The ketogenic diet, commonly known as the keto diet, is a low-carbohydrate, high-fat diet that has gained popularity for its weight-loss benefits. While the keto diet has been associated with improved muscle function and strength in older individuals, its impact on muscle mass is more complex. Some studies suggest that the keto diet can lead to muscle shrinkage and bone loss, while others indicate that it can help maintain muscle mass and prevent deterioration. The keto diet's influence on muscle mass may depend on various factors, including total energy and protein intake, and it is essential to consider individual variations and specific circumstances when evaluating its potential benefits or drawbacks.

Keto diets can prevent muscle deterioration and restore muscle function
The ketogenic (keto) diet is well known as a weight-loss strategy, but it can also have a significant impact on muscle health and brain function. A keto diet involves eating high-fat, low-carbohydrate foods to reach a state of ketosis, where the body burns fat for fuel instead of sugar. While this dietary approach can be effective for weight loss, it has sparked debates about its effects on muscle mass and performance.
Research suggests that the keto diet can prevent muscle deterioration and restore muscle function, particularly in aging individuals. A study conducted by UC Davis Health, led by molecular exercise physiologist Keith Baar, found that a keto diet improved muscle function in older animals by preventing muscle mass loss due to age (sarcopenia). The study also revealed positive effects on brain health, including the potential to treat neurocognitive diseases and age-related neurological decline.
The keto diet's ability to prevent muscle deterioration may be attributed to its impact on muscle energetics and metabolism. Muscles are high-energy-demanding tissues, and changes in their energy metabolism can influence their function. The keto diet increases fat oxidation and reduces carbohydrate dependence, which can affect muscle tissue through ATP supply and the production of metabolic intermediates. Additionally, the keto diet has been found to increase the number of mitochondria in muscles, enhancing the muscle's ability to produce energy from fat and break down neurotoxins, thereby protecting the brain from cell loss and improving brain function.
While the keto diet has shown promising results in preventing muscle deterioration and improving brain health, it may not provide substantial benefits for athletes. The keto diet slows the maximal rate of energy production, which can be detrimental for athletes who require quick energy production during sprinting or endurance sports. Furthermore, excessive protein intake on a keto diet can disrupt the state of ketosis, so protein consumption should be optimized to maintain the desired metabolic state.
In conclusion, the keto diet has been found to prevent muscle deterioration and restore muscle function, particularly in aging individuals. It achieves this by improving muscle energetics, increasing mitochondria count, and enhancing the breakdown of neurotoxins. However, the keto diet's impact on muscle mass and performance is still a subject of ongoing debate, and it may not be the best dietary strategy for athletes due to its effect on energy production rates.

Keto diets can cause muscle shrinkage and bone loss
The ketogenic diet is a low-carbohydrate, high-fat diet that has become popular for weight loss. However, there are some side effects to be aware of before starting this diet, including muscle shrinkage and bone loss.
Several studies have found that the keto diet can lead to muscle shrinkage and a decrease in muscle mass. One study found that individuals who performed upper and lower body training protocols for two months saw a decrease in muscle mass while on a keto diet, compared to those on a non-ketogenic diet who added muscle mass. Another study found that people who followed the keto diet for three months lost about the same amount of body fat but also lost more leg muscle compared to those on normal diets.
The keto diet has also been found to undermine exercise efforts, which may contribute to muscle shrinkage. An official position paper from the International Society of Sports Nutrition noted the negative impact of ketogenic diets on athletic performance, with keto diets associated with increased feelings of fatigue and mood disturbances during physical activity.
In addition to muscle shrinkage, keto diets can also lead to bone loss. Markers for bone breakdown are higher, while markers for bone building are lower on low-carbohydrate ketogenic diets. This can lead to lower bone mass and osteopenia (weak bones), especially in children who are fed a ketogenic diet to treat epilepsy.
While the keto diet may lead to muscle shrinkage and bone loss in some individuals, there are also studies suggesting that it can improve muscle function and prevent muscle mass loss due to age. One study found that animals on a ketogenic diet maintained their muscle strength, endurance, and muscle mass into old age. Another study comparing the keto diet to a hypocaloric diet in children and adolescents with obesity found that the keto diet was more effective in terms of weight loss and metabolic parameters.

Keto diets can impair athletic performance
The ketogenic diet is a low-carbohydrate, high-fat diet that has become popular for weight loss. While it has been shown to have positive effects on muscle mass and strength in older people, the effects on athletic performance are less clear.
Several studies have found that the keto diet can impair athletic performance. An official position paper from the International Society of Sports Nutrition noted that ketogenic diets can undermine exercise efforts in both high- and low-intensity workouts. This may be due to the increased feelings of fatigue and mood disturbances associated with ketosis, as well as the potential for muscle shrinkage and bone loss. Indeed, one study found that individuals on a keto diet lost muscle mass, particularly in the legs, while another study of soccer players found contradictory results on sport performance.
The keto diet may also affect athletic performance by impacting energy metabolism. Muscles are one of the major sites of glucose and energy uptake, and the keto diet decreases carbohydrate oxidation while increasing fat oxidation. This change in energy metabolism could potentially impair athletic performance, particularly in high-intensity workouts that rely on carbohydrates for fuel.
However, there is some evidence that the keto diet may improve athletic performance in certain contexts. For example, the keto diet has been found to increase the number of mitochondria in muscles, which could enhance endurance. Additionally, the keto diet has been shown to be effective for weight loss, which could potentially improve athletic performance in sports where a lower body weight is advantageous.
Overall, while there is some conflicting evidence, the keto diet may impair athletic performance due to its effects on muscle mass, bone health, energy metabolism, and fatigue. More research is needed to fully understand the impact of the keto diet on athletic performance, particularly in team sports and high-intensity workouts.

Keto diets can cause bone fractures and kidney stones in children
The ketogenic diet (KD) is a medically supervised, high-fat, low-carbohydrate, and restricted protein diet. It has been used to treat patients with epilepsy, especially children. While the keto diet has been shown to improve muscle function in older people, it may have adverse effects on bone health and kidney health in children.
Children on the KD have shown differences in skeletal development, with lower bone mass and density. A study found that patients treated with the ketogenic diet demonstrated an average decrease in bone mineral density (BMD) of 0.16 SD (relative to age-matched referent children) for every year they remained on the diet. Another study showed that children on the KD exhibited differences in skeletal development that may be related to the diet. These changes were independent of height but appeared more pronounced in ambulant patients. The exact mechanism of how KD affects bone health is not yet fully understood, and longer-term follow-up is required to determine the fracture risk throughout life.
In addition to bone health issues, there is also an increased risk of kidney stones in children on the KD. A cohort study of 195 children on the ketogenic diet for epilepsy found that 13 children (6.7%) developed kidney stones. The estimated pooled incidence of kidney stones in children on the ketogenic diet ranges from 5.6% to 5.9%. Subgroup analyses showed that 48.7% of kidney stones were uric stones, 36.5% were calcium-based stones, and 27.8% were mixed uric acid and calcium-based stones. The use of oral potassium citrate has been found to reduce the incidence of kidney stones in children on the ketogenic diet.
In conclusion, while the keto diet has been shown to have benefits for muscle function and brain health in older individuals, it may have negative consequences for bone and kidney health in children. More studies are needed to fully understand the long-term effects of the keto diet on bone development and kidney health in this vulnerable population. Clinicians should carefully monitor bone health and kidney function in children on the ketogenic diet and take preventive measures to mitigate potential risks.

Keto diets can improve muscle function in older people
A ketogenic or keto diet is a low-carbohydrate, high-fat diet. In ketosis, the body burns more fat for fuel, instead of sugar, and produces acids known as ketones. The keto diet is widely known as a weight-loss diet, but it also has a far-reaching effect on the muscles and the brain.
A UC Davis Health study found that a keto diet improves muscle function in older animals by preventing muscle mass loss due to age (sarcopenia). The study's lead author, molecular exercise physiologist Keith Baar, noted that a keto diet "prevents muscle deterioration and even restores muscle function." The study also found that a keto diet can increase the number of mitochondria in muscles, which produce energy and help the body break down harmful metabolites known as kynurenines.
The keto diet has also been shown to have positive effects on brain health. The enzymes produced by the muscles during a keto diet break down neurotoxins and prevent them from getting into the brain, protecting the brain from cell loss and improving brain function. Additionally, a keto diet has been used for many years to treat epilepsy and other neurocognitive diseases, and it may also have potential in treating age-related neurological decline and Alzheimer's disease.
While a keto diet can have benefits for muscle and brain health, it is important to note that it may not be suitable for everyone. Some people may experience negative side effects, such as the "keto flu," which includes symptoms like headaches, fatigue, and difficulty sleeping. Additionally, there can be issues with bone health when people switch to low-carbohydrate ketogenic diets, as markers for bone breakdown are higher and markers for bone building are lower.
Overall, a keto diet may be a viable option for older adults looking to improve muscle function, prevent muscle loss, and enhance brain health. However, it is always recommended to consult with a healthcare professional before starting any new diet, especially for those with unique needs and health goals, such as older adults.
