Keto Weight Loss: Harder Long-Term Commitment

why weight loss is ahrder with long term keto

The keto diet is a popular weight-loss strategy, but its long-term effectiveness is questionable. While some people experience short-term weight loss, this is often due to water loss, and the restrictive nature of the diet can make it challenging to maintain. Additionally, the keto diet may lead to vitamin or mineral deficiencies, negatively impact athletic performance, and cause weight regain when relaxed. Furthermore, there are potential health risks associated with long-term adherence to the keto diet, including increased risk of heart disease and cancer. While the keto diet may be a good short-term solution for some, it is not a sustainable weight-loss strategy for everyone.

The keto diet is restrictive and hard to stick to long-term

The keto diet is also high in fat, with 70% to 80% of daily calories coming from fat sources. This can be difficult to sustain and may not be healthy in the long term. A diet high in saturated fat, for example, can increase levels of unhealthy cholesterol (LDL), which is a risk factor for heart disease. The keto diet may also be lacking in important nutrients, including fiber, which is important for gut health and can be found in whole grains, fruits, and vegetables.

The strict guidelines of the keto diet can be challenging to adhere to, and many people find it difficult to stick to long-term. It may also be difficult to get enough fiber on the keto diet, as whole grains, fruits, and some vegetables are restricted. This can have negative effects on digestive health and may increase the risk of heart disease, stroke, and type 2 diabetes.

The keto diet is also not suitable for everyone. For example, those with a history of digestive health issues, kidney disease, or eating disorders may be advised against following a restrictive diet like keto. Additionally, the keto diet may not be a good choice for athletes, as some research suggests that it could negatively impact performance in high-intensity activities.

Overall, the restrictive nature of the keto diet, both in terms of carbohydrate and fat intake, can make it difficult to stick to long-term. The potential health risks and challenges of adhering to the diet may outweigh the benefits for some people. It is important to consider individual needs and preferences when choosing a diet and to work with a healthcare professional to ensure a safe and effective approach to weight loss and maintenance.

It can be challenging to get the right nutrients

The keto diet is a low-carb, high-fat diet that can be challenging to follow in the long term. While it may lead to short-term weight loss, it can also be difficult to get the right nutrients, especially if you're not careful about the foods you choose.

The keto diet eliminates entire food groups, including starchy vegetables, grains, and most fruits. This can make it challenging to get enough vitamins and minerals, such as vitamin A, B vitamins, vitamin C, vitamin D, vitamin K, calcium, magnesium, and zinc.

In addition, the keto diet can be low in fiber, which is important for digestive health and can help reduce the risk of heart disease, stroke, and type 2 diabetes. Whole grains are one of the biggest sources of fiber, but they are limited on the keto diet.

To ensure you're getting enough nutrients on the keto diet, it's important to eat a variety of whole, nutrient-dense foods, such as:

  • Meat
  • Fatty fish
  • Eggs
  • Nuts and seeds
  • Healthy oils like olive oil and avocado oil
  • Low-carb vegetables like leafy greens, broccoli, and bell peppers

It's also important to monitor your nutrient intake and consider taking supplements to ensure you're getting enough of the right nutrients. Some useful supplements on the keto diet include:

  • MCT oil: Helps increase ketone levels and provides energy.
  • Minerals: Added salt and other minerals can be important, especially in the beginning, due to shifts in water and mineral balance.
  • Caffeine: Can provide benefits for energy, fat loss, and performance.
  • Exogenous ketones: Can help raise ketone levels and improve energy.
  • Creatine: Provides benefits for health and performance, especially if combining the keto diet with exercise.

By eating a variety of nutrient-dense foods and considering supplementation, you can help ensure you're getting the right nutrients while following the keto diet.

Weight regain is common after stopping keto

It is common to regain weight after stopping the keto diet, and this is often due to the restrictive nature of the diet. The keto diet is a very low-carb, high-fat diet that can lead to short-term weight loss for some people. However, restrictive diets like keto can be challenging to stick to in the long term, and many people regain weight once they come off it. This is because "crash" diets that lead to rapid initial weight loss can reduce your metabolic rate, making it harder to lose weight in the long term.

The key to defeating weight regain after dieting is to adopt a new lifestyle. It is normal to gain back some weight after stopping a particular diet—sometimes as much as 5-10 pounds immediately. However, this weight regain is not due to fat regain but is primarily due to water weight. When you reintroduce carbohydrates at more than 50 grams per day into your diet, you will start to restore glucose reservoirs in the form of glycogen in your muscles and liver. Every gram of glycogen carries with it 3 grams of water, which is where the immediate weight gain comes from.

To maintain your new weight, you need to match your total daily energy expenditure (TDEE). This can be calculated by first determining your basal metabolic rate (BMR), which is the number of calories your body burns at rest to keep vital functions going. Then, you add to that the extra energy you use throughout the day, which can be tracked using a fitness watch or step counter in conjunction with a calorie-counting app.

Tips for Transitioning Off Keto

  • Pay attention to how your body responds to the revised eating plan and make adjustments as needed.
  • Slowly scale back your fat intake while increasing your consumption of lean proteins, vegetables, and wholesome carbohydrates like fresh fruits, whole grains, and beans.
  • Add back carbs slowly and in small increments, such as 5-10 grams of carbohydrates per day.
  • Transition to a diet that more closely resembles the Mediterranean diet, which is ranked highly among dietitians.
  • Avoid previous bad habits and be selective about the types of carbohydrates you reintroduce, as they are usually the culprit behind weight gain.
  • Select fewer processed foods and lean meats like fish and skinless poultry instead of large amounts of processed meats.
  • Boost your physical activity levels by prioritizing exercise to help maintain your weight.

It may negatively impact athletic performance

How the Keto Diet May Negatively Impact Athletic Performance

The keto diet has become popular among endurance athletes as a performance enhancer. However, there is a concern that it may negatively impact athletic performance, especially for athletes involved in high-intensity, short-duration sports.

The Impact of Keto on Anaerobic Exercise Performance

A 2019 study published in the Journal of Sports Medicine and Physical Fitness found that people on the ketogenic diet performed worse at anaerobic exercise tasks than those eating more carbs. Their performance was 4 to 15 percent lower than the high-carbohydrate group. This included sprint-type activities like those in soccer and basketball, as well as short, intense activities like the 100-meter sprint and the triple jump.

The Body's State During Ketosis

The body is in a more acidic state when it's in ketosis, which may limit its ability to perform at peak levels. This increased acidity could be a factor in the decreased performance observed in the 2019 study.

The Impact of Keto on High-Intensity Aerobic Exercise

While keto may be beneficial for endurance athletes, there is evidence that it could compromise high-intensity aerobic exercise performance. This is supported by the 2019 study, which showed decreased performance in high-intensity cycling tasks after four days on a ketogenic diet.

The Adaptation Period for Keto and Athletic Performance

It's important to note that the body can take several months to adapt to using fats as its main energy source instead of carbohydrates. This "adaptation period" may influence the impact of the keto diet on athletic performance. Some athletes may need a longer period to become fully keto-adapted and see improvements in their performance.

The Importance of Carbohydrates for Athletes

Carbohydrates are essential for optimal athletic performance, especially for activities that require short bursts of energy. Carbohydrates provide a readily available source of energy for the body, which is crucial for high-intensity exercises.

The Potential for Weight Loss to Impact Performance

The keto diet may lead to weight loss, which could affect athletic performance. Substantial weight loss may negatively impact mental and hormonal health, as well as recovery time and general exercise performance. Additionally, weight loss can lead to a decrease in muscle mass, which can affect an athlete's power and strength.

In conclusion, while the keto diet has been touted as a performance enhancer for endurance athletes, there is evidence to suggest that it may negatively impact athletic performance, especially for high-intensity and short-duration sports. More research is needed to fully understand the impact of keto on athletic performance, and athletes should carefully consider the potential benefits and drawbacks before adopting this restrictive diet.

It can be hard to manage without a healthcare professional

The keto diet is a very low-carb, high-fat diet. It is different from other low-carb diets because it is high in fat, whereas other low-carb diets are high in protein. On the keto diet, 70%–80% of your calories come from fat, 10%–20% from protein, and 5%–10% from carbohydrates. This is a very different balance of food groups from a standard diet, which recommends 45%–65% of calories come from carbohydrates.

Because of the restrictive nature of the keto diet, it can be hard to manage without a healthcare professional. The keto diet is so strict that it can be difficult to adhere to for a long time, and many people regain any weight they have lost once they come off the diet. This is because restrictive diets can change your metabolism, making it harder to lose weight in the long term.

It is also possible to develop nutrient deficiencies on the keto diet, as it restricts some of the best sources of fibre, including starchy vegetables, legumes, fruits, and whole grains. Fibre is crucial for the health of your gut microbiome, and a lack of it can lead to digestive problems such as constipation or chronic diarrhoea.

The keto diet can also be difficult to manage without a healthcare professional because it can be hard to get enough calories. Most people feel more satisfied after eating ketogenic meals and snacks due to the filling effects of fat and protein. However, it is still possible to consume too few calories on the keto diet, which can slow your metabolism and make it harder to lose weight.

Finally, the keto diet may not be suitable for everyone. It may not be a good option for elite athletes or those wishing to build muscle mass, and vegetarians or vegans may struggle due to the diet's emphasis on meat, eggs, fish, and dairy.

For these reasons, it is important to consult a healthcare professional before starting the keto diet. They can help you determine whether it is a suitable option for you and provide guidance and support to ensure you are getting enough of the right nutrients.

Frequently asked questions

Weight loss is harder with long-term keto because restrictive diets like keto can be difficult to stick to. Many people regain weight once they come off the diet, and "crash" diets that lead to rapid initial weight loss can reduce your metabolic rate, making it harder to lose weight in the long term.

There are a lot of health experts who still don't know about the long-term effects of the keto diet on the body. However, some researchers warn that sticking to the diet long-term could be dangerous. For example, keto can lead to vitamin or mineral deficiencies, as it's hard to get enough fiber while cutting back on carbohydrates.

If you can't follow the keto diet but still like the idea of a low-carb diet, then carb cycling or a standard low-carb diet may be a better option.
