Low-Carb Lifestyle: Avoiding Keto Strictness

The ketogenic diet, or keto, is a very low-carb, high-fat diet that has gained popularity in recent years. While keto restricts carb intake to 50 grams or fewer per day, a low-carb diet typically allows for 50-150 grams of carbs per day. This means that on a low-carb diet, you can still enjoy some carbs, such as fruits and vegetables, without having to cut them out completely.

A low-carb diet can be a good option for those who want to reduce their carb intake but don't want to go as extreme as keto. It may be easier to stick to in the long term and can still lead to weight loss and improved health. However, it's important to note that simply reducing carbs may not be enough to achieve ketosis, a state where your body uses fat as its main fuel source instead of carbs.

Before starting any diet, it's recommended to consult a healthcare professional to ensure it's safe and suitable for your individual needs and health status.

A low-carb diet can be sustained long-term, unlike keto

Low-carb diets have been popular for years, from the Atkins diet to the keto craze. But what happens when you cut out carbs for the long haul? Is it a viable, healthy option?

The basics of a low-carb diet

At its core, a low-carb diet limits the intake of carbohydrates, typically found in foods like grains, starchy vegetables, and fruits. Instead, it emphasizes the consumption of protein and healthy fats. Studies suggest that a low-carb diet comprises 10–30% of calories from carbs, although there is no set definition. For a healthy person who consumes 2,000 calories per day, this equals 50–150 grams of carbs.

The pros of a low-carb diet

A low-carb diet has been linked to several health benefits, including weight loss, improved skin health, and reduced risk of chronic diseases such as type 2 diabetes and dementia. It eliminates many processed high-carb foods and can be sustained long-term. It has a less extreme adaptation phase than keto, is less restrictive, and is easier to follow.

The cons of a low-carb diet

You may feel weak or experience constipation. It may impact micronutrient intake, and it can be tough to stick to. There may be unpleasant side effects like bad breath and constipation. Plus, if you're not careful, you could miss out on important nutrients like fiber and certain vitamins.

The basics of a keto diet

The keto diet is a very low-carb, high-fat diet. When following a keto diet, the goal is to reach nutritional ketosis, where your body produces ketones from fat in your liver and uses fat as its main fuel source instead of carbs. This is achieved by consuming fewer than 50 grams of carbs per day while keeping protein intake moderate and increasing fat intake drastically.

The pros of a keto diet

The keto diet has several therapeutic properties, such as helping treat refractory epilepsy and potentially impairing the growth of certain types of cancer. It may also improve insulin sensitivity, reduce appetite, and improve cholesterol and triglyceride levels.

The cons of a keto diet

Constipation is common due to the low fiber intake. Long-term data is limited, and it may be difficult to stick to for long periods. The keto diet is more restrictive and may be too extreme for most people, leading to poor long-term adherence. It is also associated with an increased risk of "keto flu," which includes symptoms such as headaches, fatigue, brain fog, irritability, and lack of motivation.

Why a low-carb diet is more sustainable

While both diets limit carbs to varying degrees, the keto diet is more restrictive and extreme. For most people, the low-carb diet appears to be more sustainable in the long term. It allows for more flexibility in food choices and is less likely to lead to an all-or-nothing mentality if you slip up. It also tends to be less expensive, as it doesn't require the purchase of expensive low-carb snacks and high amounts of meat.

In conclusion, while both diets have their pros and cons, a low-carb diet is generally more sustainable and easier to follow than a keto diet. It offers many of the same health benefits, such as weight loss and improved insulin sensitivity, without the extreme restrictions and potential side effects of keto.

You can still eat fruit and vegetables on a low-carb diet

Yes, you can still eat fruit and vegetables on a low-carb diet.

Low-carb diets are a popular way to lose weight and improve health, but they don't have to be overly restrictive. While some low-carb diets, like the ketogenic diet, recommend severely limiting carbohydrates, it is possible to follow a low-carb diet that includes fruits and vegetables.

Fruits and vegetables are excellent sources of essential vitamins, minerals, and fibre, and can help reduce the risk of chronic diseases. They are also generally low in fat and calories, making them a good choice for people watching their weight.

When it comes to fruits, it is best to choose lower-carb options such as berries, avocados, peaches, and melons. These fruits have a lower carbohydrate content and a higher amount of fibre, which can help reduce the number of net carbs. For example, 100 grams of strawberries have 7.68 grams of carbohydrates and 2 grams of fibre, resulting in a net of 5.68 grams of carbohydrates.

As for vegetables, non-starchy vegetables are the way to go. Options like cucumbers, lettuce, celery, mushrooms, spinach, and broccoli are all low in carbs and high in nutrients. For example, 100 grams of cucumbers (peeled) contain just 2.16 grams of carbs.

By incorporating these low-carb fruits and vegetables into your meal plan, you can still enjoy the health benefits of these foods while sticking to your low-carb goals. It's important to note that the specific amount of fruits and vegetables you can include will depend on your daily carb limit and overall health goals. Consulting with a healthcare provider or dietitian can help determine the right approach for your situation.

A low-carb diet is less restrictive and easier to follow than keto

Low-carb diets are less restrictive than keto diets as they allow for more carbohydrate options and do not require the same level of tracking and precision as keto. On a low-carb diet, you can still enjoy a variety of fruits, vegetables, and whole grains, whereas on keto, even certain fruits and vegetables become off-limits. For example, a single medium-sized banana contains about 27 grams of carbs, which is close to the daily limit for keto.

Low-carb diets are also easier to follow because they are more flexible and do not require strict adherence to specific macronutrient ratios. This means that you don't have to track your fat and protein intake as closely as you would on keto. Falling off the wagon with a single high-carb meal on keto can result in a return to former poor eating habits, whereas a low-carb diet provides more wiggle room and is less likely to result in an "all-or-nothing" mentality.

Additionally, low-carb diets tend to be more economical than keto diets. Keto diets often require expensive grocery bills, as they focus on meat and expensive low-carb snacks. In contrast, low-carb diets allow for inexpensive, easily portable, and nutritious carbohydrates like bananas, rice, or beans.

Furthermore, low-carb diets are less likely to distort a person's sense of what is "healthy" or "unhealthy" to eat. On keto, all carbohydrates are restricted, including healthy options like apples, lentils, bananas, and brown rice. This can make it challenging to determine what constitutes a healthy meal or snack. A low-carb diet provides more flexibility and allows for a greater variety of nutritious foods.

Finally, a low-carb diet can be beneficial for weight loss, diabetes, and cardiovascular risk, even if a person does not enter ketosis. By focusing on limiting processed carbs and added sugars, a low-carb diet can help manage weight and improve health.

In summary, a low-carb diet is less restrictive and easier to follow than keto. It provides more flexibility, is more economical, allows for a greater variety of nutritious foods, and can lead to similar health benefits without the strict requirements of ketosis.

You may experience constipation on a low-carb diet

Constipation is a common side effect of starting a low-carb or keto diet. It occurs when you have three or fewer bowel movements per week. It may also cause your stools to become hard and lumpy and difficult to pass.

Causes of Constipation on a Low-Carb Diet

There are several reasons why you may experience constipation when following a low-carb diet:

• Adjustment to fewer carbs and more fat: Carbohydrates like fruits and whole grains are common sources of fiber, so transitioning to a low-carb diet can lead to a sudden decrease in fiber intake, causing digestive issues like constipation.
• Difficulty transitioning to a high-fat diet: Some people may struggle to adjust to the very high-fat content of a keto diet, which can also cause gastrointestinal upset.
• Reduction in fiber intake: Since high-carb, fiber-rich foods like fruits, whole grains, and starchy vegetables are restricted on a keto diet, it can be challenging to consume enough fiber, which is essential for maintaining healthy bowel movements.
• Dehydration: The transition to a very low-carb diet can cause an increase in urination, leading to mild dehydration, which is associated with constipation.
• Change in body electrolytes: Alterations in body electrolytes can impact stool frequency.
• Caloric decrease: Low-carb diets often result in a natural caloric decrease, which can lead to a reduction in stool volume or frequency.

Preventing and Treating Constipation on a Low-Carb Diet

• Stay hydrated: Drink enough water to prevent dehydration, which is a potential cause of constipation. Aim for clear urine, and limit caffeinated drinks, which can contribute to dehydration.
• Increase salt intake: Consuming adequate salt can help with fluid retention and dehydration prevention. A good starting point is between 4 and 6 grams of sodium per day (about 2.5 teaspoons).
• Eat more fiber: Focus on consuming high-fiber, low-carb foods like above-ground vegetables, nuts, and seeds. The Academy of Nutrition and Dietetics recommends 25 grams of fiber per day for women and 38 grams for men.
• Take magnesium supplements: Magnesium is a known laxative and is often recommended to treat constipation. Start with a lower dose (around 200-400 mg) and increase if needed, but be cautious as higher doses may cause loose stools or diarrhea.
• Add MCT oil: Medium-chain triglyceride (MCT) oil can help promote ketosis and stimulate gut motility and bowel movements. Start with a small amount (1-2 tablespoons) and increase gradually if needed.
• Increase physical activity: Regular physical activity may help improve constipation and has additional health benefits.

If constipation persists despite these interventions, over-the-counter stool softeners or laxatives may be an option. However, it is important to follow the package directions and warnings and consult a doctor if constipation becomes a persistent issue.

A low-carb diet may not be suitable for everyone

A low-carb diet can be a great way to lose weight and improve health, but it may not be suitable for everyone. While most people can safely start a low-carb diet, there are some groups who may need to adapt it or avoid it altogether.

Who should not do a low-carb diet?

Those taking medication for diabetes or high blood pressure, and those who are breastfeeding, may need to adapt a low-carb diet to suit their needs. It is important to discuss any dietary changes with a doctor to ensure medication doses can be adjusted if necessary.

Additionally, those following a vegetarian or vegan diet may struggle to reduce their carb intake, as some plant-based protein sources such as chickpeas and lentils are naturally high in carbohydrates. It is possible for vegetarians and vegans to follow a low-carb diet, but careful planning is required to ensure an adequate nutritional balance is maintained.

Potential health risks

A low-carb diet may also carry some health risks, particularly if followed long-term. Short-term health risks may include reduced athletic performance, while long-term risks may include nutritional deficiencies, loss of bone density, and gastrointestinal problems.

Furthermore, a low-carb diet can be challenging to stick to, especially at the beginning. Some people may feel weak or experience constipation due to the reduced intake of certain micronutrients.

Alternatives to a low-carb diet

For those who find a low-carb diet unsustainable, there are alternative options for weight loss and health improvement. A balanced diet based on good nutritional foundations is always recommended. Prioritising protein and filling the rest of the calorie budget with fats and carbs can be an effective strategy for weight loss and maintenance.

Additionally, simply reducing sugar intake can be an easier way to cut calories without the restrictions of a low-carb diet. This can be done by focusing on whole foods such as fruits, vegetables, and whole grains, rather than processed carbohydrates and sugary snacks.

Overall, while a low-carb diet can be beneficial for some people, it may not be suitable or necessary for everyone. It is important to consult a healthcare provider before starting any new diet to ensure it is safe and appropriate for your individual needs and goals.
