The keto diet's impact on energy levels
The keto diet can have a notable impact on energy levels, with many people reporting increased energy and focus. However, in the initial stages of the diet, it is common to experience a decrease in energy and performance, often referred to as the "keto flu".
Short-Term Fatigue and Decreased Performance
The transition to a keto diet can be challenging for new dieters, as the body adapts to burning fat for fuel instead of carbohydrates. This can lead to feelings of weakness and fatigue, as well as a decrease in exercise performance. This is caused by the reduction in glycogen stores in the muscles, which provide the most efficient fuel source for high-intensity exercise.
Increased Energy and Focus
Once the body enters ketosis and adapts to burning fat and ketones as fuel, many people experience increased energy levels and improved focus. This is because ketones are an extremely potent fuel source for the brain. Eliminating carbohydrates can also help stabilize blood sugar levels, further enhancing focus and brain function.
Individual Variations
It is important to note that the impact of the keto diet on energy levels can vary from person to person. Factors such as starting weight, age, height, body fat percentage, activity level, and pre-existing health conditions can influence the rate of weight loss and energy level changes. Additionally, the quality of food consumed on the keto diet matters; focusing on healthy, nutrient-dense foods can contribute to increased energy levels.
Managing Energy Levels on the Keto Diet
To minimize fatigue during the transition to the keto diet, electrolyte supplements can be beneficial. Ensuring adequate intake of sodium, potassium, and magnesium can help combat symptoms of "keto flu", which is often characterized by electrolyte depletion.
In summary, while the keto diet may cause short-term decreases in energy and performance, many people experience increased energy and focus once their bodies adapt to burning fat and ketones as fuel. The impact on energy levels can vary depending on individual factors, and proper nutrition and supplementation can help manage energy levels during the transition.

How to calculate your keto macros
The key to success on a ketogenic diet is eating the right amount of daily calories in the right proportions of fat, protein, and carbohydrates (or macronutrients). To calculate your keto macros, you can use a keto macro calculator, which will take into account your unique age, body measurements, weight loss goals, and physical activity. Here is a step-by-step guide on how to calculate your keto macros:
Step 1: Determine Your Body Fat Percentage
To calculate your keto macros, you first need to know your body fat percentage. You can estimate your body fat percentage by using a body fat scale or by taking measurements and using an online body fat percentage calculator.
Step 2: Calculate Your Lean Body Mass
Your lean body mass is your total body weight minus your body fat percentage. To calculate this, multiply your total body weight in pounds by your body fat percentage as a decimal. Then, subtract this number from your total body weight.
Step 3: Determine Your Protein Intake
On a ketogenic diet, it is recommended to consume around 1 gram of protein per pound of lean body mass. This will help you maintain muscle mass while losing weight. Multiply your lean body mass by 1 gram to determine your daily protein intake in grams.
Step 4: Calculate Your Carbohydrate Intake
The ketogenic diet is a low-carb diet, and it is recommended to limit your carbohydrate intake to 20-25 grams of net carbs per day. Net carbs are calculated by subtracting fiber from total carbs, as fiber is not digestible and does not impact blood sugar or ketosis.
Step 5: Calculate Your Fat Intake
Fat is your primary fuel source on a ketogenic diet, so it is important to ensure adequate fat intake. Your fat intake will make up the remainder of your daily calorie intake after accounting for protein and carbohydrate intake. Multiply your total calorie intake by 0.4 to determine the number of calories from fat, then divide by 9 to get the number of grams of fat, as there are 9 calories per gram of fat.
Step 6: Adjust and Monitor
It is important to remember that everyone's body is different, and you may need to adjust your keto macros based on your individual results. Monitor your weight loss progress, energy levels, and how you feel overall. You can also consider tracking your ketone levels to ensure you are in ketosis.

The role of exercise in weight loss
Exercise is an integral part of any weight loss program. While it is possible to lose weight through dietary restriction alone, exercise has multiple health benefits and can help contribute to weight loss and weight maintenance.
Benefits of Exercise
Combining exercise with a healthy diet is a more effective way to lose weight than depending on calorie restriction alone. Exercise can help prevent or even reverse the effects of certain diseases. It lowers blood pressure and cholesterol, which may prevent a heart attack. It also lowers the risk of developing certain types of cancers such as colon and breast cancer.
Amount of Exercise Needed for Weight Loss
To reap the health benefits of exercise, it is recommended to perform some form of aerobic exercise at least three times a week for a minimum of 20 minutes per session. However, more than 20 minutes is better if weight loss is the goal. Incorporating just 15 minutes of moderate exercise — such as walking one mile — on a daily basis will burn up to 100 extra calories (provided there is no increase in calorie consumption afterwards). Burning 700 calories a week equals 10 lbs. of weight loss over the course of a year.
Types of Exercise
The type of exercise chosen for weight loss is less important than doing it consistently. That's why experts recommend picking exercises that are enjoyable, so they are easier to stick to.
Any exercise program should include some form of aerobic or cardiovascular exercise, such as walking, jogging, cycling, swimming, and dancing. Working out with weights is also beneficial, as it helps build muscle, which in turn burns more calories.
Incorporating Exercise into Your Lifestyle
Small changes in daily routines can make a big difference in weight loss. Some examples of healthy lifestyle habits include:
- Walking or riding a bike to work or while running errands
- Taking the stairs instead of the elevator
- Parking farther away from destinations and walking the remaining distance

How to maintain ketosis
To maintain ketosis, you must consistently eat a low-carb, high-fat diet. This means limiting your carb consumption to between 20-50 grams per day. The total amount depends on your gender, weight, and age. Avoid high-carb vegetables like peas and squash, starchy foods like corn and potatoes, and grains like wheat, rice, and oats.
Instead, focus on eating healthy fats, such as meat (including beef, chicken, and even bacon), high-fat vegetables like avocados, and full-fat dairy products like cheese, butter, and heavy cream. Other good sources of fat include coconut oil and olive oil.
In addition to diet, exercise is key to maintaining ketosis. Aim to exercise at least three times a week for half an hour or more. Running or power walking for half an hour a day will help you stay in ketosis. Exercise is important because it will help you burn off any carbs you consume, thus helping your body stay in ketosis. If you consume extra carbs on a given day, you'll need to exercise more to burn them off.
Intermittent fasting can also help maintain ketosis by giving your body a chance to process any carbs you consume and to begin to break down stored fat. Try to fit all your eating into an 8-hour window during the day.
To ensure you're maintaining ketosis, you can test your blood ketone levels using a blood ketone meter. Your optimal ketosis level should be between 0.5-3.0 mmol/L.
