Keto For Skinny People: Effective For Weight Loss?

The keto diet is a popular choice for people looking to lose weight. However, some people who are already skinny may be interested in trying the keto diet for its other potential benefits. While it is true that the keto diet can lead to weight loss, there are ways to maintain weight while still enjoying the benefits of keto. For example, skinny people interested in keto can ensure they are getting enough calories by eating at maintenance or above. Additionally, they can incorporate strength training or high-intensity interval training to build muscle and prevent muscle loss.

Keto can help reduce acne

The ketogenic diet, or keto, is a low-carb, high-fat, and high-protein diet. It is often adopted by people looking to lose weight and improve their health. While there is no conclusive scientific evidence, keto is believed to help clear acne due to its impact on blood sugar, insulin, and inflammation.

Acne is an inflammatory skin disorder where hair follicles become clogged with sebum (oil) and dead skin cells. A keto diet can help prevent acne by dramatically reducing blood sugar, insulin, and inflammation, which are triggers for acne.

The keto diet restricts carbohydrates to up to 50 grams per day, which leads to lower blood sugar and insulin levels. This, in turn, helps regulate androgen levels and decreases insulin-like growth factor (IGF-1), reducing sebum production.

Additionally, keto encourages the consumption of healthy fats, particularly omega-3 fatty acids, which have anti-inflammatory properties. This combination of reduced carbs and increased healthy fats improves skin health and helps prevent acne.

Tips for Maximizing Keto's Benefits for Acne

• Avoid highly processed foods, even those marketed as keto-friendly, as they may contain hidden sugars and carbs that can spike insulin and cause skin problems.
• Get quality sleep. Research shows that poor sleep quality can worsen acne. Aim for at least 7 hours of sleep per night.
• Incorporate physical activity into your keto lifestyle. Exercise helps regulate blood sugar, reduce insulin resistance, and flush toxins out of your system, all of which can improve skin health.
• Consider cutting out dairy. Dairy contains growth hormones and extra carbs that may trigger acne. Try almond milk or other keto-friendly vegan alternatives.
• Try intermittent fasting. It helps boost weight loss and reduce facial breakouts by mitigating inflammatory pathways and inhibiting mTOR activation, which increases androgen hormones.
• Consume omega-3 fatty acids. Omega-3s help balance out omega-6 fatty acids, which are associated with inflammation. Fatty fish like salmon, tuna, mackerel, and sardines are good sources of omega-3s.

It may improve brain functioning

The ketogenic diet has been shown to improve brain functioning in several ways. Firstly, it can increase the number of mitochondria, the "energy factories" in brain cells, leading to enhanced energy production and improved cognitive function. This is especially beneficial for conditions like Alzheimer's disease, where brain cells often degenerate, resulting in cognitive dysfunction and memory loss.

Secondly, the ketogenic diet acts as a potent anti-inflammatory agent by reducing the production of reactive oxygen species and enhancing the activity of glutathione peroxidase, a natural antioxidant. This anti-inflammatory effect may be particularly advantageous for individuals with neurodegenerative diseases, stroke, or ageing-related cognitive decline, as inflammation is a common feature of these conditions.

Additionally, the ketogenic diet can modulate neuronal excitability by inhibiting the release of the excitatory neurotransmitter glutamate and increasing the levels of the inhibitory neurotransmitter GABA. This restoration of the balance between excitation and inhibition in the brain may contribute to the diet's anti-seizure and neuroprotective effects.

Furthermore, the ketogenic diet increases the levels of polyunsaturated fatty acids (PUFAs), such as DHA and EPA, which are known for their brain-health benefits. These PUFAs help to reduce inflammation and inhibit the expression of pro-inflammatory factors, thereby providing additional neuroprotection.

Finally, the ketogenic diet may improve memory and cognitive function, as evidenced by studies in elderly individuals with mild cognitive impairment and Alzheimer's disease. These individuals experienced enhanced verbal memory performance and overall cognitive improvement when following a ketogenic diet.

While the ketogenic diet shows promise in improving brain functioning, more large-scale clinical trials are needed to confirm these benefits and determine the optimal conditions for its safe and effective use.

Keto can offer heightened levels of focus and mental clarity

The ketogenic diet is well-known for being a low-carb, high-fat diet for short-term weight loss. However, it has another less-talked-about benefit: ketosis for mental clarity and heightened levels of focus.

Ketosis is a state the body enters when deprived of carbohydrates (glucose), where your body uses ketones, a natural chemical made in the liver to burn fat as its primary fuel source. Fat via ketones is the brain’s preferred fuel source. By following a low-carb, high-fat diet, we achieve ketosis.

The basis of the keto diet is that it uses a macronutrient balance to get a certain response from the body. People who follow a ketogenic diet eat normal amounts of protein, higher amounts of fat, and lower amounts of carbohydrates than the average person.

The increased fat intake from a keto diet can offer benefits for brain function since our brains need mostly fatty acids omega-3 and omega-6 to be healthy and function properly. Most of our brain tissue is made up of fatty acids, so it makes sense that they would be vital for the health of our brain and also for functions such as learning and sensory execution.

• Ketosis improves brain function: Ketones can benefit those with neurodegeneration issues like epilepsy, Alzheimer’s disease, Parkinson’s disease, and aging-related cognitive diseases. The production of ketone bodies can help in these cases because the brains of people with these problems can’t use enough of the available glucose to handle cognition and perception. A ketogenic diet can then assist by providing a backup source of energy.
• Ketosis helps you focus: An unbalanced diet can lead to a lack of mental clarity, a foggy brain, and difficulty remembering important facts or focusing on tasks. These symptoms normally involve two factors: Glutamate, a neurotransmitter that promotes stimulation in the body and is vital for brain function and learning; and GABA (gamma-aminobutyric acid), the main neurotransmitter in the body that reduces stimulation. When your body has too much glutamate and not enough GABA available, you’ll likely experience brain fog and have trouble concentrating, as well as decreased social behaviour and increased anxiety. Ketones provide the brain with another source of energy and allow it to more efficiently process the extra glutamate into GABA. By helping increase the production of GABA, ketones can then help decrease the amount of extra neurons that are firing in the brain and improve mental focus.
• Ketosis improves your memory: Ketone bodies may reduce free radicals in the brain by improving the efficiency and energy levels of the mitochondria, which produce energy for the body’s cells. Ketosis can also help make new mitochondria and increase ATP in your brain’s memory cells. An example of this was shown during a rat study in which those subjects given a diet of mostly ketones performed better in physical and cognitive tests than those fed a high-carbohydrate diet or typical Western diet.

It's important to note that within the first few weeks of starting a ketogenic diet, as your carb consumption is greatly reduced and your body uses up the glucose that’s left over, you might experience some initial mental fog or headaches. This is temporary and usually due to your body flushing out electrolytes from the diuretic effect of ketosis.

It has been linked to improved health in women with PCOS

Polycystic ovary syndrome (PCOS) is a common endocrine disorder affecting women of reproductive age. It is associated with obesity, hyperinsulinemia, and insulin resistance. A ketogenic diet has been linked to improved health in women with PCOS.

A pilot study by Mavropoulos et al. investigated the effects of a low-carbohydrate, ketogenic diet (LCKD) on overweight and obese women with PCOS. The study found significant reductions in body weight, percent free testosterone, LH/FSH ratio, and fasting serum insulin in women with obesity and PCOS over a 24-week period. Two women in the study became pregnant despite previous infertility problems.

Another study by Paoli et al. examined the effects of a ketogenic diet in overweight women with PCOS. The study found a significant decrease in blood glucose and insulin levels, as well as an improvement in HOMA-IR. Additionally, the LH/FSH ratio, total and free testosterone, and blood levels of dehydroepiandrosterone sulfate (DHEAS) were significantly reduced. Estradiol, progesterone, and sex hormone-binding globulin (SHBG) levels increased.

A systematic review and meta-analysis by Barrea et al. assessed the effects of a very low-calorie ketogenic diet (VLCKD) on PCOS. The review found that VLCKD was associated with significant body weight reduction, improvements in body composition, and metabolic parameters. It was also found to be effective in improving insulin sensitivity and reducing waist circumference and fat mass.

These studies suggest that a ketogenic diet may be beneficial for women with PCOS by improving metabolic and reproductive health, reducing weight, and increasing the chances of pregnancy. However, more research is needed to fully understand the long-term effects of a ketogenic diet on PCOS.

It may reduce seizures

The ketogenic diet has been used to treat epileptic seizures, especially in children with refractory epilepsy, which does not respond to medical treatment. The diet is thought to reduce seizure frequency and severity. It is a high-fat, low-carbohydrate diet that induces a metabolic state called ketosis. While the exact mechanism is not known, there are several theories as to how it works.

One theory suggests that the ketones produced when the body uses fat as fuel instead of carbohydrates can prevent seizures. Ketones can reduce the number of chemicals in the brain that cause neurons to fire. Neurons are the messengers that send information throughout the brain and central nervous system. By reducing neuron activity, the ketogenic diet may help to stabilise brain function and reduce seizures.

Another theory is that the diet increases energy production in the brain, making neurons more stable. This is supported by research from Emory University, which found that the diet alters genes involved in energy metabolism in the brain. This, in turn, helps to stabilise the function of neurons exposed to the challenges of epileptic seizures.

A third theory suggests that the diet stops neurons from firing through the opening of certain ion channels in the cells. Ion channels are small pathways that allow ions such as sodium and potassium to move in and out of cells.

The ketogenic diet has been shown to be effective in treating epilepsy, especially in children. A 2019 review found that the keto diet reduced or prevented seizures in children and adults with drug-resistant epilepsy. The Epilepsy Foundation recommends the diet as a potential treatment, reporting that over half of children with refractory epilepsy who followed a ketogenic diet experienced a 50% reduction in seizures. Furthermore, around 10-15% of these children stopped having seizures altogether.

It is important to note that anyone using the keto diet to help control epilepsy should do so under medical supervision. This is to ensure that the person is dieting safely and getting the most benefits. Medical supervision is especially crucial for infants and children.
