The Ketogenic Diet: A Detailed Keto Guide for new Beginners
The keto diet, also known as the ketogenic diet, is a dietary approach characterized by low carbohydrate intake and high fat consumption, which has been shown to provide numerous health advantages.
Research studies have consistently demonstrated that this particular diet can effectively aid in weight loss and promote overall improvements in health. Furthermore, ketogenic diets have been associated with potential benefits in managing conditions such as diabetes, cancer, epilepsy, and Alzheimer's disease.
For individuals who are new to the keto diet, a comprehensive beginner's guide has been prepared to offer detailed information and guidance.
Keto basics
The ketogenic diet is a high fat, very low carb eating plan that shares several similarities with both the Atkins and low carb diets.
Its primary principle involves a substantial reduction in carbohydrate intake, with the goal of prompting a metabolic state known as ketosis. In ketosis, the body becomes remarkably efficient at utilizing fat as its primary source of energy. Additionally, the liver converts fat into ketones, which can serve as an energy supply for the brain.
Ketogenic diets have been shown to lead to significant decreases in blood sugar and insulin levels. These effects, combined with the elevated ketone production, contribute to various health benefits.
SUMMARY
The keto diet: Low carb, high fat. Lowers blood sugar, insulin; shifts metabolism from carbs to fat and ketones.
Different types of ketogenic diets
The ketogenic diet exists in various versions, including:
Standard Ketogenic Diet (SKD): This version involves consuming a very low amount of carbohydrates, a moderate amount of protein, and a high amount of fat. Typically, it consists of 70% fat, 20% protein, and only 10% carbohydrates (9Trusted Source).
Cyclical Ketogenic Diet (CKD): This diet incorporates alternating periods of higher carbohydrate intake, such as following 5 days of following a ketogenic diet with 2 days of consuming a higher amount of carbohydrates.
Targeted Ketogenic Diet (TKD): With this diet, individuals are allowed to consume additional carbohydrates around their workout sessions to support their exercise performance.
High Protein Ketogenic Diet: Similar to the standard ketogenic diet, this version emphasizes a higher protein intake. The macronutrient ratio often consists of 60% fat, 35% protein, and 5% carbohydrates.
However, it's important to note that extensive research has primarily focused on the standard and high protein ketogenic diets. Cyclical and targeted ketogenic diets are considered more advanced methods and are predominantly utilized by bodybuilders or athletes.
While the information in this article mainly pertains to the standard ketogenic diet (SKD), many of the fundamental principles can be applied to the other versions as well.
SUMMARY
Multiple versions of the keto diet exist. The extensively studied and commonly recommended variant is the standard ketogenic diet (SKD).
Ketosis refers to a metabolic state in which the body utilizes fat as its primary source of fuel instead of carbohydrates.
This state is achieved by significantly reducing carbohydrate intake, thereby limiting the body's supply of glucose, which is the main energy source for cells.
To induce ketosis effectively, following a ketogenic diet is recommended. This typically involves restricting carbohydrate consumption to approximately 20 to 50 grams per day and prioritizing fats from sources such as meat, fish, eggs, nuts, and healthy oils.
It is important to moderate protein intake as well since excessive protein consumption can be converted into glucose, potentially slowing down the transition into ketosis.
In addition to dietary changes, practicing intermittent fasting can help expedite the process of entering ketosis. Various forms of intermittent fasting exist, but a common approach involves restricting food intake to an 8-hour window each day and fasting for the remaining 16 hours.
To determine whether ketosis has been achieved, blood, urine, and breath tests are available, which measure the levels of ketones produced by the body.
Certain symptoms can also indicate the onset of ketosis, including increased thirst, dry mouth, frequent urination, and reduced hunger or appetite.
SUMMARY
Ketosis: Body uses fat, not carbs, as fuel. Diet modification, intermittent fasting aid quicker ketosis. Tests, symptoms assess ketosis status
Can ketogenic diets help you lose weight?
The ketogenic diet has proven to be a highly effective approach for weight loss and reducing risk factors associated with various diseases.
Research indicates that the ketogenic diet can be as effective for weight loss as low-fat diets. Furthermore, the diet's satiating nature allows individuals to shed pounds without the need for calorie counting or meticulous food tracking.
A comprehensive review of 13 studies revealed that following a very low-carb, ketogenic diet was slightly more successful in achieving long-term weight loss compared to a low-fat diet. On average, participants on the keto diet lost around 2 pounds (0.9 kg) more than those on the low-fat diet. Additionally, the ketogenic diet led to reductions in diastolic blood pressure and triglyceride levels (13Trusted Source).
Another study involving 34 older adults found that individuals on a ketogenic diet for 8 weeks lost nearly five times more total body fat compared to those on a low-fat diet (17Trusted Source).
The increased production of ketones, lower blood sugar levels, and improved insulin sensitivity are thought to contribute significantly to these weight loss outcomes.
For more in-depth information on the weight loss effects of the ketogenic diet, I recommend reading the referenced article.
A ketogenic diet aids greater weight loss than low fat diet, often with reduced hunger.
Ketogenic diets for diabetics and prediabetics
Diabetes is characterized by metabolic changes, high blood sugar levels, and impaired insulin function. The ketogenic diet has shown potential in addressing conditions like type 2 diabetes, prediabetes, and metabolic syndrome by aiding in weight loss and improving various markers associated with these conditions.
An older study demonstrated that the ketogenic diet could improve insulin sensitivity by an impressive 75%. Additionally, a small study involving women with type 2 diabetes found that following a ketogenic diet for 90 days significantly reduced levels of hemoglobin A1C, a measure of long-term blood sugar management.
In a study involving 349 individuals with type 2 diabetes, those who adhered to a ketogenic diet experienced an average weight loss of 26.2 pounds (11.9 kg) over a 2-year period. This weight reduction is noteworthy given the strong correlation between weight and type 2 diabetes. Moreover, participants demonstrated improved blood sugar control, leading to a decrease in the use of certain blood sugar medications throughout the study (27Trusted Source),(27Trusted Source),(27Trusted Source)
For more detailed information, I recommend referring to the provided article on the benefits of low-carb diets for individuals with diabetes.
SUMMARY
The ketogenic diet enhances insulin sensitivity, promotes fat loss, benefiting individuals with type 2 diabetes or prediabetes.
What are the other health benefits of keto?
The ketogenic diet originated as a therapeutic approach for epilepsy, but its potential benefits have extended to various health conditions:
Heart disease: The ketogenic diet can improve risk factors such as body fat, HDL (good) cholesterol levels, blood pressure, and blood sugar.
Cancer: It is being investigated as an adjunct treatment for cancer due to its potential in slowing tumor growth.
Alzheimer's disease: The keto diet may help reduce symptoms and slow the progression of Alzheimer's disease.
Epilepsy: Significant reductions in seizures have been observed in epileptic children following the ketogenic diet.
Parkinson's disease: Although more research is needed, one study found that the diet helped improve symptoms of Parkinson's disease.
Polycystic ovary syndrome (PCOS): The ketogenic diet can aid in reducing insulin levels, which may be beneficial for PCOS management.
Brain injuries: Initial research suggests potential improvements in outcomes for traumatic brain injuries with the ketogenic diet.
It is important to note that conclusive evidence is still lacking in many of these areas, and further research is needed to establish definitive conclusions regarding the efficacy of the ketogenic diet for these conditions.
