Keto And Muscle Retention: Friends Or Foes?

The ketogenic diet is a very low-carb, high-fat diet that has been linked to weight loss and other health benefits. It is a popular approach to dieting, but there are concerns about its impact on muscle retention.

The keto diet restricts carbohydrates, which promote the release of insulin, an anabolic hormone that helps create conditions for muscle growth. This has led to the assumption that keto may hinder muscle growth. However, studies show that it is possible to build and retain muscle on a keto diet.

Research suggests that keto may provide similar strength and performance gains as a conventional high-carb diet while aiding fat loss. A study comparing keto and traditional Western diets found that both were equally effective for muscle gain, strength, and performance.

However, there are conflicting findings regarding muscle retention on keto. Some studies indicate that keto can lead to muscle loss, especially in the legs, and this may be related to restricted protein intake and a lack of carbohydrates, which are essential for muscle building. On the other hand, other studies suggest that keto may have a protective effect on muscle mass, especially during aging or low-calorie diets.

Overall, while the keto diet can support muscle retention, more research is needed to fully understand its long-term effects on muscle health and performance.

The keto diet can lead to serious muscle loss, especially in the legs

The ketogenic diet is a high-fat, low-carb approach that has become a popular way to lose weight. However, it is extremely regimented and very difficult to stick to. The diet typically reduces carbohydrate intake to less than 50 grams per day and calls for moderately increased protein and fat intake.

There is ongoing research into the effects of the keto diet on muscle loss. Small studies suggest that people on the ketogenic diet lose muscle even when they continue resistance training. According to one small study, people who followed the keto diet for three months lost about the same amount of body fat and had about the same muscle mass changes as people following normal diets. However, the folks on keto did lose more leg muscle.

The loss of muscle mass as we age has serious consequences. Muscle is metabolically active and helps boost daily energy expenditure and mitigate age-related weight gain. Losing muscle mass can decrease functional strength and heighten the risk of falls.

The effects of the keto diet on muscle mass seem to differ depending on the type of muscle fiber. The activity of the enzymes involved in ketone utilization is different depending on muscle fiber types. The effects of the keto diet on skeletal and cardiac muscle are contradictory with respect to muscle weight, mitochondrial content, oxidative metabolism, antioxidant capacity, activity of various enzymes, as well as an impact on some pathological states.

While many studies demonstrate beneficial effects of the keto diet and fasting on skeletal or cardiac muscle, these diets should be used carefully because there is data suggesting that such nutritional manipulations can have negative, including long-term, consequences.

The keto diet may cause kidney stones and gout

The ketogenic diet is a popular strategy for rapid weight loss and can help with certain medical conditions like seizures and Type 2 diabetes. However, it can be a recipe for kidney stones and gout if not carefully managed. While the diet itself has not been linked to an increase in kidney stone diagnoses, doctors have observed more patients developing kidney stones while on the keto diet. This may be because keto dieters can quickly become dehydrated, and the diet can lead to increased levels of protein and uric acid in the body.

Dr. Koushik Shaw, a urologist, attributes the rise in kidney stones among his patients to high-protein, low-carb diets. He notes that eating more meat and fish can increase calcium and uric acid levels and acidify urine, contributing to kidney stones. Higher uric acid levels can also lead to gout, a painful type of arthritis.

To reduce the risk of kidney stones and gout while on the keto diet, it is important to stay hydrated and monitor meat intake. Dr. Thomas Chi, a urologist at the University of California, San Francisco, recommends moderation, especially when it comes to meat consumption. He also stresses the importance of hydration to flush out metabolic products. Adding lemon to water can help, as the citrate in lemons prevents calcium molecules from sticking together.

While there is no clear evidence that the keto diet directly causes kidney stones, it is advisable to check your risk factors before adopting this diet. Consulting a doctor and ensuring adequate hydration and a balanced diet can help mitigate the potential negative effects of the keto diet.

The keto diet may cause low blood sugar, which is dangerous for people with diabetes

The ketogenic diet, or keto diet, is a very low-carb, high-fat diet. It involves drastically lowering your carb intake and consuming fat instead. This helps your body transition into a metabolic state known as ketosis, where fat is converted into energy.

While the keto diet is often used for weight loss, it can also be used to aid people with epilepsy and control blood sugar levels. However, it is important to note that keto may not be suitable for everyone, especially those with diabetes.

The Keto Diet and Low Blood Sugar

The keto diet can lead to low blood sugar, or hypoglycemia, which is a potentially dangerous condition. Hypoglycemia occurs when blood glucose levels drop below the normal range of about 70 milligrams per deciliter. For people with diabetes, this can be especially risky, particularly if they are also taking certain medications or insulin. Therefore, it is crucial for individuals with diabetes to monitor their blood sugar levels regularly and consult their doctor to adjust medication dosages if needed.

Symptoms of hypoglycemia include:

• Weakness or shaking
• Moist skin or sweating
• Nightmares, bad dreams, or restless sleep
• Headaches and seizures

The Keto Diet and Diabetes

While keto can be effective for managing Type 2 diabetes by lowering blood sugar and promoting weight loss, it may not be suitable for everyone with this condition. The keto diet can be challenging to adhere to in the long term, and there is limited research on its long-term effectiveness and risks. Additionally, as a severely restrictive diet, keto may not distinguish between "good" and "bad" fats, which is important for individuals with diabetes who are already at an increased risk for high cholesterol and heart disease.

Furthermore, keto may not be a sustainable option for managing diabetes. Registered dietitian Melissa Matteo emphasizes that "restrictive meal plans like keto can be effective, but it's not always the right choice when it comes to sustainability." Instead, she suggests that individuals with diabetes should consider heart-healthy diets like the Mediterranean diet, which emphasizes fruits, vegetables, whole grains, beans, nuts, and moderate amounts of lean protein, poultry, fish, and dairy.

In conclusion, while the keto diet may offer benefits for individuals with diabetes, it is crucial to consult with a healthcare professional before starting this or any restrictive diet to ensure it aligns with your specific health needs and goals.

The keto diet is hard to follow and may lead to yo-yo dieting

The keto diet is extremely regimented and challenging to stick to. A single baked potato or slice of bread could constitute an entire day's worth of carbohydrates. While this is a deterrent for many, some people like the diet because of its strictness. However, adhering to the keto diet is not always easy, and a review found that only 45% of participants could follow the approach as prescribed.

The poor compliance was attributed to side effects, social isolation, and cravings. Some people in the study "reported the diet simply wasn’t helping them lose weight".

The keto diet can also lead to yo-yo dieting because people have difficulty staying on the restrictive diet permanently. This can have other negative effects on the body. There is a lack of long-term studies on the keto diet, which may be because it's difficult to follow, so people aren't staying on it for long.

"If trying to go keto causes you to yo-yo and go off and on diets, that has impacts related to weight fluctuations and increased mortality risk," said Sharon Palmer, a dietitian from California.

The highly restrictive nature of the keto diet makes it hard to follow and may lead to yo-yo dieting, which can have negative health consequences.

The keto diet can lead to dehydration and a loss of electrolytes

The keto diet is a very low-carb, high-fat diet that is often used for weight loss. It involves drastically lowering your carb intake and putting your body into a metabolic state known as ketosis, where it burns fat for energy instead of glucose. While this diet is generally safe and can be part of a healthy lifestyle, it can lead to dehydration and a loss of electrolytes, especially when first starting out.

Here's why: when you're on the keto diet, your body produces ketones to burn fat for energy instead of glucose. This process leads to the loss of water and electrolytes, which can result in dehydration. Carbohydrates are what help your body retain water and sodium, so when you cut them out, it's easier to lose necessary electrolytes like sodium, magnesium, potassium, and calcium through sweating. This can lead to an imbalance in electrolytes, which is crucial to maintaining proper hydration.

Dehydration and electrolyte imbalances can cause a range of unpleasant symptoms, including muscle cramps, headaches, keto flu, fatigue, constipation, increased thirst, and hunger. To avoid these issues, it's important to focus on proper hydration and electrolyte intake while on the keto diet. Here are some tips to help you stay hydrated and maintain electrolyte balance:

• Start your day with a glass of water and aim to drink around eight glasses throughout the day.
• Keep a full glass of water nearby to remind yourself to drink regularly.
• Use a tracking cup or download an app to monitor your daily water intake.
• Stay hydrated with low-sugar broths, juices, sports drinks, and popsicles, in addition to water.
• Eat whole foods like leafy vegetables, nuts, seeds, avocados, cucumbers, and berries, which are high in water content and electrolytes.
• Increase your salt intake by salting your food or drinking bouillon, as keto dieters tend to excrete more salt.
• Consider taking electrolyte supplements or drinking electrolyte-infused water to ensure adequate intake.
• Be mindful of your caffeine and alcohol intake, as these can contribute to dehydration.
