What is a Low-Carb Diet?
A low-carb diet is a way of eating that limits carbohydrates, mainly sugars and starches. The goal is to decrease the body’s dependence on glucose for energy and promote the use of stored fat instead.
A low-carbohydrate diet typically involves consuming more protein and healthy fats to make up for the reduced carbs. This means consuming fewer grains, fruits, and starchy vegetables.
A low-carb diet can have benefits like weight loss, improved metabolic health, and better blood sugar control. However, individual responses may vary, so it’s important to choose a sustainable approach based on personal health goals and preferences.
There are different types of low-carb diets, with some moderately restricting carbohydrate intake and others, like the ketogenic diet, severely limiting carbs to induce and maintain ketosis. Other low-carb diets include:
General Low-Carb Diet
The low-carb diet doesn’t have a strict definition. It’s simply known as a diet with fewer carbs and more protein compared to a typical American diet.
This diet emphasizes foods such as lean meats, leafy greens, and healthy fats. You should limit your consumption of high-carb foods like grains, potatoes, sugary drinks, and junk foods.
Low-carb diets encompass a range of carb intake, typically between 50 to 150 grams per day. The amount of carbs you consume daily depends on your goals and preferences. As a general guideline, you can use something like this:
- 100ā150 grams: This range is for weight maintenance or frequent high-intensity exercise. Enjoy lots of fruit and even some starchy foods like potatoes.
- 50ā100 grams: This range is for slow and steady weight loss or weight maintenance. Make room for plenty of vegetables and fruit.
- Under 50 grams: This is for fast weight loss. Eat lots of vegetables but limit fruit to low-GI berries.
Low-Carb High-Fat Diet
LCHF stands for “low-carb, high-fat.” It’s a common very low-carb diet that emphasizes whole, unprocessed foods. The diet primarily includes meats, fish, shellfish, healthy fats, eggs, dairy, nuts, and berries.
This is similar to a ketogenic diet but with more flexibility in carbohydrate and protein intake. The recommended daily carb intake on this diet can range from 20 to 100 grams.
Low-Carb Paleo Diet
The paleo diet is widely adopted worldwide as it promotes consuming foods that were likely accessible during the Paleolithic era, before the agricultural and industrial revolutions.
According to advocates of the paleo diet, reverting to the eating habits of our prehistoric ancestors can enhance health. Some studies indicate that following this diet may lead to weight loss, lower blood sugar levels, and improve risk factors associated with heart disease.
Paleo isn’t strictly low-carb, but it usually ends up being that way. It focuses on meats, fish, seafood, eggs, vegetables, fruits, tubers, nuts, and seeds. By following a strict Paleolithic diet, you cut out processed foods, added sugar, grains, legumes, and dairy, which are also limited on a low-carb diet.
Low-Carb Mediterranean Diet
The Mediterranean diet is highly recommended, especially by health professionals. It is based on the traditional foods eaten in Mediterranean countries in the early 20th century.
Research indicates that this diet can potentially reduce the risk of heart disease, breast cancer, and type 2 diabetes. It consists of fish, olive oil, fruits, vegetables, whole grains, legumes, and nuts.
A low-carb Mediterranean eating pattern is based on the Mediterranean diet but restricts higher-carb foods such as whole grains. In contrast to a typical low-carb diet, it promotes consuming more fatty fish instead of red meat and extra virgin olive oil rather than fats like butter.
Atkins Diet
The Atkins diet is a well-known and long-standing low-carb eating plan. It focuses on reducing high-carb foods while allowing unlimited protein and fat intake. Initially, you follow a very low-carb approach and then gradually reintroduce carb sources such as vegetables and fruit.
The Atkins diets consist of four phases:
Induction: Consume fewer than 20 grams of carbs daily for two weeks.
Balancing: Gradually introduce more nuts, low-carb vegetables, and fruit.
Pre-maintenance: As you approach your weight goal, incorporate more carbs until your weight loss slows down.
Maintenance: Consume a suitable amount of healthy carbs without regaining lost weight.
Zero-Carb Diet
The zero-carb diet eliminates all carbohydrates and sugar from your diet. Some people believe that by cutting out carbs, they can achieve rapid weight loss, but there is no solid evidence to support this claim. There are also concerns about the potential impact of carb elimination on overall health.
This type of low-carb or keto diet is extremely restrictive, allowing only animal meat and fats. One drawback of this diet is its high saturated fat content and lack of fiber, which aids digestion. Additionally, it lacks vegetables, fruits, and essential vitamins, minerals, and antioxidants.
This diet restricting carbs completely is not advisable, even for healthy individuals, and should only be attempted with guidance from a healthcare professional.
What is a Keto Diet?
A ketogenic diet is a low-carb, high-fat diet often used for weight management and blood sugar regulation. A keto diet is essentially a low-carb diet with specific macronutrient ratios. It typically consists of around 70-75% of calories from fat, 20-25% from protein, and 5-10% from carbohydrates.
A ketogenic diet aims to reach the metabolic state of ketosis. In ketosis, the body converts fat into ketones, which it then uses as fuel. By significantly reducing carb consumption, the keto diet depletes the body’s glycogen stores, causing the liver to produce ketones from fat. These ketones become the primary source of energy for both the body and the brain during ketosis.
To achieve the metabolic state of ketosis, individuals following the keto diet should prioritize nourishing fats, lean meats, moderate protein, and low-carb vegetables.
The keto diet is popular for its potential benefits: rapid weight loss, improved blood sugar control, and increased mental clarity for some. However, it requires careful planning to ensure enough nutrients.
Ketogenic diets can also be divided into different types:
Standard Keto Diet (SKD)
When people discuss Keto, they usually refer to the standard keto diet or SKD. The SKD is a term used to describe a very-low-carb diet with the following macros:
- 55ā75% fat
- 15ā35% protein
- 0ā10% carbs
Maintaining specific macronutrient ratios causes a metabolic shift in your body. Instead of relying mainly on glucose for energy, your body starts using fat and ketones. By keeping carbs low, you also keep insulin levels low, promoting the burning of body fat.
Cyclical Keto Diet (CKD)
CKD is a modified version of the standard ketogenic diet. With CKD, you follow a standard keto diet for 5-6 days a week and then consume higher amounts of carbohydrates for 1-2 days.
Days with higher carb intake are called “refeeding days.” They replenish the body’s depleted glucose stores. In a cyclical ketogenic diet, you temporarily exit ketosis during refeeding days to benefit from consuming carbs.
CKD is ideal for individuals looking to boost muscle growth and exercise performance. Some believe this cyclic diet is more effective than the standard keto in increasing strength and building muscle.
Targeted Keto Diet (TKD)
If you’re struggling with reduced exercise performance on a keto diet, even with adequate sleep and electrolyte balance, a targeted keto diet could be a viable solution. It offers a middle ground between standard and cyclical keto diets by allowing limited carb intake.
During a TKD, consuming 15-50 grams of fast-absorbing carbs before, during, or after a workout can boost performance. These simple carbs can be sourced from real food, such as white rice or potatoes, or athletes may opt for dextrose (glucose) powder.
Consuming fast-absorbing carbs might temporarily disrupt ketosis. However, as these carbs are consumed during exercise, they are likely to be burned off swiftly. Afterwards, you can resume normal fat-burning.
Dirty Keto Diet
Dirty keto is a version of the SKD that heavily relies on processed foods lacking nutritional value. These foods often contain vegetable oils, artificial sweeteners, and processed meats. Consequently, the diet is deficient in essential nutrients such as vitamins, minerals, and fiber.
Like other types of keto, this diet focuses on low-carb, high-fat foods. The goal is to get 55-75% of daily calories from fats, 15-35% from protein, and keep net carbs below 10%. This usually means limiting carb intake to less than 20-50 grams per day.
Unlike SKD, dirty keto or lazy keto is not overly concerned with the specific source of macronutrients. It offers greater flexibility and affordability, making it accessible to many. However, the food choices often lack nutritional value, with higher amounts of sodium and unhealthy fats due to the inclusion of processed food and prepackaged snacks.
Other types of keto diets typically combine the SKD with other dietary plans like the keto carnivore diet, pescatarian keto, vegan keto, and whole-foods plant-based clean keto.
Pros and Cons of Low-Carb versus Keto Diets
When it comes to choosing between low-carb and keto diets, there are several factors to consider.
The main difference between these diets is carbohydrate intake. On a low-carb diet, you typically eat 50ā150 grams of carbs per day, but on the keto diet, daily carb intake is restricted to fewer than 50 grams.
Another main difference is protein intake. With low-carb diets, protein intake may be high, but with keto diets, protein intake should be moderate at around 20% of total calories. This is because excessive protein intake can prevent ketosis.
Additionally, fat intake tends to be significantly higher on the keto diet, as fats replace carbs and protein.Ā
Low-carb diets have advantages and disadvantages. On the positive side, they can aid in weight loss, eliminate processed high-carb foods, and can be followed long-term. Furthermore, they have a typically easier adaptation phase compared to keto and are generally less restrictive and easier to follow.
However, there are a few side effects to consider. You might feel weak or have constipation, and low-carb diets restrict food choices and fruit consumption. Additionally, they can affect the intake of essential nutrients.
The keto diet also has its pros and cons. It provides health benefits such as managing epilepsy, improving insulin sensitivity, reducing appetite, and enhancing cholesterol and triglyceride levels.
However, there are some drawbacks to consider. Common issues include constipation due to low fiber intake, limited long-term data, and the risk of experiencing the keto flu, which can cause headaches, fatigue, brain fog, irritability, and lack of motivation.
Also, the diet restricts fruit intake and can be a bit challenging to stick with for extended periods. Overall, keto might be too strict for most people, making it hard to follow in the long run.
Low-Carb versus Keto: Who Should Follow a Low-Carb or Keto Diet
Low-carb and keto diets can work for some people, but it’s important to think about your own health goals, preferences, and medical conditions. Here are a few situations where these diets might be worth considering:
Weight Loss Goals: Both low-carb and keto diets have been linked to successful weight loss. If you’re aiming to lose weight and body fat, these dietary approaches could work for you.
Improving Metabolic Health: Low-carb diets have proven to enhance insulin sensitivity, blood sugar control, and lipid profiles. These benefits are particularly valuable for individuals with insulin resistance, metabolic syndrome, or type 2 diabetes.
Epilepsy Treatment: The keto diet has been used for a long time to manage epilepsy, especially in children who may not respond well to medication.
Neurological Conditions: Research indicates that a ketogenic diet could have potential benefits for specific neurological conditions like Alzheimer’s disease and Parkinson’s disease. However, further studies are necessary to gain a better understanding in this field.
Endurance Athletes: Some endurance athletes try low-carb or keto diets to enhance fat adaptation and endurance performance. However, it’s important to note that individual responses can vary, and this approach may not be suitable for all athletes.
It’s important to consult with healthcare professionals or nutritionists before starting low-carbohydrate diets, especially if you have pre-existing medical conditions or concerns.
